Hi John,

Where have you told ADPilatus to look for the files?  Can you send a screenshot of the ADPilatus screen during a collection?

Subject: ADPilatus with PPU

 

All,

I am using ADPilatus (driver version 2.9, core version 3.12.1 ) with a PPU. In this arrangement  Camserver writes files to /ramdisk on the DCU, FURKA copies data from the DCU to the PPU /ramdisk, GRIMSEL copies the  data from /ramdisk on the PPU to network storage.

I do a scan of 361 images at 10 Hz.  I see from the directory listings the files have all appeared in network storage but ArrayCounter_RBV lags, reading ~ 211 at this point and continuing to steadily count up.

The IOC is unaware of the final destination of the files in network storage, so I don't know where  ArrayCounter_RBV  value is coming from. Do you?

Thanks,

John Dobbins
