1 NLC CONTROL SYSTEM REQUIREMENTS DOCUMENT INTRODUCTION Description of NLC Collider Description of Control Building Description of Control Room Development & Implementation Strategies Lifetime Assumptions Adaptation, Evolution & Extension Criteria Connections to other site systems Off-site data and bin backup storage OPERATOR FUNCTIONALITY Infrastructure Networks (Structure/Bus Types/Bandwidth) Device Boot/Reboot Capability Device Firmware Download Field Bus choices Data Concentration scheme Messaging system (text & codes) Error log (exe alarm/page person/run code) Event Logging (client time stamp/tag driven?/msg distributio Buffered Acquisition Mass Streaming Data Collection WEB as a key technology Security Crate Status/poll SCADA Level Capability Contention Management Digital Status Acquisition Analog Data Acquisition Parameter Scanners (beam scan/wire scan/laser scanner) Magnet Mover Control Magnet Power Supply Control Synchronized Device Control (magnets/movers/klystrons) Save and Restore IOC Configuration Control & Restore

2 Virtual Area Designation (DGRP) Subsystem Device Control Low Level RF Control Timing System Control & Monitoring Beam Position Monitoring (linac/rings/interaction area) Machine Protection Systems Dedicated Controllers Master Pattern Generator PC based Smart Devices (sync light/interferometers/etc) GPIB Instrumentation (maybe Ethernet) Unusual devices? Feedback Systems Non-linear Feedback systems Beam-based Feedback Parameter Control (PID/Fast Feedback/Slow Feedback) File driven position & angle feedback control Data Links Detector data passing IP Beam Quality data and optimization displays Remote data analysis or event reconstruction MIDDLEWARE Definition (as applies to NLC) Application Development Services Methodologies Languages Platforms Performance Requirements Real-time capabilities Database Tools Lifecycle management

3 Persistence Directory & naming Events Time and timing Transaction processing Security Device Abstraction Contention control & prioritization Distributed objects management Device name & location database Standard devices & drivers Server Facilities & Connectivity Database Servers (RT database/bpm database) WEB servers and archives Analytical Engine Platforms Domain Name Serving Time Serving (NTP) Accelerator Parameter archives Proxies Secure Gateways Network access Mass Archive Storage Master Tool/Compiler Server

4 Application Level Capability Infrastructure Correlation Facility Plotting and Graphics Facility User Interface Scripts & Script Driven Applications Macro Facility Mathematical Analysis Tools (MATLAB) Alarm Handler (Reporting/Priority/Analysis) History & Archiving Facility Linac/Ring Modeling Linac Energy Management Optical Modeling Optics Tool Packages (MAD/DIMAD/LIAR) Ring BPM systems Linac BPM systems Beam Management Beam Based Alignment Linac Autosteering Ring Orbit Control Beam Auto Ramp-up Dispersion Correction Emittance Measurement Other Subsystems Detector Interface Beam Performance Tuning/Optimization PROTECTION SYSTEMS Personnel Protection (Stand alone system) Machine Protection (MPG Sequencing) Beam Containment Radiation level reporting & archiving Device radiation dosage & reliability

5 SYSTEM & SOFTWARE RELIABILITY Control System Reliability System Integration & Testing Hardware Reliability Analysis by conventional means Software Reliability Analysis by unknown means Fault tolerance Element redundancy Error Recovery (check sums/hamming codes/crc) Fault Recovery (failover/??) Control System Dynamic Reliability Network Performance & Slowdown Beam Position Monitor access from MPS Explicit Bypass and Bypass Management DIAGNOSTIC FACILITIES Network Infrastructure Network Performance Monitoring Network Design Capability Control System Based Local Diagnostics Self-test features in modules CAMCOM type stuff High level diagnostic code Communications test & verification software Control System Remote Diagnostics Export of Control Console Capability Security of Remote Connections Field Test Equipment Laptops & Field Testers Distributed Control System Terminals Network connections & wireless links Device Diagnostic Boxes (power supplies) Remote Vendor Test & Certification Systems

6 Stand alone systems on vendor plan floor Should be an element of Control System COMMISSIONING & INTEGRATION Commissioning starts without Control Room Need a thought out plan Network core has to be mobile Interim Control Room is mobile Partial networks between sectors Local diagnostic tools must be available early Some wireless schemes may not be available Debug from Engineering offices Integration Tie-in to Enterprise Database & conventions Interfaces to dedicated subsystems (LLRF) Interfaces to off-site facilities and staff DISTRIBUTED SOFTWARE DEVELOPMENT Software Development Environment Tools and Infrastructure Distributed Version Control Tool Distributed Requirements Tool Automated System Build Tools Centralized Resources Master Source Store(software/firmware/hw config RO Master Tool Server (compilers/cross tools/etc) Software Test Facility Representative Hardware with I/O simulation System Simulators Test & Measurement Instruments In-circuit Emulators Bus & Network Analyzers
