NC/PLC interface (DB 10...DB 25)
3.6.1
Channel-specific signals
Interface data blocks DB 10 to DB 25 are assigned to NC channels 1 to 16. The PLC that is to
process the NC must be specified in machine data MD 6000 - 6001 and MD 6100 - 6101, for
PLC I and PLC II respectively.
Note:
On GA2, software version 1 and higher, you can only select up to eight channels out of 16
because no more than two NC CPUs can be used.
