Hello everyone,

I am currently trying to connect and control a Daikin VRV central air conditioning system via the DTA116A51 board using the Modbus protocol. However, I am unable to read or write 3 or 8 bits... from the 16-bit Holding Register or Input Register to bOS. Do you have any solutions to this problem? Please help me.

Hey

You should use bit converter. For the fan direction try to use bit decoder start bit 8 and end 10 bit.
