EVLA Monitor & Control Transition System

Software

Overview


2

Contents

• Presentation roughly follows the EVLA M&C Software Design document:– Scope of the M&C System– EVLA M&C Components – Transition System & Final System– Lifespan of the Transition System– Carryover from Transition System to Final System – Current State of the Transition System– Architecture & Dataflow– Selected Components


3

Definitions

• The EVLA M & C Transition System Software is the software designed and implemented for the purpose of operating the hybrid array.

• The hybrid array is the VLA up to that point where it no longer contains either unconverted VLA antennas or the VLA correlator.

A Transition System and

A 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 variety 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


8

Lifespan of the Transition System

• First light on an EVLA antenna – 27Oct 2003• First fringes (EVLA ant 13 with an unmodified VLA

antenna) – 24 Mar2004• WIDAR correlator scheduled to be operational – Q1 2010• VLA correlator retired – a policy decision• VLA antennas no longer used – also a policy decision.

The last VLA antenna is scheduled to be converted to EVLA electronics in Q3 2010

• Last EVLA receiver installed – Q2 2012

Normal operations

•A job is submitted via the SCRIPTS pane of the Array Operator Screen

•Either a VLA Observe file or a control script can be submitted

• Observe files are automatically routed through obs2script & converted to control scripts• Needed observing parameters are obtained form the Parameters database• The Interim Observation Executor directly configures

– EVLA antennas– VLA Antennas (soon)– The VLA correlator via the new correlator controller (soon)

MIB Hardware & Software

• EVLA antennas are presented as a collection of modules containing one or more devices, each module implementing the MIB interface

• MIB interface includes a command port, a data port, and a port used for interactive telnet sessions

• The final version of an EVLA antenna is expected to contain approximately 30 to 34 MIBs

• MIB hardware and software were subjected to a critical design review on 20Oct2004

VLA Antennas – the CMP

• The CMP presents VLA antennas to the EVLA M & C System as virtual antennas implementing the MIB interface

• The VLA antenna MIB interface includes the same command, data, and telnet ports as the EVLA module MIB interface

• Uses the same basic “set <device> …” & “get <device> …” command format as is used for EVLA subsystems

• Interfaces to the VLA Serial Line Controller

AntsolPointingFocusDelays

• Properly formatted visibility data flows from the array processor into the Visibility Pipe via an ISA bus interface on a card in the new correlator controller• The visibility data is transmitted from the Visibility Pipe to IDCAF over an Ethernet connection using TCP/IP• IDCAF collects meta-data & alerts via multicast and forms VLA format archive records• IDCAF flags the records as needed• IDCAF multicasts the archive records and writes them to a staging disk• ITelCal obtains the archive records from the staging disk

Critical Functions

• Will allow an E-Stop, ACU Reset, Critical Power Reset, Track (DPM), Stow, Park, or Standby command to be sent to any antenna, selected group of antennas, or to the entire array.

• Depends upon the installation of the M302 module in an antenna

Critical Functions Screen

28

Module Screens

• ACU – antenna control unit• FRM – focus & rotation module• F317 – front end (rcvr) controller• F320 – front end transition module• L301 – 12-20 GHz synthesizer• M302 – Utility module, includes critical
