Communication object vs. Register
All the data intended for communication has its representation as communication objects in the controller. The
communication object is represented by the n-byte array in the controller memory and identified by the unique
16-bit communication object number. The register, according to Modbus communication protocol, represents a
two-byte data and in communication functions is referenced by 16-bit register address. Further in the description
