PLC5 SOLID RED PROC LED

[dbrsystems 0]

Hello All, I have a client that has a PLC 5/40E processor that was running but after replacing the battery the memory cleared...no biggie. Normally, this is not a big deal. I just connect, clear the faulted memory and download a new program. This time the processor will not let me connect. When I connect to Ch1A I have a GREEN Ch1A and a solid RED PROC LED. When I attempt to download the program, I get a comm error and the processor drops off the DH+ network. PROC LED stays Solid RED, all comm LEDs go off, and STAT LED starts flashing 73 or 7 then 3. Have to cycle power to get the processor back. Found the following note on RA Knowlege base: Article P78636550 Tried suggested work around but no good. Ended up finding an old copy of RSLogix and it connected and reset the memory perfectly. Loaded the program with my up-to-date RSLogix and we are running again. Just want to let everyone know that the note is not 100% accurate. Regards,
