Modbus TCP Commands and Parameters
The HI 6500 instrument will automatically detect and connect to any available Modbus
TCP connection. The system will show either connected or not connected to display the
availability of a Modbus TCP connection.
The Modbus TCP and Modbus RTU Diagnostics screen may help with troubleshooting
connection problems with the HI 6500 series units.
The Modbus Diagnostics parameters count the number of frames received by the Hardy
6500 unit and how many of these are valid compared to error frames. In this case, the unit
is correctly reporting that it is not connected and is not receiving any frames.
