If there are no tasks from the user program to be processed in the
SIMATIC TDC/SIMADYN D-CPU/FM 458-1 DP, then it goes into the
background processing mode to execute the background task.
The background task consists of:
• the test mode of the operating system in which for example, memory
test routines run
• and simultaneously a local service at the CPU front panel via the
diagnostics interface.
SIMADYN D subracks have an L bus and if required, a C bus. They
include the power supply- and data lines for the modules.
The cycle time of the CPU/FM 458-1 DP time generator is derived from
the sampling times of the individual cyclic tasks.
The basic sampling times of several CPUs are synchronized. In this
case, a CPU acts as master and sends its basic clock cycle along the
backplane bus. The synchronized CPUs do not generate their basic clock
cycle themselves, but take it from the backplane bus.
Also refer to: Interrupt synchronization
Using BICO technique, interconnections between I/Os of blocks can be
changed using Masterdrive operator control devices. This means that
configured software can be modified without CFC. Interconnections on a
technology CPU or SIMADYN D CPU module can be changed.
Also refer to: Technology connectors
Blocks are parts of the user program which are clearly defined as a result
of their function, structure or application. The CFC operates with pre-
configured block types, which are inserted in a chart. When inserting, an
instance is generated from a block type. These instances and their
graphic representation are blocks in the sense of the CFC.
Also refer to: Function block
Lower part of the block, which contains the I/Os.
The function blocks which can be called-up in the CFC, are sub-divided
into block classes, which include the functionality associated with the
particular blocks (e.g. closed-loop control blocks).
The upper part of the block, which among other things, contains the
name and the task assignment (run-time properties).
Block input or block output
Block I/O which can be connected with a block output or global operand
having the same data type, or which can also be parameterized with
values.
This consists of the I/Os of a block.

A block library includes a number of block types. A block library must be
imported into the CFC before its function blocks can be used in the CFC.
Also refer to: User library, System library, Code library
Block I/O which can be connected with block inputs and global operands
having the same data type.
Block types are pre-defined program sections which can be inserted into
a block library and into a CFC chart. Instances are generated. As many
instances as required can be set-up from a block type. For SIMATIC
TDC/SIMADYN D and FM 458-1 DP there are:
• Function blocks
• Block types generated from charts.
Also refer to: Block
The boot interface is the upper CF7 module connection, which is located
to the far left in the subrack.
Conditions for using the boot interface:
− An SS4- or SS52 sub-module is inserted in the boot interface
− The CPUs of the subrack are in the STOP condition after a boot
error.

HWConfig).
Also refer to: L bus
Function block to initialize and monitor couplings.
Continuous Function Chart. Configuring tool to define continuous
sequences in a user-friendly fashion by graphically interconnecting
complex function in the form of blocks.
Special graphic unit, which is generated using the CFC configuring tool.
A CFC chart comprises 1 to 26 chart partitions, each with 6 sheets, which
may contain overflow sheets.
The change memory is a memory area in which the configuring changes,
made with the CFC in the test mode are saved. It is located in the
memory module inserted in the CPU/FM 458-1 DP.
Area in a data interface, which is reserved for two or more
communication partners. The area can be set-up from the sender or from
the receiver. When firmware is the coupling partner, the area is always
set-up from a SIMADYN D CPU (and not from the firmware). A channel
always consists of a channel manager and one or two net data buffers.
Configuring engineers cannot directly access these areas.
Part of a channel, via which two coupling partners can communicate how
the net data buffers are to be interpreted. For instance, this indicates
whether new net data have just been entered or were already entered, or
if the last net data have already been read etc. Configuring engineers
cannot directly access this area.
Part of an address parameter. Channel names must always be specified
and allow senders and receivers to find their communication partner.
Thus, channel names must be uniquely assigned at each data interface.
Also refer to: Address stage
Refer to chart folder.
Container in the project structure; contains the charts of the user program
of a CPU/FM 458-1 DP.
A CFC chart can include an interface, which allows input- and output
parameters to be assigned to a chart. This means that the chart can be
used just like a block or can be compiled to create a block type.
A max. of 8 CFC charts can be nested. Charts generated in this fashion
are called nested charts.
Part of the CFC chart. A CFC chart is sub-divided into a maximum of 26
chart partitions (designated: A ... Z), each with 6 sheets.

utility consists of one or several function blocks.
• When compiling from the charts of a chart folder, either
• a runable user program is generated, which can be downloaded into a
CPU/FM 458-1 DP,
• or a user library is generated, which includes block types generated
from charts.
Also refer to: Consistency check, Loading

D
Connectors, which are used to jumper empty slots at the backplane bus
of a SIMADYN D subrack, where a module is not inserted.
The slots which require daisy-chain connectors can be seen in the
detailed view of HWConfig.
Data blocks are interfaces in the user program and are used to address
variables. Data blocks do not require any additional memory space.
There are
• instance data blocks, which are used to transfer data to WinCC, and
• data blocks, which include a user data area, to realize
communications with SIMATIC-OPs.
For interconnections and $ signals between different cyclic tasks, D7-
SYS guarantees that all of the transferred data are consistent. This
means that data, transferred from a task Ti, are taken from the same
computation cycle of this task.
If a signal is to be transferred without deadtime, it is possible to bypass
data consistency ($ signal, "Fast" type or by interconnecting with a
pseudocomment DATX).
Also refer to: Process image
Permanently structured memory medium (e.g. dual port RAM), which two
coupling partners can access to transfer data.
The structure defines how the data interface is configured (e.g. where
general initialization data are deposited, the data memory size and what
is still available). The data interface structure is the same for all
couplings. The contents of the data interface structure are of no
importance for the user, because when configuring couplings, memory
areas do not have to be explicitly addressed.
Configurable data transfer mechanism for senders and receivers.
Handshake, refresh, select and multiple modi can be selected. Senders
and receivers must have the same configured data transmission mode;
otherwise, they will not be able to synchronize with one another and
exchange data.
Also refer to: Channel
Each I/O of a block is assigned a particular data type. It defines the value
range, resolution, display and interpretation of values at this input or
output.
"BOOL" defines, for example, a binary variable, "INT" defines a 16-bit
fixed-point variable.
If a connected block input is to receive its values from a connected
output, bypassing the data consistency mechanisms, then it must be
marked with a pseudocomment "@DATX".

The diagnostics buffer is a buffered memory area for CPU/FM 458-1 DP-
modules CPU, which is structured as a ring buffer. Diagnostic events are
saved in the sequence in which they occurred.
A diagnostics event makes an entry into the diagnostics buffer of the
CPU/FM 458-1 DP. A differentiation is made between diagnostics events
as follows:
• Errors while initializing ("0" or IF-LED)
• Monitoring errors ("b" or MF-LED)
• Communication errors ("C" or CF-LED)
• Task administration errors ("E" or TF-LED)
• User errors ("A" or UF-LED)
(with function block USF diagnostics event defined by the user)
• Operating mode transitions (e.g. from RUN to STOP)
Serial interface at the front panel of a SIMADYN D-CPU module. This
interface permits local access to this CPU with the CFC in the test mode
for troubleshooting, testing and start-up.
Display devices are used in order to intervene in the process and display
the current process status.
A $ signal is used to interconnect function blocks, which run on different
CPUs within the same SIMADYN D station.
When configuring a $ signal, its signal name as well as type and bus
assignment must be specified.
The $ signal type determines whether data transfer is to be consistent
("standard") or should bypass the data consistency mechanisms ("Fast").
The bus assignment defines which of the two backplane buses are used
for data transfer.
Also refer to: Global operand, Virtual connection, Data consistency

The enable attribute is a run-time attribute. It activates and de-activates a
run-time group. While de-activated, the group is not executed,
independent of all other conditions.
When you interconnect a block output, data type BOOL with the run-time
group, the value of this block output then decides as to whether the group
is activated or de-activated.
Contrary to cyclic tasks, interrupt tasks are not started at equidistant time
intervals, but when a process interrupt occurs.
Certain function blocks (e.g. control blocks) are configured so that they
are called-up at regular time intervals. If these are to be configured in an
interrupt task, then an equivalent sampling time must be configured in
HWConfig. for this interrupt task. This should correspond to the average
time between two consecutive process interrupts.
If the basic clock is not generated by an internal clock generator, but from
a process interrupt, or if it is synchronized to the basic clock of another
CPU (basic clock synchronization), then an equivalent sampling time can
be specified for the basic clock.
Also refer to: Sampling time
Errors/faults related to the hardware, operating systems and the user
program are recorded in the error field of a CPU/FM 458-1 DP. In the test
mode of the CFC, this error field can be read-out and analyzed for
diagnostics.
In the exception buffer of a CPU/FM 458-1 DP (this is not available for
type T400 CPUs) when goes into the STOP condition, information is
recorded, which permits the error cause to be identified. The exception
buffer can be read-out and analyzed in the test mode of the CFC.
The contents of the exception buffer are retained, even if a subrack is
reset, or is isolated from the power supply, under the assumption, that a
battery is inserted in the subrack.
Peripheral module to input and/or output process signals such as
analog-, digital inputs/outputs or speed sensing signals. When connected
directly to a CPU board, bypassing the backplane bus they relieve the
backplane bus and allow process signals to be sensed at extremely high
data rates.

An initialization value can be specified at block outputs. This value is at
the output, if the block is calculated for the first time in the INIT operating
status.
It may be necessary and practical to specify an initialization value, if:
− an output is connected to the input of a block, which is executed
first, or
− the status of the block output defines the internal status of the
block (e.g. the Q output of a flipflop block).
Also refer to: Run-time properties, Parameters (1)
Peripheral module to input and/or output process signals.
When a block is instanced, this ensures that the instance of the block
type (block) can run in its configured environment.
Using an instance data block, display devices can access block I/O. An
instance data block is automatically generated in the CFC and is
permanently assigned to a block.
Connecting a block output or block input with another element:
• Block output - block input
• Block output - global operand
• Block output - run-time group
• Global operand - block input
The value of the connected input is retrieved from the other end of the

If a SIMADYN D CPU identifies a fatal system error, it goes into the
STOP condition, and informs the other modules in the station using a
system exception signal.
Another module can ignore this system exception signal, and continue to
operate, or it can also go into the STOP condition.
Also refer to: Exception buffer
If a SIMATIC TDC module identifies a critical system fault/error, then it
goes into the STOP operating mode. It then sends a system exception
message to the first CPU of the station.
As a response, it can be defined as to whether the remaining modules in
the station continue to operate or the complete station should go into the
STOP condition.
