Vacuum Control System MACS Week Progress Report June 2011

This report details the progress made in the Vacuum Control System MACS project as of June 2011. Updates include the completion of the Vac Controls Design report, identification of vacuum controls equipment, and decision to use PLC for Sector Valve Control System, among others. The Controls Principles and Interlock Conditions are explained. Future plans involve implementing XML device definitions, achieving fully functional controls of fixed pumping groups, and conducting WinCC OA training. The schedule for 2011 outlines upcoming tasks for fixed pumping groups, Sputter Ion pumps, NEG pumps, Sector Valve Control System, and panel installations. For further inquiries, contact Joachim Wallner.

  1. Status of Vacuum Control System MACS week June 2011 Joachim Wallner

  2. Progress since the last MACS week 1/2 • Vac Controls Design report finished • Vacuum sectorization • System architecture: • Supervisory Control System • Frontend Control Hardware • Sector Valve Control System • Controls principles • Interlock conditions • Deployment scenario • VM with WinCC OA and Matrikon OPC Genie for control system development provided by WP Controls Joachim Wallner

  3. Progress since the last MACS week 2/2 • Vacuum controls equipment identified • Contract for gauges, turbopumps and controllers signed • Controls electronics for fixed pumping groups designed • Decision to use PLC for Sector Valve Control System • Serial device servers acting as interface between Supervisory Control System and Frontend Control Hardware ordered • Digital input and output modules for control of fixed pumping groups ordered • Pending: • Sputter ion pumps + controller tendering in progress, ends in July • Non-evaporable getter pumps direct purchase in July Joachim Wallner

  4. Controls principles (1/2) • Sector control • For generic control each vacuum sector is represented as a state-driven device • Direct control • A restricted group of vacuum experts is allowed to control each device directly via the WinCC OA GUI • Intended to be used only during commissioning and maintenance Joachim Wallner

  5. Controls principles (2/2) • All vacuum devices within a sector belong to this sector and are controlled by the corresponding state-driven device • The components of a fixed pumping group (primary pump, turbopump, valves) are grouped under one basic device and controlled via a CTRL script • Rules for sector valves • In general the downstream (in beam direction) valve belongs to the sector • Exception at MEBT/Sync crossing and first valve at extraction • In treatment lines the upstream valve belongs to the sector • Condition for opening of a sector valve: All gauges and ion pumps have to give a pressure below a certain threshold Joachim Wallner

  6. Sector valve control system • Based on Siemens S7-300 PLC • Switching function outputs of all gauge and ion pump controllers which are used for interlock triggering are directly connected to the inputs of the PLC • Programmer available for 2 months in 4th quarter of 2011 Joachim Wallner

  7. Interlocks • Each sector valve has at least 3 pressure sensors (gauges, ion pumps) assigned • If at least n-1 sensors give a pressure above a certain threshold the closing of the sector valve is triggered  signal to BIS • If a valve closes due to a too high pressure also all neighbouring valves get closed Joachim Wallner

  8. Ongoing activities andplans until next MACS week • XML device definitions • Fully functional controls of fixed pumping groups • Communication between WinCC OA and controls equipment (gauge controller, turbopump controller, controls electronics of primary pump and valves) via MatrikonOPC Server, serial device adapters and digital I/Os • CTRL script • GUI • WinCC OA training at ETM premises in September Joachim Wallner

  9. Schedule for 2011 • Fixed pumping group: July/September • Sputter Ion pumps and NEG pumps: October • Sector Valve Control System: November • Vacuum sector controlled as state-driven device: November • Panels: December/January Joachim Wallner
