  1. 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.
