The Start Method is used when a Client application wants to initiate/execute an/the operation of a FunctionalUnit. The Properties Argument can be used to provide an optional list of property values when initiating the operation. The listed items represent key-value pairs that conform to the OPC UA KeyValuePair core datatype. The qualified name provided via the key field must match the BrowseName of a Property member in the FunctionalUnit’s SupportedPropertySet.

The signature of this Method is specified below. Table 42 and Table 43 specify the Arguments and AddressSpace representation, respectively.

The Start Method should not be called by a Client with anonymous authentication.

Note: Results must be created between the start (calling the Start/StartProgram method or a manual start) and the end of a Program. So, the result must be complete before the ActiveProgram state machine transitions to the Complete state.
