LogicPro User’s Guide Chapter 8: Ladder Diagrams

Doc.# 28002-00 Rev 3.00 Watlow Anafaze 93

Figure 8.11 Connecting an Element to a Func-

tion Block’s Output

Figure 8.12 Function Block After Connecting

Output Element

NOTE! If the Function Block’s first logical input is con-

nected directly from the left power rail without any

element in between, a constant True condition is

applied during the running of the control pro-

gram. However, for the other logical input, if there

is no connection between it and the left power rail,

a constant False condition is applied.

Inserting Parallel (Or) Branches

There are two ways you can add a Ladder element parallel to

an existing element.

To create parallel branches, there must be elements on both

sides of the element you want to parallel. Figure 8.13 on page

94 shows the Ladder diagram before the parallel branch is

added, while Figure 8.14 on page 94 shows the Ladder

diagram after the branch is added.

1. From the toolbar, select the element type you want to

add.
