An OPC UA Tag object is an object used to read or write values from a device. An OPC UA Tag reading is performed automatically by an OPC UA Server, with a scan time defined on the OPC UA Subscription in which it is inserted. To use this resource, follow these procedures:

1.Right-click an OPC UA Subscription object and select the Insert - OPC UA Tag option.

Inserting an OPC UA Tag

2.A window is opened asking how many OPC UA Tags must be created on the OPC UA Subscription, and their names. This name is auto-incremented and, if this option is left blank, these OPC UA Tags are created with a default name.

Adding UaTag window

Some properties of an OPC UA Tag can be configured using the Properties List, without creating scripts for this. If users want to configure any property, locate it on the Properties List and perform the settings. The description of the properties of this object can be found on the Elipse E3 Reference and Scripts Manual.
