When you create new bindings, often they share many common characteristics. For example, you may be binding to OPC items all residing in the same OPC server, or using the same parameters, such as the update rate.

In order to make it easier to create such similar bindings, parameters of newly created bindings are taken from parameter templates.

For OPC Data Access (OPC-DA), you can configure following templates on the DAConnectivity component:

• ItemReadParametersTemplate: OPC-DA read parameters, such as the data source (cache, device, and so on), in newly added bindings to OPC items.
• ItemSubscribeParametersTemplate: OPC-DA group parameters in newly added bindings to OPC-DA items.
• ItemWriteParametersTemplate: OPC-DA write parameters (such as whether just the value, or the whole VTQ triple should be written) in newly added bindings to OPC-DA items.

For OPC Unified Architecture (OPC-UA), you can configure following templates on the UAConnectivity component:·        

• AttributeReadParametersTemplate: OPC-UA read parameters (such as the maximum value age) in newly added bindings to OPC-UA attributes.
• AttributeSubscribeParametersTemplate: OPC-UA subscription and monitoring parameters (such as the sampling interval, or data change filter) in newly added bindings to OPC-UA attributes.
• AttributeWriteParametersTemplate: OPC-UA write parameters (such as whether just the value should be written) in newly added bindings to OPC-UA attributes.

Templates have meaning only in the designer; they are not used in runtime.
