  • P-2000 550 to SCADA system with Modbus

    I am trying to find out how to set the Modbus node address for the P-2k. I am using Ethernet and will have multiple P-2ks as slaves to the SCADA system. The help files dont reference this.

    You set the IP address in the CPU setup of the Hardware Configuration. If you are talking about the Unit ID number embedded within the Modbus TCP header: the P2-550 does not require a specific value for this field. It will simply echo back the same value sent in the request (which is the proper behavior for a non-gateway Modbus TCP device).

      Jackson, Thanks for the reply. You were right it works very well. Tested it this morning and the data is passing both ways like it should. I guess the IP address is what the Modbus uses. It works well from Mango using the "Modbus IP" drive as the data source. Again thanks for the help.
