Marin Posted March 2, 2019 Report Share Posted March 2, 2019 Hi There! I am trying to read data and send data to unidrive SK inverter. As for adresses etc on unidrive side, it is all clear, because when i connect with modbus poll software via PC i can read rpm on adress 202 or start/stop drive by sending bit 0 or 1 to adress 629. I am trying to read same with visio 350-35-RA22 but i am not clear do i use right FB's........so before i'll kill myself with uploading new codes over and over could you check what i am missing? I this example i am trying to read status of adress which is 0 or 1 depending is terminal on VFD on or off. So when i press F1 which is set as SB58 i did out on display to show MB1, but, always 0....... Quote Link to comment Share on other sites More sharing options...
