CQM1H-series Controller Link Units

Section 4-5

Note 1. Always turn OFF the PLC’s power before setting the terminating resistance switch.

2.Turn ON the switch to connect terminating resistance at the nodes at both ends of the Network and turn OFF the switch at all other nodes. Normal communication cannot be performed in the Network unless all the nodes are set properly.

3.The TER indicator will light when the terminating resistance switch is set to ON.
