Dear Experts,
Good day:)

This is the 1st time I work with Omron PLC,
I have one machine operating with Omron sysmac cj2m cpu 31.
The PLC has error code on it's 7-segemnt : ( HE )
I checked this error code in manual and I found these information in attachment and they write check the operating environment as a correction for this error code but I do not know what they mean
can you help me please in this problem
thanks.

As the manual suggests, I would check the panel temperature, blow out the cpu to ensure no dust or shavings are present in the CPU.
Try then to power up the unit again and see if the error goes away.

Regards,
