All,
I am hoping you can help me understand what is happening when I try to write cbf files from a PILATUS 6M.
ADCore 3.9 ADPilatus Driver 2.9
If I write tiff files everything seems fine.
When I write cbf files it works for slow acquisition rate, say 1 Hz.
At ~ AcquirePeriod = 0.35, ExposureTime =0.09, NumImages =20
internal trigger
PIL10:cam1:StatusMessage_RBV reports a series of messages like
"Reading Image File ....."
But after ~ 13 or 14 images I get a message
"Timeout waiting for file to be created"
All 20 images appear to be written normally to disk.
I tried changing PIL10:cam1:ImageFileTmot from 5 to 10 to 20 but this doesn't seem to have any effect other than delaying the appearance of the error message.
Note our set-up is:
DCU runs camserver, collects images from detector which it writes to local ramdisk
PPU hosts IOC which communicates with camserver
Furka copies images from DCU ramdisk to PPU rammdisk, Grimsel copies images from PPU ramdisk to final destination (a network location)
Any guidance would be appreciated.
