keeping track of array memory usage

[jak692]

Hello everyone,

I am a mech engineer who has programmed casually over the years and has recently been assigned the task of creating an HMI for a compressed air system using Labview 2010.

Two tasks I need to complete involve logging alarm history and displaying a data trend.

My question is this -

I would like to hold the alarms (an array of clusters containing a timestamp and the alarm description) and data (timestamp and respective data values) each in a holding array until they get to a certain size, and then dump them into a csv file. How can I monitor the memory being used for each array so that I know when to dump it?

Also, datalogging is not something I have any experience in. Does anyone know anyone know where I can find any references online that go over good datalogging practices? I was looking for some that are specific to Labview but didn't have much luck.

Thanks everyone in advance!

Unless the description strings vary wildly in size, start with "array size" 😄
