Hi Folks,

I want to read data from an EPICS control system into another control system.
The setup that I have is as follows:

A Basler camera with 659x495 pixels read out by ADAravis/ADGenICam.
Attached to the driver is a NDStdArraysPlugin and an NDStatsPlugin.

The data will be accesed via an epics gateway process that runs on a gateway 
server connecting the local Epics network to the global experiment network 
using channel access

I want to read the ArrayData from the NDStdArrayPlugin and the Centroid and 
Profile information from the NDStatsPlugin at a rate of 10Hz.

If I read the unique id from both plugins and make sure the are the same, how 
big is the chance that the data does not match if I read them in two threads 
(thread 1: the  image, thread 2: the stats information)?

Would the situation improve if I can remove the gateway process?

Regards,

Jörn
