• The DP master is configured and programmed.
• If the MPI/DP interface of CPU 318-2 DP is to be operated as DP interface, you
must configure the interface accordingly.
• You must program and configure CPU 31x-2 DP as a DP slave prior to
commissioning. That is, in 67(3 you must:
– "switch on" the CPU as DP slave,
– assign a PROFIBUS address to the CPU,
– assign a slave diagnostic address to the CPU,
– specify whether the DP master is an S7 DP master or another DP master,
– specify the address areas for data exchange with the DP master.
• All other DP slaves are programmed and configured.

When working on an IM 308-C or non-Siemens system, you require a device
database (GSD) file to be able to configure CPU 31x-2 DP as a DP slave in a DP
master system.
&20352),%86 as of V 4.0 includes this GSD file.
When working with an older version or another configuration tool, you can
download the GSD file at:

67(3 supports you in configuring/programming CPU 31x-2 DP. Should you
require a description of the configuration and parameter assignment frame, in order
to use a bus monitor for example, you can find it on the Internet at
