Implemented Functions

PA-RC2-MBS-1-LOW implements the following standard Modbus functions:
▪
3: Read Holding Registers
▪
4: Read Input Registers
▪
6: Write Single Register
▪
16: Write Multiple Registers (Despite this function is allowed, the interface does not allow to write operations
on more than 1 register with the same request, this means that length field should be always be 1 when this
function is being used in case of writing)
