ST/MO Prototype plans• Phase I (October 2000 to January 2001)

– Functional model with alarms, mimics and trends• TDS data acquisition -> PVSS driver

• TDS data loading -> generic data loading mechanism

• Inter system communication with Gamma Irradiation Facility (GIF) experiment

• Phase II (February to June 2001)– Performance tests and further development

• High data rates, many concurrent users, full TDS data set

• Customized general data loader

• Library of reusable standard symbols

• User tests in TCR

Data exchange

• 245 Data point elements

• 115 CAS alarms

• 2 trending parameters

• 6 commands

• 1 mimic diagram

4th ST Workshop, Chamonix 2001 U. Epting, M.C. Morodo Testa, P. Sollander

ST/MO Prototype results– Data acquisition

• TDS driver available on Linux and NT

– User interfaces• PVSS standard alarm screen with CAS data

– Works, but some configuration issues remain– A CERN wide PVSS alarm screen looked upon by SL/CO

• PVSS mimics– Reusable objects available, drag-and-drop view creation, easy to

use, fair graphics, integrated trending tools

– Data loader• Standard ASCII manager works, can be improved with

specialized tools to obtain better data integrity

– Data distribution• Ok for small scale, to be tested more large scale

ST Strategy (1)• Needs in terms of controls are not uniform

• ST-AA, ST-MO:– Some common requirements:

• Multi-platform

• Data exchange and integration

• CERN wide support

– Various systems used today• TDS (component ware)

• LabView, FactoryLink, DataViews, Tcl/Tk

– PVSS can fit (if evaluation results are positive)

– Towards a single SCADA by LHC start-up

4th ST Workshop, Chamonix 2001 U. Epting, M.C. Morodo Testa, P. Sollander

ST Strategy (2)ST-CV, ST-EL, ST-TFM:

– Control requirements are specific to their processes– Standard industrial control architectures for the LHC in use

• Feasibility and design phases have been completed• Installations are already in operation• Implementation is integrated in large-scale industrial contracts• Long-term maintainability with C168 contract

ST-CV, ST-TFM: Wizcon®

– Project started in 1997– Israeli product (free)– PVSS/Wizcon® integration foreseen with Atlas/CMS

ST-EL: Scatex® – Project started in 1998– Specifically adapted to ENS requirements– Turn-key approach

4th ST Workshop, Chamonix 2001 U. Epting, M.C. Morodo Testa, P. Sollander

CERN Controls Division Strategy• Keep numbers of SCADA products as small as

possible– Today: WIZCON, PCvue, WinCC and PVSS, ScateX

• Converge to a single product if possible– Migration costs and effort?

• Define clear interfaces between systems– OLE for Process Control (OPC)– PS/SL - Middleware project

• Provide central support and guidelines– SCADA User Group? PVSS seminar ...

4th ST Workshop, Chamonix 2001 U. Epting, M.C. Morodo Testa, P. Sollander

World Strategy• Let’s see at the next ICALEPCS 2001 …

– 8th International Conference on Accelerator and Large Experimental Physics and Control Systems

ST Strategy (2) ST-CV: Wizcon®

– 1997: SCADA feasibility studies and evaluation for CV Controls

– Fits to CV process controls• Flexible data sharing

• Regulation: accuracy, reliability

• Widely used in industrial environments outside CERN

– Israeli product • Privileged commercial

framework

– PVSS/Wizcon® integration • Already agreed with Atlas/CMS

– Long-term maintainability• In-house expertise + C168

ST-EL: Scatex® – 1998: Initial phases of the CERN

Electrical Distribution Network control system project (ENS)

– Specifically adapted to ENS• Powerful central control system

• Local supervision and interfaces to the electrical equipment (RTUs)

• Operational in other electrical applications outside CERN

– Turn-key approach• The Contractor is responsible for all

the system’s life cycle

– Long-term maintainability• C168: Preventive maintenance
