I have three SLC 5/03 CPUs - 2 are 1747-OS300 A2 and the other is a 1747-OS301 A8. I also have three 1747 M11 memory modules that I would like to burn ladder programs to. However, I can't get the programs burnt. Here's what I'm doing:
Tried erasing processor memory by shorting VBB & GND pads (with battery leads removed), but it didn't help.
Any suggestions?
- Downloading the program to the processor
- Go ONLINE with the processor
- Under "COMMS", select "EEPROM", then "Store to EEPROM"
