Hi all.
I do a lot of fault finding but not a huge amount of programming with the plc's. My question relates to the AB SLC500. I need to simply add a Ex If Open type contact to an existing running PLC. Can I do this LIVE or do I have to do it offline and upload the complete program again?
The unit is on a running machine and I dont want to take it offline as I do the upload so I either have to do it live (if possible) or when the machine isnt being used.
Many thanks
