■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)
