We've encountered the same issue. We've typically used one PLB block per loop,
not one per FBM (an FBM and an expander still count as one FBM). So, where we
have multiple PLB blocks we automatically get the green highlighting in SELECT.
Also, if I remember right it shows "E" instead of A for auto or M for manual,
so you can no longer see it's status from select.
On submitting a CAR on this, I've been told that multiple PLB blocks for an FBM
is not a recommended configuration. Foxboro tells me this change in PLB block
handling is by design, because if there are two PLB blocks in an FBM they both
could address the same output channels even if they don't.
Details on how this works now -- After editing a PLB block in ICC, pressing done
makes the changes. Additionally, the warning screen comes up warning about
multiple channels. At this point you can only select OK to go back to block
editing. From the block editing screen you select "cancel" to exit (if you
select "done" you just go back to the warning screen).
I agree that this is a really annoying development -- very poor way to handle
what, for many users, isn't a problem.
