Use Application Server object attributes with InTouch tags

You can use InTouch tags to interact with Application Server object attributes to transfer data between an InTouch application and an Application Server data repository.

The InTouch HMI communications protocol support includes Message Exchange. When WindowViewer runs an InTouch application, Message Exchange regards WindowViewer as an anonymous engine.

This anonymity means the InTouch application has no attributes that can be accessed by other Message Exchange clients. WindowViewer is not configured, managed, or viewed as an AutomationObject within an Application Server Galaxy. The InTouch HMI only uses Message Exchange to subscribe to those active items available from Application Server.

You can use the InTouch Tag Browser to select a Galaxy as a tag source for remote tags and browse through the namespace of the Galaxy. An Application Server object attribute or property of an attribute can be used in a remote reference or used as an item for an InTouch I/O tag.

For more information about using Application Server objects as a remote tag source, see Configure the InTouch HMI to use a Galaxy as a remote tag source.

A pre-configured Access Name called Galaxy is available in WindowMaker for Message Exchange access. The Galaxy Access Name is only relevant for the InTouch HMI in the ArchestrA environment. There are no user configurable properties for the Galaxy Access Name.
