“Recent” developments in EPICS-based beamline software

PPC compatible

Include files

Macro substitution

Specify restore files

Select directories for save files, request files

Dated boot backup

Reload request files

Manual save/restore works

Almost backward compatible

Request-file excerpt:

# comment

xxx:m1.DESC # comment

file myfile.req P=xxx:,M=m2

...

Include-file excerpt:

$(P)$(M).VAL

$(P)$(M).EGU

file nested.req P=$(P),Q=abc

Autosave/restore(www.aps.anl.gov/xfd/SoftDist/swBCDA/autoSaveRestore_3.13.5.tar.gz)


saveData v1.13

  • PPC compatible (EPICS >3.13.5)

  • Misc. bug fixes (stack size, trigger-PV field name, save-every-point fixed, string term.)

  • PC/Mac friendly file names, e.g.

    xxx_scan2_nnnn.mda


transformRecord v5.5

  • Test for old value failed (calc would never run) if value was NaN.

  • New field IVLA: can disable calc & output while record is in alarm

  • Backward compatible with everything in synApps

  • Scheduled for synApps 4.5


scalerRecord v3.12

  • Hold time before autocount overwrites scaler values is adjustable in st.cmd and in vxWorks console (default is 10 sec.)

    scaler_wait_time=10

  • Guaranteed to post VAL after count has finished and all scaler counts have been posted. (So clients know when they’ve received all the monitors they’re going to get.)


Substring:

Replace:

Build:

Parse:

Select field:

Concatenate:

‘abcdef’[1,3] => ‘bcd’

‘abcdef’[‘a’,’f’] => ‘bcde’

‘abcdef’{‘ab’,’XY’} => ‘XYcdef’

printf(‘abc%.2f’,1.2) => ‘abc1.20’

dbl(‘abc1.20’) => 1.2

@@(0) => 0th string arg (AA)

‘abc’+’def’ => ‘abcdef’

String calculationssee www.aps.anl.gov/xfd/bcda/medm_help/yysCalcoutRecord.adl.html


Serial O/I Block

  • Combination of string calc to construct output message, serial record to send and/or receive, and string calc to parse reply

  • Write serial-device support at run time

  • Similar GPIB support


Optical table

  • Newport (diffractometer base) geometry

  • PNC geometry


Monochromators

  • Dispersive double crystal (nested, in-line)

  • Spherical grating


Miscellaneous

  • Sample Wheel (scannable, sample averaging)

  • 4-step measurement (scannable, for dichroism)

  • Run-time table interpolation (``, feedback ctrl)

  • XIA filter/shutter


Scans

  • 4 positioners, 4 detector triggers, 70 signals

  • saveData client writes data to NFS-mounted disk

  • Can acquire 1D arrays (e.g., save MCA spectra)

  • Start/end, table, on-the-fly

  • Dedicated scan and parameter sets for 1-D automated alignment


scanSee (realtime display for 1D, 2D, 3D scans)

scanBrowser (offline display of MDA files)

NX Scan Browser (offline display of NeXus files)

IDL classes, routines for image data (plot, fit, ROI, overlay, etc.) www.aps.anl.gov/~cha/Doc.html

PVMail (send email when PV violates limits)

Channel Archiver

Clients, data analysis


plot.py - 1D real-time scan-plot demonstration

readMDA.py - read MDA files into a structure

from readMDA import *

scan = readMDA(“xxx_scan2_0001”)

detView.py - display images from MDA file

from detView import *

detView(scan[2].d[1:7])

Python
