Control And Configuration Capabilities; Figure 7-2: Sample .Net Gui For Modbus Tcp Access To 922-Dslh - Focal 922-DSLH User Manual

TM
Focal 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 922-DSLH Modbus functionality. Typically
users have or develop their own Modbus TCP interfaces for local PLCs and other controllers. A screenshot of
the sample GUI P/N: 922-0414-00 is shown in the figure below.
