Hi. The data that OpenPlc expects to receive through Modbus RTU is signed (-32,768 to 32,76) or unsigned (65535)?.  Thanks

It depends on your program. If your program has an INT variable located at %IW100 for example, the data it receives is going to be interpreted as signed. In contrary, if the variable you declare is UINT then the data will be considered unsigned.
