Tips for using instances of Add-On Instructions
Programming tips for using Add-On Instruction instances include:
Item | Description |
|---|---|
Ladder rungs | Specify if the instruction will execute on a false rung condition if executing the instruction improves scan time. |
Data types | The tag that provides the context for executing the code uses a data type defined with the Add-On Instruction instance. Define a tag of this Add-On Instruction-defined type on the call to the instruction. |
Indexed tag | Use an indirect array indexed tag for the Add-On Instruction instance. You cannot monitor the Add-On Instruction by using the indexed tag as a data context. |
