Folders of items are shown in gray rows as expandable folder icons  with “learned” descriptors. You can add these levels as OpcPointFolders, or simply expand to access child subfolders and/or data items. Adding folders is optional—note that any data item added (as a proxy point) automatically includes the server’s hierarchy for it (in its OpcProxyExt “Id” property).

Data Items are shown in white rows with object icons  , again with “learned” descriptors.

You can add these as Opc proxy points. If you double-click, or select and click the Add button, the Add dialog appears. This lets you select the control point type before it is added to the station. See the next section Add and Edit dialog fields.

Name

Name of the Opc proxy point, as learned from the discovery. Often left at default, unless there are multiple points using this name (equivalent to right-click Rename, can be edited anytime).

Type

The type of Opc proxy point to create (not editable after adding). A default type is pre-selected, based upon discovered OPC “Data Type” and “Mode” (RO, RW) of the data item. If mode is writable (R/W), the default is a writable point type, as either:

Otherwise if mode is RO, type selection is limited to read-only point types (NumericPoint, BooleanPoint, or StringPoint).

Id

The unique ID of the data item on the server, including its full hierarchical folder structure.

Conversion

The conversion type used between units in the proxy extension’s “Device Facets” and the units in the parent point’s Facets. Typically, this left at “Default.”

Tuning Policy Name

The assigned tuning policy for this proxy point, as configured in the OpcNetwork. See Opc Network tuning policy notes.

Opc Data Type

The Windows variant datatype of the OPC item. In most cases, the server provides this information. See Table 1 for related details.

Facets

Facets for the Opc proxy point. Equivalent to accessing facets through the point’s property sheet (and can be edited anytime). For more details, see “About point facets” in the User Guide.

Device Facets

Facets for the OPC data item, as known in the server. Will contain OPC “properties” for the point discovered by the Opc Point Manager. Typically, this value is left unchanged.
