Signal list
Data block DB 76 is set up when the function is activated.
A bit is set in the appropriate group in DB 76 for an M signal decoded in the list.
At the same time, a readin disable is set in the channel in which the M function has been
output.
Activation of the function
The number of groups to be evaluated is specified in basic-program parameter
ListMGDecGrp.
The decoding function is activated if this value is between 1 and 16.
Before activation of decoding, the decoding list DB75 must be transferred to the PLC
followed by a restart.
