Figure 2-13 M decoding acc. to list

Activation of the function

The number of groups to be evaluated/decoded is indicated in the basic program parameter

"ListMDecGrp" when FB 1 is called in OB 100 (see also FB 1 description). M decoding is

activated if this value is between 1 and 16. Before the function is activated, the decoding list

DB75 must be transferred to the PLC followed by a restart.
