[Hps-controls] HPS controls meeting, Wednesday April 2, 2014

[Hovanes Egiyan]

Hi,

I posted the notes from the last HPS controls meeting at

https://confluence.slac.stanford.edu/display/hpsg/2014.04.02+Biweekly

and also pasted them to this message.

Hovanes.


    Minutes

At JLab: Ani, F.-X., Stepan, Hovanes

At SLAC: Takashi, Pelle

In Glasgow: Bryan


            SVT Motors

  * Takashi showed the slides that he showed at the HPS beamline meeting
    <https://confluence.slac.stanford.edu/download/attachments/165090867/2014-03-31StepperMotor.pptx?version=1&modificationDate=1396986671816&api=v2>
    which define what he would like to have for SVT motion control.
  * The XPS motor driver is already at SLAC
  * The cable will be ready soon, Hovanes will send at least one to SLAC
    for tests.


            SVT voltages

  * Hovanes updated on the status of the EPICS IOC for SVT voltages.
    Current the IOC has
      o Bias voltages
      o FE low voltages
      o Flange low voltages
  * Still missing the hybrid LVs. They will not be connected to any MPOD
    crates, but will be dummy records in the future to be replaced by
    the channels from DAQ CA server.
  * Ani showed the status of the alarm handler. She has  a script which
    reads the SQLite file and based on the entries in the file generates
    the alarm tree. The groups and channels have guidance buttons and
    associated action buttons.
  * Bryan already sent Ani some MEDM files that she will attached to the
    associated action buttons on the alarm screens.


    Action Items

  * Hovanes will send the motor cable to Takashi once it is ready. He
    will also sent the description of the mating connector pinout.
  * Hovanes will implement fake records for the hybrid low voltages on
    the SVT voltage IOC.
  * Ani will modify the alarm screens to launch the MEDM screens for
    individual voltage channels.
  * F.-X. will send a drawing with the location of the motors to
    Krister. (from previous meetings)
  * Pelle will find out when the SVT full test at SLAC will take place
    and let Bryan know. (from previous meetings)
