Carolina,

Try the following:

  • try addressing the next register:[Modbus1]HR17 instead. See if you get a good value. If you do, you may be need to check if the device is using 1-based or 0-based addressing and change the connection settings accordingly
  • see if there is a unit ID other than 0. For example, for a unitID of 1, the address should be "[Modbus1]1.HR16
  • I see you are using Serial RTU - is that what you intend to use? (Or is it RTU over TCP, or just simply Modbus TCP?)
  • See if there are any errors in the Gateway console related to your Modbus connection. If so, what are they?
