Troubleshooting common issues with DAQ

Issue

Solution/Workaround

DAQ not saving scalar data (BSA and non BSA) and getting F2_EventClass error

This is caused by a bad PV in one of the lists

DAQs returning no matches and UniqueId_RBV PV not updating + fiducial rate stuck and/or red

Reboot the server

DAQ (1D or 2D) fails and shows the following error:

Error using repelem
Replication factors must be nonnegative integer-valued scalars or vectors.

This happens when a camera trigger is not set up correctly

A workaround is to find a camera that is on the same trigger and add it to your DAQ

Ask Sharon for help if this isn't clear

Bugs and Robustness

Issue	Person	Priority	Status	Notes
DAQ should save an HDF5 file at the end of each step per camera	Sharon	High	WIP	Made most of the changes but still debugging When running a 1-D DAQ, it seems to always skip step 2
Load/clear config buttons don't work	Sharon	Low	DONE
Warning: Unable to save App Designer app object. Save not supported for matlab.apps.AppBase objects. Warning: org.epics.ca.Context@42373389 is not serializable Warning: org.epics.ca.impl.ChannelImpl@3a027fd6 is not serializable	Sharon	Low	DONE	Seems to be harmless I just suppressed the warnings
DAQ crashes and takes down the whole SIOC when total number of shots exceeds 2200 (no streaming, try with streaming on)				Reproduced this with PM03 Has to be more than 5 cameras
Background not being saved	Sharon	High	DONE
Implement HDF5 file saving for images	Sharon	High	DONE

Check what happens if new DAQ is started before old one is finished (failed abort)		High
Fix binning and ROI for CMOS cameras		Medium

Feature requests

Issue	Person	Priority	Status
Add no-camera DAQ	Zack	Medium
Add SCP Buff Acq	Zack	Medium
Support 5-10 cameras (E320 request)
(Maybe) a feature where if a camera goes down, the rest of the DAQ continues without it
Follow up to the request above: Print a "match matrix" at the end that shows matches between cameras instead of just total matches across all cameras (useful if one camera goes down but the rest of the cameras have good matches)
Add check/remove bad PVs and notify user in an obvious way	Sharon
Add nonBSA arrays so we can get UV spectrometer (Claudio request)	Sharon	High	DONE
DAQ Monitor GUI	Sharon	High	DONE
Find a way to globally trigger a modifier bit (e.g. "DUMP_2_9").	David
Scan function that pauses until you click 'ok'
Generate "camera config" file including trigger info and add a save/restore button. Monitor if this finished ok or not.	Sharon
Load/Save Config files. Default config files.	Claire
Robustness issues. . .	Spencer	High	In progress
DAN features	Sharon
Documentation/commenting	Spencer	High	In progress
Fix "Use_PV" functionality.	Sharon	Medium	DONE
