These are the events to the best of my recollection. We were in foreign airspace below RVSM. We were cleared to an enroute fix and given an offset of 6R. As the autopilot was intercepting the offset line; we received a Level 2 FCC 2B Data Fault alert. The Captain coordinated with our Dispatcher and Maintenance as well as with ATC to coordinate an air turn back to the departure airport. We ran through all of our applicable procedures and the Captain declared an emergency. We returned for an uneventful landing and taxied to parking. My understanding is it was just a mechanical failure; so no recommendation as to how to prevent another re-occurrence.
A MD-11 EICAS alerted LEVEL 2 FCC 2B DATA FAULT so after conferring with Dispatch and Maintenance an emergency was declared while returning to the foreign departure airport.
