Fieldbus control with embedded fieldbus
258
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.
ABB Drives communication profile
Two implementations of the ABB Drives communication profile are available: ABB
Drives Full and ABB Drives Limited. The ABB Drives communication profile is active
when parameter
EFB CTRL PROFILE is set to ABB DRV FULL or ABB DRV
LIM. The Control Word and Status Word for the profile are described below.
The ABB Drives communication profiles can be used through both EXT1 and EXT2.
The Control Word commands are in effect when parameter
EXT1
EXT2 COMMANDS (whichever control location is active) is
set to COMM.
