I was experimenting outside the box again and needed to have single touch and double touch status for HMI buttons. So - see attached project. PAC (SW 4.2.0.39) and Cmore (SW 8.21)

On the HMI, note that I have not put tagged indicators (circles) on rows 6-9.

Single-Touch a gray square, the larger circle's visibility should toggle on and off

Double-Touch a gray square, the X/O indicator should toggle X -> O -> X

I attempted to describe each rung/branch.

This project is an extension of my 'abstract' timer [think arduino millis() timing] project that I have posted here, but cannot locate.

use it as you see fit
