The LCLS Machine Protection System (MPS) contains thousands of inputs and hundreds of protection interlocks. The inputs and logic configuration are defined in SQLite database files. Real-time state information is hosted by EPICS signals. Control room operators use a Graphical User Interface (MPSGUI) to view and manage faults. The MPSGUI provides a wealth of useful information, from hardware input details to high-level logic flow, but it was difficult for operators to take advantage of this. The workflow required cross-referencing between several screens. This poster presents the greatly improved workflow and usability of the MPSGUI. The requested improvements were defined in meetings between the MPS controls team and the control room operators. The improved GUI allow operators to more quickly respond to MPS faults and diagnose problems reducing troubleshooting time by 20 percent.
