[foxboro] Was: Open loop alarm, now CP60 fieldbus musings

Yes, thin net, the bane of my existence.  I once thought I was rid of that 
stuff 10 years ago when the last of our VAX-hosted CAD terminals were 
hauled off; silly me.  It also was the source of most of the 
network-related problems I had with Honeywell TDC, though they had decent 
tools to figure out where the problem was.  I was nonplussed to see it on 
the CP60s.  But Foxboro is nothing if not retro ;-)

But it appears that my problems have been related to the baseplate side of 
things.  The last CP I brought up had intermittent cable problems across 
several modules and baseplates, and finally went away when I swapped a 
couple baseplates and one FBM.  The same thing is happening currently on 
the CP I just brought up; B cable errors, intermittent, on several 
FBMs/baseplates, one at a time.  I've ruled out fiber, coax, hubs, and 
FCMs; now on to baseplates and FBMs....

That looks a lot like one of my typo's :-)


We've got the 200 serries fieldbuss situation pretty much under control,
here.

Mostly by following the recomendations about not taking the thin net out
of single cabinets.
