Transition System vs.
Final System
• In broad terms, there will be two major versions of the EVLA Monitor & Control System – a Transition System and a Final System
• The Transition System bridges the gap between the old Modcomp-based VLA Control System and the final version of the EVLA Monitor & Control System, while maintaining operational capabilities
• The Transition System will be responsible for controlling a wide array of old and new hardware – EVLA Antennas, VLA Antennas, the VLA Correlator, and the prototype WIDAR correlator
• The Transition System will incrementally shift its software architecture toward the desired architecture of the final system

Selected Transition System Milestones
Support for EVLA antenna hardware development Use of EVLA Antennas in scientific observations
– Monitor and control of EVLA antennas• Retirement of the Modcomp-based VLA control
system– Monitor and control of VLA antennas (nearly done)– Monitor and control of VLA correlator– Distribution of VLA correlator output within EVLA M&C– Formation & writing of VLA format archive records
• Support WIDAR prototype correlator• Implement target architecture of final system
