Controller redundancy
Controller redundancy can be achieved by installing two AC 800F. To ensure quick and smooth takeover by the secondary AC 800F in case the primary AC 800F fails, a dedicated redundancy communications link through the second Ethernet module makes sure that both AC 800F are always synchronized. All inputs and outputs are designed to support redundant operation.

PROFIBUS line redundancy
Using the Redundancy Link Module RLM 01 will do the conversion of one simple, non-redundant PROFIBUS line into two reciprocally redundant lines. You can position the Redundancy Link Module RLM 01 directly after a PROFIBUS module (master), before a bus segment with several slaves or before an individual slave. PROFIBUS stations with redundant couplers can be directly connected to the PROFIBUS set redundant by RLM 01. Stations with only one interface can be optionally assigned to the one orother line. An alternative solution to the PROFIBUS line redundancy is to use a Fiber Optic Ring.
