How to view an appending table from a sub_vi?

Question

I have an array of results that appends to a table every minute. This loops round 17 times then stops. On the subvi front panel, i can view these results being appended into the table row by row every minute. My problem is when i go up a level and place an indicator/table on the subvi`s table o/p, the table does not append every minute any more. It only completes the table when the sub_vi executes.
Does anyone know of a way round this. I have attached an example of my code inside the sub_vi.
Thanks
Grant

Answer 1

I could not open your VI because I only have 7.0. Just to let you know globals are ok in moderation and in some instances, I have been programming in labview for a couple of years and only had to use them once or twice. there are a couple of different ways to accomplish want you want to do. the easiest way to do this without using globals and taking up to much memory is to pass references to the subvi. What you will want to do is in the main vi right click on the table and select create reference. then in you subvi create a control reference on the front panel and reference it to a table control, then on the block diagram create a property node and set it to value, then take the same data you are writing to the table in your subvi and pass it to your property node you just created. Here is an example written in 7.0
