We have extended the Los Alamos Meson Physics Facility (LAMPF) control system software to allow uniform access to data and controls throughout the control system network. Two aspects of this work are discussed here. Of primary interest is the use of standard interfaces and standard messages to allow uniform and easily expandable inter-node communication. A locally designed remote procedure call protocol will be described. Of further interest is the use of distributed databases to allow maximal hardware independence in the controls software. Application programs use local partial copies of the global device description database to resolve symbolic device names.
