Communication Profiles; Overview - ABB FSCA-01 Manual

Communication profiles

Overview

This chapter describes the communication profiles used in the
communication between the Modbus/RTU master, the FSCA-01
RS-485 Adapter Module and the drive.
Communication profiles
The communication profiles are ways of conveying control
commands (Control Word, Status Word, References and Actual
values) between the Modbus master and the drive.
You can configure the FSCA-01 RS-485 Adapter Module to
provide either the ABB Drives Profile or one of the two
Transparent modes for 16 and 32 bit words respectively. For the
ABB Drives Profile, the adapter module converts the data to the
DCU profile. For detailed information, see the drive
documentation. For the Transparent modes, no data conversion
takes place.
