● Operating Instructions
SIMATIC; Bus Link; Compact FF Link
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 FF addresses are set at the bus link:
– FF Link: DIP switch at coupler FDC 157-0
– Compact FF Link: DIP switch
● When using the FF Link, you can install a maximum of 2 FDC 157-0 couplers (coupler pair
in redundant mode).
