Data Acquisition Software for the LAMPF Control System

As part of the upgrade of the Los Alamos Meson Physics Facility (LAMPF) control computer, the software providing the interface between application programs and the accelerator hardware was redesigned. This new Data System design - which handles more than 12,000 widely different devices - allows greater uniformity, flexibility, maintainability, and hardware independence than before. The Data System portion of the LAMPF Control System is described in this paper.
