Re: [foxboro] FBM232 and AB ControLogix

I seemed to have confused things a bit with my DI270 reference.

What I was trying to say is that a FCP270 on a base plate with an FDSI
FBM is the equivalent under V8 of the DI30 though it is lots bigger and
faster.

An FCP270-FT on a base plate with a pair of redundant FDSI FBMs (4 FBMs
total) gives you about 4000 tags from the 3rd party device.

The idea behind the CP/FDSI combination is that you minimize your spare
parts and get the performance of separate processors for communications
and control.

Sorry if I sent you off looking for a new control station!

PS. I recognize that the conversion of an existing DI15/30 to CP270/FDSI
combination is non-trivial. That's a different topic of conversation.

The limit on tags/registers in the FDSI FBM is 2000. It is fixed.

The limit on control blocks in a CP is 4000.

With V8.4 and later the DCI blocks have alarming so you can about 4000
tags/registers into a CP using two FDSIs.

The DI30 replacement should be the DI270. The DI270 is "ta-da" a
CP270/FDSI combination. Using an FCP and the right baseplates makes a
nice gateway station.

Of course, you can add other I/O as well depending on loading.

I think its 2000 tags/FBM23x and 4000 points ZCP270. By the way, the
4000 points in a ZCP270 is hard-coded. ICC will not let you add more
than 4000 points/ZCP270. I do not believe that the 2000 tags/FBM23x is
not hard-coded.

Here's a ringing customer endorsement, (OK ringing might be a little 
strong and I'm not a customer but an integrator, close enough.)

1) The FBM232 supports ethernet/IP communications with the CLX based on
tags.
    Supports up to 4000 tags ( I think that's right)
2) It is really fast compared to the old serial KF2 or KFC style 
communications.
3) It is pretty robust.  *There were some problems early on, but they 
work pretty much as advertised these days.
4) Fault tolerant comms work (but be sure to check configuration and
test)

The only drawbacks we have seen with these are the lack of support 
for User Defined Types {UDTs] in tags, and some of the old tricks 
like mapping one memory location to multiple tags.

Also it would have been nice if the PAKINs had individually 
accessible bits for use on displays like MCINs.  Either you can 
bitmask every bit you wish to display, or map the PAKIN to an MCIN to 
show them on Foxview.   (ICC conections are not affected since they 
support the C:B.P.B1...B32 extensions.)

Overall a nice product and one we use a lot.

Regards,
David
