  1. synApps status and plans Mark Rivers October 16, 2008 based on material provided by Tim Mooney Beamline Controls & Data Acquisition Group Advanced Photon Source Argonne National Lab

  2. What is synApps? • A collection of EPICS Applications foruse atsynchrotron beamlines • Tools for translating user requirements into running code: • USER: “I need 40 motors, two scaler banks, an MCA, a monochromator, two optical tables, four current preamplifiers, 8 serial ports, four DAC channels, three slits, a mirror, run-time calcs, scans, ...” • DEVELOPER: edit startup files to configure hardware and load databases • Commissioning-level software for >80% of a new beamline • Example: Last month I was part of a team from IDT that commissioned a new beamline at the Australian Synchrotron and got first scientific data within 3 weeks of first light by using synApps. Linux system with new drivers for PCI PMAC and LCAIO analog I/O board, but same records and databases. • Support on which higher level, beamline-specific applications can be built • Run-time tools to help users meet unanticipated needs • Vehicle for collaborative development of beamline software • On the web: www.aps.anl.gov/aod/bcda/synApps

  3. Scope • Mostly infrastructure and generic capabilities, as opposed to experiment/technique-specific programs • E.g., things like motors, scalers, and scans, as opposed to things like EXAFS, small-angle scattering, and protein crystallography • Why? • Economics – Generic has the wider audience • Information & expertise – beamline developers have it; we don’t. • Control – Generic software allows us to contribute to user software without taking control over it. • Mostly IOC-resident code, as opposed to client-side programs • E.g., scan software could run on workstations, but instead runs on IOC’s • Why? • Access/coordination – IOC-resident code can be driven by anyone; clients generally cannot be driven by other clients. • Distribution/deployment – EPICS handles this for ioc-resident code.

  4. ...Scope • Some statistics: • 20 EPICS modules autosave, calc, camac, ccd, dac128V, dxp, ebrick, ip, ip330, ipUnidig, love, mca, modbus, motor, optics, quadem, sscan, std, vme, xxx • 16 record types aCalcout, sCalcout, swait, transform, camac, dxp, motor, mca, table, busy, sscan, scanParm, epid, scaler, sseq, vme • ~156 device types (~118 hard, ~38 soft) • ~205 EPICS databases • ~446 MEDM display files • ~596 source files (~318,000 lines of code) • ~160 documentation files (~38,000 lines of documentation)

  5. Content of a synApps module • Source code • EPICS records • EPICS device/driver support • EPICS databases • SNL and other code • autosave-request files • The database author figures out how to survive reboot • MEDM-display files (untested EDM translations are available) • The default user-interface tool • Documentation • Some modules contain runable examples

  6. synApps depends on software written by others • synApps also uses (“contains”? “second sources”?) some software written by others that is not in the form of a module • The idea is to avoid requiring synApps users to find, configure and test software that someone else has already found, configured, and tested.

  7. Sample user displays

  8. Who uses synApps? • Synchrotron beamlines • ~20 sectors of APS • Swiss Light Source • NSLS (>10 beamlines) • Diamond • Australian Synchrotron • Other EPICS sites • Many non-synchrotron sites use a few synApps modules, notably • motor • autosave • calc
