■Configuration

Slot assignment: Set with the side DIP switch

Main/Sub setting: Set with the side DIP switch

Input error data: Input value setting, hold or clear, at input

module error with side DIP SW

Operation mode: Output switchable from host in duplex

communication with the side DIP SW

LED indication: Set with the side DIP

■Indicator LEDs

RUN indicator: Bi-color (red/green) LED

Green ON in normal communication; Red ON when receiving

data (Function selected with DIP SW)

ERR indicator: Bi-color (red/green) LED

Green ON or blinks at communication error (ON when

abnormal data receiving or communication setting error

(approx. 0.1 sec.))

Red ON at transmitting data (Function selected with DIP

SW)

■ RUN CONTACT OUTPUT

RUN contact: ON when RUN indicator is green (Modbus in

normal communication)
