Add-On Instruction instance tab

Use the Add-On Instruction instance tab to view the parameters and change the visibility of any Input or Output parameter that exists for the instance of the Add-On Instruction. The Add-On Instruction must have a backing tag in order to display parameters for the instance. Without a backing tag, parameters for the definition rather than the instance appear.

In the ladder diagram, right-click any parameter in the Add-On Instruction and then select
