Profile basis
The standardized profile for circuit breakers (PI profile PI 3.122) kept by PI (PROFIBUS
International) is used as the basis for the profile.
6.3 Communication with a PROFIBUS DP class 1 master
A class 1 master is referred to as the configuring master that determines at startup the mode
in which the slave is to communicate. A class 1 master is usually a PLC, e.g. a SIMATIC S7
with PROFIBUS DP interface.
Configuration
The following configuring methods are available:
● Via a GSD file
● Via an object manager
Both configuration methods are described in detail on the pages below.
However, it is important that, regardless of the selected configuration, it is also always
possible to take up communication with DPV1, and to read or write acyclic information.
