Temperature control using case structure

[samolony]

I am in the process of creating a program which will aquire a signal (temperature) from a thermocouple, determine whether this is above a required maximum temperature (if this is true then i would like to initiate a case which switches off a heater output), or if the temperature is below a required minimum temperature (if this is true then i would like to initiate another case which will switch the heater on. I have attached the .vi which contains the basis of what I am trying to do but would greatly appreciate some advice as I am relatively new to this. Ps. I have researched A LOT and cannot find a method for this.

Hi ,

hope this VI would help for you.

Hi,

some small changes to the VI:

Hi, 

thanks a lot for a pointer in the right direction! exactly what i was looking for.

However, what is the icon that the max/min temps are connected into?

One last question, instead of strings to indicate whether the heater is on or off, is it possible to replace these with the physical output itself, or a function which will trigger this?

Thanks again

Hi Bloke,

that function is InRangeAndCoerce, to be found on the comparison palette.

Yes, you can include your DAQ outputs here. I guess you want to use some digital outputs using boolean values…
