Re: [foxboro] OMI - operator message interface

I don't have an answer for you but you are not alone.  I have a whole bunch
of 51B's and WP30's, and plan to run them til they quit.   I discussed the
with Foxboro a 100 times and can't seem to get anywhere.

Subject: [foxboro] OMI - operator message interface


We have a rather small & antique system ... v4.3, 2x AW51B's, 1x WP51, 4x
WP30's, 2x PW-OE's ... you may be thinking "How do they keep that old stuff
running?"  Well, it's not always easy.  We are a batch plant with several
operating units, each running concurrent sequence blocks, so I need a way
to view & respond to messages from more than 1 sequence block at a time.
We use OMI (operator message interface), which works well for us.  The
problem is that each instance of OMI can only host 19 message files.  We
have one running in each 51B and in a PW-OE.  (Originally, we had 2x AP20's
which were replaced by 1x 51B, thus losing us an OMI.)  As we replace the
PW-OE's with PC-Exceed stations, we'll lose more.  Eventually we'll be left
with only 2 possible OMI hosts ... the 51B's.  Our problem is that 2 OMI's
(38 message files) is not enough.  Short of trying to keep the PW-OE's
running as OMI hosts, does anyone have a solution?  Perhaps a way of
hosting more than 19 files per station?  Or an alternative to using OMI?
I've thought of upgrading some of the WP30's to 51's, but that a very
expensive option.  (Of course, when WP30's are no longer supported, we may
have no choice ... like with our PW-OE's.)
