Use InTouch with multiple galaxies

You can use an InTouch application as a client to access data in a multi-galaxy environment in the same way you would access data within a single, local galaxy.

You can use the InTouch Tag Browser to select an Application Server object as a tag source and browse the Galaxy database in a multi-galaxy environment in an almost identical fashion to the traditional browsing workflow described in the InTouch HMI Data Management Guide.

Application Server object attributes or attribute properties can be used in remote references or as items for InTouch I/O tags in a multi-galaxy environment.

The address syntax changes for use in a multi-galaxy environment. The following is an example of a Galaxy reference used within a single galaxy:

Galaxy:Pump1.PV

The following is the same reference with the same access name, but used in a multi-galaxy environment to target a remote galaxy named "Factory2", containing object Pump1 with attribute PV:

Galaxy:"Factory2:Pump1.PV"

The entire expression, enclosed in quotation marks, becomes an item name. This syntax can be used in Industrial Graphics .NET scripting, and in InTouch scripting.

Important: If you manually enter custom property overrides for an Industrial Graphic, do not enter the double quotation marks shown in the example. Browsing automatically provides the correct syntax, without the quotation marks, for custom property overrides. This syntax variation applies to custom property overrides only.

You can define a paired galaxy as a tag source, with an InTouchViewApp leveraging the galaxy pairing already configured in Application Server.

You can then use the Galaxy Browser to access the Galaxy namespaces of the paired galaxies.
