EPICS DESIGN ARCHITECTURE (I) Epics Domain

EPICS DESIGN ARCHITECTURE (II) EPICS IOC runs on Control boxes 2.Control Box provides the interface to equipment

EPICS

PLC BASED INDUSTRIAL CS 5 Standardized Roboust Long product life time Maintenance support from manufacturer Suitable performance for systems where slow control is sufficient Scalable

EPICS INTERFACES TO HARDWARE (I) 6 1.Control box running EPICS connects to the PLC 2.PLC handles all the logic 3.Preferably, all controllers are connected to the PLC using industry standard protocols (e.g. Profibus, Profinet) 1 2 3

EPICS INTERFACES TO HARDWARE (II) 7 1.Control box running EPICS also connects directly to controllers 2.However, PLC still handles all the logic 1 2

INTERFACES TO INSTRUMENTATION FIELDBUSES 8 Simple usage Easy and cheaper wiring Standardization across controllers Robust and clean interface Simplified maintenance Controllers need to support it Handling big distances Reliable and industry proven standard Higher price of controllers is compensated with less PLC equipment Incompatible with radiation

INTERFACES TO INSTRUMENTATION SERIAL PROTOCOLS (RS485/232) 9 Lose “standard“ More development effort Difficult to mantain Problems with very long cables Not so robust and reliable as profibus or profinet Many diferent logic protocols Ok under radiation

INTERFACES TO INSTRUMENTATION ANALOG/DIGITAL CONNECTIONS 10 Additional connections No clean interfaces Can require special connectors/cables Can handle difficult cases Easy to integrate into PLC I/O Shorter distances

VACUUM CONTROLS SCOPE 11

SUMMARISING 12 PLC based controls and EPICS integration Interfaces to instrumentation -> ProfiBus/ProfiNet, R485, R232, A/D Preferences about vacuum equipment with feedback information (eig. valve is open/close) The list of vacuum devices will allow us to develop a set of activities to prototype and develop also standardized controls for different devices. Software development in different stages: – Manual control of vacuum equipment – Automated control of vacuum equipment – Integrated EPICS HMIs.

Vacuum Integration Test Facility Relevant milestones – Vacuum Test Stand Control System design (Q3-2014) – Vacuum Test Stand ready for operation (Q4-2014)
