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

 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
