TransferToDevice initiates the transfer of offline configured data (Parameters) to the physical device. This Method has no input arguments. Which Parameters are transferred is based on Server-internal knowledge.

The Server shall ensure integrity of the data before starting the transfer. Once the transfer has been started successfully, the Method returns immediately with InitTransferStatus = 0. Any status information regarding the transfer itself has to be collected using the FetchTransferResultData Method.

The Server will reset any cached value for Nodes in the online instance representing Parameters affected by the transfer. That way the cache will be re-populated from the Device next time they are requested.

The signature of this Method is specified below. Table 54 and Table 55 specify the arguments and AddressSpace representation, respectively.
