Communication profiles

Contents of this chapter

This chapter describes the communication profiles used in the
communication between the Modbus/TCP client, the adapter
module and the drive.
Communication profiles
Communication profiles are ways of conveying control commands
(Control word, Status word, references and actual values) between
the Modbus client and the drive.
With the FENA adapter module, the Modbus/TCP network may
employ either the ABB Drives profile or one of two Transparent
modes for 16-bit and 32-bit words respectively. For the ABB Drives
profile, data is converted by the adapter module into the native
profile (e.g., DCU or FBA). For the Transparent modes, no data
conversion takes place.
