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.
All DP slaves that conform to the standard can be connected 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.
In this case, the CPU is the DP master, which is connected to the passive slave stations or,
in stand-alone operation, to other DP masters.
Some of the devices that can be connected draw 24 V from the interface for their power
supply. This voltage is provided as non-isolated voltage at the PROFIBUS DP interface.
Connectors
Use only PROFIBUS DP bus connectors or PROFIBUS cables for connecting devices to the
PROFIBUS DP interface (
see installation manual
).
Redundant operation
The PROFIBUS DP interfaces have the same baud rate and the same operating mode in
redundant operation.

PROFINET IO interfaces (X5, X8)
Assigning an IP address
You assign an IP address to an Ethernet interface in the CPU properties using HW Config.
Download the modified configuration to the CPU. The IP address is valid for the duration of
the project.
For technical reasons, the two interfaces X5/X8 must be located in different IP subnets.
