If you are working on an IM 308-C or third party system, you require a GSD file in
order to be able to configure the DP CPU 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 under:
• Internet URL http://www.ad.siemens.de/csi/gsd
or
• via modem from the 66&(Interface &HQWHU Fürth, Germany; Phone number

This note is applicable to CPU 31xC-2 DP, CPU 315-2 DP, and CPU 317-2 DP. If
you wish to use the CPU as a standard slave via the GSD file, then you must not
tick the Commissioning / Test mode check box under the DP interface properties
when you configure this slave CPU in STEP 7.

Commission the DP CPU as a DP slave in the PROFIBUS subnet as follows:
1. Switch on power, but hold the CPU in STOP mode.
2. First, switch on all other DP masters/slaves.
3. Now switch the CPU to RUN mode.

When the DP-CPU is switched to RUN mode, two mutually independent operating
mode transitions are executed:
