Unity Momentum processors do not have a Modbus Plus port or allow for the Modbus Plus option adapter to be used.

With the new Momentum Unity processors they do not have the capability of doing Modbus Plus. If you want to use Modbus Plus you will need the Modbus Plus Proxy TCSEGDB23F24FA. You will need one of these for every Momentum that you want to have on a Modbus Plus network.

Also, when using the PeerCop functions of the Modbus Plus Proxy, keep in mind that the Momentum CPUs add an offset of 1 to the address.
So, the address accessed in the Momentum CPU will be the address configured in the Peer Cop of the Modbus Plus Proxy +1.
