D.2.4 Definition of data address
The address definition of communication data is used to control VFD operations, obtain VFD state
information and set function parameters.
D.2.4.1 Rules for presentation of function code address
The parameter address occupies 2 bytes with the most significant byte (MSB) in the front and the
least significant byte (LSB) in the behind. The ranges of the MSB and LSB are: MSB—00 – ffH;
LSB—00 – ffH. The MSB is the group number before the radix point of the function code and the LSB
is the number after the radix point, but both the MSB and the LSB should be converted into hex. For
example P05.06, the group number before the radix point of the function code is 05, then the MSB of
the parameter is 05, the number after the radix point is 06, then the LSB of the parameter is 06, and
the function code address is 0506H in hex. Similarly, the parameter address of P10.01 is 0A01H.
D.2.4.2 Address description of other Modbus functions
The address definition of communication data is used to control VFD operations, obtain VFD state
information and set function parameters.
