Public Class OpcNodeAccessContext

Inheritance

Object → OpcNodeAccessContext

Derived types

• OpcBrowseNodeContext
• OpcFileNodeContext

Remarks

The OpcNodeAccessContext is used whenever a node based operation is performed using a specific OpcClient. An instance of this class does then provide the OpcNodeId of the node to operate on and the OpcClient to use for the operation.

Using this class or a scenario specific derivate of this class does simplify the API used for a specific node operation by reducing the amount of arguments (bound by the context object) they have to be passed.
