Communication Profiles; Abb Drives Profile - Classic - ABB FSCA-01 Manual

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 addresses of the 32-bit parameters cannot be
accessed by using 5-digit register numbers.
