Example #2

An InTouch data source object allows you to group related InTouch tagnames together under the InTouch group object. Items can be added to InTouch group objects in the same way as they are added directly to the InTouch data source object. The same InTouch tagname is referenced whether the item is added directly to the InTouch data source object or to an InTouch group object.

Assume a configuration with an InTouch data source object called "MyInTouch" and a single group object called "Cleaner".

OPC Client

OPC clients can add items to either the InTouch data source object or to the group object. Fully qualified OPC item names are created by concatenating the hierarchy tiers, separated by periods. The following two examples are equivalent:

MyInTouch.TankLevel

MyInTouch.Cleaner.TankLevel

DDE/SuiteLink Client

DDE and SuiteLink clients add items to the Device Group associated with either the InTouch data source object or its group object. The topic the DDE/SuiteLink client needs to connect to Gateway Communication Driver is provided by this Device Group. The Device Group is created automatically when you create either the InTouch data source object or the group object in the hierarchy.

The item name for a DDE or SuiteLink client would be as follows:

Application: Gateway

Topic (Device Group):

MyInTouch

or

MyInTouch_Cleaner

Item: TankLevel

Excel cell reference:

=Gateway|MyInTouch!TankLevel

or

=Gateway|MyInTouch_Cleaner!TankLevel
