To design a redundant Profibus I/O control system with ControlLogix architecture, the SST-PFB-CLX card must be installed in a remote ControlLogix rack. In this setup, it communicates with ControlLogix CPUs via the 1756-CNB family of ControlNet bridge cards.

Although SST’s documentation explains how to set up the SST-PFB-CLX card and ControlLogix CPU to communicate through the local rack, no SST documentation describes how to use the card remotely (as required for a redundant system).

According to document 1756Soft_HBU.pdf, Application Solution “Software Output System” (Publication number 1756-AP001A-US-E), it is possible to build a ControlLogix redundant system without the 1757-SRM modules, using ladder logic to switch control between CPUs.
