Hiya,
We are rebuilding a plant where some MCCs were destroyed in a fire. In order to get back into production asap we decided to go profibus (simocode) on all the drives. This necessitated a switch from the oldish A3A CPU to the latest Q25 CPU ( 7 PLCs total).
What concerns me is that the Mitsubishi PLC profibus cards (Q71PB92D) can only handle 30 nodes "due to card memory". I am accustomed to 32 nodes per profibus DP master and based on the fact that we are installing 76 optical link modules (to give you an idea of the network size) - should I be concerned with the ability of this Japanese PLC to handle Profibus? Any field experience out there?
TIA
