All newer I/A series CPs (at least I know this from CP40s and up) have a hard
limit of 4000 CB-Objects per CP, this is an intended limitation of an internal
object list, not a performance or memory constraint. It has been designed this
way to limit the maximum time required in a worst case for a hot remarry of
redundant CPs. Most of the times you reach earlier other limits in a CP but if
you use large numbers of simple blocks you can easily reach that limit.
Each compound and each block occupies one place in that list. Also ECB blocks
count for that list. So 4000 tags can never be reached (as you need some list
entries for the Compounds and the ECBs. ;-) And if for any reason you need more
than one block per Tag (we have installations where this is the case, e.g. for
tagbased naming on bits which have to be extracted from words) the maximum
number of Tags is even lower.
Just to be precise.

Jack,
as far as I know you need to have a separate license for each CP and a separate
license for each FDSI that is configured for that CP, hope so because we have
purchased heaps. If you are only going to install FDSI on that particular CP
with no IO type FBM then there is a special license which covers this and is
much less expensive.
The FCP is good for 4000 the same as the ZCP and as you mentioned 2000 blocks
for the FDSI. What we have found is that it is easy have a large number of
serial data and having to use DCI blocks to interface to standard blocks makes
the problem worse. In our case all of our ex ABSTN graphics pointed to ether
MCIN or MCOUT blocks, we were unable to get graphic to look at the packed
output of the PACKIN so had to retain the MCINs. Version 8.4 has help some in
reducing this but not eliminated the DCI - Standard IA block problem.
We have now two FCPs with FDSI's only and are buying another two to do a
similar job.
We also put in 6 x 232's and directly wired to an Anybus modbus-devicenet
gateways to replace some of our ABSTN and PLC5's this has worked well.
My only gripe, and it's the old UNIX / Windoz argument is that the AB Serial
drivers don't work in UNIX we were unable to load the driver. We got round this
be configuring a dummy FDSI on a AW70, loading the FDSI then plugging it in to
the CP hosted on the SOTM machine. Not the best solution but it does work. I
still have to chase this up with Foxboro.
Regards, Rob.
