1 Overview
This description of the function block concerns the data transfer between the STEP–5 program and the
ASM 400 interface module.
The FB 250 can be installed in the following programmable logic controllers without modification:
115U/941/942/943/944/945/115F
135U–R/S/CPU928B
155U/155H
FB 250 can be used equally for all MOBY systems (MOBY I/E/F/V/L/U).
This is possible when the FB 250 does not use any system commands.
All data storage memories can also be processed with FB 250.
Essential functions of the FB 250 are:
– Conditioning of the data structure from the user parameters to an ASM
data structure
– Complete data communication with ASM using commands and data exchange
– Error handling:
Repetition of commands: conditioning of errors for the user
Chaining of several part commands into a complete command:
– Read and write are possible with one user command.
– Any number of address areas of an MDS can be processed with one command.
– Control of the PLC cycle load by the user
Data transfer between the FB and the MDS can be divided into three parts:
– Provision of the interface card with the necessary command and the parameters
or data
– Transfer of the data between the interface and the data memory
– Provision of the S5 with the data and parameters from the interface card
An additional function block with the designation FB 252 has been added to the “MOBY Software” CD.
As seen by the user, the FB 252 works with the same interface as the FB 250. The only difference be-
tween the two FBs is the addressing of the ASM 400 MOBY interface module in the SIMATIC.
FB 250: P–area; Max of 32 channels or 8 interface modules
FB 252: Q–area; Max of 64 channels or 16 interface modules
This increases the maximum number of channels from 32 to 96.
The ASM 400 can also be parameterized as a dialog station so that data can be transferred from one SLG
to another.
Caution:
The Q-area is only available in PLCs S5-135U, S5-155U, and S5-115U with CPU 945.

Description of the Control Bits in BEST:
BIT 0 RESET Reset of a read or write command
After the first commissioning and every subsequent change to the ADR,
KAN, TYP, FBDB and ANW parameters, the user should initiate a RESET
so that a parameter check, and construction of the command in FBDB, can
be carried out new.
BIT 1 Read/write Start signal for the FB: Execution of the command in the reference list.
start After starting the execution of the command the bit will be reset by the
FB.
BIT 2 New start Set by the user after new start and after return of power .The function is the
same as RESET. The bit is also accessed during the processing of the
command.
BIT 4 RESET Positive acknowledgment of the RESET command (BIT 0)
active/ready This bit is set when a command from the ASM is processed by the STG.
BIT 5 Command Positive acknowledgment of read/write (BIT 1)
active/ready
BIT 6 STG active When this bit is set by the FB this delays the execution of a MOBY
ASM test command for a short period. This bit can be set for several reasons.
a) The ASM has received a command from the STG (service and test
device) and is just carrying it out.
b) After switching on the SIMATIC S5 the ASM 400 carries out an
extensive self–test. During this time (about 3 seconds) the module
cannot be accessed. The bit is automatically reset after the self–test.
The module reports with READY in BEST.
c) A RESET/new start is active on the ASM (MOBY U).
BIT 7 FB active The FB is active with the execution of a command.
When bit 7 is set, bit 15 is reset.
BIT 8 to11 In reserve
BIT 12 Availability This bit is only set when the “ANW” parameter is set at “1” during the
parameterization of the FB call (see chapter 5).
0 = No MDS is in the SLG field.
1 = MDS is now in the SLG field.
BIT 13 BATT The MDS battery check has been triggered (only for RAM MDSs).
The remaining battery capacity can only hold for a few months at room tem-
perature. It is recommended to immediately change the battery anyway –
or the MDS if it is not a battery–replaceable MDS.
BIT 14 Error “ERROR” is set by the FB when a problem occurs with the reset, read
or write commands. The exact cause of the error is located in data word
“ANZ” (= DW 5). A RESET is required after an error. The start of a read/
write command resets the ERROR bit.
BIT 15 READY – The last command (reset, read, write) has ended.
– The user can start a new (reset, read, write) command.
Note: READY does not need to be set to start a new RESET command.

Includes the requirements of FB 250
The user must set up an FBDB with a minimum of 25 DWs for each
channel module of an ASM 400. The FBDB is determined during parameteriza-
(See also chapter 2.2.2 for parameters to be supplied.)
This data block includes the command(s) with which an MDS will
be processed. Several FBDBs can work with the same commands in one
Minimum length of the DB for a command = 6
Data block with user data for reading and writing
Several commands in ZUWDB can refer to the same DATDB.
Minimum length for a data byte = 4

FBDB, ZUWDB and DATDB can be combined through appropriate configuration in a data block
(see chapter 4.6.1).
Note: ZUWDB and DATDB in a combined data block may not be used by another FBDB.

2.4 Start Up
Special steps are needed to correctly start up the ASM and FB when performing a new start or restart.
The FB 250 must be supplied with the “new start = 1” parameter in the new start and restart OB (see
chapter 4.5).
Special features of startup of high-speed SIMATIC CPUs:
When MOBY is used in an S5-115U/CPU 945 or S5-155U/CPU 948, the presence check (ANW = 1) to be
enabled may not be accepted by the ASM 400. Use the following programming strategy for new start and
restart.
W ait for READY after the RESET command is started (call FB 250). Then wait at least another 10 msec
before starting FB 250 with a MOBY command.
2.5 Addressing the Module
ADR and KAN parameters are used to set the physical address of the modules. One ASM 400 occupies
16 peripheral bytes in the address area between 128 and 255. The P-area or Q-area setting must be
performed in the expansion device interface in the SIMATIC S5.
These are the relevant allocations.

3 Command Chain
General Performance Notes:
– One data storage operation consisting of several commands can be combined into a command with
several part commands.
– The user can read and write to an MDS with one command.
– Any number of address areas of an MDS can be processed with a chained command.
– The data transfer of a chained command can be programmed by the user and distributed over
several cycles.

3.3 Maximum Chain Parameters
The chaining of commands is limited through:
a) Max. number of commands in a ZUWDB
b) The available RAM on the ASM
c) Cycle time
to a) Since the first 3 data words are reserved in ZUWDB, up to 253 data words are available to the
user for his commands. This means that a maximum of 84 commands (= 253/3) are
available.
to b) 12 Kbytes of RAM on the ASM are available to the user . A byte quantity of “data length + 8” is
needed on the ASM for each chained part command. Error “1D” is reported if the RAM
area on the ASM is too small.
Example: 8453 bytes (i.e., 8189+33x8) are reserved on the ASM for read–accessing an
entire 8–K MDS with a chained command.
33 commands each are stored in ZUWDB for read and write–accesses to
the MDS.
to c) In order not to exceed a given cycle load by the FB 250 the user can program one or several
cycle changes in one chained command (see table in chapter 2.1).
Note: When reading: A programmed cycle change will only be carried out in the results
phase. When writing: The programmed cycle change will only be carried out
during the command transfer phase.

KEY:
Cycle change in PLC
Run time of FB 250 in PLC (cycle load by the FB)
Run time of the other user program in the PLC
* The actual distribution of the cycles in the result phase can differ from the programmed distribution.
The ASM processes the part commands in order in which they were transferred.
The ASM provides the first partial result as soon as the first part command is processed.
The PLC fetches the queued results from the ASM during the next cycle but never later than the
programmed cycle change. This means:
The user programmed maximum cycle load is never exceeded.
Note:
The processing of single part commands by the ASM to MDS occurs exactly in the sequence in which the
part commands are programmed in the ZUWDB.

3.5 Special Commands
Special commands are used to parameterize new MDS types correctly. A special command is called
when FB 250 is called with the following parameterization.
TYP = 3
FB 250 must be switched back to normal operation (typ = 5, 6) after a special command has been
processed. It is absolutely necessary that a reset be performed after the switchover.
Processing of a special command is divided into several stages.
Parameterize FB 250 call with TYP=3.
Start RESET command.
Start special command(s).
Parameterize FB 250 call with TYP=5, 6.
Start RESET command.
FB 205 is ready for normal commands.

04 01 0003 1st data byte: 01 = Switch on dialog operation
A 16–Kbyte VMDS (virtual mobile data
memory) is set up on the ASM. The VMDS
is used for communication memory during
dialog operation. When dialog is switched
on, the VMDS is automatically cleared to
00. Dialog operation must be switched on
again each time power is turned on.
When the SIMATIC is switched of f, the data
on the VMDS are lost.
Note:
Dialog operation may only be
switched on on one side of the
communicating ASMs. The other side
operates in normal mode.
ECC operation is not possible with the
VMDS.
Dialog operation can only be
switched off by switching off the
SIMATIC.
ANW (presence) can be switched on or
of f. If on, the ANW bit in DW 5
indicates the presence of another SLG.

4 This command only applies to MOBY U. Remember: When the FB 250 call changes from TYP = 3 to TYP = 5,
6, a RESET is performed on the ASM/SLG and the antenna is turned on again automatically. This is the reason
the FB 250 call must remain TYP = 3 until the antenna is to be turned on again.
Caution: MDS 507/407E processing: An MDS 507/407E must be switched on with command code 04,

4.2 Processing the MDS Data Storage
Mobile MDSs with various memories are available for the user. The following types are available:
– 62 (42)* Byte RAM (e.g., MDS 115)
– 128 (112)* Byte EEPROM (e.g., MDS 213E)
– 2 (1.7)* Kbyte RAM (e.g., MDS 302)
– 8 (7)* Kbyte EEPROM (e.g., MDS 413E)
– 16 Kbyte RAM (VMDS = virtual MDS for dialog)
– 32 (28)* Kbyte RAM (e.g., MDS 505)
– 752 Byte EEPROM (MOBY E)
– 40 Bit Fixed code (MOBY F MDS 1xx)
– 16 Byte EEPROM (MOBY F MDS 2xx)
– 192 Byte EEPROM (MOBY F MDS 4xx)
– 2 KByte RAM (MOBY U MDS U313)
16 Byte OTP
– 32 KByte RAM (MOBY U MDS U524)
16 Byte OTP
* Net capacity with ECC mode
The data memory addressing occurs linearly from the start address to the final address. The ASM auto-
matically recognizes the memory capacity on the MDS. If the final address is exceeded the user receives
an error message.
The following table shows the address areas of the individual MDS models.

4.3 Initializing the MDS
Function:
The total MDS memory is written with “00.”
Required: – When a new MDS which has never been write accessed is used
– After battery exchange or failure
– When an MDS is to be used in ECC mode
The “MDS RAM error in memory” (04hex) information is deleted.The initialization cannot be executed with
a “normal” write command to the MDS since a different protocol is required.
The initialization command is not required during normal operation.
The initialization is set by a different type of command during parameterization to avoid incorrect operator
inputs.
Parameter Example:
***** E X A M P L E: Call of FB 250 and Parameterization for Initialization *******
0000 :A DB250 FBDB call
0002 :UN –HILF If the pointer is not yet set...

32K Byte MDS (RAM/FRAM) : Approx. 2 53
752 Byte MDS (MOBY E) : Approx. 0.8 –
192 Byte MDS (MOBY F) : Approx. 2.2 –
2K Byte MDS (MOBY U) : Approx. 1 –
32K Byte MDS (MOBY U) : Approx. 1.5 –
Type = 1 (Without ECC) [s] Type = 2 (With ECC) [s]
An error message occurs if the MDS cannot be initialized.
* Earlier method of parameterization for the initialization with type 0 and 1 can still be used.

4.7 Setup of a Dialog Transmission with ASM 400
The dialog function of MOBY I can be used to transfer data from one interface module to another interface
module.
To activate dialog operation on the ASM 400, the user must send a special command to the ASM (cf.
chapter 3.5), and then switch to normal operation again.
Note:
An activated dialog operation can only be reset by switching off the module.
4.7.1 How Is the MOBY I Dialog Set Up ?

Station_N Normal ASM of MOBY I (ASM 400, ASM 410, ASM 420, ASM 440, ASM 470,
SIM4x)
The user operates station_N as usual (i.e., as if he/she wanted to exchange
data with an MDS).
SLG_N An SLG (SLG 41, SLG 42, SLG 43, SLG 44) which is connected to station_N
Station_D Dialog ASM of MOBY I (ASM 400, ASM 410, ASM 470)
When turned on, station_D is parameterized as dialog ASM with a user
command. A 16-Kbyte memory area is defined in station_D during parameter
assignment. This memory area is called VMDS (i.e., virtual MDS). It is used
as communication memory. Processing of station_D by the user is identical
to the program in station_N. Station_D uses the same tools as station_N
(e.g., FB 47).
SLG_D An SLG (SLG 41, SLG 42, SLG 43, SLG 44) which is connected to station_D
VMDS Virtual mobile data memory. The VMDS is a 16-Kbyte area of memory on
station_D. This VMDS is defined and cleared when station_D is turned on
and parameterized.

4.7.2 How does the User Work with MOBY I Dialog?
Example
The user program in station_D issues a write command with the data to be transferred. The command is
executed immediately. The data are now located in the VMDS. This concludes work in station_D. The
user program in station_N issues a read command. SLG_N and SLG_D do not yet have to be positioned
opposite each other in the transmission window. Reading of the desired data starts as soon as SLG_D
moves into the transmission window of SLG_N. The data are read from the VMDS and transferred to the
user on station_N.
Communication time during dialog
The same times as described in the MOBY catalog apply for configuration of the communication time.
tk = 16 msec + 0,8 ms * nBytes
Transmission window during dialog
The transmission window from SLG_D to SLG_N has a polarization direction (i.e., SLG_D and SLG_N
must be directed toward each other at a certain angle). The following figure shows the transmission w i n-
dow during dialog.

Dialog with ECC
ECC operation must always be deactivated during dialog operation.
New start of an ASM 400 as station_D
When dialog operation is activated, the ASM 400 checks to determine whether the SLG is connected cor-
rectly and supplied with power. If not, the red LED on the channel module continuously indicates a triple
flashing pattern. FB 250 does not give the user an error message.

5 Control and Inquiry for “Data Storage MDSs in the Field”
The “ANW” parameter can be set to 2 operating modes of the SLG using FB 250.
ANW = 0
The magnetic field of the SLG is only switched on when a valid command is started. After recognizing the
MDS and the completion of a command, the SLG is turned off again.
In this way projects can be implemented in which the specified distance between SLGs can be passed
below as desired. The prerequisite is that the SLGs that are close to each other are addressed in
multiplexer mode. This can be necessary when large amounts of data need to be dynamically transferred.
You can avoid stopping the transport conveyor by dividing up the data and distributing it over several
consecutive SLGs.
ANW = 1
After a new start or restart of the PLC, or after a new start or RESET command of the FB 250, the SLG is
switched on and remains active until the PLC is switched off.
The ASM scans continually to see if an MDS is in the field of the SLG. When the ASM recognizes an MDS,
the user receives “availability bit” = 1 (= BEST bit 12) with the next FB call. Similarly, BEST bit = 0 when the
MDS leaves the SLG field.
If the MDS stays exactly on the edge of the SLG field, the system ensures that there is no constant switch-
ing of this bit. The processor on the ASM handles this hysteresis function.
Read/write commands can be sent completely transparently to FB 250 for the “availability” check. Simi-
larly, the “availability bit” retains its unrestricted validity after the start of a command.
Note: When working with ANW = 1, it is absolutely essential that the distance between two
SLGs specified in the configuration guidelines be adhered to.
Remark: The FB 250 cycle load will not be altered by the setting of the “ANW” parameter. The
values in the table in chapter 2.1 are applicable in every case.

Switching “Availability” Monitoring On and Off
This occurs with the switching on and off of the PLC. By calling the FB 250 with dif ferent parameters and
carrying out a RESET command, the “availability” monitor can also be switched.

6 Commissioning the ASM 400 with FB 250
6.1 Module Ports
– Set free address in the SIMATIC S5 on the S3 address switch (see chapter 2.5).
– Plug in the module.
Note: Plugging i n o r extracting the module or a channel module may only occur when the power
has been switched off.
6.2 Loading FB 250
– Load the FB into the user program.
6.3 Presetting the Organization Blocks
– Preset the “BEST” parameters in the OB for new start and restart as follows:
For restart 0004hex
For new start 0004hex
Tip: The corresponding OBs are to be found in the relevant SIMATIC catalogue
(see also chapter 4.5).
Example: S5–155U OB20 for new start
OB21 and OB22 for restart
Note: The “BEST” must be preset in every FBDB if several SLGs are to be used with one PLC.
6.4 Setting Up the Data Block
– Set up data block for FBDB parameter (minimum length: 25 DW).
A separate FBDB must be set up for each channel.
– Set up data block for “ZUW” parameter (see chapter 2.2.5).
– Set up the DATDB specified in the ZUWDB.
6.5 Calling FB 250 in the Application Program
– The FB 250 must always be called absolutely.
– The parameters – “ADR,” “KAN,” “TYP,” “FBDB” and “ANW” are to be established
(see parameterization in chapter 2.2).
6.6 Program Processing
– Call the user program (e.g., in OB1, cyclic call).

or
A reset command is required if the above parameter states are not kept. If both parameters still have
other values, continue with the error description.
6.7.2 Command Input
”BEST”: 00000000 00000010
Command in ZUWDB to be processed (read/write)
”ANZ” : 00100000 00000100 Synchro (general communication possible)
(Reserved)
(with Control VAR on the PG) and:
”BEST”: 00000000 10100000
Command (read or write) is active.
FB is running.
The states of these two parameters are retained until an MDS enters the field of the SLG and the
command is correctly processed with the MDS.
6.7.3 Command Executed
”BEST”: 10000000 00100000 Read/write finished
”ANZ” : 00000000 00000100 Synchro
No error with the command execution
READY
The “BEST” and “ANZ” values have the same states for read and write.
After carrying out the commands both parameters go back to their basic state (6.7.1) (and a read or
write ready message).
If an error is detected and one of the parameters deviates from the above figure, continue with the
error description.

7 The ECC Driver
The ECC driver (Error Correction Code) can be started using an option in the ASM 400 firmware.
The operating mode is switched on with the “typ” parameter during parameterization. The ECC driver ca n
only be used by MOBY I.
Application:
The ECC driver provides extra security for the correct data being on the MDS. For EEPROM MDSs, only a
write frequency of 10,000 operations is guaranteed by the manufacturer. Using the ECC driver provides
the same data security right up to the actual end of the chip’s life.
The ECC driver can also be used for security reasons with RAM MDSs for instance where extreme distur-
bance fields can affect communication.
Call Up:
The programmer must only consider the correct “TYP” parameter when installing the system.
TYP = 3 Initialize the MDS with ECC (subcode 0002)
TYP = 5 Write and read the MDS with ECC
All other parameters such as, for example,
– Construction of the MDS data structure
– Start address and length in the command
– Construction of ZUWDB or DATDB
do not need to be altered.
Chapters 1 to 6 of this description also apply when the ECC driver is switched on.
Function:
The ECC driver divides the MDS memory into 16–byte blocks. 14 bytes are for user information and 2 by-
tes for ECC information. With every access to the MDS at least one block is read or written to (even when
the programmer has only programmed 1 byte in ZUWDB). Therefore, the access time is lengthened to the
MDS data (see the table in the catalog). When an ECC MDS is read without the ECC driver (e.g., with
“TYP” = 6 o r with the STG), the ECC bytes can be distinguished from among the user data. When an ECC
MDS is overwritten without the ECC driver, the MDS’s data structure is destroyed. The MDS (or the de-
stroyed data block) can no longer be read with the ECC driver.
Data Correction:
If one bit of data in the MDS’s memory is lost at some time (e.g., EEPROM MDS which has been write
accessed very frequently), the ECC driver is able to reconstruct the lost bit. The user is guaranteed to get
his correct data back. The user can use a status bit in the indication word (ANZ Bit 13) to request and
evaluate the corrected data (e.g., to decide whether the MDS should be replaced soon).

Please Note:
– The access times on the MDS are lengthened since less data can be processed in dynamic mode.
– The net capacity of the MDS is smaller (see chapter 4.2).
– The result can be delayed by up to one second when data correction takes place.
– A “normal” MDS must be initialized with the ECC driver switched on (e.g., with the STG) before
being commissioned.
– During dialog mode, the VMDS cannot operate with ECC.

8 Error Searching with the ASM 400 and FB 250
Error: The program does not run after new start or restart.
Cause: –> The organization block for new start and restart was not preset according to the
relevant FB description.
–> The synchro bit in ANZ (DW 5) has been reset.
Error : The PLC goes into STOP status after the MOBY blocks are loaded.
Cause: The parameterized FBDB is not available or is too short.
– Exact error analysis in the ISTACK output of the programming unit
Error: The PLC goes into STOP status after starting or carrying out a command.
Cause: – ZUWDB or DATDB is not available in the PLC.
– The accessed data word in ZUWDB or DATDB is not available
(ZUWDB or DATDB are set up too small).
– After loading the FBDB, no reset was carried out.
– The ZUW parameter (= DW6 in FBDB) was not supplied.
– Too much data was transferred between the ASM and the FB with a chained command
so that the maximum cycle time of the PLC was exceeded. (The ISTACK of the PLC
indicates “ZYK” as the cause.)
Remedy: Program a chained command with a cycle change (see chapter 3.2).
– The user program has changed the data in the FBDB (particularly DW 0/1).
If FB 250 does not work correctly, further errors can be analysed by checking the “ANZ” parameter. “ANZ”
contains the following contents when no command is active.
1 = Timing error
1 = Repeat error
ASM status byte
1 = Parameterization error
1 = ASM error
1 = Synchronization error
0000 0000 0000 0001
0 = The FB is not operating (output RESET).
“ANZ”
The left byte in the “ANZ” parameter contains the ASM status. Evaluation with the bit pattern is described
on pages 40 and 41.

(4)J31069-D0120-U001-A2-7618
Bit 1: = “1”: Synchronization error
Cause: – The FB 250 receives a result for a command that is not in the ZUWDB (not at this
location). Possibly the pointer (ZUW) to ZUWDB was altered while the command was
active.
– EMC conditions caused the ASM to process another command than the one
programmed by the user.
Check the entire SIMATIC system. Check grounding concept.
Bit 2: = “1”: FB 250 is synchronized (SYNCH).
General communications possibility with an ASM 400 channel module. This bit is set after
a positive check of the FB parameterization. This happens with the first RESET right after
initial loading of the programs and data blocks. If the RESET command does not work this
bit is not set or reset.
Cause: ASM 400 cannot be addressed by the FB.
– Wrong address set on the ASM 400
– ASM 400 defective
The RESET should always be carried out after a reset synchro bit.
Bit 4: = “1”: Parameterization error
Cause: – The “ADR” parameter does not contain the values specified in chapter 2.5.
– The “KAN” parameter is specified incorrectly (permissible values: 1 or 2).
– The “TYP” parameter was specified incorrectly (permissible values: 0, 1, 3, 5, 6).
– The “ANW” parameter is not “0” or “1”.
– The command in ZUWDB is not allowed.
Bit 5: = “1”: ASM error
Cause: – The exact ASM error is located in bits 8 to 15 of ANZ.
If bits 8 to 15 = 0:
– The FB did not get an acknowledgment in time from the ASM after transfer of a
command.
– After start of a command, the user did not call the FB 250 within 4 seconds (no cyclic call
of the FB).
– The user has modified data in the FBDB (DW 0 to DW 24) (particularly DW 0/1).
Bit 6: = “1”: Time error
Cause: Loop counter monitor in FB 250 was triggered.
– The command data could not wholly or in part be transferred to the ASM 400.
– The ASM 400 cannot be accessed by the FB. Possibly the “ADR” parameter does
not correlate with switch S3 on the ASM 400 (see chapter 2.5).
– A write command contains length = 0.
– The PLC parameter is set wrong (see chapter 2.2.2).
– The user has modified data in the FBDB (particularly DW 0/1).
––> ASM 400 hardware, addresses, parameters and user program should be checked.

(4)J31069-D0120-U001-A2-7618
Bit 7: = “1”: Repeat error
Cause: The command to the ASM 400 was repeated.
– Error in BEST = 0: The command was concluded correctly after a repeated
command (no error)
– Error in BEST = 1: Communication between ASM and FB 250 is interrupted.
Despite repetition of the command the command could not be
correctly executed.
A complete hardware check is required if the repetition bit is set sporadically. Special
attention should be paid to the grounding concept.
Bit 13: = “1”: ECC correction was performed.

Pure Hardware Errors
If the ASM is not working correctly and there is no error to analyse – the following points should be
checked.
– Power supply (especially if the power supply also supplies an expansion rack)
5 V under load
24 V under load
– Wiring for ground
See catalogue.
Check cabling. (See installation guidelines catalogue.)
Otherwise the SIMATIC S5 wiring guidelines apply.
– Shielding
Apply on both sides.
– Cable (See MOBY manual for configuration, installation and service.)
Use correct cable to the SLG.
Check the cable length (see cable configuration).
– Cable installation
SLG and ASM plugs correct?
Are distribution sockets built into the connection?
– Site Metalfree rooms are required (see installation guidelines in the catalogue).
Maintain working distances (see technical data in catalogue).
Maintain minimum distances MDS <––> MDS
SLG <––> SLG
(See technical data in catalogue.)
