(a) Checking for failure of the head module

1.

Selecting the head module in "System Monitor" and 

clicking the 

 button will open the "PLC 

Diagnostics" window.

2.

Select the error that is occurring, and click the 

 button to check the cause and action.

When data link cannot be performed even though no 
failure is shown in "PLC Diagnostics", open the 
SSCNET III Communication Condition Monitor window 
of MT Developer2 and take action. (

 Page 77, 

CHAPTER 9)

3.

Reset of the head module and errors occurred 

before power off can be checked in the "Error 
History" window.

[Diagnostics] 

 [System Monitor] 

 

 button

In the single "Error History" window, the error history of 
the head module and intelligent function modules can 
be viewed. (

 Page 87, Section 11.3)

4.

If data link is not available even after 

troubleshooting by the above operation, perform 
the following.

• Checking with SSCNET III Communication Condition 

Monitor by connecting MT Developer2 to the Motion 
controller (

 Page 77, CHAPTER 9)

• Checking the LEDs (

 Page 89, Section 11.4)

• Troubleshooting by Symptom (
