Communication profiles

The embedded fieldbus supports three communication profiles:
• DCU communication profile
• ABB Drives Limited communication profile
• ABB Drives Full communication profile.
The DCU profile extends the control and status interface to 32 bits, and is the
internal interface between the main drive application and the embedded fieldbus
environment. The ABB Drives Limited is based on the PROFIBUS interface. ABB
Drives Full profile supports two Control Word bits not supported by the ABB DRV
LIM implementation.
