Greetings,
I purchased a firmware update for our PLC-5/L60B.
After installation the CH-1A LED is supposed to be blinking green, according to the instructions. Well.. it would not blink red or green or yellow. Nothing on any channel lighting up at all. After 3 hours of pulling hair, I had to install the old firmware. Powers up and runs fine with old chips inside. Just wondering if there was maybe something I could do to make it work short of sending it back. Just so you know, I double checked the chips for correct orientation and placement.
Funny thing happened though. With new firmware in place I tried to download the program file even though the light would not blink. A screen popped up asking me if I wanted to change the processor type to REV "R" and resize the data tables. I clicked "Yes" and no comms after that. Curious as to how the RSLogix5 software knew the revision was different if there was no communication at that time. Strange! I probably should have changed the revision setting in the controller properties page, saved the file first before attempting the download. Anyone have experience with this before?
Tony
