Need help connecting a Modbus Gateway to an Inhand-router.

Need help connecting a Modbus Gateway to an Inhand-router.

I need to be able to listen to Modbus device and calibrate it from a remote location. I need to be able to send requests on and expect responses from any register on the device, not just the registers I uploaded to send responses from the device.

Sorry if my request sounds like a tall order, but any feedback or support will be much appreciated.

Kind regards,
Karl
