Stephanie Allison Integration with the SLC Control April 7, 2005 All boards built - 1 production, 2 spares LCLS (Dayle Kotturi) tested board with minimal driver software - no problems found PNET receiver SW requirements done Prototyping in-progress EPICS device support design in-progress PNET Receiver Module Progress Since Oct 2004

Stephanie Allison Integration with the SLC Control April 7, 2005

Stephanie Allison Integration with the SLC Control April 7, 2005 Receive SLC messages and act on them in the same way as existing SLC micros for: BPM-Like Data Acquisition (Gated ADCs) – beam synchronous Magnet-Like Control and Readback (All Controlled Devices) PNET Timing Diagnostics Maintain its part of the VMS SLC database: Receive the entire SLC database at initialization time Receive new setpoints at any time from the Alpha Send readbacks back to the Alpha on request and periodically Send setpoint changes made by external EPICS applications to the Alpha Goal – same amount of network traffic as SLC micros SLC IOC – What It Will Do

Stephanie Allison Integration with the SLC Control April 7, 2005 MPS BITBUS Power Supply Control KISNET Communication Micro-to-Micro Communication via Alpha SLC-style Analog Signal Monitoring SLC-style Digital Input/Output SLC-style Error Logging (use CMLOG instead) SLC-style Klystron Interface SLC-style Video Interface SLC-style Timing Interface (except PNET diagnostics) Direct Hardware Access (and no support for “virtual CAMAC” commands) Debugging from VMS SLC-Style Fast Feedback Interface Keep static data in the EPICS and SLC database up-to-date SLC IOC – What It Won’t Do

Stephanie Allison Integration with the SLC Control April 7, 2005 Piece-Meal functional requirements – big picture not always clear Endian – VMS to/from any possible EPICS platform (no 64 bit) Memory – CPUs that support SLC-aware IOC need memory Restart SLC tasks without restarting the IOC Detail diagnostics needed via the IOC shell, a subset via CA Keeping the EPICS and SLC database in-sync – 2 master problem Particularly for Magnet Control May need to increase max # of “micros” in the SLC control system May need a second proxy in the SLC production control system Magnet/BPM applications slow in developing SLC-Aware IOC Issues

Stephanie Allison Integration with the SLC Control April 7, 2005 Team: LCLS Controls: Stephanie Allison, Kristi Luchini, Consultants ESD Software: Diane Farley, Debbie Rogind, Ron MacKenzie, Consultants Weekly meetings and working web pages Coding standards implemented and development environment created Basic Services: Requirements done and reviewed Designs done and reviewed Executive, Message, Database, CMLOG – Done except for RTEMS testing and cleanup, identifying some new requirements (2 full-time) Async Utilities and Periodic “Micro” Health Update – implementation in-progress (1 full-time) Changes to VMS programs done Application Services: Device Control and Readback (Magnet) – Reqts in-progress (1 part-time) PNET Timing Diagnostics – Reqts in-progress (1 part-time) Gated ADC Acquisition (BPM) – no progress Changes to VMS Programs – not yet defined Record Naming Conventions – first draft done SLC IOC Progress Since Oct 2004

Stephanie Allison Integration with the SLC Control April 7, 2005 SLC database work to define all devices on each SLC IOC, SCP panels, configuration files MPG timing pattern generation Tool to generate consistent EPICS and SLC databases Minor changes to VMS applications identified for SLC IOC magnet and BPM jobs (replace “virtual” CAMAC commands) Add LCLS modelling Other work TBD Existing VMS SLC Applications Changes/Additions
