6.2 Features of the SEW DP-V1 interfaces

The SEW fieldbus interfaces to PROFIBUS DP-V1 have the same communication

features as the DP-V1 interface. The MOVI-PLC

advanced DHF41B control card is

controlled via a C1 master with cyclical process data in accordance with the DP-V1

standard. This C1 master (usually a PLC) can also use an 8-byte MOVILINK

parameter

channel during cyclical data exchange to execute the parameter services with the

MOVI-PLC

advanced DHF41B control card. The read and write services allow the C1

master access to connected stations via the DP-V1 C1 channel.

Parallel to these two parameter channels, a further two C2 channels can be set up. For

example, the first C2 master (visualization) could use these channels to read parameter

data, and a second C2 master (notebook) could use them to configure the MOVI-PLC

advanced DHF41B control card using the MOVITOOLS

software.
