Create an alias tag

To create an alias tag, click
File > New Component > Tag
 to open the New Program Parameter or Tag dialog box. You must first set the tag's Usage to Input parameter or Output parameter because only an Input or Output parameter can be an alias parameter.
To create an alias tag
  1. In
    Name
    , enter the name of the tag.
  2. In
    Description
    , enter a description of the tag.
  3. In
    Usage
    , verify that the usage is Input Parameter or Output Parameter.
  4. Select
    Alias
     to set the tag type to alias.
  5. In
    Alias For
    , enter a reference to the local tag, structure local tag member, or bit that you want the alias tag to represent.
    Input or Output parameters can only use BOOL, SINT, INT, DINT, REAL data types. Parameter and local tag (or member) data types must match. You can only map one input and one output parameter to the same local tag or the same member of a local tag. The data type field for an alias tag is read-only, since the data type is the same as that of the base tag.
  6. If you want to make a connection to a parameter, in
    Parameter Connection
    , choose from the browser a single connection for the parameter.
    If you need to make multiple connections, select
    Open Parameter Connections
    . After you select
    Create
    , the
    Configuration Connection
    dialog will open in which you view and configure connections for the program parameter.
  7. From the
    Scope
    menu, select the scope for the tag.
  8. If you are creating an alias tag that refers to a tag whose data type is BOOL, SINT, INT, DINT, or REAL, you can choose a display style from the
    Style
    pull-down menu.
    This display style defines how the tag value will be displayed by default in the Data Monitor and Ladder Editor. It does not have to match the display style of the tag it references.
  9. For Equipment Phase only, select
    Sequencing
     if you want the parameter to be seen by the
    FactoryTalk Batch
     Server. Only Input and Output parameters can be used by a sequence.
  10. Select
    Create
    to create the tag or program parameter.
    Select the down arrow for create options. Choose:
    • Create and Close
       to close the dialog after you create the program parameter or tag (default).
    • Create and Open New
       to save the program parameter or tag you created and open another empty
      New Program Parameter or Tag
       dialog.
    • Create and Keep Open
       to save the program parameter or tag you created and keep the dialog open with the values still showing.
      If there are errors, you will be prompted.
You may also create an alias tag using the Tag Editor.
