Controls and the AFT Tool

This paper summarises accelerator Controls and the Accelerator Fault Tracking (AFT) tool for LHC during Run 2. Concerning Controls, the performance and evolution will be covered, with a particular focus on the so-called "Smooth Upgrades" process. Subsequently, the major changes linked with Long Shutdown 2 (LS2) will be described, including End-Of-Life, changes to the GUI strategy, and the introduction of the new Logging system-NXCALS. Finally, re-commissioning considerations and the outlook for Run 3 will be covered. The AFT tool will be described in terms of what value it brought during Run 2, and in what direction it should, or could evolve going forwards.
