Structs ¶ HEADER_TAG (Struct) PROTOCOL_DATA_UNIT (Struct) SERVICEHANDLER_PARAMETER (Struct)

HEADER_TAG (STRUCT) ¶ TYPE HEADER_TAG : STRUCT InOut: Name Type usHeaderTag UINT usHeaderLength UINT usServiceGroup UINT usService UINT ulSessionID UDINT ulServiceLength UDINT

PROTOCOL_DATA_UNIT (STRUCT) ¶ TYPE PROTOCOL_DATA_UNIT : STRUCT InOut: Name Type pData POINTER TO BYTE ulCount UDINT

SERVICEHANDLER_PARAMETER (STRUCT) ¶ TYPE SERVICEHANDLER_PARAMETER : STRUCT InOut: Name Type Comment ulChannelId UDINT Id of the channel on which the request arrived pHeaderTag POINTER TO HEADER_TAG Pointer to the header struct of the received request pduData PROTOCOL_DATA_UNIT References the request data (without header) pduSendBuffer PROTOCOL_DATA_UNIT Contains the buffer (pointer and length) for the reply data Result RTS_IEC_RESULT Result code; is used as inout parameter. When the corresponding event is posted, then this value is already pre-initalized with error code: - ERR_PENDING: Event was already posted before for the same received service request. The previous call returned ERR_CALL_AGAIN. - All other values (most likely ERR_L7_UNKNOWNCMD): Event for the received service request is posted the first time. Typical result codes, which should be returned by the event handler: - ERR_OK: Received service was completely handled. - ERR_CALL_AGAIN: Received service will be handled asynchronously. Event should be signaled again to poll the service reply. - ERR_L7_UNKNOWNCMD: Service is unknown by the event handler. - All other error codes: Runtime will send this result in a generic error tag as reply (or close the channel).
