Slow Control Activities in FZ Jülich H. Kleines, F. Suxdorf,, K. Zwoll Zentrallabor 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

Simatic S7 PLC Family high end: S7-400 Ethernet, MPI, PROFIBUS mini: S7-200 mini: IM151/CPU OP + S7-300: C7SoftPLC: WinAC Decentral Pheriphery: ET200L, ET200S, PROFIBUS + AS-Interface AS-Interface 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,….)
