I'm developing a Web application with HMI capabilities that needs to interface with multiple Modbus RTU and Modbus TCP PLCs:

  • frequently update the web UI based on the state of the Modbus devices
  • send commands to Modbus devices based on the user's input

What is the best way to integrate a Web application and a bunch of Modbus devices, given the requirements?

have you looked at modbus bridges (or Modbus-RTU to Modbus-TCP converters)? and the 'middle-man' software we use at our place is Kepware which then talks to our SCADA package (Cimplicity for us). Not sure if you're still in need of any more info on this, just shout back and i'll fill you in a lot more :) Also, does this need to be a low cost solution (you could pretty much do this with off the shelf hobby hardware) or a full-blown industrial solution? Doing a dead simple SCADA bit and then talking to the plc's shouldn't pose too much of a headache if you have the time for it.
