It is absolutely necessary that either the input "CMODINI" or the input " EN_OM" is set.
This also applies for the inputs "SCT" and "SGC".
It is also important that the inputs "OM_BY_LI" and "LM_BY_LI" are only set or reset by pulses. A permanent 1 signal is not permissible.
The inputs "T_OPRQCA" and "S_ERRCA" may also only be acknowledged as pulses after occurrence of an error.
Only one command can be set (START, STOP, ABORT, RESTART).
For working through the SFC steps it is important that the input INSTOUT is set, otherwise no commands are output.
