i have a vi lets say ex1.vi. this vi has 2 inputs 1)sensor 2)message. 1 output, parsed message. this vi has a while loop which upon changes in the input, should update the output. this vi itself is in a message loop where the vi that instantiates this ex1.vi produces the message and signal and consumes the parsed message. now i want the output to be updated with changes in the input without breaking the loop in the ex1.vi. is this possible without the global variables?.
