MC read vi cant execute in parallel?

 

Hello Everybody,

 

I got a question regarding MC DAQ read vi.

I need to read data in two different CAN interfaces with the MC DAQ read vi (in polling mode), so I create two loop in parallel. In theo, two loop should be runing in parallel, the time of loop exucution wont incrase by 2. But after experiment, the result is discouraging, loop duration is indeed doubled.

The issue is this vi is protected by password, that means I cant open its diagram.

Is there anyone know how to open it (the password) and what prevents it to be runing in parallel?

To run two of these tasks in parallel, the ECU modules need to be reentrant.  A search of the manuals for the words "reentrant", "re-entrant", and "recursive" found no matches.  You might contact NI directly ...
