ON ON BL BL ON Communicates normally with occasional CRC errors due to noise interference.
ON ON BL BL ON Communicates normally but the Baud Rate and/or Station Address switches failed.
ERR LED blinks approximately in 0.5 seconds intervals.
ON ON BL BL OFF ----
ON ON BL OFF ON CRC error found in the received data. Unable to respond.
ON ON BL OFF OFF ----
ON ON OFF BL ON Normal communication
ON ON OFF BL OFF ----
ON ON OFF OFF ON Unable to receive data addressed to the station.
ON ON OFF OFF OFF ----
ON OFF BL BL ON Performs the interval-timed responses but CRC error found in receiving the refresh
data.
ON OFF BL BL OFF ----
ON OFF BL OFF ON CRC error found in the data addressed to the station.
ON OFF BL OFF OFF ----
ON OFF OFF BL ON Link is not started.
ON OFF OFF BL OFF ----
ON OFF OFF OFF ON No data addressed to the station. Or unable to receive data addressed to the sta-
tion due to noise interference. (Missing parts of the data sent from the master)
ON OFF OFF OFF OFF Unable to receive data due to wire breakdown
ON OFF ON OFF ON/OFF Faulty Baud Rate and/or Station Address setting
BL OFF OFF OFF OFF Blinking in approx. 0.5 Hz intervals: Input overload or no input
Blinking in approx. 2 Hz intervals: Setting error or device error
OFF OFF OFF OFF OFF Power input removed. Or power supply failure.
OFF = OFF, ON = ON, BL = Blinking
*1. SD LED may look not blinking but ON with high baud rate and fewer connected modules.
*2. LEDs indicated with “----” in STATUS rarely occurs in normal operation (LED failure or the like as possible cause).
