I have a 1785-LT B PLC 5/15 processor that on power up starts up in remote program mode instead of remote run mode. The key switch is in remote. I have never seen this before, all our processors are set in remote mode and always start up in remote run mode. Any ideas? Thanks, Don.

What happens when you switch it to run mode, then cycle power?

If you have an EPROM stuck in the bottom of the processor it may be loading off the EPROM on start. In that case I think it will start in program mode.
