The FCMs are specified in the special marker area as follows:
- SM16.0 .. SM17.7 single FCM;
these FCMs are reset by the system
after the coordinated command
has been implemented;
- SM18.0 .. SM19.7 permanent FCMs;
are not reset by the system after the
coordinated command has been
implemented;
The FCMs are coded as follows:
SM16.0 .. SM 17.7 ---------> FCM 0 H .. F H
SM18.0 .. SM 19.7 ---------> FCM 10 H .. 1F H
