Slow Control Activities in FZ Jülich

H. Kleines, F. Suxdorf,, K. ZwollZentrallabor für Elektronik (ZEL), Forschungszentrum Jülich

– What is ZEL?

– Industrial Automation in Experiment Control

– Example 1: Neutron Scattering

– Example 2: Target Control

– Future Activities / Cooperation with GSI



Who are we?

• Zentrallabor für Elektronik (ZEL): Central electronics facility of FZ Jülich

• ~80 Employees• Work Areas:

– Experiment Control Systems– Data Acquisition Systems– Detector Systems– New Field: Medical Systems

• ZEL is a systems house for FZ Jülich:– System design– Software development– Hardware development– Integration



Slow Control • Extreme heterogenity

– Experiment size– Application area– Technologies pre-selected by experimentator

• Technologies– Labview, SCADA, Scripting (python), Java, C++ (Qt) – TACO, OPC, Corba– Ethernet, PROFIBUS, CANopen, AS-Interface, GPIB

• “Professional” systems: Industrial Automation Equipment in Front End– PLCs– Fieldbusses– Decentral Periphery



PLCs in Experiment Control Systems• PLCs are well established in infrastructure systems

- low prices induced by mass market- robustness

- long term availability and support from manufacturer

• Increasingly being used in experiment control systems- Powerful development tools

- Strong communication capabilities: decentral peripherie (ET200S,..), dedicated CPUs for subtasks

- Real time features

• IEC1131: Just a standardisation framework

• World market leader: Siemens

=> ZEL uses almost exclusively Siemens equipment

mid range: S7-300

• Homogenous powerful programming environment: Step7 (IL,LD,FBD,ST,...)

• High modularity, scalability, extendability

• Advanced communication capabilities => distributed systems



Example1: Neutron Scattering

• SANS Experiments at FRJII• Juelich-Munich Standard:

– Middleware: TACO (Linux)

– Application: Scripting + GUI

• Front-End: totally PLC-controlled– Ca. 25 mechanical axes

– Vaccuum system

– Interlocks (beam shutter,….)
