Add a Modbus Slave on AC450 with CI534V02?
I have an Advant system with CI534V02 Modbus MVI boards installed in AC450. In this case the AC450 is configured as master on the Modbus.
Is it not possible to add a new Modbus slave node without restarting the controller? There does not seem to be any note about this in the manuals. I can create a new node (MVINODE) without any system messages being posted, but it seems that the controller does not recognize this new slave and makes no attempt to communicate with it (I am expecting the CI534 to at least send a function code 08 poll to this slave).
The Modbus is working fine with the existing slaves on each port, only the added slaves are not working. Cycling :IMPL and/or :SERVICE on the MVI object does not bring these slaves to life.
Am I trying to do something that cannot be done? Is there any documentation about this limitation? Any tips would be much appreciated. Doing a cold start on my controller is really not an option.
