Hello Everybody.

Can somebody explain me how to read a status from a modbus device/adress.

Right now i can toggle light on/off. but i want to read a feedback, then if status is 0 the state 1 of a button is active.

I have these informations from my modbus controller.

Under review


Please specify which controller you are using?

And also send over the full table, with name of columns.
