CQM1H-CPU21 ON FATAL ERROR 0*00E1 IO Unit Over

2 posts in this topic

Hello Professionals,

I need your kind help. I have an Omron PLC, CQM1H-CPU21 ON FATAL ERROR 0*00E1 (IO Unit Over).

The manual says, " rearrange the system to reduce the number of IO words". How do i go about these?

I have a similar CPU with same program on a similar machine, I have loaded its program and memory area data to this one on error. Error persists.

Thank you.

Is the same part number?

Can you share your I/O configuration?
