6-1 Allocation of Input Bits and Output
Bits
This section describes the allocation of input bits and output bits.
OMRON calls allocating I/O bits in memory “I/O allocation.”
The I/O on Expansion I/O Units are allocated I/O bits in the words following the allocated words to the
built-in I/O on the CPU Units.
