Experimental Physics and
Industrial Control System

Hi all,

 

like announced in this tech-talk:

https://epics.anl.gov/tech-talk/2021/msg02173.php

I’m now trying to setup a FDS camera from Photonic Science with the ADPSL module. After adding some slightly changes to the Keywords that are send to the PSViewer-server or received from it, I can communicate with the camera without any IOC-crashes. I forked the ADPSL-module here:

https://github.com/MichaS-git/ADPSL

 

However, from time to time I receive some deprecated images (some lines show ~50k counts, although it is a darkfield image and the rest image has ~200 counts) and the IOC shows this error code:

 

2023/03/02 16:51:43.266 PSL:getImage: error reading image, status=4, dataLen=12117504, nCopied=12117503, maxRead=1, nRead=1453

 

In the PSViewer (the vendor software that runs parallel) the image appears fine. It seems to appear random but I have the feeling that it happens more often when I increase the exposure time to higher than ~2s. Can anyone say what that error with status=4 actually means?

 

Here is my complete IOC-start with the errors:
