May 2001


Control System Scope

“The DIAMOND control system will be a site wide monitoring and control system for the accelerators, beamlines and conventional facilities. The control system will extend from the interface of the equipment being controlled through to the operator. It will include all hardware and software between these bounds: computer systems, networking, hardware interfaces and programmable logic controllers. “

“The control system will not include any control or data acquisition for the experimental stations. It further will not include the personnel protection system, which is a separate system that will be monitored by the control system.”


May 2001


Control Systems Includes

• Consoles

• Networking

• Equipment Interface

• Protection and Interlocking

• Timing and Event generation and distribution

• Wideband (RF) and Analogue Mux systems

Summary of Interface Requirements

• Total Devices to Control 3781

• Total Number of IOCs 176

• Devices per IOCs approx. 22

• Likely number of PVs 100,000 ????

Immediate Tasks

• Training of Staff on EPICS

• “Understand” IOC Databases !?!?!?!?

• Evaluate EPICS Device support

DIO,AIO, Serial, GPIB, Ethernet

• Evaluate existing Driver support

Produce list of supported instruments

Identify areas where development is necessary


May 2001


Serial Interfaces

• Need to support Serial Interfaces to equipment

• Advantages are

Increased functionality per connectionMinimises calibration errors from Control System ADCsWidely accepted use of RS232,422 etcIntegration of systemsFaster commissioning

• Disadvantages are

High processor loadDevelopment to support vendor protocolsAlso need hardwire analogue for fast logging and digital for

Interlocks


May 2001


Equipment Protection Policy

• The Control System will manage protection of equipment where required.

• Give consistency of behaviour.

• Three levels of protection determined by assessment of damage/cost caused by failure

High Integrity : provided in hardware

Routine Interlocking : provided by PLCs

Prudent Operational Limits : provided by IOC DBs


May 2001


Relational Database

• DIAMOND Control System MUST have a relational database

Contain as Minimum the IOC DBs, Device names, and ???

• Review other EPICS uses of RDB from June 2001

BESSY II, SLS, SNS

• Define tools and processes for producing IOC DBs and importing / exporting data to and from RDB


May 2001


Applications Interface

• Need to integrate seamlessly other sources of information at the application level

RDB, Acc model and ????

• CDev provides one solution

Low overhead

Allows retention of core Epics extensions medm etc

• Want support for Win API most likely through ActiveX

Industrial Support

• Can we buy EPICS ready systems from industry?SLS Linac from Accel

SLS RF from Thomcast

Power supplies ???

BPM diagnostics from Instrumentation Technologies

Support for beam position feed back system

EPICS support from Observatory Sciences Ltd in UK

• VME manufacturers already offer support in the form of EPICS drivers

Hytec in the UK


May 2001


A Model For Procurement

• Contract out build, install and commission of large parts of the Control System, by defined packages of work

Consoles and ServersNetworkEquipment Interface per technical area

Magnet PSU, RF, Diagnostics, Vacuum, Linac, …..

• Provide integration at the IOC level

• CLRC then has responsibility for overall integration

• Effective way to manage risk in procuring the control system

Conclusion

• EPICS is not as frightening as led to believe !!

• EPICS is a very good choice for an accelerator control system

• Lots of issues to resolve for DIAMOND control system

We need to consult the EPICS community

• Confident EPICS will enable

The Control System to be available from day one of accelerator operation

The Control System to support commissioning and operation of the accelerators not hinder
