Downgrading GuardLogix (1756-L83ES) from v35+ to v32.011 – How painful is it?
Hey everyone,
I have a robotic cell running on a 1756-L83ES GuardLogix PLC. We want to do some virtual commissioning using a soft PLC emulator, but the emulation software requires the project to be at v35 or higher. Our actual physical hardware needs to stay on v32.011.
Because of this, I might need to downgrade our v35+ project back down to v32.011.
In the past, I had a nightmare experience trying to downgrade from v32 to v28 due to the massive changes in tag structures and string types between those versions. I’m hoping a v35 to v32 drop isn't quite as brutal since they both share the newer architecture.
Before I jump into this rabbit hole, I wanted to ask:
Has anyone done a downgrade from v35+ to v32 recently?
What specific gotchas or problems did you run into?
Any tips, horror stories, or "don't do it" warnings are highly appreciated.
Thanks!
