Name
Indicators
LED indicators that display the Unit and network status.
Unit number switches
Two rotary switches. The unit number is set in 2-digit decimal
for the Network to which the PLC is connected.
Node address switches
Two rotary switches. The node address of the Unit on the
Controller Link Network is set in 2-digit decimal.
Baud rate switch
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
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
