Moog has created a sample version of a .NET graphical user interface (GUI) for use on Microsoft Windows with
a Modbus TCP backend for integration and bench testing the Model 920 Modbus functionality. Typically users
have or develop their own Modbus TCP interfaces for local PLCs and other controllers. A screenshot of the
sample GUI is shown below in Figure 13.
