Indicators (Refer to p. 51 and 287)

LED indicators that display the Unit and network status.

Unit number switches (Refer to p. 98)

Two rotary switches. The unit number is set in 2-digit decimal for the Network to which the PLC is connected.

Node address switches (Refer to p. 98)

Two rotary switches. The node address of the Unit on the Controller Link Network is set in 2-digit decimal.

Baud rate switch (Refer to p. 99)

A four-pin DIP switch. The following setting is made.

Pins 1, 2: Baud rate

Pins 3, 4: Not used (always OFF)

Terminating resistance switch (Refer to p. 99)

A slide switch. Use this switch to set the terminating resistance to ON for nodes at both ends of the Controller Link Network.

Terminal block for the communications cable (Refer to p. 66)

Terminals to connect to the Controller Link Network communications cable (twisted-pair cable).
