Conventional facility controls, such as those used for water and cooling systems, are often developed and operated independent of the accelerator control system using commercial SCADA systems. At the Spallation Neutron Source, these systems are fully integrated into the EPICS based machine control system to facilitate optimal machine performance. BACnet is the predominant communication protocol used in the building automation industry, thus inspiring SNS to develop a BACnet/IP software driver for EPICS to enable this integration. This paper describes how SNS uses the BACnet driver and standard EPICS tools to perform custom chiller sequencing to manage chiller system performance and meet accelerator requirements for high availability.
