Is there anything connected to the peripheral port or the RS232 port? Even just the cable?

Crooked pins ?

Omron Startup Mode

If you can get online, ensure that the PLC Setup, Startup option, is set to "RUN" or "MONITOR", not "Programming Device".

If it's set to the latter, and if you've something like a CIF01 plugged into the periph port, when you power up, the PLC starts in PROGRAM mode.

I believe that the "comm" led is lit if any programming device (laptop, etc.)is plugged in, or if you have any serial device (touchscreen, etc.) plugged in.
For the "run" LED to be on the PLC needs to be either in run or monitor mode. I think Omron calls it the "operating mode". If your using CX Programmer, go under the "PLC" pull-down menu to change it's setting.

OR...

CTRL + 1 is Program Mode
CTRL + 3 is Monitor Mode
CTRL + 4 is Run Mode
