MOD 30ML Display Guide

Application Examples

A connection is then made from input STOP in each of the Display Blocks to an Expression

block that controls the scrolling, as shown in the next figure.

In this example the Expression Block uses inputs 1 through 3, configured as Count inputs, to

detect the “stop scroll” command from the Display Blocks named TAG1, TAG2 and TAG3.

“DISPLAYS” is a count input with an initial value of 1, that increments the display index

number by 1 until it reaches 3, then resets to 1 and starts again, as long as none of the “stop

scroll” inputs is present. The result of the Expression must be connected back around to the

input DISPLAYS.
