How to create an event based timer

[roiht]

Hi,

I'm using LabView 7.1 and in my application I need a timer/clock which will do the following things depending on imputs

1. When I pass 1 as an input, the timer should not increament and stay in its previous position.
2. When I pass 2 as an input, the timer should start increamenting from the previous value

3. When I pass 3 the timer should clear itself and come back to 0.

I don't need much accuracy and just resolution of seconds will suffice.

Can anyone help me out as I'm new to the LabView

Looking forward for the help

Thanks

You should use a Case Structure (equivalent of Switch Case in C) & pass the desired values (0,1,2) to it. So, there ll be 3 seperate cases in the CS for 0,1 & 2.

Perform each logic inside each of those cases as per your need.

Also, you need to put this CS inside a while loop & use Shift Regusters (SR) to keep track of the old value.
