PROFINET IO – Communication profiles
Contents of this chapter
This chapter describes the communication profiles used in the communication between the
PROFINET IO master, 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 master station and the drive.
With the FSPS-21 module, the PROFINET network may employ either the PROFIdrive
profile or the ABB Drives profile. Both are converted to the native profile (e.g., DCU or FBA)
by the adapter module. In addition, two Transparent modes – for 16-bit and 32-bit words
respectively – are available. With the Transparent modes, no data conversion takes place.
The figure below illustrates the profile selection:
