formula node output variable

[jake83]

I have a formula node with an output variable. When i run my program the first time the output is correct. But when i run it after that, only the previous output value is displayed, the variable is not refreshing. It seems as if the value is copied into the memory and is not being updated. Is there a property for the output variable that must be changed?

You must be sure that the inputs to the formula node are changing. Perhaps you should attach the VI in question here.

The formula node should update the output each time it is run. There is no property node for the ouputs.

Ensure that (1) your inputs are actually changing as you expect - use a probe to confirm and (2) that the indicator you are looking at is wired to the output correctly.

Post an example of the problem you're seeing if you still have a problem
