Scan System Update Kay Kasemir, May 2015
Scan Server Sample Sample Environment Environment Equipment Sample Environment Equipments Equipments GUI: CSS REST Scan Server Script EPICS IOCs Channel Access 2 Managed by UT-Battelle for the U.S. Department of Energy
What it is and isnt* Is Automation via Channel Access Scan = Batch of commands Queue multiple scans Basic value logging Submit, monitor, pause, resume, abort Isn t Synchronization of actions beyond Channel Access Data Acquisition (log every event, catalog, keep forever) 3 Managed by UT-Battelle for the U.S. Department of Energy * .. depends on your definition of is
Set, Loop Commands Set some_pv = 3.14 Loop some_pv = 1..10, step 0.5 Optionally Await completion (put-callback) Check read-back to match written value (same or other pv) .. With numeric tolerance Timeout 4 Managed by UT-Battelle for the U.S. Department of Energy
Direction of (Nested) Loops Loop( x , 0, 5, 1) 0, 1, 2, 3, 4, 5 Loop( y , 5, 0, -1) 5, 4, 3, 2, 1, 0 Loop( x , 0, 5, 1, Loop( y , 0, 5, -1)) Alternate direction on mismatch 5 Managed by UT-Battelle for the U.S. Department of Energy
Other Commands Wait for pv1 > 100 Wait for pv2 to increment by 200 Get-callback for initial value, then monitors Log pv1 , pv2 , pv2 Get-callback for current value, to RDB Invoke MyScript Jython-based custom commands 6 Managed by UT-Battelle for the U.S. Department of Energy
Like Sequencer? Yes: Read/write Channel Access No compilation Monitor & control progress of scan Basic data log Schedule multiple scans No arbitrary C code No if-then-else command 7 Managed by UT-Battelle for the U.S. Department of Energy
Like Scan Record? Loop y=1..10: Loop x=1..5: Set det_trigger =1 with completion, Log x.RBV , y.RBV , det_counts Monitor, pause, resume, abort. Save, edit, resubmit scans vs. save/restore scan records. Add 3rd loop without rebooting IOC to add 3rd scan record Queue multiple scans Logs to RDB w/ REST readout. No MDA/XDR/Nexus. 8 Managed by UT-Battelle for the U.S. Department of Energy
REST Interface 9 Managed by UT-Battelle for the U.S. Department of Energy

Table Scan Load/save *.csv, *.xls 16 Managed by UT-Battelle for the U.S. Department of Energy
Scripted Scan 17 Managed by UT-Battelle for the U.S. Department of Energy
Parallel Command 18 Managed by UT-Battelle for the U.S. Department of Energy
Sequence Command 19 Managed by UT-Battelle for the U.S. Department of Energy
Scan Monitor Scan Monitor 20 Managed by UT-Battelle for the U.S. Department of Energy
Scan Plot Plot variables logged by scan Get data from Running or Finished scans 21 Managed by UT-Battelle for the U.S. Department of Energy
Summary Scan System helps automate SNS since 2013 Scan Server: REST instead of JNI Python API: Pure Python instead of Jython Thanks to Qui Yongxiang, Guobao Shen, Dylan Maxwell New Parallel & Sequence commands Biggest Issue: Can t use numpy (Fortran) inside Script command (Jython) 22 Managed by UT-Battelle for the U.S. Department of Energy
