What are the Run, OK, and I/O indicators doing? What is your online status? What position is your key switch in?
I think the BAT indicator being grey means there is no trouble there.
The program can be Uploaded in any key position this is what the documentation say however I tried in all three positions and the same thing happen
Run goes to green if turned to Run Mode
I/O indicator goes green then goes grey I have attached a video
When I try to go online it does its thing and then fails to go to the online state
