The PROFIBUS DP interface is mainly used to connect distributed I/Os.
PROFIBUS DP allows you to create large, extended subnets, for example.
The PROFIBUS DP interface can be configured as either master or slave, and
offers a transmission speed of up to 12 Mbps.
The CPU sends its bus parameters (e.g. the baud rate) to the PROFIBUS DP
interface (if it is used as the master). A programming device, for example, can then
automatically retrieve the correct parameters and connect to a PROFIBUS subnet.
In your configuration, you can disable this bus parameter broadcast.
