This document outlines the discussions from the EVLA Monitor & Control (M&C) Advisory Committee meeting held on September 8-9, 2003. Key topics include software requirements produced by the NRAO user community, MIB configurations, and the quality and testing of MIB software crucial for EVLA operations. The meeting emphasized cooperation between ALMA and EVLA for high-level design sharing, while addressing overall design direction and quality concerns in the EVLA M&C system.

  1. EVLA Monitor & Control EVLA Advisory Committee Meeting September 8-9, 2003

  2. EVLA M&C and e2e Software

  3. Requirements We now have requirements produced by the NRAO user community rather than Computer Division internally generated documents. • EVLA e2e Science Software Requirements, April 15, 2003 • EVLA Data Post-Processing Software Requirements, July 3, 2003 • EVLA Array Operations Software Requirements, June 6, 2003 • EVLA Engineering Software Requirements, August 8, 2003 • EVLA Science Requirements for the Real-Time Software, to be started 9/2003 • Scientific Requirements for the EVLA Real-Time System, Sept, 2000 EVLA Advisory Committee Meeting September 8-9, 2003

  4. EVLA M&C Software

  5. Antenna MIBs • MIB – Module Interface Board • Refers to the TC11IB processor board that will be used to control antenna subsystems • 96 MHZ processor • 1.5 Mbytes on-chip RAM • 8 Mbytes Flash • SPI bus • GPIO (parallel I/O lines) • Ethernet Interface EVLA Advisory Committee Meeting September 8-9, 2003

  6. Antenna MIB Software • Quality of the MIB software is seen as crucial to the quality of the EVLA M&C software • The MIB software consists of: • Systems software • MIB framework software • Module software EVLA Advisory Committee Meeting September 8-9, 2003

  7. MIB Systems Software • RTOS kernel • Network stack • Telnet server • Automatically activates the shell • Shell • Shell provides memory display and memory modification • Shell is being extended to provide module specific commands & displays • All of the systems software is up and running on MIB hardware EVLA Advisory Committee Meeting September 8-9, 2003

  8. MIB Framework Software • Common to all MIBs • Device definition, instantiation, and initialization • A data port, broadcasts monitor data • A service port • Accepts time-tagged commands • Information services • C++, ASCII text, XML, Xpath (likely), EVLA Advisory Committee Meeting September 8-9, 2003

  9. MIB Module Software • HW module specific, chiefly written in C • Responsible for • Device Control • Collection of monitor point values • Warnings, errors, alarms • L301 (12-20 GHZ synthesizer) module software has been tested • L302 (10.8-14.8 GHZ synthesizer) module software currently under development EVLA Advisory Committee Meeting September 8-9, 2003

  10. Device Browser • Generic, discovery-based, remote client application • Obtains a list of all devices connected to a MIB • Obtains a list and description of all monitor and control points associated with a device • Can display any/all monitor point values for a device • Can modify monitor point attributes • Can be used to command devices • Peek/Poke capabilities • Multiplatform, written in Java EVLA Advisory Committee Meeting September 8-9, 2003

  11. ALMA/EVLA Cooperation • At the low levels there is little commonality between the AMLA & EVLA M&C systems. The differences are driven by differences in the hardware. • We hope sharing can occur at the higher levels of the two systems. • Ralph Marson of ALMA and I have agreed to begin monthly meetings to explore the possibilities for sharing designs and code at the higher levels of the two systems. EVLA Advisory Committee Meeting September 8-9, 2003

  12. Questions/Issues • Are we headed in the right direction ? • Overall design ? • Have we now positioned ourselves to produce a high quality overall design? EVLA Advisory Committee Meeting September 8-9, 2003
