The SNS Project intends to integrate Conventional Facility Controls with its EPICS-based Accelerator Control System. EPICS will therefore be used to provide distributed high-level access to all subsystems of the SNS conventional facilities, including cooling water towers, chilled water, de-ionized water, HVAC, waste processing, and power monitoring. EPICS will provide operator displays and high-level control for more than 1000 process variables. EPICS support will be provided by three IOCs using PowerPC-based VMEbus controllers . Low-level control will be provided by Allen-Bradley ControlLogix PLCs that will communicate among themselves using ControlNet and with EPICS using EtherNet/IP [1]. . Both the PLC layer and the EPICS layer will be implemented by an industrial supplier. File server support will be Linux-based and CVS will be used to manage version control, both for EPICS and for PLC program and configuration files. All system process variable names, hardware, software, and database configuration properties will be maintained in a master Oracle database which will be used to generate and maintain EPICS and PLC databases for the entire project.
