Defining Input, Output, and Memory Tags

The next thing that we’ll do is define our inputs, outputs and memory tags that
we’ll need for this project. In general, you can do I/O and data memory
definitions piecemeal, throughout the project development process – whenever
you find you need another variable or I/O point.

In this project, we will define all of the I/O points — eight input switches and
eight output LEDs — even though we’ll be using only one input switch. We will
also attach four string variables to the four lines of the display panel.

After we have defined all of the I/O, we will set up the timer that drives the
project

Lastly, we will need to define a few reusable data variables for use in our internal
calculations, but we will address those as we add each of the progress indicators.

3.2.1 Defining input bits

First, to define the input tags:

1. In the project workspace pane on the left, expand the list to show Logic

Memory > Inputs and then double-click %IX (Bits). This opens the input
tag editor window.
