It would be nice if you marked my answer as the solution instead of your thank you. You can change the markd solution by clicking on 'Options'.
First, you do not have a schematic. You have either a front panel or block diagram. A schematic is for electronic symbols.
If you want to know when it changed, then a simple way is to wire a case structure to the Boolean and place a Get Date/Time function in there. If you want to know the current position, that is being displayed in the axis info indicator. If you want to display the delta, then subtract the previous position from the present position. Just wire both clusters up to the subtract function. You could also put a write to a table of the delta information/time inside the case structure. A table is just a 2D string array so you would have to convert the cluster elements to an array with Cluster to Array and then convert to strings, Another shift register with a Build Array would handle the writing to the table.
Try writing something and see how far you get.
