Chapter 3 Program Add-On Instructions
Edit and Monitor an Add-On Instruction
You can:
• see the logic as it executes.
• see tag values.
• change tag and parameter values.
You cannot:
• edit logic online.
• edit logic for just this instruction.
To edit the logic, you must edit the definition.
Update an Add-On Instruction to a Newer Revision
You can update the definition of an Add-On Instruction to a newer revision.
For example, if a project uses a certain Add-On Instruction 5 times, update the definition so that all 5
instances change when you change the definition.
1. Right-click the Add-On Instructions folder and choose Import Add-On Instruction.
2. Find the instruction and choose Import.
3. Decide how to handle the conflict with the existing revision (probably overwrite).
4. Use a cross-reference list to check each use of the instruction in your logic.
IMPORTANT
Before you change the definition of an add-on instruction, make sure the change won’t cause problems
with existing instances of that instruction. When you change the definition of an add-on instruction, the
change affects all the instances of that instruction in your project.
