Open from multiple processes

Postby Ondrej.Janda » Thu Oct 18, 2018 3:27 am

Hi,
I was wondering if it is possible (using the VINT hubs) to open and attach channels (let’s say DI) on one physical hardware (DAQ1200_0) from different contexts/processes. Basically each process reading its own DI (different index).
I know it is not possible with the InterfaceKit 8/8/8, probably because the USB is blocked for the first process that asks for it, but I am wondering if anything changed with the VINT.

Thx,
Ondrej

I believe this is only possible if you access it over the network.

Since the VINT devices are all accessed through a the VINT hub (which unless you're using a SBC, is a USB device) you wont be able to access it from two processes.
