RE: Graph displays and callbacks in QuadEM

[Mark Rivers via Tech-talk <tech-talk at aps.anl.gov>]

On quadEM screen you have AcquireMode=Single.  That will only collect one averaging cycle.  What happens if you change that to Continuous?

 

On that same screen # To average is 0.  I would expect that to be 0.5/2.4e-4 = 2000.

I have attached the screenshots.  As a warning, the IOC code is bespoke, so I may have missed something there.

Hi Iain,

 

• The numbers for e.g. “Current”, “Current (Sigma)”, and X Sum only update when I click the “Read” button next to the “Read data” label.  Is this the intended behavior?  I suspect it is, based on a comment in drvQuadEM, but I would like to verify this.

 

No, that is not how it should work.  Those numbers should update at the AveragingTime. In the attached screenshot AveragingTime is 0.5 seconds, and that is the rate at which those non-Fast values are updating.

 

Please send a screenshot of the main quadEM screen.

 

Please send a screenshot of time series plugin control if those value are not updating.

 

Mark

I am working on debugging a QuadEM, albeit one using an internal IOC.  I also want to make sure that I know how the IOC and OP are intended to function.

 

When using the standard quadEM.opi from the quadEM repo, the “(Fast)” numbers update according to the “Fast Averaging Time” parameter.  The numbers for e.g. “Current”, “Current (Sigma)”, and X Sum only update when I click the “Read” button next to the “Read data” label.  Is this the intended behavior?  I suspect it is, based on a comment in drvQuadEM, but I would like to verify this.

 

Finally, I do not see updating graphs when I look at the plots under “Time series”.  I am wondering if there is a callback I need to enable that I am overlooking.  I sometimes seem to get a single point on the graph, but nothing otherwise.

 

Thank you,

 

Iain.
