An OPC Block allows reading or writing a set of values. For a writing, users must set a new value to the Value property. An OPC Block reading is performed automatically by an OPC Server, with a scan time defined on its OPC Tag Group. The Size property determines the number of OPC Block Elements on an OPC Server. To use this resource, follow these procedures:

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

Inserting an OPC Block

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

Adding OPCTagBlock window

3.A dialog box is displayed to determine the number of OPC Block Elements in this object. In this option, users can indicate a mapping for all OPC Block Elements in this OPC Block or inside a given OPC Block Elements' interval.

Configure the New Block window

4.Inform an OPC Block size and its mapping options.

5.Click OK.

6.If necessary, configure this object's properties.

Some OPC Block 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. The description of the properties of this object can be found on the Elipse E3 Reference and Scripts Manual.
