9.1 Finding the Cause of an Error and Correcting the Error 

This chapter explains the method for troubleshooting and checking error states when using the remote 
I/O system [MEWNET-F]. 
 

9.1.1 Finding the Cause of an Error 

Follow the procedure below to find the cause of an error and eliminate it. 
 

1. Checking the LEDs 

Check the "ALARM" and "COMM." (or COM.) LEDs on the master unit, slave unit and FP I/O terminal. 

LED name 

Status 

Contents 

Actions 

ALARM 

Lights: 

Error in the unit or board. 

Replace the unit/board with a 
new one. 

Flashing 
slowly 
(1-s cycle) 

A communication error (such as 
the disconnection of transmission 
cable or the power off of slave 
station) occurs on another station.

Check the transmission line 
and location, and take a proper 
step. 

COMM. 
(COM.) 

Goes out: 

Transmission error (Error in 
transmission cables or the 
terminal station setting, 
communication with a master unit 
cannot be performed.) 

Check the error and take a 
proper step. 

 
2. Determining what kind of error has occurred 

When an error occurs, the self-diagnostic function will be activated and the type or source of the error 
will be able to be checked. 
They will be stored in teh special data registers DT9136(DT90136) and DT9137(DT90137). 
 

3. Checking the communication path (for master 1 through master 4) on which an error has 
occurred 

You can check which communication path has produced an error with the special data registers 
DT9136(DT90136) and DT9137(DT90137), and with the special internal relays R9058 to R905B.  

 
4. Checking the slave station number of the slave station where an error occurs 

You can check the slave station number in error with the special data registers DT9131(DT90131) and 
DT9135(DT90135).
