Task
Read the access type of the OPC UA server.
Description
The access type of the OPC UA server is retrieved.
The OPC UA server can access variables via different methods. The default access method is IecVarAcc (ET_OpcUaAccessType.IECVARACC). Some variables can be accessed faster via direct memory access (ET_OpcUaAccessType.MEMORYACC). If the access type is set to memory access, the OPC UA server uses memory access where possible.
