Timing problem with alternating on/off

[XebeXUC]

Hello all

For my project I need to alternate two LEDs, I have found a way to do this, but it isn't a very good one.

Now I have placed a wait with a large time, inside a case. So in case the statement for starting the alternation is true, my entire program will slow down.

I tried to use the 'elapsed time', but then one of the LEDs is on for a short period of time, but I want them both to be blinking at the same rate (which I can choose), but opposite of each other.

The idea is that the LEDs will be replaced with digital outputs to open and close valves.

Apart from that the program works pretty good.

You only posted a screenshot of a small portion of your VI.  We can't tell what is happening in the rest of the VI, what else is inside the loop, what is in the False case, nor what boolean value is driving that case structure.

Post an actual VI.

It's a large VI, with many other different things, for now it's just a simulation, but I'll add a smaller version of the VI.

It basically simulates that when the temperature or pressure becomes to high, both valves need to alternate between open and closed.

Hello XebeXUC,

If I understood your problem, this is my solution :

And attached, the false condition

Hope it helps

Where would I set the time one LED has to stay on? (I guess blinking speed)

In the future real (hardware) project, they should be on for about 1-2 minutes.

Also, I'm having trouble connecting the second select, for some reason I can't insert boolean.

I only have LV2011 so I can't read your VI

You should set the "blink speed" command at 60000 (ms) to set a 1min blink time.

Alright, it seems to work good, thanks a lot for your help.

I added a x1000 for convenience.
