Master and Slave Loops

[nicholas03]

I built the vi someone proposed and it did not do what I wanted to do. The graph that I originally built had all eight thermocouples being plotted as time progresses. I want this and also eight buttons that start and stop each individual data collecting. I want to be able to run as many thermocouples being collected at once as well. I am having trouble even getting one to start and stop on command. I am trying to use a case structure so that the data from each thermocouple is independently captured.

We don't know what you built, because many people proposed things. Please be more specific on what you tried.

Why don't you show us your what you made so we can offer targeted advice. 🙂

This is the vi i am using that I made but I am having difficulties. I can gather data from all 8 thermocouples and can plot them all. Now I want to be able to start and stop each one independently with buttons on the front panel. I do not know how. I also want the graph to keep going as time progresses.

Just use a case structure and either acquire data or produce a NaN instead fo each channel.

Here's a quick example using an array of eight booleans. By default all eight are enabled, but you can easily turn each one off. The time keeps going no matter what.
