Operating Instructions, 05/2012, A5E02254228-04 27
● Independent calibration of SIFLOW FC070 and the sensor guaranteeing the same
measuring accuracy if e.g. the function module is replaced. The calibration data of the
sensor as well as the user settings are saved in a SENSORPROM which can be used
further if the module is replaced. The data are thus retained. The calibration data for the
function module are stored in the FLASH of the SIFLOW FC070 itself.
● Encrypted backplane communication between SIFLOW FC070 and Siemens operating
panel using OCX ActiveX component
3.4 Theory of operation
The flow measuring principle is based on the Coriolis law of motion.
Particles moving in a rotating/oscillating system will resist the imposed oscillations in a manner
consistent with the mass and velocity (momentum). Oscillations produced by a Coriolis
flowmeter as the process media is accelerated around bends result in phase distortions of the
measuring tubes.
The SITRANS F C sensors are energized by an electromechanical driver circuit which
oscillates the pipe at its resonant frequency. Two pickups, S1 and S2, are placed symmetrically
on either side of the driver.
When the media flows through the sensor, Coriolis force will act on the measuring tube and
cause a tube deflection which can be measured as a phase shift between pickup S1 and pickup
S2.
The phase shift is proportional to the mass flowrate. The frequency and amplitude of the driver
are automatically regulated to ensure a stable output from the 2 pickups in the region of 80 to
120 mV. The temperature of the sensor tubes is measured by a Pt1000, in order to enable
accurate compensation for changes in the material stiffness. As a result the process media
temperature is also accurately measured.
The flow proportional phase signal from the pickups, the temperature measurement and the
driver frequency enable calculation and reporting of mass, density, volume, and temperature.
SENSORPROM
All SITRANS F C Coriolis flowmeters feature a SENSORPROM memory unit which stores
sensor-specific calibration data and transmitter settings for the lifetime of the product. The
factory settings matching the sensor are stored in the SENSORPROM. At commissioning the
flowmeter commences a typical flow measurement without any initial programming. Also
customer-specified settings are downloaded to the SENSORPROM.

4.2 DIP switches
4.2.1 MODBUS address switch
The SIFLOW FC070 module has two DIP switches located on the side of the SIFLOW function
module enclosure: the MODBUS slave address switch and the write protection switch.
:3212))02'%86$''5(66
Figure 4-1 Write protection (WP) and Modbus address switches
4.2.2 MODBUS slave address
For communication over MODBUS, the associated MODBUS slave address must be set. Using
this address, the SIFLOW FC070 function module can be individually addressed by the
MODBUS master.
Two options are available for setting the MODBUS slave address:
● Set "0" on the DIP switch if you wish to set the MODBUS slave address with PDM or
SIMATIC. The function module starts up with default slave address = 1. The connection
must first be established point-to-point with slave address "1". Then the slave address can
be changed via SIMATIC PDM or via SIMATIC S7 in HW-Config (basic parameter "Device
Address").
Set "1...247" on the DIP switch if you wish to set a fixed (hardware-defined) MODBUS slave
address (slave address from SIMATIC PDM or SIMATIC S7 will be ignored).

4.2.3 Write protection
Next to the MODBUS slave address switch, the write protection switch is present in a further
cutout. The write protection switch is the furthest switch on the left. The other two switches are
not used and should be left "OFF".
By activating this write protection the parameters can only be read from the device. Using the
switch, you can prevent firmware updates from being transferred unintentionally to the function
module.
With "ON", the write protection is active.
4.3 Assembly on the rail
SIFLOW FC070 is a function module of the SIMATIC S7-300 system, and can be directly

Programming in SIMATIC S7 7
This chapter describes how to communicate with the function module by use of the S7 function
blocks and data blocks provided with the module.
7.1 SIFLOW FC070 in the cyclic S7 program
Within the S7-300/400 automation system the data exchange takes place trough FB95
SIFL_FC function block supplied with the module.
The function block SIFL_FC (FB95) is not present in the S7 block library, but is subsequently
installed using a setup procedure described in chapter "Installation" (Page 49). In addition to
the function block FB95, the setup contains:
● Online help for the function block
● Two associated data blocks DB_FLOW_PARA (DB17) and DB_FLOW_VEC (DB16)
● The user-defined data type UDT_SIFL_FC (UDT18)
● User documentation
Function block and data block
The function block and the two data blocks in S7 provide you with a user interface to the
sensors.
You insert the function block SIFL_FC in the user program and write data to the inputs and
outputs of the function block (call parameters). While programming the call, an instance data
block is created for the FB SIFL_FC. Besides the instance data block, a parameter DB
(DB_FLOW_PARA) is required for every SIFLOW FC070, in which the parameters are stored.
The UDT that comes with it can also be used for creating the parameter DB.
The vector DB (DB_FLOW_VEC) must also be loaded in the SIMATIC CPU. A vector DB can
be used by more than one SIFLOW FC070.
Reading parameters
Before any parameterization it is necessary to read all parameters from SIFLOW FC070 into
the data block DB_FLOW_PARA, as the data block only contains default data and not sensor-
specific data. Sensor-specific data are comprised in the SENSORPROM unit.
SIFLOW FC070 with SIMATIC S7
Operating Instructions, 05/2012, A5E02254228-04 57
SIFLOW FC070 in the HW Configuration
During project planning for the hardware configuration in the SIMATIC manager, the basic
properties of the module are defined:
● The peripheral address of the module
● Diagnostic alarm enable
● Process alarm enable
● Behavior for CPU stop
The basic parameters are transferred to the function module during each restart and STOP/
RUN transition of the CPU. Changes to parameters on the programming device must be
compiled and written to the CPU.
7.2 Functions of the S7 function block SIFL_FC (FB95)
The FB SIFL_FC supports you during operation of the SIFLOW FC070 function module for
industrial flow measurements according to the Coriolis principle. The following functions are
offered:
● Read data record
● Write data record including handshake
● Select two readable process values
● Error queue with acknowledgment processing
● Synchronized indication of data and operating errors (after sending the command or data
record to the function module)
● Write parameters using the block
● Send process commands including handshake
● Control both digital outputs
● Consistent reading back of the two selected process values and the status of the function
module
● Start up synchronization
● Lifebit monitoring and controlling
● Protection against modifications (closed FB)
● Multi-instance capability
Note
The FB does not evaluate any diagnostics messages

7.3 The data block DB_FLOW_PARA
Requirement
When programming the call in the SIFL_FC, an instance data block is created for the SIFL_FC.
In addition to the instance data block, a parameter data block DB_FLOW_PARA (DB17) is
required for each SIFLOW FC070 function module, and the parameters for the flow
measurement are stored in it. The provided UDT_SIFL_FC (UDT18) can be used to create the
parameter DB.
In addition, the vector data block DB_FLOW_VEC (DB16) which contains the general structure
of the DB_FLOW_PARA must be loaded in the S7 CPU. Only one DB_FLOW_VEC is required
per S7 CPU.
Basic functionality of data block DB_FLOW_PARA
The data block DB_FLOW_PARA contains the parameters and data provided for the flow
measurements and combined in data records (DR).
All data records in the function block SIFL_FC (FB95) which are read from the function module
by means of command codes 200…399 and 600…649 are saved in the data block
DB_FLOW_PARA.
All data records in the function block SIFL_FC (FB95) which are written to the function module
by means of command codes 400…599 and 650…699 are obtained from the data block
DB_FLOW_PARA.
Data records 2 to 12 and 39 (parameters) can be read as well as written. Data records 30 to
37 (process data) can only be read from the function module.
In addition to the data records, the data block DB_FLOW_PARA also contains the call
parameters of the function block SIFL_FC (FB95). By linking the corresponding inputs and
outputs of the FB and DB, it is possible for users to write the inputs of the FB with the current
data from the DB when calling the FB, or to write the data from the FB into the DB.
NOTICE
You can change the contents (the parameter values) of the parameter DB, but not its length
and structure.

SIFLOW FC070 with SIMATIC S7
Operating Instructions, 05/2012, A5E02254228-04 59
Calling parameters of the function block
Using the call parameter CMD_IN you can control all commands, whether for transmission of
a data record or execution of a batch command. You provide the command code using this
variable, and trigger the command by means of the variable CMD_EN = 1. The FB SIFL_FC
does not delete the command code, but resets the trigger variable CMD_EN after execution
of the command.
Set-up of SIFL_FC (FB95) function block
Data exchange with the SIFLOW FC070
SIFL_FC must be called once for every
SIFLOW module in the hardware configuration.
The ADDR is unique for every module.
For every SIFL_FC there must also be a
DB_FLOW_PARA
DB_VECTOR exists only once in a system
regardless of how many modules.
The call shown is a typical configuration of
SIFL_FC for most applications.
It covers:

(Page 156) and table "Sensor errors and process errors" (Page 152).
FB_ERR OUTPUT BOOL Error not signaled by SIFLOW FC070 but detected by the FB itself. Is
set for one cycle if a static error arrives or returns to normal. If a
processing error occurs for FB SIFL_FC, we have to assume that the
variables that have been output do not correspond with the actual status
in the module. For number of FB error, see FB_ERR_C:
● 1: static error present

Additional parameters in data block DB_FLOW_PARA (Page 66)
7.4 Functions of data block DB_FLOW_VEC
The vector data block DB_FLOW_VEC (DB16) contains the pointers to the data records in the
DB_FLOW_PARA and the commands entered there which are to be executed.
You need only download the vector DB into the S7 CPU so that the FB SIFL_FC can use the
information entered there. The vector DB is irrelevant for the further creation of your user
program because the program accesses the CPU memory area using a symbolic access
function.
NOTICE
Do not change the content, length and structure of the vector DB.
It need only be loaded once for each S7 CPU, independent of the number of SIFLOW FC070
function modules deployed.
You can freely select the number of the DB_FLOW_VEC.

Note
The data records listed above are described in detail in the following sections. Please note
that the min./max. values integrated in the tables for better clarity are present in separate
data records. The relationship between a data record and its associated min./max. values is
as follows:
● min. values: DR No. + 40 corresponds to the associated "Min." data record;
● max. values: DR No. + 80 corresponds to the associated "Max." data record.
Example: for data record 4, the min. values are in DR 44, and the max. values in DR 84.
The min./max. values are only module-internal values, i.e. the user program has no access
to the min./max. data records.

LED DO1 is lit while the batch is running.
The progress of the batch procedure is indicated on output VAR2_VAL. When Totalizer 2 on
output VAR2_VAL reaches the batch quantity, LED DO1 is switched off. The current massflow
remains on output VAR1_VAR.
This means that the total time for the batch procedure can be calculated from the following
formula: T = Batch quantity / massflow

Commissioning with SIMATIC PDM 8
8.1 General instructions
SIMATIC PDM is a software package for configuring, parameterizing, commissioning and
maintaining devices (e.g. transducers) and for configuring networks and PCs.
Among other features, SIMATIC PDM contains a simple process monitoring of the process
values, interrupts and status/diagnosis signals of the device.
Requirements
The following procedures must be completed before commissioning:
● Installation of SIMATIC PDM and SIFLOW FC070 PDM driver. (See also "Installation"
(Page 52)).
● Connection of Modbus interface. (See also "Connecting" (Page 45)).
Step-by-step guide to commissioning with PDM
The following steps show an example of how commissioning the SIFLOW FC070 can be
performed.
NOTICE
The example only covers measurement of massflow, but equal parameters exist for all other
measurements.
The steps are divided into the following sections:
1. Configuration describes the setup of the basic parameters of the flowmeter.
Step 1 in this section (read all parameters from SIFLOW) must be carried out before
changing any parameters.
2. System optimization describes how to optimize the system to gain better performance and
precision. This section must be performed if an optimization of the system is needed.
3. Operation describes how to view all available process values.

STEP 4 View process variable OPERATION
SIFLOW FC070 with SIMATIC S7
Operating Instructions, 05/2012, A5E02254228-04 77
8.2 Step 1: Reading parameters from SIFLOW FC070
Before any parameterization is done it is necessary to read all parameters from the SIFLOW
module into the offline table of SIMATIC PDM. This is necessary because the offline table
merely contains default data.
1. Open the PDM device driver.
2. Select "Device->Upload to PC/PG .." Select "Execute even if the device TAG does not
match the project data TAG." and click "OK" to read all parameters to the offline table. After
closing the dialog all loaded parameters should show "Loaded" in the status of the PDM
table.
8.3 Step 2: Setting basic parameters
In any application, the following must be defined before the parameters are configured:
● Measurement range of the application (min - max)
● Unit for the measurement range
Depending on the application, measurement range and measurement units, the following
parameters may need to be changed:
● Massflow unit
● Massflow upper value
● Massflow lower value
Example
● Measurement units must be kg/h
● Mass flow upper value must be 250 kg/h.
● Mass flow min must be 0 kg/h.
The following screen print shows the changes in the PDM table:

8.3 Step 2: Setting basic parameters
SIFLOW FC070 with SIMATIC S7
78 Operating Instructions, 05/2012, A5E02254228-04
Setting the basic parameters
1. Change the settings of the measurement parameters in the Output → Mass Flow folder (see
above) to appropriate values.
2. Select: "Device → Download to device...".
3. Select "Execute even if the device TAG does not match the project data TAG" and click
"OK" to download all parameters from the table to the device.
Note
If the SF LED on the SIFLOW module is red, a system failure has occured.
Refer to the chapter "Troubleshooting/FAQs" (Page 171) and make sure the problem is
resolved before continuing the commissioning.
8.4 Step 3: System optimization
The flowmeter system is optimized through a zero point adjustment.
Performing a zero point adjustment
1. Install shut-off devices in the pipeline. If possible, both upstream and downstream of the
sensor. Otherwise:
- in horizontal installations at the outlet
- in vertical installations at the inlet.
2. Pump liquid at max. flow through the sensor (at least 2 min) in order to avoid air in the liquid.
3. Stop the flow while pumping by shutting off the outlet valve and then the inlet valve. Wait
at least 1 min. In this way there will be zero flow but the liquid remains pressurized within
the sensor, hindering de-gassing of the liquid, i.e. the release of air or other gas from the
liquid.
Note
The flow must be completely stopped and the sensor completely filled with liquid.
4. Select "Device → Zero adjust" from the main menu of SIMATIC PDM to perform an
automatic zero point adjustment.
An online menu will appear where appropriate parameters can be configured and automatic
zero point adjustment performed.
5. Start the zero point adjustment by clicking "Auto zero adjust". When the zero point
adjustment has finished, a message box will show the result of the zero point adjustment.
Note
If you get an error message after the zero point adjustment, refer to the chapter
"Troubleshooting/FAQs" (Page 171).

This chapter provides a step-by-step guide on how to make the initial set-up of SIFLOW FC070
non-Ex and Ex in a S7-300/400 environment.
The chapter refers to a PLC example code from SIFLOW getting started package found on
the CD provided with the product.
After finishing the steps, the system is ready to go into normal operation.
Note
The steps described within this chapter must always be carried out regardless of the
application intended.
Requirements
It is assumed that the user is familiar with the SIMATIC Manager environment and has carried
out the steps mentioned below:
● Installed the measurement system consisting of a SIFLOW FC070 and a sensor. (See
"Hardware installation and removal (Page 29)")
● Installed the S7 library. (See "Software installation (Page 49)")
● Installed the HSP package. (See Software installation (Page 49)")
9.1 Setting the basic parameters in the HW-Config
Set the static basic parameters as follows:
Add SIFLOW FC070 module to the HW config by dragging and dropping the module into the
rail with S7-300 CPU or ET-200M (see Installation of S7 Hardware support package
(Page 49)).
1. Select SIFLOW function module in HW-Config, and then the menu command Edit > Object
properties.
2. In the Basic parameters tab, enter the following static basic parameters.

Note
Make sure that you assign identical values to the start addresses of the output and input data
areas for each SIFLOW FC070.
Note
Make sure that you assign a different device address to each function module if several
modules are used in the rack or on the MODBUS.
Diagnostics interrupt
If you enable the diagnostics interrupt, any diagnostics information present is entered into the
diagnostics data record and triggers a diagnostics interrupt (OB82).
Process interrupts
If you enable the process interrupts, you can parameterize 8 process interrupts in data record
7. Certain events in the process trigger a process alarm, e.g. upward or downward violation
of a limit, and the OB40 is called.

9.2 Step-by-step guide to commissioning with S7
The following step-by-step example refers to the demo software provided with the getting
started package.
In the example it is assumed that:
● The sensor is an FC300 DN 4
● The SIFL_FC S7 library is used "as is" (no renaming of FB’s and DB’s)
– FB95 = SIFL_FC
– DB17 = DB_FLOW_PARA
– DB16 = DB_FLOW_VECTOR
Note
The example only covers measurement of mass flow, but equal parameters exist for
all other measurements.
Contents
The steps are divided into the following sections
● The section "Configuration" describes how to set up the basic parameters of the flowmeter.
Step 1 in this section (read all parameter from SIFLOW) should always be carried out before
changing any parameter in the module.
This section can be carried out in PDM or in S7.
● The section "System optimization" describes how to optimize the system to gain better
performance and precision.
This section must be performed if an optimization of the system is needed.
The section can be carried out in PDM or in S7.
● The section "Operation" describes how to prepare the system for operation.
This section considers the parameters used in cyclic communication of the PLC program
(i.e. process variable and service information).

Any claims resulting from the use of the demo-software are excluded.
9.2.1 Step 1: Reading parameters into DB17 (DB_FLOW_PARA)
Prior to any parameterization it is necessary to read all parameters from the SIFLOW module
into DB_FLOW_PARA as DB_FLOW_PARA only contains default data and not sensor-specific
data. Sensor-specific data are stored in the SENSORPROM situated in the back of the
SIFLOW module.
Read all parameters from SIFLOW
1. Copy index of "S7 Prog_Step1->Blocks" folder into "S7 Prog_Actual->Blocks" folder and
download to the PLC.
2. Prepare a program as shown below.

Step 1: Read all parameters from SIFLOW (CMD_IN = 649)
When the bit "RD_ALL" is set, SIFL_FC initiates reading of all data from the SIFLOW FC070
module and stores them in the DB number addressed at DB_PARA. In this case DB17, also
named DB_FLOW_PARA.

1. Open the variable table "STEP1" and set bit "RD_ALL" to true to read all parameters from
SIFLOW to DB17 (DB_FLOW_PARA).
Now all parameters are updated from the SIFLOW FC070 to DB_FLOW_PARA.
2. Make sure the sensor serial number parameter in the variable table matches the second
part of the serial number written on the sensor label (e.g. 7ME410 125803N386)
Figure 9-4 Step 1
9.2.2 Step 2: Setting basic parameters
In any application the basic parameters to be defined are:
● Measurement range of the application (min - max)
● Measurement unit.
Note
Units and ranges in the Getting Started example
Measurement units are kg/h (values can be found in Appendix B (Page 195).
Upper value for MASSFLOW_MAX is 250 kg/h. FC300 DN4 is default 150 kg/h.
Lower value for MASSFLOW_MIN is 0 kg/h. FC300 DN4 is default 0 kg/h.
Changing settings
1. Copy index of "S7 Prog_Step2->Blocks" folder to "S7 Prog_Actual->Blocks" folder (override
the existing blocks) and download to the PLC.
2. Prepare a program as shown below.
Step 2: Write basic settings to SIFLOW (CMD_IN = 699)
This network prepares the settings to be sent to SIFLOW.
Units and upper and lower values for MASSFLOW are changed.
Units are located in DR 2 and upper/lower values in DR 3.

9.2 Step-by-step guide to commissioning with S7
SIFLOW FC070 with SIMATIC S7
Operating Instructions, 05/2012, A5E02254228-04 87
Thus, command i_CMD_INPUT=699, which writes all data records from DR 2 to DR 12, is used.
Alternatively, data records can be written separately:
DR 2 => i_CMD_INPUT=402
DR 3 => i_CMD_INPUT=403
A programming sequence must be programmed to handle this, however.
The user must configure the parameters "MASSFLOW_UNIT" , "MASSFLOW_MAX" and
"MASSFLOW_MIN".
When bit "WR_BASIC" is set, SIFL_FC initiates writing of all data from "DB_FLOW_PARA" to
the SIFLOW FC070 module.
Figure 9-5 Step 2: Write basic settings to SIFLOW (CMD_IN = 699)
1. Open the variable table "STEP2" and set the parameters "MASSFLOW_UNIT",
"MASSFLOW_MAX" and "MASSFLOW_MIN" and modify variables (i.e. update DB17 with
these values).
2. Set bit "WR_BASIC" to true to write all parameters from DB17 (DB_FLOW_PARA) to the
SIFLOW module. DB_FLOW_PARA.s_Units.b_Massflow_unit,
DB_FLOW_PARA.s_BasicSettings.r_Massflow_max and
DB_FLOW_PARA.s_BasicSettings.r_Massflow_min are now updated in the variable table.

9.2.3 Step 3: System optimization
The flowmeter system is optimized through a zero point adjustment.
Performing a zero point adjustment
1. Install shut-off devices in the pipeline. If possible, both upstream and downstream of the
sensor. Otherwise:
- in horizontal installations at the outlet
- in vertical installations at the inlet
2. Pump liquid at max. flow through the sensor (min. 2 min) in order to avoid air in the liquid.
3. Stop the flow while pumping by shutting off the outlet valve and then the inlet valve. Wait
min. 1 min. In this way there will be zero flow but the liquid remains pressurized within the
sensor, hindering de-gassing of the liquid, i.e. the release of air or other gas from the liquid.
Note
The flow must be completely stopped and the sensor completely filled with liquid.
4. Copy index of "S7 Prog_Step3->Blocks" folder into "S7 Prog_Actual->Blocks" folder and
download to the PLC.
5. Prepare a program as shown below.
Step 3.1: Perform zero point adjustment (CMD_IN = 18)
When "CMD_ZERO_POINT" is set, the zero point adjustment starts.
The zero point adjustment will run for 30 seconds if this setting has not been changed.
As long as the zero point adjustment is running, bit 9 in d_SC_STATUS on SIFL_FC is TRUE
(d_SC_STATUS counts bits 0 ... 31)

1. Open the variable table "STEP3" and set bit "CMD_ZERO_POINT" to true to start the zero
point adjustment.
2. View "ZERO_ADJUST_IN_PROGRESS" bit in the variable table and wait until it gets low.
This bit goes high when starting the zero point adjustment and low again when zero point
adjustment is completed.
3. Set bit "RD_ALL" to true to read all parameters from SIFLOW module to DB17
(DB_FLOW_PARA).
4. Verify the zero sigma value (DB_FLOW_PARA.s_ServiceInformation.r_Zero_sigma) and
zero offset value (DB_FLOW_PARA.s_ServiceInformation.r_Zero_offset_value). These
values should not exceed their limits
(DB_FLOW_PARA.s_BasicSettings.r_Zero_sigma_limit and
DB_FLOW_PARA.s_BasicSettings.r_Zero_offset_limit).
Figure 9-8 Step 3
CAUTION
In case of system failures (SF led = red on the SIFLOW module), refer to section
"Diagnosing and troubleshooting" (Page 171).
Make sure that there is no failure or unacknowledged error before continuing with the next
steps.

9.2.4 Step 4: System ready for operation
The system is now ready for normal operation. Process values can be fetched by:
1. Cyclic reading of process values from VAR_1_VAL or VAR_2_VAL (free of choice).
2. Reading all process values by means of CMD_IN, reading DR30 which comprises all
available process values.

Approach 1 – cyclic reading of process values
VAR_1_VAL and VAR_2_VAL will show MASSFLOW and VOLUMEFLOW in default
configuration. For every call of FB95 (SIFL_FC) these values will be updated, thus performing
a cyclic reading of the two most important values for a particular application.
In order to change the process values shown on VAR1_VAL and VAR2_VAL, new process
value addresses must be used on the parameters VAR1_ADR and VAR2_ADR.

1. Copy index of "S7 Prog_Step4_Approach1->Blocks" folder into "S7 Prog_Actual->Blocks"
folder and download to the PLC.
2. Prepare a program as shown below.
Step 4 - approach 1: New address for VAR1_VAL and VAR2_VAL (CMD_IN = 703 and 704)
This network sets a new process value (two values) to be updated in every cycle.
"NEW_VAR1_ADDR" and "NEW_VAR2_ADDR" are the new addresses of the process values
set by the user. When "SET_VAR_ADR" bit is set, it requires two write commands to change
both values as they have different i_CMD_INPUT values.
Example: If the process values are changed to show density and sensor temperature, the user
must set "NEW_VAR1_ADDR" = 3004 and "NEW_VAR2_ADDR" = 3006.

folder and download to the PLC.
2. Prepare a program as shown below.
Step 4 - approach 2: Read all process values in DR 30 (CMD_IN = 230)
Prepare reading of all process values from SIFLOW.
This network issues the i_CMD_INPUT = 230 which reads all process values from SIFLOW
and stores them in DB17 "DB_FLOW_PARA".

10.6 Installing the SIFLOW CT OCX
Before installing the SIFLOW CT OCX package, ensure that WinCC flexible 2008 SP2 is
installed on the engineering station. The installation will fail if WinCC flexible 2008 SP2 is not
installed on the engineering station.
Before starting the Setup program, close all applications (such as Microsoft Word, etc.), as
Windows must be restarted after the installation of SIFLOW CT OCX so that the OCX can be
completely integrated into the WinCC environment.
The SIFLOW CT OCX package setup consists of two files:
setup.exe The setup frame application
SCOVxxx.msi The windows installer file of the setup (e.g. SCOV01.00.00.00_01.02.msi)
Start the setup program by double-clicking the setup.exe program and follow the installation
steps.
If the setup program detects the installation of an old version of the SIFLOW CT OCX, the old
version will be uninstalled before installation of the new version.
You cannot install an old SIFLOW CT OCX version over a newer version. If you want to do so,
you must manually uninstall the new version prior to installation of the old version.
After finishing the installation of the SIFLOW CT OCX, the target system must be restarted
otherwise the OCX will not be visible in WinCC flexible.
Note
SIFLOW CT OCX registers itself in the system files of the MS Windows operating system.
You cannot delete, move or rename SIFLOW CT OCX files or folders using Microsoft
Windows utilities such as the Explorer or modify SIFLOW CT OCX data in the Microsoft
Windows registry. The control may no longer run properly after such modifications.
10.7 Removing the SIFLOW CT OCX
Use the Microsoft Windows application "Add/Remove Programs" (for example, under MS
Windows XP in the taskbar in …> Settings > Control Panel > Add/Remove Programs) to
remove your software package (for example, "SIFLOW CT OCX V1.0 for WinCC flexible 2008
SP2").
As an alternative, you can use the SIFLOW CT OCX setup program to uninstall a program.

10.13 Limitations
The current version of the SIFLOW CT OCX has the following limitation:
● Panels based on the Windows CE 3.0 platform are currently not supported.
10.14 Configuring and operating the SIFLOW CT OCX
The SIFLOW CT OCX package must be installed on the engineering station for use within
WinCC flexible ES. On the engineering station the device-specific HMI application, including
the SIFLOW CT OCX for displaying calibratable values, must be built for S7-300 automation
systems with integrated SIFLOW FC070 Ex CT module. After that the HMI application including
the device-specific SIFLOW CT OCX must be downloaded to the panel through the WinCC
flexible ES. The calibratable values from the SIFLOW FC070 Ex CT module can then be
displayed on the panel. The supported panels are listed in "Supported devices" (Page 99).
The calibratable values are provided to the OCX within the HMI application through exchanging
data with the S7 application running the SIFLOW FB/DBs in order to handle the communication
with the SIFLOW FC070 Ex CT module, see "Description" (Page 21).
10.14.1 Creating the HMI project
After the SIFLOW CT OCX has been installed on the engineering station, a WinCC flexible
project must be established for the desired HMI panel. This can be accomplished by using the
project wizard within WinCC flexible. To simplify the setup of connections and tags, it is
recommended to integrate the WinCC flexible project with the associated S7 project. Please
refer to documentation of S7 and WinCC flexible for further descriptions.
The following figure shows a WinCC flexible project for a MP277 8" Touch panel and the
appearance of the SIFLOW CT OCX within an HMI screen.

The "Acquisition cycle" should be in the range below 3 seconds, because the communication
timeout controlled by the OCX and the FW on the SIFLOW module is set to a maximum of 3
seconds and will report an error, see "ERROR 1" (Page 101) if it is exceeded.
10.14.4 Setting up tag representing output data for OCX write
The SIFLOW CT OCX communicates to the SIFLOW FC070 CT module by writing to output
data section w_OCX_WRITE_DATA of the DB_FLOW_PARA data record on the PLC. The
SIFLOW FB running on the PLC transfers this output data to the SIFLOW FC070 Ex CT module
by writing the data to Bytes 10 and11 (OCX write data) of the s7_control_signals in the
peripheral interface.
In the "Tags" section within the "Communication" item of WinCC flexible tags used within the
HMI project can be defined. If the WinCC flexible project is integrated with an associated S7
project, the tag can be setup by simply selecting the appropriate PLC variable
"DB_FLOW_PARA.w_OCX_WRITE_DATA" from the drop-down box while inserting a new tag.

Functions 11
11.1 Zero point adjustment
Zero point adjustment function
The zero point adjustment settings of the flowmeter is done by using the parameters in the
following table:
Parameter Label Description
DR3: zero_adjust_time Zero adjust time Duration of zero adjust setting in [s] (for
progress, see DR30 →
zero_adjust_progress) 0 … 65 535 s
DR3: zero_sigma_limit Zero sigma limit Max. zero sigma permitted by automatic
zero adjust setting
DR3: zero_offset_limit Zero offset limit Max. zero offset of automatic zero adjust
DR11: zero_offset_preset_value Zero offset preset value Default settings for the zero adjust
function: Value in mass flow units
Automatic zero point adjustment
The SIFLOW FC070 function module measures and calculates the correct zero value
automatically.
Before zero point adjustment is instigated, the pipe must be full and at an absolute flow rate
of zero. When zero adjust is instigated using the command
CMD_START_AUTO_ZERO_ADJUST, the mass flow values are acquired and totaled for the
configured period (DR3: zero_adjust_time), and an average value is calculated using the
following formula:
Sensor zero value

Operating Instructions, 05/2012, A5E02254228-04 115
The zero point adjustment time DR3: zero_adjust_time determines the duration of the
automatic zero adjustment. The standard value, 30 s, is normally sufficient for a stable zero
measurement.
Note
Extremely small flow quantity
If the flow quantity is extremely small, extremely precise measurement is necessary. In this
case, a long integration time can be selected for improved zero point measurement.
During the zero point adjustment procedure, the status bit
ST_ZERO_ADJUST_IN_PROGRESS is set and the progress of the procedure can be scanned
as a percentage in DR31: zero_adjust_progress.
After completion of the DR3: zero_adjust_time, the standard deviation
DR31: zero_sigma is calculated in accordance with the following formula:

The zero point sigma contains important feedback on the homogeneity of the fluid, e.g. on the
presence of bubbles or particles.
The standard deviation must be within a window related to the determined zero point x.
● When DR31: zero_sigma is greater than the configured limit (DR3: zero_sigma_limit), the
error PE_ZEROADJ_SIGMA_LIMIT is set.
In this case, the user should check that the pipe is full and that the flow rate is absolute
zero. The zero point adjustment should then be repeated.
● When the zero point exceeds the value DR3: zero_offset_limit, the error
PE_ZEROADJ_OFFSET_LIMIT and the system status bit
ST_ZERO_ADJUST_OFFSET_LIMIT_EXCEEDED are set. The status bit
ST_ZERO_ADJUST_OFFSET_LIMIT_EXCEEDED is reset by the next
CMD_START_AUTO_ZERO_ADJUST command.
● When DR31: zero_sigma is less than DR3: zero_sigma_limit, the zero point is valid and is
automatically stored in the DR31: zero_offset_value and in the SENSORPROM as the new
zero point for the sensor. It remains stored in the case of a power failure.
On completion of the zero point adjustment procedure, the status bit
ST_ZERO_ADJUST_IN_PROGRESS is reset and DR30: zero_adjust_progress is set to 0.
During the zero point adjustment procedure, no parameter changes are accepted.
Manual zero point adjustment
After a CMD_ZERO_OFFSET_VALUE_PRESET, the DR11: zero_offset_preset_value is
stored in the DR31: zero_offset_value and in the SENSORPROM as the new zero point for

11.2 Low flow cut-off
In certain applications, no flow signals under a certain flow level are desired (low-flow cut-off).
A lower limit between 0 and 10 % can be set for using the process value by the output and the
totalizer by means of the parameter DR3: low_flow_cut_off.
This percentage is related to the maximum setting of the mass flow DR3: massflow_max.
The low-flow cut-off function influences the following process values:
● Mass flow
● Volume flow
● Fraction A flow
● Fraction B flow
● Totalizer 1
● Totalizer 2 / batch

11.3 Empty pipe monitoring
"Empty pipe detection" can be set using parameter DR3: empty_pipe_detection_on_off. This
function is used for detecting an empty pipe.
A lower limit for the density of the fluid can be set using parameter
DR3: empty_pipe_limit. When the value falls below this, the process error PE_EMPTY_PIPE
is reported.
No hysteresis is processed for this limit.

11.4 Noise filter
Noise filter function
The SIFLOW FC070 module carries out the signal processing in the Coriolis ASIC using a
patented FFT algorithm (FFT = Fast Fourier Transformation). Sensor signals that are prone
to interference can be filtered using this technology. If, for example, a strongly pulsating flow,
changing pump frequencies or large pressure variations occur at the sensor, this can in certain
cases result in noise voltages in the sensor signals and therefore measurement errors.
Noise filter settings
These measurement errors can be reduced by increasing the filtering parameter DR3:
noise_filter. Setting 5 represents the maximum possible filtering level and setting 1 is the
minimum possible filtering level.
● 1 = min.
● 2
● 3
● 4
● 5 = max.

The min. / max. values in DR3 are primarily used for the scaling of the process values. The
range between min. and max. is thereby related to the display range of the ASIC process value,
whereby absolute values are generated.
Note
The parameter DR3: massflow_max also serves as the upper monitoring limit for the value
DR30: massflow. Monitoring is carried out in the ASIC. If the maximum value is exceeded,
the ASIC sets the STATUS_WL_QMAX_OVERLOAD bit in the ASIC status; this results in
the error PE_FLOW_SATURATED.
Note
The parameters DR3: sensor_temperature_max and DR3: sensor_temperature_min are also
used as monitoring limits for the value from DR30: sensor temperature. Monitoring is carried
out in the ASIC. If a limit is exceeded, the ASIC sets the STATUS_WL_TEMP_ERROR bit in
the ASIC status; this then leads to the error PE_TEMP_MAX or PE_TEMP_MIN.
Unit conversion
The units at the external SIMATIC and MODBUS communications interfaces can be set for
every process value using the following parameters:
Process value Unit ID (default = SI)
massflow_unit 0...255 (SI = kg/s)
volumeflow_unit 0...255 (SI = m3/s)
density_unit 0...255 (SI = kg/s or m3/s)
temperature_unit 0...255 (SI = K)
totalizer_1_unit 0...255 (SI = kg or m3)
totalizer_2_unit 0...255 (SI = kg or m3)
density_unit 0...255 (SI = kg/m3)
batch_unit 0...255 (SI = kg or m3)
pulse_amount_unit 0...255 (SI = kg or m3)
The values affected by the unit are converted at both interfaces from the external unit to SI
unit on receiving and are converted from the SI unit to the external unit on sending.
The conversion factors are stored in a table of constants in the firmware. The units tables are
documented in the appendix.
If the SI unit is also configured at the external interfaces, a conversion is not carried out.
Note
The SI unit is always used within the function module (ASIC, SENSORPROM, etc.).

11.6 Limit value monitoring
Limit monitoring function (4 limits)
A total of 4 limits can be assigned in any order for the selectable process values
DR12: limit x_selection.
1, 2, 3 or all 4 limits can be assigned to a process value to be monitored.
Example
4 limits for mass flow (2 low, 2 high)
● 2 limits for mass flow (1 low, 1 high)
2 limits for volume flow (1 low, 1 high)
● 1 limit for mass flow (1 high)
1 limit for volume flow (1 high)
1 limit for density (1 low)
1 limit for sensor temperature (1 high)
The limit DR12: limit x_setpoint and the hysteresis DR12: limit x_hysteresis are configured as
a percentage of the maximum value of the selected process value (e.g. for mass flow:
DR3: massflow_max).
The parameter DR12: limit x_direction defines the type of the limit. There are low limits and
high limits.

● In case of a low limit, the corresponding limit bit ST_LIMIT_x in the system status is set
when the process value undershoots the setpoint. The status bit is reset if the process value
exceeds the setpoint plus hysteresis.
● In case of a high limit, the corresponding limit bit ST_LIMIT_x in the system status is set
when the process value overshoots the setpoint. The status bit is reset if the process value
undershoots the setpoint minus hysteresis.

The only exception is when a totalizer is selected for limit_x_selection. In this case the

Tripping of an S7 process interrupt for a set or reset limit bit can be activated in the status
using DR7: s7_pral x_assignment. This ensures that a fast response to a limit overshoot occurs
in the PLC program.

11.7 Simulation
Simulation function
Various values in the system can be set to configured simulation values by DR10:
simulation_enable. Following options are available:
● Simulate mass flow value
● Simulate volume flow value
● Simulate density value
● Simulate sensor temperature

● Simulate fraction A percent
● Simulate output 1
● Simulate output 1 frequency
● Simulate output 2
● Simulate output 2 frequency
● Simulate input value
● Simulate error
As soon as at least one value is simulated (i.e. at least one bit in DR10: simulation_enable) is
set, the yellow SIM LED lights up and the system status bit ST_SIMULATION_ACTIVE is set.
The simulation can be activated at any time over SIMATIC or MODBUS.
The other interface in each case is informed about the activation by means of the status
ST_SIMULATION_ACTIVE.
The currently simulated values can be read out in DR10: simulation_enable.
Possible values
Possible values for DR10: simulation_enable:
SIMULATION_OFF (WORD) 0x0000
SIMULATION_MASSFLOW_ENABLE (WORD) 0x0001
SIMULATION_VOLUMEFLOW_ENABLE (WORD) 0x0002
SIMULATION_DENSITY_ENABLE (WORD) 0x0004

SIMULATION_FRACTION_A_PERCENT_ENABLE (WORD) 0x0040
SIMULATION_OUTPUT_1_ENABLE (WORD) 0x0080
SIMULATION_OUTPUT_2_ENABLE (WORD) 0x0100
SIMULATION_INPUT_ENABLE (WORD) 0x0200
SIMULATION_ERROR_NO_ENABLE (WORD) 0x0400
For mass flow, volume flow, density and sensor temperature, the simulated value has to be
entered in the correct units.
Example
Simulating mass flow = 1 kg/s:
● DR10: simulation_enable = 0x0001
● DR10: simulation_value_massflow = 1.0
● DR2: massflow_unit = 0 (SI, kg/s)
For simulating percent_fraction_a, the percentage value has to be entered, e g. for simulating
a fraction flow A of 35%:
Functions
11.7 Simulation

● DR10: simulation_enable = 0x0040
● DR10: simulation_value_percent_fraction_ a = 35
The result for fraction A is 35% of the measured mass flow (if mass flow is selected for the
fraction).
The result for fraction B is automatically calculated as 65% (100% minus 35%) of the measured
mass flow (if mass flow is selected for the fraction).
Output simulation
Both outputs can be simulated via the force function of the outputs in the ASIC.
Possible values for DR10: simulation_value_output_1 or 2:
Output low 0
Output high 1
Output frequency 2
Possible values for DR10: simulation_value_output_1(_2)_frequency:
● 0…12500
Activation of the simulation is rejected if a batch procedure is currently running on an output.
This applies to both outputs if a two-stage batch or quadrature is running. The activation must
then be repeated at a later time.
Only the operation of the outputs via the SIMATIC IO area s7_control_signals ->digital_output
is accepted as an emergency stop circuit.
Input simulation
The level of the input is not read from the HW input but is simulated in the firmware. Edge/level
evaluation at hardware input DR6: input_inversion and the following firmware filtering
DR6: input_filter_time are omitted. The SF reaction DR6: digital_input_sf_reaction is not taken
into account either. The function set in the configuration DR6: digital_input_function is then
executed.
Error simulation
If the simulation of an error is activated by DR10: simulation_enable, the error entered under
DR10: simulation_value_error_no is simulated as a set error. If simulation is deactivated with
DR10: simulation_enable, the error is reported as reset.
Range: only SE and PE errors, no HE errors.

11.8 Output
11.8.1 Digital output
Two digital outputs
The Coriolis ASIC controls 2 digital outputs. Seven modes can be set for outputs in the Coriolis
ASIC:
● Pulse (only output 1)
● Frequency (only output 1)
● Phase shift pulse (outputs 1 + 2) 90°
● Phase shift pulse (outputs 1 + 2) 180°
● Phase shift frequency (outputs 1 + 2) 90°
● Phase shift frequency (outputs 1 + 2) 180°
● Two-stage batch (outputs 1 + 2)
● Batch (only output 1)
Output 1
Output 1 can be used for the variable:
● Process value as frequency-proportional signal
● Process value as quantity-dependent pulse repetition
● Quantity-dependent valve control (batch)
Output 2
Output 2 is not an independent output with the same functions as output 1, but can be used
as an additional output for the following functions.
● Two-stage batch
● Phase shift pulse (90° or 180°)
● Phase shift frequency (90° or 180°)
Control of the outputs
Both outputs are low at the ASIC during a reset. The digital outputs controlled by the ASIC can
be overwritten by the firmware and directly controlled over the port pins of the controller. This
is necessary in the following cases:
● during startup until the system (sensor) is stable (approx. 40 s)
● in the phase of power-down

● when the firmware has to control the outputs directly (e.g. OD signal)
● when the user wants to control the outputs directly from SIMATIC P-bus
Parameters are used to specify how the outputs should be set in the case of a set OD signal
(S7 CPU STOP) or on failure of the P-bus 5 V power supply.
Additionally, the reaction with respect to the outputs in the case of a set system fault (SF) can
be configured (DR5: digital_output_sf_reaction).
The possibility of direct control is not used for the simulation of the output; the force function
of the ASIC is used here.
In normal operation, the condition of both outputs is shown on LEDs DO1 and DO2.
11.8.2 Pulse output
Pulse output function
The pulse output function supplies a pulse at output 1 with the configurable pulse width
DR5: pulse_width and a pulse spacing that is proportional to the selected process value
DR5: pulse_value_selection.
The pulse is always output according to the flow of a configurable delta quantity
DR5: pulse_mass_or_volume_amount.

DR5: pulse_width = 1 ms
DR30: massflow = 1 kg/s (constant)
Result:
● Pulse length = 100 ms
● Output frequency = 10 pulses per second with a pulse width of 1 ms
The pulse frequency generator for the output in the ASIC can supply a frequency between 0.1
Hz and 12 kHz with a resolution of 0.06 Hz.
DR5: pulse_direction can be used to set whether the pulse output should only output positive
(upward) or bidirectional (upward/downward) process values.

11.8.3 Frequency output
Frequency output function
The frequency output function supplies a frequency (50% pulse/pause ratio) at output 1 that
is proportional to the selected process value DR5: frequency_value_selection.
The pulse frequency generator for the output in the ASIC can supply a frequency between 0.1
Hz and 12 kHz with a resolution of 0.06 Hz.
The following maximum frequencies are selectable by means of parameterization:
● 0 = 10 kHz
● 1 = 5 kHz
● 2 = 1 kHz
● 3 = 500 Hz
The configured frequency DR5: frequency_max corresponds to 100%.

Result:
● Output frequency = 500 Hz with 50% pulse/pause ratio

11.8.4 Phase shift output
Phase shift function (pulse or frequency at outputs 1 and 2)
Via the phase shift function, the two outputs can also display whether there is a forward or
backward flow.
The phase shift function can be activated in pulse and frequency modes.
● In phase shift pulse mode, output 1 behaves just as in normal pulse mode. Output 2
generates a pulse with the same frequency as output 1, but shifted by half a pulse length.
For a positive process value, output 2 is delayed by half a pulse length with reference to
output 1; for a negative process value, output 2 leads by half a pulse length.
● In phase shift frequency mode, output 1 behaves just as in normal frequency mode. Output
2 generates the same frequency as output 1, but shifted by a quarter of the period. For a
positive process value, output 2 is delayed by a quarter period with reference to output 1;
for a negative process value, output 2 leads by a quarter period.
11.8.5 Batch output
Batch function (dosing)
The digital output can be set for the batch function by setting the parameter
DR5: digital_output_function. The batch function is used for measuring the quantity of gas or
fluid. Thereby e.g. a valve is opened and closed via the digital output.
Measuring of an outflowing quantity is started by the CMD_BATCH_START command which
sets the output to High which opens the valve.
When a preset mass or volume DR11: batch_quantity is reached, the valve is closed via the
digital output (= 0). The batch procedure is complete. A new batch procedure can be started
150 ms after the start of the preceding batch procedure. There must be a wait time of at least
50 ms between the batch stop and the new batch start.
The process value that serves as input for the batch function is selected via
DR5: batch_value_selection:
● 1 = mass flow
● 2 = fraction A
● 3 = fraction B
● 4 = volume flow
The batch output is reset to 0 if the frequency pulse generator is reset.
The batch compensation function (offset) allows a fixed amount DR11: batch_compensation
to be added/subtracted to compensate for valve delays.
An additional compensation value is the time constant DR11: batch_lead_constant which is
loaded when the output function for batch is reconfigured. The lead constant (time constant)
DR11: batch_lead_constant is handled in the unit [s].
This compensation takes into account flow variations.
Functions
11.8 Output
SIFLOW FC070 with SIMATIC S7
128 Operating Instructions, 05/2012, A5E02254228-04
Example:
Setting the parameter batch_lead_constant
● Set all compensations to zero (DR11: batch_compensation and
DR11: batch_lead_constant).
● Enter the desired amount DR11: batch_quantity (M-wanted e.g. 25 kg), and start the batch
process.
● Observe the flow, reading the flow DR30: massflow just before the batch stop (Q-end, e.g.
5000 kg/h).
● Note the amount that the totalizer DR30: totalizer_2_batch indicates and read the amount
after the totalizer stops (M-real e.g. 25.5 kg).
● Calculate the lead constant as:
–LeadConst = (M-real - M-wanted) / Q-end.
Note
LeadConst is specified in seconds
For the example, this will result in:
LeadConst = (25.5 kg - 25 kg) / (5000 kg/h) = 0.0001 h = 0.36 seconds.
● Enter this value as lead constant. This is a good starting point which only requires small
adjustments to be made. SIFLOW FC070 is now to fill 25 kg, even if the flow changes. (If
the valve closing time also changes, this is not the case! The lead constant can only
compensate real changes in flow.)
Batch timeout monitoring
The batch timeout monitoring checks whether the batch procedure has been terminated within
the set time DR5: batch_time_max. If this is not the case, an error PE_BATCH_TIMEOUT is
generated. The batch timeout monitoring can be switched on and off by means of the parameter
DR5: batch_time_error_on_off.
Batch overrun monitoring
The batch overrun monitoring checks that the flow quantity through the valves in the closed
state does not exceed a preset quantity DR5: batch_overrun_error_quantity. This function can
therefore detect a valve malfunction (non-closure) caused by a blockage, wear, etc. If the
quantity is exceeded, the error PE_BATCH_OVERRUN is signaled. The batch overrun
monitoring can be switched on and off by means of the parameter DR5: batch_overrun_on_off.

Batch counter
The batch counter indicates how the batch quantity DR11: batch_quantity changes in the
course of a batch procedure. Totalizer 2 serves as a batch counter
DR30: totalizer_2_batch.
● If DR5: batch_counter_up_down = up is selected, the batch counter counts up from 0 up to
the selected quantity DR11: batch_quantity.
● If DR5: batch_counter_up_down = down is selected, the batch counter counts down from
DR11: batch_quantity to 0.
Batch commands
A batch procedure can be started, halted, continued or stopped completely using the
appropriate commands
● CMD_BATCH_START
● CMD_BATCH_HOLD
● CMD_BATCH_CONTINUE
● CMD_BATCH_STOP
The current state of the batch procedure can be seen in the system status window.

11.8.6 Two-stage batch output
Two-stage batch function (level at outputs 1 + 2)
The two-stage batch function is used for implementing coarse/fine metering of the quantity to
be filled. Both digital outputs are required for this.
On starting the batch procedure, both outputs are first activated together (high). This ensures
that the amount is filled quickly (2 valves). This is indicated in the system status by the bit
ST_BATCHING.
After DR11: batch_two_stage_level in % of DR11: batch_quantity has been reached, output 2
is switched off by the ASIC. This is indicated by the system status bit
ST_BATCH_TWO_STAGE_REACHED.
The remaining amount to be filled is controlled by the ASIC using fine metering, and only via
output 1. When 100% of the quantity to be filled DR11: batch_quantity has been reached,
output 1 is also switched off and both status bits ST_BATCHING and
ST_BATCH_TWO_STAGE_REACHED are reset to indicate that the batch procedure has been
completed.
For the two-stage batch function, both output paths in the ASIC are set identically with the
exception of the fill quantity. The different amounts result in the different switch-off times for
the two outputs.
No parameters that influence the batch procedure are accepted while the batch is being
processed.

11.8.7 Freezing and forcing outputs
Force function
Following the command CMD_FORCE_OUTPUT_ON, both outputs are switched to a
frequency specified by DR6: force_frequency_output_value and DR5: frequency_max. The set
output frequency is force_frequency_output_value * frequency_max. A
CMD_FORCE_OUTPUT_OFF command switches back to the frequency calculated from the
measured value.
Freeze function
Following a CMD_FREEZE_OUTPUT_ON command, the actual output frequencies on both
outputs are frozen to ensure that they cannot be changed by the measured value. A
CMD_FREEZE_OUTPUT_OFF command switches back to the frequency calculated from the
measured value.
Both commands (force and freeze) will only be executed when the outputs are parameterized
for frequency.
11.9 Input
11.9.1 Digital input
The digital input is an interrupt input for the controller. This ensures the shortest response time
possible.
The configured firmware filter time DR6: input_filter_time is started after detecting the
configured edge transition. The edge transition from Low to High is the active edge; when
inversion is configured with DR6: input_inversion = on, the edge transition from High to Low
is significant. The event is only accepted if the input level remains unchanged during the filter
time. This is also indicated by the DI1 LED. The level of the input signal is also indicated in the
system status bit ST_DIGITAL_INPUT_STATE.

11.10 Process Information
11.10.1 Process values
Process information is information that can only be read. It can be read out of the function
module via SIMATIC and MODBUS.
The separate items of process information are collected for SIMATIC in data record DR30 and
are stored individually for MODBUS under the respective MODBUS address.
Process information is generated in the SIFLOW function module from the ASIC process
values and the associated status and is updated in the acquisition cycle of the Coriolis ASIC
(approx. 33 ms).
The process values are:
● System status
● Mass flow
● Volume flow
● Density
● Sensor temperature
● Fraction A flow
● Fraction B flow
● Percent fraction A
● Totalizer 1
● Totalizer 2 batch
Functions
11.10 Process Information
SIFLOW FC070 with SIMATIC S7
Operating Instructions, 05/2012, A5E02254228-04 133
Process value update cycle
The data are made available as soon as possible. The update cycle is synchronous with the
ASIC update cycle. Triggered by the new data, reading from the ASIC and processing of
process values are performed every 33 ms.
The cyclic arrival of the new data (33 ms) is monitored by the firmware. When data are not
received in two cycles, an ASIC error SE_ASIC_WATCHDOG is generated.
Before the transfer buffer is saved for the SIMATIC and MODBUS interface, the values are
converted to the configured unit (national dimension unit that is used outside the SIFLOW
function module).
11.10.2 Fraction
The fraction is determined as part of a mixture. This mixture, e.g. of a fluid, comprises two
components A + B which can be determined individually.
If the flowmeter is ordered with a specific fraction, e.g.°Brix, it can determine the percentage
concentration percent_fraction_A of sugar in a solution of water (B) + sugar (A).
Calculating the fraction
percent_fraction_A is a percentage calculated using the following formula:
percent_fraction_A [%] = fraction_offset + fraction_factor * %fraction
where:
% fraction = Intercept
+ x1 * T + x2 * T2
+ (x3 + x4 * T + x5 * T2) * ρ
+ (x6 + x7 * T + x8 * T2) * ρ2
+ (x9 + x10 * T + x11 * T2) * ρ3
● T = FractionTemp
● ρ = FractionDens
● xn = DR33: fraction_calibration_X0 … X11
● Intercept = x0
The DR9: fraction_factor is factory-set to 1.000 and the DR9: fraction_offset is set to 0. If you
want to increase the percentage concentration in the flowmeter by 0.5 %, you must increase
the DR9: fraction_factor to 1.005. Following this change, the flowmeter indicates an increase
in concentration of 0.5%.
One of two input values can be used when calculating the fraction: mass flow or volume flow.
The DR33: fraction_value_selection parameter is factory-set in the SENSORPROM and can
only be scanned by the module firmware.
The fraction flow values are calculated according to the following formula:

Mass flow:
fraction_A_flow = massflow * percent_fraction_A
fraction_B_flow = massflow * (1 - percent_fraction_A)
Volume flow:
fraction_A_flow = volumeflow * percent_fraction_A
fraction_B_flow = volumeflow * (1 - percent_fraction_A)

DR9 Sensor properties (R/W) (Page 218)
11.10.3 Totalizer
SIFLOW FC070 has 2 independent totalizers that can be used for the summation of mass flow,
fraction A, fraction B or volume flow.
You can use parameters to set which value is to be totalized (totalizer_x_selection) as well as
the flow direction for the count (totalizer_x_direction).
The totalizers have a 64-bit counter in the firmware.
Note
Changing Totalizer x selection while the totalizer is running may lead to an undefined totalizer
value shown as "NaN" (Not a Number). Therefore, it is recommended to hold and reset (see
below) totalizer x before changing this parameter.
Totalizer values
The totalizer values are available as DOUBLE values and as FLOAT/REAL values. Both types
can be read using the Modbus address. Only the REAL value DR30: totalizer_1 or
DR30: totalizer_2_batch is saved in DR30.
If there is a group error (SF), a decision is made via the totalizer_x_fail_mode parameter as to
which value the totalizer should process. The firmware totalizer (64-bit) always continues to
execute during an SF error. The totalizer value (48-bit) from the ASIC, which is most probably
invalid, is no longer used as delta; a fixed value is used instead. This value can be the last
valid value read out from the ASIC before the error, or it can be zero.

Reset and preset of totalizers
The totalizers can be halted using the command CMD_TOTALIZER_x_HOLD. They are
restarted by CMD_TOTALIZER_x_CONTINUE.
With the totalizer commands, the two totalizers can be handled individually or together.
When the function module starts up, the totalizer is halted initially until the sensor has
completed its transient phase (approx. 40 s). The function module then starts, and the 64-bit
totalizer values are stored in the FRAM before the restart.

Operating Instructions, 05/2012, A5E02254228-04 137
11.11 Date and time
Date and time
An absolute time in 8-byte SIMATIC format is kept in the SIFLOW FC070 function module
(date and time).
BCD format:
● [0] year
● [1] month
● [2] day
● [3] hour
● [4] minute
● [5] seconds
● [6] milliseconds (100's and 10's positions)
● [7] milliseconds (1's position) + day of week (in lower 4 bits)
During startup, the date and time are set to the last value before power down (this is saved in
the FRAM). This results in a jump in time for incoming messages that occur before the first
positions for date and time (with reference to the actual time). However, the correct order is
ensured for sorting the time of date-stamped information.
Messages are written into the error history of the diagnostics and firmware which allows the
user to determine the time of power failure and the time setting.
The date and time can be set by the SIMATIC via DR8: date_and_time. The time can also be
set by passing on the variables in the SIMATIC IO control signal. The variables are passed on
here in the same manner as for MODBUS with a MODBUS address and a 4-byte value.
If the SIFLOW FC070 function module does not have a valid value for
DR8: date_and_time, the ST_DATE_AND_TIME_NOT_SYNC bit is set in the system status.
The user can start transfer of the current SIMATIC CPU time using this information. The
ST_DATE_AND_TIME_NOT_SYNC bit is reset when DR8: date_and_time has been newly
received.
The date and time should be reset by the user program each time the SIFLOW FC070 function
module is restarted and reset at regular intervals to synchronize it with the date and time of
the SIMATIC CPU. In this manner, synchronization between the time stamps of the CPU and
the SIFLOW function module can be accurate to within seconds.
Operating time counter
The SIFLOW function module has two operating time counters:
● Total operating time (DR31: operating_time_total)
● Operating time since the last power up (DR31: operating_time_powerup)
Both are kept as service information in DR31 and are updated every hour. The total operation
time is kept powerfail-safe in the FRAM.

11.12 Service information
Service information is information that can only be read. It can be read out of the function
module via SIMATIC and MODBUS.
The separate items of service information are collected for SIMATIC in data record DR31 and
are stored individually for MODBUS under the respective MODBUS address.
Service information provides information on the condition of the sensor and the transmitter. It
is updated in the SIFLOW function module every 330 ms (3 Hz).
The service data are:
● Date and time
● Operating time total
● Operating time since power-up
● Driver signal
● Pick-up 1 amplitude
● Pick-up 2 amplitude
● Sensor frequency
● Transmitter temperature
● SENSORPROM installed
● Zero offset value
● Zero adjust progress
● Zero sigma
● Batch cycle counter
Detection of inside temperature of enclosure
The SIFLOW FC070 function module contains a circuit for measuring the internal enclosure
temperature.
The circuit guarantees a temperature value with a tolerance of ±2°C.
The value is detected and indicated in DR31: transmitter_temperature.
If the temperature exceeds 85°C, the error SE_TRANSMITTER_TEMPERATURE is
generated. If the temperature falls below 80°C, the error is reported as reset.
No further temperature compensation processes are derived from this.

function module via SIMATIC and MODBUS.
The separate items of MODBUS service information are collected for SIMATIC in data record
DR36 and are stored individually for MODBUS under the respective MODBUS address.
The MODBUS service information is information regarding the status of the MODBUS
connection and the MODBUS slave.

Alarm, error, and system messages 12
12.1 Messages and diagnostics
Message types
The messages of the SIFLOW FC070 are divided into two types:
1. Asynchronous messages
2. Synchronous messages
Asynchronous messages
Asynchronous messages can be generated spontaneously at any time by an unexpected
event. Such events include internal and external hardware faults (status messages) and
technology messages which can occur spontaneously during a measurement.
Types of error belonging to the asynchronous messages:
● Sensor errors (SE) (Page 152) indicating faults on the function module, sensor,
SENSORPROM or cabling (internal faults)
● Process errors (PE) (Page 152) for faults in the process (external faults)
Synchronous messages
The synchronous messages are always the result of a user activity. These include:
● Data errors if a plausibility error has been detected in a data package which was sent to
the function module, and receipt of the package has been rejected by the function module.
● Operating errors if the function module in its current operating state cannot execute the
sent command.
Types of errors belonging to the synchronous messages:
SIFLOW FC070 with SIMATIC S7
Operating Instructions, 05/2012, A5E02254228-04 141
● Data and operating errors (HE) (Page 156).
Note
System status information
System status information is not a message. The status displays describe the status of
the function module during normal operation, and can be monitored or evaluated at any
time.
See also: System status information (Page 162).
Message paths
The messages of the SIFLOW FC070 reach the user via different paths. It is necessary when
configuring to select the correct message path for passing on and processing.
The messages are processed for two basic purposes:
● For display on an operator panel
● For linking in the control software in order to trigger a certain process response.
The following message paths can be selected:
● Output via the signal outputs of the function block
● Diagnostic interrupts in SIMATIC CPU with evaluation by the OB82
● Process alarms in the SIMATIC CPU with evaluation in the process alarm OBs
● Output of message buffer to SIMATIC PDM
Detection and processing of messages
There are four different ways of detecting and processing messages:
●Function block
All messages of the SIFLOW FC070 can be detected completely using the S7 FB SIFL_FC
(FB95), and processed in the PLC. By means of the output variable FB_ERR, errors during
processing of the respective FB are signaled in addition.
●Diagnostic interrupts
The diagnostic interrupts can be used to detect status messages (hardware faults) in the
SIMATIC CPU.
– You can display the cause of the error in the module diagnostics in S7 (see "Hardware
diagnostics" in the S7 online help).
– You can also read out the diagnostics messages using SFCs in the user program.

status information.
– You can display the cause of the error in the module diagnostics in S7 (see "Hardware
diagnostics" in the S7 online help).
– You can also read out the diagnostics messages using SFCs in the user program.
●Output to SIMATIC PDM
In SIMATIC PDM, you can display an error report and a list of currently present errors in
the menu "Error Logbook".
12.2 Interrupt behaviour
Introduction
This section describes the interrupt behavior of the SIFLOW FC070. There are basically two
different types of interrupt:
● Diagnostics interrupt
● Process interrupt
For detailed information on the OBs and SFCs mentioned below, refer to the S7 online help.
Enabling interrupts
The interrupts are preset, but are disabled until programmed accordingly. You program the
enabling of interrupts by double clicking the corresponding function module in HW-Config or
by marking it and selecting the Basic parameters tab in the Object properties.
Diagnostics interrupt
When diagnostics interrupts are enabled, incoming error events (initial occurrence) and
outgoing error events (error is cleared) are reported by means of an interrupt.
The CPU interrupts execution of the user program and runs the diagnostics interrupt block
OB82.
In the user program, you can call SFC 51 or SFC 59 in OB82 to obtain more detailed diagnostics
information from the module.
The diagnostics information is consistent until such time as OB82 is exited. When OB82 is
exited, the diagnostics interrupt is acknowledged on the module.
Reading diagnostics messages
You can read out the first 4 bytes of the diagnostics data record 1 using the variable
OB82_MDL_DEFECT in the user program. The remaining bytes (or also all of them) can be
read using SFC51 "RDSYSST" (reading out an SZL parts list). Do not use the system function
"Read data record", if at all possible, since inconsistencies may occur for the interrupt.
You can display the cause of the error in the module diagnostics in S7 (see S7 online help).

12.2 Interrupt behaviour
SIFLOW FC070 with SIMATIC S7
Operating Instructions, 05/2012, A5E02254228-04 143
Diagnostics message using the SF LED
The function module indicates faults via its SF LED (group fault LED). The SF LED lights up
as soon as a diagnostics message has been triggered by the function module. It is extinguished
when all faults have been eliminated.
The SF LED also lights up to indicate external errors (short-circuit at the encoder supply),
regardless of the CPU operating state (at POWER ON.)
Process interrupt
The SIFLOW FC070 can manage 8 process interrupt events. A certain signal can be assigned
to each process interrupt event through appropriate parameterization. The signal can be
assigned as an incoming HE (operating and data errors), an incoming/outgoing PE / SE
(process/sensor errors) or an incoming/outgoing system status bit.
The parameter setting can be changed at any time (in the RUN state using the user program).
Pending process interrupts trigger process interrupt processing in the CPU (OB 40). The CPU
interrupts the execution of the user program or the priority classes with low priority.
In the user program of the process interrupt OB (OB 40) you can specify how the programmable
controller is to respond to a change in edge. The module acknowledges the process interrupt
when the program exits the process interrupt OB.
The module can store 8 interrupts in intermediate memory. If no run levels of a higher priority
class are pending processing, the CPU processes the buffered interrupts (of all modules) in
the order of their occurrence.
Process interrupt lost
A "Process interrupt lost" diagnostics interrupt is generated if a successive interrupt occurs
before the CPU has processed the previously buffered interrupt.
The CPU does not register any further interrupts unless it has completed processing of the
stacked interrupts.
Interrupt-triggering channels
The channel that triggered the process interrupt is entered in the start information of OB 40 in
the OB 40_POINT_ADDR variable.
You can find the diagnostics messages with their possible causes and remedies in the table
"Sensor and process errors" (Page 152) and in the table "Data and operating errors"
(Page 156).

12.3 Diagnostics data
SIFLOW FC070 with SIMATIC S7
144 Operating Instructions, 05/2012, A5E02254228-04
This chapter describes the diagnostics data structure in system data. You must be familiar with
this configuration if you want to evaluate the diagnostics data of the SIFLOW FC070 function
module in the S7 user program.
Note
Evaluation of error OBs (I/O access errors, rack error interrupts, hot swapping interrupts,
diagnostic interrupts, process alarms) is not carried out in the function block SIFL_FC (for
S7), but must be carried out in the standard interrupt OBs (diagnostic interrupt: OB82, process
alarm: OB40).
Requirements
The following prerequisites must be satisfied for generation of parameterizable diagnostics
messages:
● The static basic parameter "Interrupt selection" must be set. See section on programming
in SIMATIC S7 (Page 57).
● The parameter "Interrupt generation" must be enabled for the associated interrupt. See
section on programming in SIMATIC S7 (Page 57).
No parameterizable diagnostic interrupts are triggered if these prerequisites are not fulfilled.
If these prerequisites are fulfilled, every change in the diagnostic state on the function module
or sensor results in a diagnostic interrupt.
Reactions to diagnostic interrupt in S7
Actions initiated by diagnostic interrupt:
● The diagnostics message is entered into the diagnostics of the function module.
● The red SF LED on the function module is lit.
● If you have parameterized "Enable diagnostics interrupt" with S7, the diagnostics data are
passed on to the CPU, and a diagnostics interrupt triggered which activates the OB82. The
red SF LED is lit. The diagnostics messages can be read in OB82.
Parallel to the OB82, the diagnostics message is automatically displayed in HW-Config without
a user program being involved (PLC > Module status, Diagnostics interrupt and Diagnostic
buffer).
Up to S7 V5.3, the diagnostic interrupt data are displayed as numbers, from V5.4 onwards in
plain text.
SE and PE are displayed in plain text in the diagnostic buffer (also when using S7 V5.3), and
the HE always as numbers.
You can find the diagnostics messages with their possible causes and remedies in the table
"Sensor and process errors" (Page 152) and in the table "Data and operating errors"
(Page 156).

● All SE / PE errors are set and reset errors, i.e. coming (C) and going (G) errors.
When an SE/PE error occurs, it is coming (C), and the most significant bit is set.
When an SE/PE error is no longer active, it is going (G), and the most significant bit is reset.
See also "Sensor and process errors (Page 152)"
● HE errors are events (no reset state).
SIMATIC error classes
● All sensor errors (SE LED On) are handled as internal errors (and as SF).
● All process errors (PE LED On) are handled as external errors (and as SF).
● All data and operating errors are handled as external errors (no LED On).

Example: Acknowledging coming (C) and going (G) PE/SE errors
Error "PE Pulse overflow" (PE error number 23) occurs, i.e. the error is coming.
● "ERR_MSG_C" = 97 hex = 1001 0111 bin and "ERR_MSG_TYPE" = 2.
● This indicates that you have a process error (type = 2) with error number 23 (PE Pulse
overflow) that is coming.
● To read the error number you use the number without coming error set bit i.e.
"ERR_MSG_C" = 0001 0111 bin = 17 hex = 23 decimal.
Error "PE Pulse overflow" is not longer active, i.e. the error is going.

SIFLOW FC070 with SIMATIC S7
Operating Instructions, 05/2012, A5E02254228-04 155
● "ERR_MSG_C" will have 97 hex as long as it is unacknowledged.
● When coming "PE Pulse overflow" error has been acknowledged ("ERR_MSG_Q" has been
set) the "ERR_MSG_C" the error status change from coming to going (from 1001 0111 bin
to 0001 0111 bin).
● When going "PE Pulse overflow" error has been acknowledged, "ERR_MSG_C" changes
from 17 hex (0001 0111 bin) to next unacknowledged error or to 0 if no unacknowledged
error resists.

12.8 System status information
SIFLOW FC070 with SIMATIC S7
Operating Instructions, 05/2012, A5E02254228-04 163
12.9 Slave diagnostics
The IM 153-x provides slave diagnostics in accordance with the standard IEC 61784-1:2002
Ed1 CP 3/1.
Note
The structure of the diagnostics data in case of slave diagnostics is described in detail in the
operating instructions for the ET 200M distributed I/O system. The following only provides
general information.
Information on "enhanced diagnostics" of the ET 200M
To be able to use the channel-specific diagnostics, you must enable the diagnostics interrupts
for each I/O module of the configuration.
When configuring the IM 153-x you can enable or block the diagnostics, process and hot
swapping interrupts, and you can do this independently of the enabling of "enhanced
diagnostics".
Via the DP V1 parameter (as of GSD Revision 3), you can block or enable the individual blocks
of the enhanced diagnostics. Blocked diagnostics will be removed from the diagnostics frame.
In order to delete channel errors from the diagnostics frame, you must switch off the "enhanced
diagnostics" in the configuration.
CAUTION
If you have enabled "enhanced diagnostics" during the configuration and a diagnostics
interrupt is triggered for a module only while the ET 200M is running, a channel error will not
be immediately entered in the diagnostics frame. A channel error will only be entered into the
diagnostics frame following triggering of the first diagnostics interrupt of the module generated
following enabling.
Note
Observe the differences in the diagnostics frame depending on the version of the IM 153-x
and on the release version. With IM 153-2Bx00 and IM 153-2Bxx1 the enhanced diagnostics
is available as default in DP V0 / DP V1 mode. It can be deselected (switched off) in blocks
during the configuration.
Interrupts
The interrupt part of the slave diagnostics provides information on the interrupt type and cause
that resulted in triggering of the slave diagnostics.
The ET 200M supports the following interrupts:
● Diagnostics interrupt
● Process interrupt
● Hot swapping interrupt
Alarm, error, and system messages
12.9 Slave diagnostics
SIFLOW FC070 with SIMATIC S7
164 Operating Instructions, 05/2012, A5E02254228-04
These interrupts can be evaluated using an S7 / M7 DP master or DP V1 master. In the event
of an interrupt, interrupt OBs are executed automatically in the master CPU.
The interrupt part encompasses a maximum of 29 bytes. A maximum of 1 interrupt can be
reported for each slave diagnostics.
Position in the diagnostics frame
The position of the interrupt part in the slave diagnostics depends on the configuration of the
diagnostics frame and on the number of channel-specific diagnostics. The interrupt part is
always the last part in the diagnostics frame.
● The bytes x to x+3 inform you of the interrupt type.
● The bytes x+4 to x+7 inform you of the interrupt cause. They correspond to the diagnostics
data record 0 in S7.
● Bytes x+4 to x+7 and x+8 to x+19 correspond to diagnostics data record 1 in S7.
Interrupts with a different DP master
If the ET 200M is being operated with a different DP master, these interrupts will be mapped
as device-related diagnostics of the ET 200M. You must continue to process the respective
diagnostics events in the user program of the DP master.

14.4 Troubleshooting sensor and unstable measurement values
14.4.1 General information
Incorrect and unstable measurements, especially at low flows, are typically a result of an
unstable zero point due to:
● Incorrect installation
● Air bubbles in the liquid
● Vibrations/Cross talk
● Solid particles in the liquid
In the following a 4-steps guide to troubleshooting is provided:
Step 1 Preliminary application inspection
Step 2 Zero point adjustment

Operating Instructions, 05/2012, A5E02254228-04 175
Step 3 Measurement error calculation
Step 4 Application improvement
The guide will enable you to trace the reason for incorrect measurements and to improve the
application.
14.4.2 Step 1: Inspecting the application
The first step in the troubleshooting procedure is to check for some easily resolved problems.
Check that:
● Sensor and SENSORPROM unit correspond (serial numbers)
● The sensor is properly installed.
● The sensor is located in a vibration-free position. Vibrations can disturb the sensor and
therefore cause measurement error.
● The sensor is filled with liquid and liquid only. Air or gas bubbles in the liquid cause instability
and can result in measurement errors.
Note
The liquid must be homogeneous in order to measure with high accuracy. If the liquid
contains solid particles of greater density than the liquid, then these solids can precipitate,
especially at low flow rates, which will cause instability in the sensor and lead to
measurement errors.
Resolving step 1 problems
1. Make sure that the serial numbers on the sensor and the SENSORPROM® unit are
identical.
2. Make sure that the sensor is installed as described in the installation chapter of the sensor
manual.
3. Flush the pipe systems and the sensor for several minutes at maximum flow rate to remove
any air bubbles which may be present.
14.4.3 Step 2: Performing a zero point adjustment
The second step in the troubleshooting procedure is to zero point adjust the device. For further
information on zero point adjustment, see the commissioning chapter.

14.4.4 Step 3: Calculating the measurement error
Calculating the measurement error
The result of the zero point adjustment will show you whether the zero point was set under
good and stable conditions. The lower the value of ZERO SIGMA, the lower the measuring
error.
For a well-installed flow meter, the ZERO SIGMA value is approximately the same order of
magnitude as the specified zero point error for the sensor size. The specified zero point errors
of MASS 2100 and MC2 are indicated below
Table 14-4 MASS 2100 / FC300 / FCS200 zero point error
Sensor size Zero point error/ZERO SIGMA value.

Di3 0.010 kg/h
DN4 0.010 kg/h
Di6 0.050 kg/h
Di15 0.2 kg/h
Di25 1.5 kg/h
Di40 6 kg/h
DN10 0.25 kg/h
DN15 1.2 kg/h
DN25 3 kg/h
Table 14-5 MC2 zero point error
Sensor size Zero point error/ZERO SIGMA value.
DN 20 0.6 kg/h
DN 25 0.96 kg/h
DN 40 2.85 kg/h
DN50 5.5 kg/h
DN65 11.4 kg/h
DN80 14.8 kg/h
DN100 25 kg/h
DN150 66 kg/h
Given the ZERO SIGMA value reading, it is possible to calculate the error which can be
expected for different flow rates, without performing time-consuming measurements. So using
this formula, one can assess if the application can be used as-is, or whether to use more time
improving the installation.
E = Z x 100% / Qm
E = measurement error in % of flow rate
Z = Zero Sigma value in kg/h
Qm = current flow rate in (kg/h)

14.4 Troubleshooting sensor and unstable measurement values
SIFLOW FC070 with SIMATIC S7
Operating Instructions, 05/2012, A5E02254228-04 177
Example 1: Low flow rate application
● Di 15 sensor. The sensor is specified to max. 5600 kg/h
● Zero point error/ZERO SIGMA value is specified as 0.2 kg/h
● Flow: Min. 10 kg/h - Max. 100 kg/h
After the zero point adjustment, the ZERO SIGMA value 'Z' is read as 1 kg/h, i.e. 5 times greater
than that specified for the sensor.
The error for a flow rate of 10 kg/h is estimated as:
● E = 1 kg/h x 100%/ 10 kg/h = 10%.
For a flow rate of 100 kg/h the error is estimated as:
● E = 1 kg/h x 100% / 100 kg/h = 1 %
For this application it is necessary to investigate more closely what the cause of the relatively
high ZERO SIGMA value is, in order to establish what needs to be done to improve the
measurement accuracy.
Example 2 : High flow rate application
● Di 15 sensor. The sensor flow rate is specified as max. 5600 kg/h
● The zero point error/ZERO SIGMA value is specified as 0.2 kg/h
● Flow rate: Min. 1000 kg/h - Max. 3000 kg/h
After the zero point adjustment, the ZERO SIGMA value 'Z' is read as 1 kg/h, i.e. 5 times greater
value than that specified for the sensor!
The error at a flow rate of 1000 kg/h is estimated as:
● E = 1 kg/h x 100%/ 1000 kg/h = 0.1%
At a flow rate of 3000 kg/h the error is estimated to be:
● E = 1 kg/h x 100% / 3000 kg/h = 0.03 %
Plus the linearity error of 0.1 %
As can be seen, in this case it is not so important that the zero point, i.e. ZERO SIGMA Value,
is 1 kg/h. The error due to the zero point is only 0.1 % for a flow rate of 1000 kg/h, and even
less for a higher flow rate.
So for this installation with the given flow rate and zero point error (ZERO SIGMA value), you
should typically choose not to spend more time finding ways to improve the application.
14.4.5 Step 4: Improving the application
It is not always worth while investing time and money in improving the installation and thus the
measurement accuracy. However, it should always be checked where the zero point error
(ZERO SIGMA value) originates from.
In the following it is described how to find the causes of a high ZERO SIGMA value and how
to improve the installation.

Setting "low flow cut-off"
In order to see if the zero point becomes more stable when making changes / adjustments,
the "low flow cut-off" must be set to 0.0%.
This is done from the transmitter:
MASS 6000 SIFLOW FC070
Choose menu entry "Basic settings"
→ Low flow cut-off
Choose PDM table
Choose input
When "low flow cut-off" has been set, it is possible to see the instability directly from the mass
flow in kg/h in the transmitter display or the online window "View → Display".
This information can be used to troubleshoot. For example, tightening the brackets which hold
the sensor, or turning off the pump to check if vibrations from the pump are disturbing the
sensor, etc.
Incorrect installation of the sensor
● Has the sensor been correctly installed, i.e. fastened to the floor/wall or frame with good
mounting brackets as shown in the instructions?
Especially for low flow rates, i.e. flow rates less than 10% of the maximum capacity of the
flowmeter, it is important that the sensor is correctly and stably installed.
If the sensor is not correctly fixed in place, the zero point of the sensor will change, leading to
measuring errors.
Try to tighten up the sensor brackets to see whether the flow instability is reduced.
Vibrations and cross talk
Vibrations in the pipe system are normally generated by pumps.
Typically, cross talk is generated by two sensors positioned in close proximity in the same
pipe, or installed upon the same rail or frame.
Vibrations/cross talk have a greater or lesser effect upon the zero point stability and therefore
also the measurement accuracy.
1. Check whether there are vibrations.
Turn off the pump and check whether the zero point stability improves, i.e. if the flow rate
fluctuation in kg/h is reduced.
If the sensor is disturbed by vibration from the pump, the installation should be improved
or the pump should be exchanged, e.g. to another type.
2. Check for cross talk.
Turn off the power to the other flowmeter(s) and wait approximately 2 minutes, so the
vibrating tubes in the sensor have stopped vibrating. Then check if the zero point stability
has improved, i.e. that the fluctuation in kg/h has been reduced. If this is the case, the
sensors disturb one another and the installation should be improved.

Air in the liquid
When air is present in the liquid, the zero point becomes unstable, which leads to a poor
measurement accuracy.
Checking for air:
● Check the Driver Current
MASS 6000 SIFLOW FC070
Menu entry
Service mode → Special information
Online menu:
View → Device status
● Check if the "Driver current" varies more than ± 1 mA. If this is the case, it is usually due
to the presence of air or gas bubbles in the liquid.
● Increase the pressure in the sensor, creating a large back pressure upon the sensor by
reducing the opening of the outlet valve or by increasing the pump pressure. Thereby the
size of air bubbles inside the sensor will be minimized. If the value or stability of "Driver
current" falls, it is proof that the liquid contains air or gas bubbles.
Typical causes of air in the liquid
● The entry pipe and sensor have not been properly filled with liquid. The pump cavitates,
the rotary speed of the pump is too high in relation to the supply of liquid to the pump.
● The flow rate in the pipe is too high, so components sitting in front of the flowmeter can
cause cavitation.
● If there is a filter installed before the flowmeter, it may be close to blocking, which also can
cause cavitation.
Solid particles in the liquid
If the solid particles in a liquid have a density higher than that of the liquid, they can precipitate
inside the sensor and cause instability which leads to a measurement error.
If solid particles are present in the liquid, they must be homogeneously distributed and have
the same density as the liquid. Otherwise they can cause relatively large measurement errors.
It is important that the sensor is installed such that solid particles can easily run out of the
sensor.
● For MASS 2100 sensors this is achieved by a nearly horizontal installation with the entry
highest and the outlet lowest.
● For MC2 sensors it is achieved by a vertical installation or by a nearly horizontal installation
with the entry highest and the outlet lowest.
1. Check if solid particles are present in the liquid:
Take a sample of the liquid, fill a glass and see if the solids precipitate.

Note
Min./max. values are integrated in the tables for better clarity. The relationship between a
data record and its associated min./max. values is as follows:
● Min. values: DR No. + 40 corresponds to the associated "Min." data record
● Max. values: DR No. + 80 corresponds to the associated "Max." data record.
Example: for DR 4, the min. values are in DR 44, and the max. values in DR 84.
The min./max. values are only module-internal values, i.e. the user program has no access
to the min./max. data records.
Note
Sensor dimension dependent parameters are read from the SENSORPROM®.

Default setting = -0.0005
344.0 2414 density_offset Density
offset
REAL (4) With this function you are able to make an offset in the
measured density (kg/m3).
● Min: -9999.9999
● Max: +9999.9999
Default setting = 0
If you want the flowmeter to show + 2 kg/m3 more, you can
change the density offset to 02.000 Kg/ m3 in the 'Sensor'
menu
348.0 2416 density_factor Density
factor
REAL (4) With this factor you are able to make a density correction
in % on the flowmeter.
● Min: -9.999999
● Max: +9.999999
Default setting = 1
The SIFLOW FC070 treats this factor as a normal number
and not as a percentage value: 1.0 in the device is 100 %.
If you want to change the density on the flowmeter by +0.5
%, you have to change the correction factor to 1.005. After
the change the flowmeter will now show a density about
0.5 % higher than before.

factor
REAL (4) Fraction factor (= b Table slope):
● Min: -9999.9999
● Max: +9999.9999
Default setting = 1
The SIFLOW FC070 treats this factor as a normal number
and not as a percentage value: 1.0 in the device is 100 %.
Example: If you want to change the concentration in % on
the flowmeter by +0.5 %, you have to change the fraction
factor 'b' to 1.005. Afterwards the flowmeter will show a
concentration 0.5 % higher than before.

For frequency outputs used in
controlling systems it is sometimes

to get a more stable system - or to
decrease the time constant to get a
faster and more precise measuring
system on the output signals.
The time constant Tau can be set to 0 ...

The output signal is damped
accordingly to following formula:
A = K( 1 - e -t/tau ) ; where Tau = time

ESD protective measures
When handling function modules and other components carrying this symbol, always observe
the ESD protection directives (Electrostatically Sensitive Devices/).
● Never touch the function modules unless necessary work makes this unavoidable.
● When handling the function modules, use a conductive and grounded work surface.
● Wear a grounding bracelet.
● Never touch chip pins, component connections or circuit board conductors when handling
the function modules.
● Never allow function modules or components to touch chargeable objects (plastics).
● Never place components or function modules in the vicinity of cathode ray tube units or
television sets (minimum distance: 10 cm).
● Leave the function modules in their special packaging until you are ready to use them. Do
not take the function modules out of their packaging or touch them when registering them
and so on.
● Function modules may only be installed or removed when the power is off.
● This warning sign on Siemens products draws your attention to appropriate protective
measures you need to take.

Glossary
ASIC
Application-Specific Integrated Circuit is an integrated circuit (IC) customized for a particular
use, rather than intended for general-purpose use.
BRIX
Degrees Brix (symbol °Bx) is a measurement of the mass ratio of dissolved sugar to water in
a liquid. A 25 °Bx solution is 25% (w/w), with 25 grams of sugar per 100 grams of solution.
CAN
Controller Area Network. CAN is the leading serial bus system for embedded control. CAN is
a mainstream network and was internationally standardized (ISO 11898–1) in 1993.
CIR
As of firmware V3.1, the SIMATIC S7-400 has been equipped with the system property
"Configuration in RUN". You can use "Configuration in RUN" to change the hardware
configuration and to start it up rapidly and cost-effectively while a plant is running. CiR
comprises the addition, removal and reparameterization of distributed slaves and modules on
PROFIBUS DP and PROFIBUS PA without interrupting the current production process.
Code block
A SIMATIC S7 code block contains elements of the STEP 7 user program. (In contrast to a
data block: this only contains data.)
Coriolis
The Coriolis effect is an apparent deflection of moving objects from a straight path when they
are viewed from a rotating frame of reference. The effect is named after Gaspard-Gustave
Coriolis, a French scientist who described it in 1835. The Coriolis effect is caused by the Coriolis
force, which appears in the equation of motion of an object in a rotating frame of reference.
Correction factor
With this factor you are able to make a flow correction in % on the flowmeter.
Flow rate (kg/h) = Correction factor x flow rate (kg/h).
If you want to change the flow on the flowmeter by +0.5 %, you have to change the correction
factor to 1.005 in the device menu 'Sensor characteristics'. After the change, the flowmeter
will show a flow rate 0.5 % higher than before for all flow-related values.

Density parameter
The density parameter is a constant found under the density calibration. This constant is used
to calculate the density of the fluid in the sensor.
● Density (kg/ m3) = A + B (1 + Density TC x temp.) * (1/(fr)^2).
● A = density parameter A (kg/m3).
● B = constant.
● Density TC = sensor’s density temperature coefficient (%/DegC).
● fr. = the sensor's resonance freq. (Hz).
Standard sensors without density calibration have average values stored in the
SENSORPROM
DFT
The discrete Fourier transform (DFT) is one of the specific forms of Fourier analysis. As such,
it transforms one function into another, which is called the frequency domain representation,
or simply the DFT, of the original function (which is often a function in the time domain). The
DFT evaluates enough frequency components to reconstruct the finite segment that was
analyzed. The DFT is thus a transform for Fourier analysis of finite-domain discrete-time
functions.
Diagnostics buffer
The diagnostics buffer represents a buffered memory area in the CPU. It stores diagnostics
events in the order of their occurrence. In STEP 7, you can select Target system > Module
status to read the cause of an error from the diagnostics buffer.
Diagnostics data
All diagnostics events are collected in the CPU and entered into the → Diagnostics buffer. An
error OB is started if present.
Diagnostics interrupt
Modules with diagnostics capability report system errors to the CPU by means of diagnostics
interrupts. The CPU operating system calls the OB82 in the event of a diagnostics interrupt.
EMC
Electromagnetic compatibility (EMC) is the branch of electrical sciences which studies the
unintentional generation, propagation and reception of electromagnetic energy with reference
to the unwanted effects (Electromagnetic Interference, or EMI) that such energy may induce.
The goal of EMC is the correct operation, in the same electromagnetic environment, of different
equipment which use electromagnetic phenomena, and the avoidance of any interference
effects.

Fraction
Fraction is defined as a part of a mixture. Mixtures consist of two components (A+B) which
can be measured separately. If the flowmeter is ordered with fraction, e.g. °BRIX, the flowmeter
is able to calculate the % concentration of sugar in a water (B) + sugar (A) mixture. In the
factory, the fraction factor b is set to 1.0000.
Formula: % concentration = a + b x % concentration = the concentration of media e.g. in °BRIX
● a = fraction offset in %
● b = is a factor without dimension
● x = is the concentration in % or e.g. °BRIX
Function block (FM)
According to IEC 1131-3, a function block (FB) is a → Code block with → Static data. An FB
allows the user program to pass parameters. Function blocks are therefore suitable for
programming frequently occurring complex functions, e.g. controls, mode selections.
Function module (FM)
A function module (FM) is a module which offloads the CPU of S7 and M7 automation systems
with respect to signal processing tasks which are time-critical or which require a large amount
of memory. FMs normally use the internal communications bus for fast exchange of data with
the CPU. Examples of FM applications: counting, positioning, control, weighing, measurement.
HART
HART Communication is a bi-directional industrial field communication protocol used to
communicate between intelligent field instruments and host systems. HART is the global
standard for smart process instrumentation and the majority of smart field devices installed in
plants worldwide are HART-enabled. HART technology is easy to use and very reliable
IP
An IP (Ingress Protection) number is used to specify the environmental protection of enclosures
around electronic equipment. These ratings are determined by specific tests. The IP number
is composed of two numbers, the first referring to the protection against solid objects and the
second against liquids. The higher the number, the better the protection. For example, in IP67
the first Number (6) means that the device is totally protected against dust, and the second
(7) that it is protected against the effect of immersion between 15cm and 1m
Modbus
Modbus is a serial communications protocol intended for use with programmable logic
controllers (PLCs). Modbus allows for communication between many devices connected to
the same network, for example a system that measures temperature and humidity and
communicates the results to a computer. Modbus is often used to connect a supervisory
computer with a remote terminal unit (RTU) in supervisory control and data acquisition systems.

Modbus master
A Modbus device that can access data in one or more connected Modbus slave devices.
Modbus slave
A Modbus device that can respond to requests from a single Modbus master.
NAMUR
Normenarbeitsgemeinschaft für Meß- und Regeltechnik in der Chemischen Industrie
(NAMUR). NAMUR is a group representing the interests of the chemical industry which creates
standards for instrumentation and electrical devices used in industrial plants.
Organization block
Organization blocks (OBs) form the interface between the CPU operating system and the user
program. The sequence for executing the user program is specified in the organization blocks.
PED
The Pressure Equipment Directive (97/23/EC) is the legislative framework on European level
for equipment subject to a pressure hazard. It was adopted by the European Parliament and
the European Council in May 1997 and has been obligatory throughout the European Union
since May 2002.
Plato
Plato is a measure of the weight of the solids dissolved in water. It is expressed in %.
Process interrupt
A process interrupt (hardware) is triggered by a module because of a certain event in the
process (upward or downward violation of a limit; module has completed the cyclic conversion
of its channels).
The process interrupt is reported to the CPU. The assigned → Organization block is then
processed according to the interrupt priority.
PROFIBUS
PROFIBUS (Process Field Bus) is a vendor-independent, open bus system standardized in
the German DIN 19 245. It is a standard for field bus communication in automation technology
and should not be confused with the PROFINET standard for industrial Ethernet. PROFIBUS-
PA (Process Automation) is one of three PROFIBUS variants that are compatible with each
other. PROFIBUS-DP (Decentralized Periphery).

Remote terminal unit = standard Modbus transmission mode
Safety Extra-Low Voltage (SELV)
IEC 61140 defines a SELV system as "an electrical system in which the voltage cannot exceed
ELV under normal conditions, and under single-fault conditions, including earth faults in other
circuits".
SENSORPROM
All sensor related settings/data saved on an EPROM. SENSORPROM technology
automatically configures the transmitter at start up providing calibration data, pipe size, sensor
type, and output settings. The SENSORPROM automatically stores values or settings changed
by users, and automatically re-programs any new transmitter without loss of accuracy.
Turndown ratio
'Turndown ratio' is a flow measurement term indicating the range a specific flowmeter, or meter
type, is able to measure with acceptable accuracy. It is also known as rangeability. If a gas
flow to be measured is expected to vary between 100,000 m³ per day and 1,000,000 m³ per
day, the specific application has a turndown ratio of 10:1. Therefore the meter requires a
turndown ratio of at least 10:1.
USM
USM II is a Communication Platform. The Siemens USM II concept enables fitting of add-on
bus modules without loss of functionality:
1. All modules can be fitted as true "plug & play"
2. Module and transmitter are automatically configured through the SENSORPROM
Zero point adjustment
The zero point adjustment must be performed in order to achieve the highest measuring
accuracy. In order to zero adjust the device, the flow must be completely stopped (‘zero flow’).
A manual zero point adjustment can be obtained through the menu in the transmitter.
