Status of Vacuum Control System

MACS week June 2011

PP-110624-a-JWA-VacControlStatus.ppt Joachim Wallner1

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


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


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


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


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


Supervisory Control System

Sector Valve Control System

Supervisory Interface

Digital Inputs

Digital Outputs

Sector Valves

Outputs Opened/Closed

Inputs Open/Close

Beam Interlock System

Gauge Controllers

Sputter Ion Pump Controllers

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


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


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
