areaDetector fans,
I have an IOC based on
base-7.0.2
alive-R1-1-1
asyn-R4-40
autosave-R5-10
busy-R1-7-2
calc-R3-7-3
iocStats-3-1-16
sscan-R2-11-3
seq-2-2-6
it happens to be for a ADVimba camera but I don't think my issue is related to this.
When I try to use "Save Background" in NDPluginProcess nothing happens ( well I can easily verify step 2-6 below don't happen).
[from areaDetector R3-3 release notes]
Add an sseq record to load the background image from a TIFF file. This executes all the following steps:
- Saves the current NDArrayPort for the Process plugin to a temporary location
- Sets the NDArrayPort to the TIFF plugin.
- Enables ArrayCallbacks for the TIFF plugin in case they were disabled.
- Process the ReadFile record in the TIFF plugin. This reads the TIFF file and does callback to the Process plugin.
- Loads the NDArray from the callback into the background image.
- Restores the previous NDArrayPort from the temporary location.
I can verify that NDFileTIFF works and the NDPluginProcess will read an existing TIFF file successfully so it seems the sequencer automation to save the file is broken in some way.
When I press my S7F:Proc1:SaveBackground button on the MEMD screen I see that both records
S7F:Proc1:SaveBackground
and
S7F:Proc1:SaveBackground_RBV
process,
S7F:Proc1:SaveBackground transitions to Yes and stays there.
S7F:Proc1:SaveBackground_RBV
starts and stays at No.
I
am hoping for a suggestion regarding what to check next.
Thanks,
