Communication profiles
Modbus is an application layer messaging protocol. It describes
how data is transferred between a master and a slave, but not the
meaning of the data. Communication profiles define the meaning
of the data.
ABB Drives Profile - Classic
The ABB Drives Profile - Classic communication profile provides
register mapped access to the Control, Status, Reference and
Actual values of the ABB Drives Profile in the classic format for
backward compatibility.
* 6-digit register addressing (400001) is used instead of 5-digit
register addressing (40001) to describe register map. See section
Register addressing for additional information.
** Register addresses of the 32-bit parameters cannot be
accessed by using 5-digit register numbers.

400101-409999 Drive Parameter Access (16-bit)
Register Address = 100 x Group + Index
Example for Drive Parameter 3.18
100 x 3 + 18 = 400318
Register addressing of the 32-bit parameters (not
supported with ACS350):
200 x Group + 2 x Index
Example for Drive Parameter 1.27
200 x 1 + 2 x 27 = 420254
