Adding a New Add-On Instruction

Use standard Add-On Instructions to store commonly used logic as a set of instruction and then add it into to your project. Once defined in a project, Add-On Instructions behave similarly to the built-in instructions already in the Logix controllers.
Use safety Add-On Instructions to encapsulate commonly-used safety logic into a single instruction. In addition to the instruction signature used for high-integrity Add-On Instructions, safety Add-On Instructions feature a safety instruction signature ID for use in safety-related functions.
To add a new Add-On Instruction:
  1. In the Controller Organizer pane, expand the
    Assets
     folder, right-click the
    Add-On Instruction
     folder, and choose
    New Add-On Instruction
    .
    The New Add-On Instruction dialog box opens.
    Note that you can also access the
    New Add-On Instruction
     dialog box using the following path:
    File > New Component > Add-On Instruction
    .
  2. Type a name for the instruction.
  3. If in a safety controller project, choose the class for the instruction:
    Safety
     or
    Standard
    . For more information on safety Add-On Instructions, see About Safety Add-On Instructions.
  4. Select the programming language for the definition logic (this can only be ladder diagram for Safety Add-On Instructions).
  5. (optional) Complete the
    Extended Text
    ,
    Revision Note
