Configuring underlying DP slaves

The underlying DP slaves are configured in STEP 7.
Step
1 If you have not yet done so, start STEP 7 and open your SIMATIC H station in
HW Config.
2 If the required DP slaves are not directly configurable (see Appendix C), import
the corresponding device master files using the Extras > Install new GSD
menu command.
Result: The DP slaves appears in the
PROFIBUS-DP\Additional field devices directory in the hardware catalog
3 Drag the required DP slaves from the
PROFIBUS-DP subdirectories in the hardware catalog to the underlying DP
master system.
4 Configure the DP slaves with STEP 7.
When the underlying DP slaves are configured, HW Config checks that the
quantity structure is adhered to and outputs an error message if the permitted
quantities are exceeded.
PROFIBUS address of the IM 157 in the underlying DP master system
In the underlying DP master system, the two IM 157 modules use addresses 1 and
2. In addition, address 125 is blocked for DP slaves. The first possible address for
an underlying DP slave is 3.
Editing the DP slaves in the user program
The process data of the DP slaves should only be accessed in the user program
through the process images.
