Table 7-1 Maintenance and inspection items 

 

Item 

Description 

Frequency 

Unit cleaning 

Turn off all the power supplies and then vacuum the interior of the 
J.NET module through the slits in its casing. Do not scatter dust 
during cleaning. 

At least twice a year 

Mechanical check 

Check J.NET module mounting screws and communication cable 
mounting screws for looseness and damage. Tighten any loose 
screws and replace any damaged ones. 

At least twice a year 

 

7.2 Replacing or adding the module 

For details about how to replace or add the J.NET module, see 

Chapter 14. Replacing or Adding Modules

 in the 

S10VE User's Manual General Description

 (manual number SEE-1-001). 

 

7.3 Troubleshooting 

As a guide for troubleshooting a J.NET module, use the indicator of the CPU module and LED indicators (ERR 

LED, TX LED, and RX LED) of the J.NET module. 

For details about how to perform troubleshooting, see
