Hello Georgee the best advise I can give you is to start by having a look at chapter 11 of the SIMATIC Fault-tolerant systems S7-400H manual. I hope this helps |

You'll need 4 CP443-1 cards, 1 for each processor and redundant wiring between each pair (0 pair and 1 pair) |

If there is only one CP on each rack it removes redundant communication and removes all communication if a CP card becomes faulty. |

If it is just for information exchange you can use a y-link and connect a dp-dp coupler for communication between the two systems. |
