Topic 13.5.1: Remote Tags

  • Remote Tags

    • You can create distributed InTouch applications with a tag server running on a separate node from the node running the InTouch application. The following figure shows an InTouch application that makes a remote reference to the PumpRPM tag from a tag server running on another node.

  • Key Points
    • You can reference remote tags by two methods:
      • Associate I/O tags with an Access Name that identifies a remote server as the tag source.
      • Use a remote reference directly to the tag. For example, PLC1:PumpRPM.
    • When you want to directly reference a remote tag in any other application, only AccessName:Item is required. You do not have to define the remote tag in your local Tagname Dictionary. Remote references can also access data from any I/O data source such as a DAServer or Microsoft Excel.
    • You can also make a remote reference to SuperTags. The valid syntax for a remote tag reference to a SuperTag is:

      Access_name:Parent_Instance\ChildMember\SubMember.

    • You can redirect ArchestrA object references or remote references to InTouch tags at run time with a script. You can switch object instances for a graphic symbol based on certain conditions being met or directly by an operator action.
