If the UP is located at the end of a
segment for the CC-Link
communication wiring,terminating
resistors are separately needed.
These are to be prepared by users.

Up to 32 UTAdvanced series （ Modbus/RTU
slave ） controllers can be connected.
Note
Use FG as an exclusive ground. Be sure to ground using a low grounding resistance.
Modbus master wiring
