MODBUS Read & Write Bites from Control Word


Recommended Posts

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.
