7.4 Data address definition
This section describes the address definition of communication data. The addresses are
used for controlling the running, obtaining the status information, and setting function
parameters of the VFD.
7.4.1 Function code address format rules
The address of a function code consists of two bytes, with the high-order bit on the left
and low-order bit on the right. The high-order bit ranges from 00 to ffH, and the
low-order bit also ranges from 00 to ffH. The high-order bit is the hexadecimal form of
the group number before the dot mark, and low-order bit is that of the number behind
the dot mark. Take P05.05 as an example: The group number is 05, that is, the
high-order bit of the parameter address is the hexadecimal form of 05; and the number
behind the dot mark is 05, that is, the low-order bit is the hexadecimal form of 05.
Therefore, the function code address is 0505H in the hexadecimal form. For example,
the parameter address of P10.01 is 0A01H.
