L32E firmware / software versions

I have an L32E processor that is currently using RS Logix 20.01 software.

It's been a while since I've touched Allen Bradley software, so before I go in the field and screw myself over, I thought I'd look for advice.

I'd like to update the firmware / software version so it will save tags/comments/etc. Is there a danger here? I seem to recall versions around 20/21 not playing very nice with any other higher versions.

If I "update" the firmware, is there a way to roll everything back?

Nothing fancy on this machine, just the processor with AB I/O modules and a panelview plus screen.

Thanks!

I'm not sure the L32E will go higher than 20.01. You need to check AB's compatibility web site.

No, version V20 is the highest version you can handle with this model L32E.
L3XER or L3XERM are the new models, they can go up to V32 so far.

Got it.

That's what I was worried about.

I'll double check the compatibility web site.

Thanks all!
