PROFIBUS DP interface (X1)

Connectable devices
The PROFIBUS DP interface can be used to set up a PROFIBUS master system, or to
connect PROFIBUS I/O devices.
You can connect any standard-compliant DP slaves to the PROFIBUS DP interface.
You can connect the PROFIBUS DP I/O to the PROFIBUS DP interface in redundant or
single-channel switched configuration.
Here, the CPU represents the DP master, and is connected to the passive slave stations or,
in stand-alone operation, to other DP masters via the PROFIBUS DP fieldbus.
Various compatible devices take the 24 V supply from the interface. This voltage provided at
the PROFIBUS DP interface is non-isolated.
Connectors
Always use bus connectors for PROFIBUS DP and PROFIBUS cables to connect devices to
the PROFIBUS DP interface (
Redundant operation
In redundant operation, the PROFIBUS DP interfaces have the same baud rate.
