Query: Integrating Externally Developed Systems For SNS Linac Cooling And
  Vacuum   External contractors are developing the local cooling and vacuum control
systems for the Spallation Neutron Source (SNS) linac. Soon these systems will
be integrated into the facility-wide controls system. Allen-Bradley Logix5000
series programmable controllers, populated with appropriate input/output
modules, were selected as the local controllers. These controllers will be
interfaced to the facility-wide control system via VME systems with PowerPC
processors running the Wind River VxWorks operating system and Experimental
Physics and Industrial Control System (EPICS) front-end controller software.
This paper describes the interface and integration issues driven by project,
cooling system and vacuum system requirements and hardware selections.
