5-10 I/O Link Units for CPM2C
The 8 input and 8 output points allocated to the I/O memory of the CPM1A or
CPM2A CPU Unit are allocated to the Special I/O Unit data area of the Master
CPU Unit according to the node number.
Both 8 input and 8 output points use the same node number.
For example, if the range of node numbers IN0 to IN7 and OUT0 to OUT7 is
set, and node number 0 is used, data will be input from bits 00 to 07 of word n
(Output Slave 0) and data will be output to bits 00 to 07 of word n + 4 (Input
Slave 0).
