This manual uses the term “processor” as a general term for any of the
PLC-2 family processors. Individual processors are specified only when
some distinction must be made.
The normal operating sequence of the station processor is not changed by
a communication adapter module, that is, the processor carries out its scan
of input and output modules and execution of the user program as though
the communication adapter module weren’t there.
