I have a question regarding C-Net topology and device number limits.
At the moment, I am counting the number of "connections" (not sure of the correct term) on each 1756-CNBR in our C-Net system (we have 3 networks).
I am to tally the number of connections from all the 1794-ACNRs under each bridge, and their repsective IO:
-All AI / AO modules count as 1 connection.
-All DI / DO modules are rack optimized, so any and all DI/DO modules on an ACNR are considered 1 connection, together.
-Add 1 connection for the ANCR itself.
-We are tieing in D-Net, so CN2DN modules count as 1 connection.
Am I correct in understanding that per network there can only be a max of 99 connections, after which another CNBR card is needed?
What would happen if the digitial modules were not rack optimized (would each card count as a connection)? I know this enables the status info to be sent, but no one has broken down for me how this affects the connections count.
Thanks
