How to configure the redundant PROFIBUS PA

Introduction
The following is a description of how to configure a redundant PROFIBUS PA that is connected
to a redundant PROFIBUS DP.
You can find configuration variants in the section "Fault-tolerant PROFIBUS PA (Page 74)".
Requirements
● The PCS 7 project with a SIMATIC H station is open in SIMATIC Manager.
● Two DP master systems are configured for the SIMATIC H station in HW Config and these
are used as connection paths for the redundant interface.
● For commissioning: The PROFIBUS addresses are set with the DIL switches on the
FDC 157-0 DP/PA couplers.
● You can install a maximum of 5 FDC 157-0 DP/PA couplers, one coupler pair of which is
used at the end of the configuration in redundant mode.
