OK so I mad a mistake. It's only the second one ever.
Actually it is a MG30 and here is another mistake. There are actually 22
devices hanging on that gateway.
What I actually tried to do during our FAT was upgrade the MG30's to style 'D'.
My request was rejected.

18 devices in an Modbus Gateway! Are you sure? (Dumb, question I admit.)
Maybe in a Modbus Integrator. In fact, didn't you take all of your GWs out
and replace them with DIs?

Unfortunately someone in the Houston office configured one for us
with 18 devices. However, it does work.

It is in the manual, but...
The Modbus Gateway (and the newer DI I'm pretty sure) can address 8
=
PLCs and
no more.
The CmP-15 is about the same capability as a CP-10. A CP-10 could =
crunch
about 150 Blocks/second.
The bigger limitation than blocks tended to be I/O bandwidth. It
could
handle about 128 bytes/second (64 registers per second).
Hope this helps.
