  8. MON = MONITOR CON = CONTROL ESS = ESSENTIAL DES = DESIRED FUNCTIONS/PARAM REMOTE MONITORING AND CONTROL FUNCTIONS

  9. MON = MONITOR CON = CONTROL ESS = ESSENTIAL DES = DESIRED FUNCTIONS/PARAM REMOTE MONITORING AND CONTROL FUNCTIONS

  10. MON = MONITOR CON = CONTROL ESS = ESSENTIAL DES = DESIRED FUNCTIONS/PARAM GROUP MANAGEMENT THE POSSIBILITY TO CONFIGURE AND PERFORM FUNCTIONS ON GROUPS OF CHANNELS WITHIN A CRATE

  11. OPC SERVER • General • Compliance with OPC standards • No effect on PS output due to failure of remote control • Restart of OPC remotely • Not send set points automatically at startup – read from device • PS shall maintain its set points during PS power failure? • Genuine device and cache access • Interactive list of device functions

  12. OPC SERVER • Maintenance • To support future versions of Windows and OPC standards • To support future versions of PS firmware • Configuration • Allow appropriate management of the fieldbus • Human readable configuration file (such as XML) • Obtain actual configuration by scanning • Setting of ranges for analog values and setting of the dead band

  13. OPC SERVER • Performance • Change in Device to OPC: max 10 sec at full bus load max 1 sec for a single PS • Device cache to OPC client: max 3 sec for all parameters • Write from OPC to device: max 1 sec • Interlock to start ramp-down: max 5 ms

  14. Cooling • Forced air • Environment • Radiation < 0.01 Gy < 108 n/cm2 • Magnetic Field < 80 Gauss • Construction • Halogen free material • Safety regulations • CE certification • Reliability • MTBF > 90 000 hours

  15. Quality assurance • Production tests • Functional tests • Load tests • Documentation • User’s guide • Reference manual • Test and calibration reports

  16. Questions • Who wishes to use the spec? • For Wiener, CAEN, Arem Pro, other? • Individual or common purchasing? • When? • Adapt spec for HV supplies as well?
