LabVIEW Multiple Independent Timers with Non-Reentrant Sub VI's

[Jason_D]

Overview: This example shows how to measure the elapsed time in separate calls of a non-reentrant subVI. You cannot use the Elapsed Time Express VI that ships with LabVIEW to accomplish this task because resetting the VI from one call of the non-reentrant subVI resets the timing in all of the subVI calls.

---

Description: This VI shows how to properly create multiple independant timers. Notice that you cannot use the Elapsed time VI as that shares a common reset line and will reset all instances of the VI.

This example stores multiple start times in an array of indexed timers so that you can measure the elapsed time in each separate call of a non-reentrant subVI. The example includes the Multiple Elapsed Times VI that performs the elapsed timing function. The example also includes a VI that calls Multiple Elapsed Times.vi and shows how to use this VI in non-reentrant subVIs. Multiple Independent Timers.vi is the main VI.

---

Requirements: LabVIEW 2012 (or compatible). Hardware: none.

---

Steps to Implement or Execute Code: Run the VI, use controls to manage timers, follow the indicators on elapsed timers.

hello,

How to add a button pause for this?

Thanks.
