    "abstract": "External contractors are developing the local cooling and vacuum control\nsystems for the Spallation Neutron Source (SNS) linac. Soon these systems will\nbe integrated into the facility-wide controls system. Allen-Bradley Logix5000\nseries programmable controllers, populated with appropriate input/output\nmodules, were selected as the local controllers. These controllers will be\ninterfaced to the facility-wide control system via VME systems with PowerPC\nprocessors running the Wind River VxWorks operating system and Experimental\nPhysics and Industrial Control System (EPICS) front-end controller software.\nThis paper describes the interface and integration issues driven by project,\ncooling system and vacuum system requirements and hardware selections.",
