Q:
I'm connecting a UT with CC-Link communication to another downstream UT via RS485 communication (Modbus master function). However, the RS485 communication terminal of the UT with CC-Link communication is a 2-wire system, and that of the other is a 4-wire system. How should I make the connection in this case?
A:
Wire the UTs to each other using a 2-wire system. For the 4-wire system terminals, short SDB(+) and RDB(+), and SDA(-) and RDA(-).
