is it possible to connect boolean control and indicator to the tunnel terminals of formulanode

Is it possible to connect a boolean control and indicator to the input and output tunnels of the formula node .if yes pls explain with vi

The formula node does not provide any functions for boolean algebra. I don't think that it is considered valid to argue: It does provide binary functions (like "logical or"), so why not boolean?

That being said, you can convert your boolean to a number, pass it to a node input and work with it in the node. Using a numeric output (integer) you can then convert that back to a boolean and connect it to the indicator (LED).

The formula node does not provide input/output tunnels.

Here is a vi for that, but it would be interesting to know why you want to do this.
