@Bl00d_b0b

any help, how i can transform from int16 to boolean, and read/write?

Did you see this? It is a linked thread, if you click on it there is more detail.

Bitwise operations in a modbus register

I’ve covered this before, but it got a bit lost in a general thread. @kazemiprince flushed out my errors, thankyou so we can present a tested solution here. Problem There are few “rules” in Modbus, each manufacturer decides their own way how to present device data and controls. Even though Modbus provides ‘discrete’ inputs and ‘coil’ outputs for binary controls, such as go/nogo limit switches or on/off relays, sometimes a designer opts to present binary values as individual bits pack…

I am prepared to help you with this, but I’m not going to write it all for you.
Please have a try at reading that status register into openHAB Items, and let us know how you get on. We will help. This is complicated, but if we go step by step there is a path to make it work.
