CC-Link COMMUNICATION
2.3.4 I/O signal when CC-Link Ver.2 octuple setting is selected
(Pr. 544 = 118)
The device points usable in CC-Link communication are 32 input (RX) points (12
points are available for PLC function), 32 output (RY) points (12 points are available
for PLC function), 16 remote register (RWr) points and 16 remote register (RWw)
points.
