NDPluginStats show the same statistics results and ADViewer displays no image

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

Hello everyone,

I am using areaDetector(R3.3.1)/ADPilatus(R2.7), but there are quite a lot problems. I would like to ask for your generous help.

I found that the 5 NDPluginStats showed same net value, same total value, same max value.... But I am sure the 4 ROIs were set successfully and they did not a share public zone. It seemed all 5 NDPluginStats showed the statistics of the whole image. I don't know why it happened. Also I tried NDPluginROIStat, which seemed not working either.

Another question is about an error printed after exposure. It said file exists but is more than 10 seconds old, possible clock synchronization problem. During a scan, it went stuck when this error was thrown out; and I clicked the Stop button on pilatusDetector.adl to move it on. Might it because the detector was not ready for the next exposure? And could I write a script to automatically set $(P)$(R)Acquire "Done" while it occurs? Will there be any disastrous consequence if I do so?

Finally, it is a problem with ADViewers(R1.5). Actually I am trying to use NFS storing all datas collected by different devices. However, no image was shown by EPICS_AD_Viewer after exposure when I set the pilatus file path an NFS path. EPICS_AD_Viewer was able to detect the image pv and no error was printed in log. When the pilatus files were stored locally, everything worked well. How can I fix this problem?

Thanks in advance.
