Using Add-On Instructions

Add-On Instructions are used in your routines like any built-in instructions. You

add calls to your instruction and then define the arguments for any parameters.

The Add-On Instruction can be used in any one of the Ladder Diagram, Function

Block, or Structured Text languages (including Structured Text within Sequential

Function Chart actions). The appearance of the instruction conforms to the

language in which it is placed.

The Add-On Instructions in the project can be accessed from any of the normal

instruction selection tools.

The instruction toolbar has an Add-On tab that lists all of the currently available

Add-On Instructions in the project.

Important: Safety Add-

On Instructions can be used only in safety routines, which are currently restricted to

ladder logic. Safety Add-On Instructions are shown in the Language Element toolbar only

when the routine is a safety routine.

Follow these instructions to access the Add (language) Element dialog box.

1. Press Alt + Insert anywhere in the editor or right-click the logic in the

Editor and select Add Element.
