Hi all,
I have a facility run by a 1756-L61, and I want to upgrade it to an L61S with L61SP B, using the same IO modules. This is my first time performing this type of upgrade, so I'm concerned that I might run into an issue related to implementation differences between regular and GuardLogix controllers.
Pending some more research, my plan is to just update the code so that the PLC in Logix is L61S instead of L61, download it onto the controller using a test rack in my office, and then swap the controllers during the next downtime event.
Things I'm aware of that I need to look out for include:
- Setting an SNN when the L61S is plugged into the backplane where it will finally reside.
- Setting a safety task signature
- Ensuring that the GuardLogix is the CST master
Does anyone here have any experiences related to this type of upgrade that could help me catch bugs I might encounter?
Also, I've been looking around and I haven't found information about firmware revisions supported by the L61S, but RSLogix seems to only want to let me go up to 20. Do you guys know what the latest firmware revision is that I can put on that controller?
Thanks in advance!
