Highlevel Client Functionality¶
The following definitions are convenience functions making use of the standard OPC UA services in the background. This is a less flexible way of handling the stack, because at many places sensible defaults are presumed; at the same time using these functions is the easiest way of implementing an OPC UA application, as you will not have to consider all the details that go into the OPC UA services. If more flexibility is needed, you can always achieve the same functionality using the raw OPC UA services.
Read Attributes¶
The following functions can be used to retrieve a single node attribute. Use the regular service to read several attributes at once.
