Decoded M signals
General
The M functions programmed in the part program, ASUB or synchronized actions are
channel specifically transferred from the NC to the PLC:
•
M functions from channel 1: DB21
•
M functions from channel 2: DB22
•
etc.
The signal length is one PLC cycle.
Note
The spindle-specific M functions below are not decoded: M3, M4, M5, and M70.

Note
The M02/M30 auxiliary function output to the PLC does not state that the part program has
been terminated. In order to securely identify the end of a part program in the channel,
DB21, ... DBX33.5 (M02/M30 active)
must be evaluated. The channel status must be RESET. The auxiliary function output could
arise from an asynchronous subroutine (ASUB) or a synchronized action and has nothing to
do with the real end of the parts program in this case.
