Get array elements

[the German guy]

I have a VI that simulates the heatcycling of an oven. So far I was able to capture the powerconsumption and the temperature, everytime the heating starts or stops (with a lot of help from members of this board....).

Now I would like to do the following:

When the block temperature gets to a certain value (constant in the vi) the vi should check if the oven was heating or not. If the oven was heating at that time, I would need (lets say) the values of consumption and temperature at counter n-1 and n+1.

If the oven was not heating at that time, I would need the values at counter n+2 and n+3.

The counters here are only examples. I've tried a lot of things already. i.e. compare temperature > if true > get index of array, etc.

Anybody out there with a good idea???

Thanks a lot.

Hello Sture,

Thanks for the help. I found my mistake late on Friday evening. The case structure has a comparison attached to it which checks, when the temperature hits a given value (in this case it was 80). Unfortunately, I've set the counter of the heat-simulation to something in between 0 and 1 (which is added every time the loop goes). The value I had chosen made my heating so, that it never exactly hits 80. So there is never a true for the case. I changed that to an element, that lets me set an upper and lower limit. Now it works. If you anyway want to take a look at it, I've attached the vi again. (May be somebody else can use some of the ideas too).

Thanks anyway,

The German Guy.
