An OPC Tag is an object to read or write values from a device. A Tag reading is performed automatically by an OPC Server, with a scan time defined by an OPC Group where it is inserted. To use this resource, follow these procedures:

1.Right-click an OPC Group and select the Insert - OPC Tag option.

Inserting an OPC Tag

A window is opened asking for a number of Tags to create in this Group, as well as their names. This name is auto-incremented and if this option remains blank, Tags are created with a default name.

Adding OPC Tags

Some OPC Tag properties can be configured using Properties List, without creating scripts for this. To configure any property, locate it on Properties List and perform the necessary adjustments. For more information on properties, please check the E3 Reference and Scripts Manual.
