Configure the InTouch HMI to use a Galaxy as a remote tag source

You can use the InTouch Tag Browser to select an Application Server object as a tag source and browse the Galaxy database. Application Server object attributes or attribute properties can be used in remote references or as items for InTouch I/O tags.

When an InTouch application runs as a client providing the visual interface for an Application Server application, you must install Application Server Bootstrap and a WinPlatform object on the same node as the InTouch application.

To browse the Galaxy namespace from the InTouch HMI, you also need to install the Integrated Development Environment (IDE).

The InTouch HMI uses the Message Exchange functionality of the Platform to view the Galaxy namespace and provide better data communication.
