yeah... when I said 0.5s I meant the main cycle of CP... not 0.1s as is
allowed now with CP60. (sorry)
sure, we have most of blocks at 1s, so 2 phases to run them...
by now we are trying to reduce overruns by doing some "phasing" but just to
assure system 'till we found permanent solution.
about how many fbm for this CP... around 50 , in 3 distributed cabinets.
I/O load increased very much... twice I'ld say...
This approach (more DCM) is what local rep is aiming for now...

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,
