The Super Conducting (SC) Linac Coherent Light Source II (LCLS-II) facility at SLAC is capable of delivering an electron beam at a fast rate of up to 1MHz. The high-rate necessitates the processing algorithms and data exchanges with other high-rate systems to be implemented with FPGA technology. For LCLS-II, SLAC has deployed a common platform solution (hardware, firmware, software) which is used by timing, machine protection and diagnostics systems. The wire scanner diagnostic system uses this solution to acquire beam synchronous time-stamped readings, of wire scanner position and beam loss during the scan, for each individual bunch. This paper explores the software architecture and control system integration for LCLS-II wire scanners using the common platform solution.
