4.4.6 Available parameters
Modbus registers (in the data model) are numbered from 1 to 65536. In a Modbus PDU (Protocol Data Unit) these
registers are addressed from 0 to 65535. This addressing model has been described in section 4.4 of [1].
The following table lists the most commonly used parameters.
