Parameters: %1 = Logical address Definitions: Multiple assignments of input data have been detect ed 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 - MD12974 $MN_PLC_DIG_OUT_LOGIC_ADDRESS, MD12975 $MN_PLC_DIG_OUT_NUM: PLC address area for digital outputs - MD12982 $MN_PLC_ANA_OUT_LOGIC_ADDR ESS, MD12983 $MN_PLC_ANA_OUT_NUM: PLC address area for analog outputs If no inconsistencies can be found in the parameters, compare these machine data with the configuration in the SDB (STEP 7 project). In particular, check that the lengths configured for the individual slots do not result in area overlaps. When you fi nd the cause of the error, change the machine data and/or SDB. Program Continuation: Switch control OFF - ON.
