BOSTEP replacement status

      Discussion 20m
      Speakers: Dr David Belohrad (CERN), Enrico Bravin (CERN), Georges Trad (CERN), Jean Tassan-Viol (CERN), Jonathan Emery (CERN), Michel Duraffourg (CERN), Stephane Burger (CERN)

      1— all MIDI stepping motors are moved to the VME controller apart from the SPS linear scanners and PSB old scanners (filter wheels)

      2— all PLC stepping motors are moved to the VME controller apart from 

      —the L4 test stand emittance meter. Likely to stay alive many years, we need to investigate if present HW is compatible with VME controller

      —the ISOLDE needle scanner , supposed to disappear soon

      3— to standardise the BTV controls, we propose to port the  BA7 BTV (HIRADMAT) motor SW from S.B. to E.B. FESA server (no HW change, please confirm)

       

       

      I’ve just wrote BI-SW to check that we agree on the 3 points.

       

      CLEAR support for PLC has ended, not clear what kind of support (PLC FW or FESA SW), all motors being ported to VME + EB FESA.

      After the meeting, mail to BI-SW:

      1— do we agree on that we’ll keep the MIDI controllers (and FESA BOSTEP) for the PSB OP scanners and SPS Linear Scanners, at least for next year ? (decision driven for minimising SW work on PSB scanners that are supposed to disappear after 1 year)
      2— apart from the slit-grid emittance meter (on cfv-152-bln4inst2, by the way, is this already FESA3 ? ) we don’t have any another PLC driving stepping motors left, right? (Michel just said there is  the ISOLDE needle scanner but foreseen to go away soon)



      Also, for  SPS BA7 HIRADMAT BTV:
      — do you have anything against porting the stepping motors control to Enrico’s FESA class  as for other BTV devices?

      Answer:

      As agreed a year ago, I was waiting for your decision to stop maintaining BOSTEP. However, there is a FESA3 version and it is working and already used in different VME.

      1- Sure
      2- The emitance is only using PLC motor via the class SteppingMotorLN4 (fesa3)
      3- As agreed with Enrico and Stephane, nothing is preventing from using Enrico's server.
