Hi:
I have two questions in the labview program to ask.
1.
The .exe file, originated from this labview source file, is now working properly. After I installed the Labview 2010 in my laptop and opened this source file, there is a wiring problem about the thermal couple appeared. I did download the sub_VI of the thermal couple (LabJack, U6) from the company website and linked it to the source file. Therefore, I am not sure the reason of having this message of wiring problem. Based on the hint, I opened the "Context Help" and saw the window at top-right concer of the attachment.
If anyone has the idea of fixing it, please let me know.

The original function of this source file is to switch on/off the power supply under the targeted temperature. Now I try to add an interlock, switching off the power supply when the temperature is over 80C for a certain time period (say ~2 hrs). In the whole loop structure, the load temp will be read every 5s. The way I am thinking now is to design a counter and link it to the case structure (see red circle 2). I use the "Formula Node" and write the counter inside. I setup the load temp as the input variable "T". If T is over 80C, the variable y will be added 1 every 5s. If T is less than 80C, y will be reset to 0.
Please let me know whether the code in the Formula Node and the whole idea are workable. I am not sure whehter I should initialize y as 0.
