Cheers!, I am an experienced electron plumber, but completely new to PLCs. I am trying to exhume a SLC500-based (AB P/N 1747-L20A) Pallet Wrapper that was left without power for several months. Although the wrapper was working great when put into storage, now when the machine is powered up, the "CPU Fault" LED on the SLC500 blinks and the wrapper is unresponsive.
I checked the backup battery (1769-BA) with a DMM and it is very flat (~0.12V). Presumably, the program that was loaded into the PLC died when the battery died. I called the manufacturer of the wrapper and they were kind enough to provide me with a copy of the RSS file (attached), but I don't have the RSLogix tools (or the budget) to upload the image to the PLC.
In reading through the threads and available literature I see that AB made EEPROM-based memory modules (e.g. 1747-M?) that can be used to load a program into the PLC. My problem is that I have an RSS image, and not a chip image file. Can anybody recommend a way to convert (compile?) the RSS into an EEPROM image? I think that if I had the image (HEX, MOT, etc), I could probably get the image burned into a chip/module. Thanks!
