Ben Posted March 6, 2020 Share Posted March 6, 2020 Hi, I am really new to using MODBUS. I have managed to setup the comms. I can read and write some data from/toUntitled1.pdf a WEG VFD. Such as speed and voltage. However to control the VFD it uses a Control Word. (PDF explanation attached) Can somebody help me display the Control Words bit status's in a table and create buttons to change individual bits. Any help would be appreciated.
