The SAPHIR GModBus Over Serial Line Toolkit is a LabVIEW add-on that enables serial communications for your LabVIEW applications using the Modbus protocol. Fully integrated with LabVIEW, it provides tools to quickly test communication with a Modbus slave before coding with LabVIEW. You can use the slave simulator to develop without the real device connected. This feature makes code development and maintenance easier.

With minimal Modbus protocol knowledge, you can make your application communicate on a Modbus network. And LabVIEW Real-Time compatibility helps your code run on a real-time target without modifications.
