I/O signal list
5.5.1. One station is occupied (CC-Link Ver.1) (
c122
=0)
This option occupies one station area of the buffer memory of the PLC.
In the case of
c122
= 0, there are remote I/O (RX, RY both 32 bits) and the remote register
(RWw, RWr both 4 word) in the communication data for one station area.
