I'm helping a new client that has existing code that heavily uses the Current Value Table (CVT) library and the network extension CVT Client Communication (CCC) Reference Library. Does anyone use these libraries and what are peoples opinions on them? I would particularly like to know if it scales well to large numbers of CVT values. The authors of these packages seem to have moved on to DCAF, which makes me worry that there are issues in using CVT-CCC.
I have a very strange Actor Launch problem. I start an Actor to do some calculations for every attached DUT. And that has been working great, 1,2,3 Actors(DUTs) no problem.
But now I’m starting to get problem when I have around 5 or more Actors that I start of the same type.
The screenshot below shows my problem.
The queue used to get the Actor’s Enqueuer back after the Asynchronous start of the Actor, didn’t receive anything.
I debugged the code, and could see that the Queue-Reference was the same for the Enqueuer and the Dequeuer. Also no errors were found on the Enqueuer Error in.
Has anybody seen something similar?
The code only fails if there are too many started actors at the same time!
I am new to cRIO, Scan Engine, and the current value table. I am trying to create a TAG configuration file and am adding all of my data acquisition channels. Each channel is of course part of the Scan Engine. I need help understanding what to put as the address for each CIE tag. I am using the NI provided tag configuration editor. When I click "Browse" and select my project, the list of options comes up empty.
Any help would be appreciated.
