Connect a pen to an InTouch tag

You can connect the pen to an InTouch tagname through the Expression or Reference box. The InTouch tagname provides values at run time that control the animation and appearance of the pen.

This can be done by:

• Configuring a reference with the intouch:tagname syntax.

• Using a custom property and configuring the custom property in the embedded Industrial graphic in InTouch to reference an InTouch tag. For more information, see the InTouch HMI and ArchestrA Integration Guide.

• Configuring an application server attribute reference to the managed InTouchViewApp object that contains the InTouch tagnames as attributes. The InTouchViewApp object uses the functionality of an InTouchProxy object.

• Configuring an application server attribute reference to an InTouchProxy object that contains the InTouch tagnames as items. This is a special case of configuring an application server attribute reference.

To be able to browse for InTouch tags, you must first:

• Create a managed InTouch application by deriving an InTouchViewApp template and configuring it in WindowMaker.

• Derive an instance of the InTouchViewApp derived template.

The InTouch tags are represented by attributes of the InTouchViewApp object instance.

You may not always be able to reference the local node if you use this method of connecting to the InTouch HMI software. As a result, you may have problems with some applications. If this is the case, use the intouch:tagname syntax.

With the intouch:tagname syntax, the pen connects to the InTouch tag on the symbol’s node. There are some restrictions on how you can use this syntax:

• Unlike in Application Server, you cannot use TRUE and FALSE as Boolean values. Use 1 and 0 instead.

• If you want to connect to an InTouch SuperTag with this syntax, use the following syntax instead:

  attribute("intouch:SuperTag\Member")
