Process alarm

A process alarm causes a call of the OB 40. Within the OB 40 you have the possibility of
determining the logic basic address of the module that has triggered the process alarm via
the local word 6. Further information on the triggering event can be found in the "Local
double word 8".

stored as 16−bit

ms value together with the count value in the input area.
