- 11 = The telegram configured in the SDB is too short for the selected telegram acc. to
$MN_DRIVE_TELEGRAM_TYPE.
- 20 = SDB contains too many slaves/devices, quantity
- 21 = SDB missing or contains invalid data, error code
- 22 = SDB configuration data incorrect, slave/device address, error code
- 23 = Reserved
- 24 = Reserved
- 25 = Reserved
- 26 = Reserved
- 27 = Reserved
- 28 = Reserved
- 29 = Reserved
Reaction:
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy:
Check that the corresponding SDB:
- Contains a diagnostic slot for every slave/device
- Contains only slave/device entries relevant to the application
In principle, it is possible to include a superset of slaves/devices in the SDB that are partially relevant for different end
versions of the product. However, this overloads the NC memory and runtime capacity and should, therefore, always
be avoided.
If this alarm occurs, reduce the SDB to a minimum.
If the code for the error cause is 03, check that equidistance is activated in the SDB (e.g. using STEP 7 HW config).
If the code for the error cause is 10, reduce the number of slaves/slots on the bus concerned (e.g. using STEP 7 HW
config).
If the alarm continues to occur, please send the error text to the control system manufacturer.
If the code for the error cause is 11, select a larger telegram as appropriate using STEP 7 HW config or
select a smaller telegram under $MN_DRIVE_TELEGRAM_TYPE.
Program
Switch control OFF - ON.

PROFIBUS/PROFINET: Multiple assignment of inputs on address %1
Parameters:
%1 = Logical address
Definitions:
Multiple assignments of input data have been detected in the logical address space. Logical address: Base address
of the address area defined several times
Reaction:
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy:
The address partitioning should be checked as follows:
Check for multiple assignments in the following machine data:
- MD13050 $MN_DRIVE_LOGIC_ADDRESS[0] - MD13050 $MN_DRIVE_LOGIC_ADDRESS[n-1] : n = highest axis
index on control system
- MD12970 $MN_PLC_DIG_IN_LOGIC_ADDRESS, MD12971 $MN_PLC_DIG_IN_NUM : PLC address area for dig-
ital inputs
- MD12978 $MN_PLC_ANA_IN_LOGIC_ADDRESS, MD12979 $MN_PLC_ANA_IN_NUM : PLC address area for
analog inputs
If no inconsistencies can be found in the parameters, compare these machine data with the configuration in SDB
(STEP 7 project). In particular, check that the lengths configured for the individual slots do not result in area overlaps.
When you find the cause of the error, change the machine data and/or SDB.
Program
Switch control OFF - ON.
