Read extended properties from online controllers onto HMI displays

With
RSLinx Enterprise
 version 5.90.00 or later (renamed
FactoryTalk Linx
 with version 6.00.00), you can access
Logix 5000
 extended tag properties from
Logix 5000
 controllers with firmware revision 21 or later. With this capability,
FactoryTalk Linx
 reads the extended properties that are defined in
Studio 5000 Logix Designer
 version 21.00.00 and later, and distributes them to
FactoryTalk View
 SE and ME clients. The values of the extended properties are available for use by
FactoryTalk View
 HMI displays.
To read extended properties from online controllers onto HMI displays
  1. In
    Studio 5000 Logix Designer
     version 21.00.00 or later, add extended properties to a tag (or a user-defined data type) of the target
    ControlLogix
     controller.
    For the detailed steps about adding extended properties to a tag (or a user-defined data type), refer to
    Logix 5000
     Controllers I/O and Tag Data programming manual
    .
  2. In
    FactoryTalk Administration Console
     version 2.90.00 or later (or
    FactoryTalk View Studio
     version 9.00.00 or later), open your application, and navigate to (or create an)
    FactoryTalk Linx
     server.
  3. In the
    Communication Setup
    editor, define a shortcut with the
    Processor
     shortcut type, and connect it to the target
    ControlLogix
     controller.
  4. In your application, use the format
    TagName.@ExtendedProperty
     to read the values, where
    TagName
     is the controller tag and
    ExtendedProperty
     is the extended tag property. For example,
    [Shortcut]SodaCIPTanks.Water.Value.@Min
    .
    The following extended tag property items are available for use:
    • .@Description
      : A text string from 0 to 512 characters that contains the descriptive texts as defined in
      Studio 5000 Logix Designer
      .
    • .@EngineeringUnit
      : A text string from 0 to 80 characters that represents the units of measurement associated with a tag or tag structure or array member.
    • .@Min
      : The minimum (low) value of a tag or tag structure or array member. This property is used with the
      .@Max
       property to create a high and low limit for a DINT, INT, LINT, SINT, and REAL tag. This value takes on the same type as the tag which it is associated with.
    • .@Max
      : The maximum (high) value of a tag or tag structure or array member. This property is used with the
      .@Min
       property to create a high and low limit for a DINT, INT, LINT, SINT, and REAL tag. This value takes on the same type as the tag which it is associated with.
    • .@State0
      : The State 0 identifier associated with the tag or tag structure or array member. It is used with
      .@State1
       property to describe two states of a BOOL tag. The identifier is limited to 80 characters.
    • .@State1
      : The State 1 identifier associated with the tag or tag structure or array member. It is used with
      .@State0
       property to describe two states of a BOOL tag. The identifier is limited to 80 characters.
    For detailed information about using the controller tag extended properties, refer to
    FactoryTalk View
     SE/ME User Guide
    .
  5. (Optional) In
    FactoryTalk Live Data Test Client
    , test and verify the data communication of the extended tag properties.
