Commissioning the DP/PA link
Step Activity
1 Configure the DP/PA link.
2 Set the PROFIBUS address of the IM 157.
3 Switch on the power supply for the DP/PA link.
4 Load the configuration into the target system.
Configuring the DP/PA link
The DP/PA link is configured with STEP 7 for S7 standard operation and for
redundant operation.
For the DP standard master operation, the DP/PA link is configured via the
device master file, e.g. with COM PROFIBUS.
The DP/PA couplers are gateways between the S7 backplane bus of the IM 157
and PROFIBUS-PA with the PA field devices. Therefore, the DP/PA coupler does
not have to be configured.
