Description

The GetPdu term returns the raw byte stream data represented by a Request or a Response as seen on the physical layer. The GetPdu term is derived from ByteFieldTerm. A possible use case for retrieving raw communication data could be to implement bus tracing functionality. The corresponding opposite operation to the GetPdu term is provided by the SetPdu action.

A PDU as understood by the DiagCom extension comprises the complete payload of a message including the service identifier and any other request parameters. It does not include header or checksum bytes from underlying protocol layers.
