CPM1/CPM1A Memory Area Functions Section 3-2
3-2-2 IR Area
The functions of the IR area are explained below.
I/O Bits IR area bits from IR 00000 to IR 01915 are allocated to terminals on the CPU
Unit and I/O Units. They reflect the ON/OFF status of input and output signals.
Input bits begin at IR 00000, and output bits begin at IR 01000.
The following table shows which IR bits are allocated to the I/O terminals on
the CPM1 CPU Units and CPM1-20EDR I/O Unit.
The following table shows which IR bits are allocated to the I/O terminals on
the CPM1A’s CPU Units and Expansion I/O Unit.
Work Bits The work bits can be used freely within the program. They can only be used
within the program, however, and not for direct external I/O.
