This node represents an entry in the OPCDevice table. The OPCDevice table is a placeholder table used to allow an arbitrary grouping of signals into real or virtual field devices. The OPC Data Access standard has no concept of devices, and this table is required purely to conform to the table architecture required by OpenEnterprise device drivers.

Each OPCDevice table entry will reference a parent OPCServer table entry.

1.3.6.1 Context Menu

A context menu is available from this node, which enables you to Add a Group to the selected OPC

Device, pr to Modify or Delete the selected Device object. A fourth option enables you to Get Tags from the OPC Server to which the selected Device belongs.

The Add option will display the OPC Group Dialog, the Modify option will display the OPC Device

Dialog, and the Get Tags option will display the OpenEnterprise Tag Browser with the selected OPC

Server object already selected for browsing.

1.3.7 OPC Group Node

This node represents an entry in the OPCGroup table. The OPCGroup table is used to group OPC

Items together and defines how the OPC Client RDI should collect those items from the parent OPC

Server.

Each OPCGroup table entry must be associated with a parent OPCDevice table entry.
