Re: [foxboro] CP60 and FBM legacy

Running at 0.5 sec only allow one phase (0).  CP60 can hold a lot more blocks 
than the older version.  It does not mean you can run all the blocks in the CP 
in the same phase.  There is a running limit (Don't recall exactly but is about 
the same as older version CP).  Try running other blocks in a slower scan rate. 
 You must have a very special application to run all blocks in 0.5 sec.
 
Picure it as trying to pick up as many fish in a barrel witrh your bare hands.  
Even though the barrel get bigger, it does not mean you can pick up more fish 
with the same two hands.
 
Good luck!

Hey List...

We recently upgraded one of our 10 CP40A-FT to CP60FT. (well, with all net
changes required... V7.x, FO switches, etc)
We found a prob here...
CP60 new loads are very high... control loads... running at 0.5s , it's
reaching 112% and 44% (phase 0,1). Worse than our old CP40...
We used one pair of DCM to interfase new CP60 and existent legacy fieldbus
(3 remote racks, pair of PIO each)

We are working with our local reps. but not too much clues yet...

Does anybody has some hints ??

Thx. Regards,
