2-3-2 Input Interrupts
The 10-pt CPU Units (CPM1-10CDR-
and CPM1A-10CDR-
) have two inter-
rupt inputs (00003 and 00004).
The 20-, 30-, and 40-pt CPU Units (CPM1-20CDR-
, CPM1A-20CDR-
,
CPM1-30CDR-
(-V1), CPM1A-30CDR-
and CPM1A-40CDR-
) have
four interrupt inputs (00003 to 00006).
There are two modes for input interrupts: input interrupt mode and counter
mode.
