I tried setting those environment values before CS-Studio is started, but actually it seems to make no difference.

Looking more carefully at what "Probe" within CS-Studio shows, I notice:
  • It correctly shows 'simple' PVs from my IOC
  • If I specify an erroneous PV name, it shows "UNDEFINED - Disconnected"
  • When I correctly specify my array name, it shows "INVALID - No value"
What might cause the "INVALID" status, when the ImageJ plugin and caget can both read the data?

Those settings need to be in effect for any client running on the same machine as the IOC if the machine has 2 NICs.

Thanks Steven,

max_array_bytes should be OK.  The PV settings look OK.

Probe can't see the array - so that's quite diagnostic.
caget can report the values in the array, but also reports "Identical process variable names on multiple servers" - I'd forgotten about this.  When I start the IOC I do:

set EPICS_CA_AUTO_ADDR_LIST=NO
set EPICS_CA_ADDR_LIST=192.168.1.255

... and if I run caget with these settings, I no longer see the warning.

CSS is running on the same (Windows) machine as the IOC.  Do I need to configure it in a similar way, perhaps?

Regards,

Phil

CSS-BOY is displaying my camera control screens correctly, and my camera reacts accordingly.  It's delivering images, because I can see them in the ImageJ display or through caget; I just can't see them on the Intensity Graph widget.  Not with my own screen and not with Tomas', either.  Tomas’ screen does show a couple of the camera properties that are compatible with my camera - but the Intensity Graph widgets just show 'No data'.
 
Possible problems include incorrectly specifying the PV for the array data in the IntensityGraph configuration, or too small of max_array_bytes for the array in the CS-Studio preferences.
 
Try looking at your *:ArrayData PV using another CSS tool such as Probe (which will show you the connection status, time stamp and the first few elements of the array). Also try a right-click on the widget to select “Show PV Info” to confirm the ArrayData PV is the same as ImageJ is using.
