NI Hypertrend

Effective use of NI Hypertrend.
 
I am using Labview 7.1 with DSC modul and have limited experience using Labview, but hope to get ideas from the forum.
 
My problem is to use NI Hypertrend effectively. I have experience some problems with NI Hypertrend. From my experience it is not working properly if the NY hypertrend code is placed within a while loop. I have avoided this problem with creating the Hypertrend in a separate VI which is loaded from the Main program when the operator wants to see historical og real-time data. BUT the loading of the Hypertrend is VERY slow. It takes about 30 sec to 1 minute before the hypertrend can be used to check historical data stored using the DSC moduls tag-engine in the Citadel database.
 
How can I improve this, and make the code more efficient?
 
Like the code is written today the operator of the program needs to close the separate VI with the Hypetrend, add/ remove tags to plot in the Main.vi and load the separate VI with Hypertrend once again to have a updated NI Hypertrend plotting the desired values.
 
I really appreciate some help
Best regards,
Ingvald Bardsen

Hello Ingvald!

Is your problem still an issue or has it been resolved?

Hey Ashwani,

I had to replace the laptop that I used with the control system with a newer one due to "computer crash". Now it is defintely better! But I have not changed any code. Can you suggest any alternatives to control what Hypertrend should plot (real time data and historical data) during run?
