Help! Need to save data from field point in excel sheet!!!

[Marco2907]

Hey colleagues,

I need help. I am writing on my diploma thesis.Main topic is to develop a visualization of a process of a process plant which is used for an internship in uni. My meain problem is that I need a vi where I can save my fieldpoint data only in special cycles. At the moment I use a vi which can only save every second in form of a while loop and a metronom. I am searching for a vi where I can choose the time between every saving step in excel. In addition to that I would like to have a boolean button where i can start/stop the saving within running process.

please help me urgently!!!

Hello Marco,

the answer for your problem is called “Software Control Timing”.
If a desired time has elapsed, you can write data’s to a file.
The explicit timing is the timing for your while loop, e.g. 10ms.
If a desired time has elapsed, you get a flag from a timing-function and an additional block of your code (e.g. a subVI) will executed.
The set time for the timing function is settable dynamically, while your program is running.
Find the VI in the attachment, which will provide this functionality for you.
I hope this VI will bring you further ahead….. Have nice day… Ulrich
