Support multiple Modbus devices on the same machine

Add support for multiple Modbus devices (using the same IP address but different port numbers) on the same machine. For example, the interface could allow the user to configure something like this: /dn= xxx.xx.xxx.xx:43120,/cn=1,/polldelay=0,/to=2,/rci=30,/writedelay=0,/debug=0,/disabled=0 /dn= xxx.xx.xxx.xx:43122,/cn=1,/polldelay=0,/to=2,/rci=30,/writedelay=0,/debug=0,/disabled=0 /dn= xxx.xx.xxx.xx:43124,/cn=1,/polldelay=0,/to=2,/rci=30,/writedelay=0,/debug=0,/disabled=0   Note: This was previously Enhancement 121980.

    While we are declining to add this functionality to the PI Interface for Modbus Ethernet PLC, the PI Adapter for Modbus TCP does support the configuration of Modbus devices with the same IP address and a unique port number. We encourage you to go to the PI Adapters forum to share your use cases.

    Hi Chris, do you know approximately when we can expect the release that would include this improvement?

    We have the same case. As workaround we configured several instances of PI ModBus interface. But this seriously increased amount of mouseclicks to configure that.

    We have the same issue with PI implementation for transmission monitors. It will be difficult to manage multiple instances for each port with same IP address. if we can use IP/port combination in the InstrumentTag for PI Points, it will help solve the problem we see.
