Profibus-DP: multiple assignment of outputs on address %1



%1 = Logical address

Multiple assignments of input data have been detected in the logical address space. Logical address: Base address of the address area defined several times


-    Channel not ready.

-    NC Start disable in this channel.


-    Interface signals are set.

-    Alarm display.

The address partitioning should be checked as follows:

Check for multiple assignments in the following machine data:

MD 13050[1] - MD 13050[n]: n = highest axis index on control system

MD 12974, 12975: PLC address area for digital outputs

MD 12982, 12983: PLC address area for analog outputs

If no inconsistencies can be found in the parameters, compare the machine data with the configuration in SDB1000. 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 SDB1000.

Program Continuation:

Switch control OFF - ON.
