7.1 Configuring the IM 151-7 CPU
Configure the interface module IM 151-7 CPU as the following:
I slave
I slave and DP master
Stand-alone module (MPI)
Stand-alone module (MPI) and DP master
The IM 151-7 CPU is presented to the user in STEP 7 as an S7-300 module that is
always created together with a rack in an S7-300 station. Similarly, the module can
only be deleted with the rack!
Expansion racks cannot be configured in an S7-300 station that contains an
IM 151-7 CPU. The IM 151-7 CPU is positioned at slot 2 and receives an MPI/DP
submodule. The first plug-in modules can be configured as of slot 4.
The following configuration options are available:

Stand-alone (MPI)
IM 151-7 CPU as S7 slave
STEP 7 (HWConfig)
V5.2 or higher + SP1
IM 151-7 CPU with the DP
master module as the DP master
SIMATIC S5 COM PROFIBUS Fully configured and programmed
IM 151-7 CPU, integrated as a
standard intelligent slave via GSD
in COM PROFIBUS
Non-Siemens
systems
Non-Siemens tool Fully configured and programmed
IM 151-7 CPU, integrated as a
standard intelligent slave via GSD
in a non-Siemens tool
Note
If you wish to operate the IM 151-7 CPU as a standard I slave via the GSD file,
then you should not activate the commissioning/test mode checkbox in the DP
interface properties when configuring this slave CPU in STEP 7.
Information on configuring the DP master functionality is provided in Chapter 6.2.
