1 Vacuum Controls Status MACS week December 2010 PP-101207-a-JWA-VacControlStatus.ppt Joachim Wallner 1

2 Progress and time schedule Agreement with WP Controls about system to be used as interface between PVSS and vacuum equipment Attended to PVSS (WinCC OA) course at CERN Planned to start programming of control system Feb 2011 Further training on PVSS foreseen to be able to act as first level support PP-101207-a-JWA-VacControlStatus.ppt Joachim Wallner 2

3 Design of Vac Control System Two main parts: PVSS in combination with OPC Server for data acquisition and general controling Sector valve controller cards for interlock handling on hardware basis Each sector has at least 3 pressure sensors (gauges and ion pumps) >1 pressure sensor gives a pressure over a certain threshold  Interlock Controllers of pumps and gauges can handle 2 or more devices  never more than one device of a sector handled by one controller PP-101207-a-JWA-VacControlStatus.ppt Joachim Wallner 3

4 Design of Vac Control System Thresholds for interlocks are set in the controllers Controller is directly connected with the valve controller cards of the sector valves belonging to the sector Communication between valve controller cards and PVSS over 3 digital I/Os: Input: Open/Close Output: Valve open Output: Valve closed PP-101207-a-JWA-VacControlStatus.ppt Joachim Wallner 4

5 Design of Vac Control System PP-101207-a-JWA-VacControlStatus.ppt Joachim Wallner 5 Racks with controllers for gauges and pumps PVSS and OPC Server Rack with sector valve controllers Digital I/Os RS232 RS422 RS485 analogue Global Interlock System “Pressure threshold exceeded”

6 Interlocks PP-101207-a-JWA-VacControlStatus.ppt Joachim Wallner 6 Racks with controllers for gauges and pumps PVSS and OPC Server Rack with sector valve controllers Digital I/Os RS232 RS422 RS485 analogue Global Interlock System P t Close! Interlock! Nothing happens on the interlocks… Message to operator/vac responsible “Pressure threshold exceeded”
