Profibus-Dp Front Cover - Grundfos G100 Montage- Und Betriebsanleitung

Master configuration
The Profibus-DP master (e.g. PLC) must be config-
ured according to the specifications of the Profibus-
DP master in question.
Data transmission and system demands
As the DP protocol does not transmit data via
objects. Consequently, the G100 uses a superim-
posed telegram format for the DP protocol. This tele-
gram format must be implemented in the Profibus-
DP master by the system integrator.
