Feet Per Meter Help

[draganjr]

Good Evening, new to this forum and new to program with Unitronics.

I will attach my program so yall can see what I am doing, trying to do.  And Thank you in advance.

I made a simple program that will allow two different prox to read and output data (numbers).  
One will be a forever timer and the other with be for presets and allow a sprayer to mark at said preset.  
Along with other bells and whistles.  My next project is to write a script that will allow Feet Per Minute (tachometer) meter to show on the display.  
Things I don't know would be sensor type to use and how to program it to show it on the display.  I think I have the wiring down.  
The two other sensors are PNP 3 wire 24 DC.  The solenoid for the sprayer is 24v 2 wire.
