the AC500 redudancy can be achieved by using a cable, High Availability library. Using the CS31 bus. Thats it.

If you are talking about hot redundancy, Abb suggests one use PM58x and above cpus.To achieve controller redundancy, a high availability module such as ci590 cs31 ha is required to interface the controllers in a redundant configuration.in addition to the above hardware, HA library functional blocks namely, cs31_HA CONTROL, DATA_SYNC and callback_stop are essential.
