ISO/DIS 15765-2 Transport Protocol - CANoe DLL 1

1 Introduction

Efforts over the past several years to standardize diagnostic protocols and procedures internation-

ally have largely been completed with the introduction of the diagnostic protocol "Keyword Proto-

col 2000" (KWP2000) at all European automobile manufacturers and with the definition by

ISO/TF2 of a Transport Layer for diagnostic purposes (YAPTL or OSEK/COM 2.0).

The transport protocol standardized by ISO/TF2 is the basis for data transfer during diagnosis, but

is also used in other communication applications in which messages must be exchanged that are

larger than the transport capability of a CAN message. The purpose of the CANoe expansion DLL

described in this document is to model and simulate bus nodes which utilize this protocol.

Its implementation and specification are based on information of the following document:

• YAPTL - Yet Another Proposal for Transport Layer; Version 1.5; 06-04-97

• Releases from 3.0 implement the OSEK TP defined in the standard ISO/DIS 15765-2

(1999-11-30)

• Releases from 3.2 implement the OSEK TP defined in the standard ISO/DIS 15765-2

(2001-11-01)

• Releases from 4.1 implement the OSEK TP defined in the standard ISO/DIS 15765-2

(2003-11-11)

The version of the DLL described here is 5.0.0 (cf. 1.2 for details).

1.1 Abbreviations

Abbrev. Meaning

BS Block size, is defined by the receiver and transmitted to the sender in FC

CF Consecutive Frame

FC Flow Control

FF First Frame

SA Source Address (address of sender)

SF Single Frame: Transport layer message that fits into a single CAN message (6

(extended A.) or 7 (normal A.) data bytes)

Stmin Minimum interframe space, is defined by the receiver and transmitted to the

sender in FC

TA Target Address

TPCI Transport Protocol Control Information, is transmitted in Byte 0 (normal address)

or Byte 1 (extended address).

WFTmax The maximum number of consecutive wait frames the receiver sends before abort-

ing the transmission.

ISO/DIS 15765-2 Transport Protocol - CANoe DLL 2

1.2 New Features of DLL version 5.6

• It is possible to accelerate the sending of data by forwarding several CAN frames at once to

the CAN controller (default: 64). For details refer to section 3.1.5.

• To im

prove the precision for small timer values, please refer to section 6.

1.3 New Features of DLL version 5

• CANoe 5.0 or later is necessary now.

• There is an additional, alternative API allowing multiple TP connection in parallel and fur-

ther improvements. Please refer to CanTP_Manual.PDF for details.

• Transmission will abort with new error code 10 if an invalid FlowStatus value is received

in an expected FlowControl frame (cf. ISO/DIS 15765-2, section 7.5.5.3).

• It is possible to set the values of the J1939 ID fields for normal fixed and mixed (29 bit)

mode (cf. 3.1.3.4 for details).

• It is possible

to specify more precisely how the DLL reacts on CAN frame Tx timeout er-

rors (cf. 3.1.4). In addition, these errors are indicated to CAPL (cf. 3.2).

• The extended m

ode with freely assigned IDs (i.e. no base address) can now use extended

CAN IDs too.

• Fault Injection: It is possible to double a Consecutive Frame and specify the distance be-

tween the frames (cf. 7.3.1).

• Fault Injection: A fram

e can be dropped completely from a callback function (cf. 7.3.2).

• Fault Injection: Data tr

ansfers can be aborted at any time outside of a callback function (cf.

7.3.3).

1.4 New Features of DLL version 4.14

• The DLL reports its functions with more information in the CAPL browser selection dia-

log. In addition, the functions have been divided into two groups, one for normal and one

for fault injection functions.

• The extended (29 bit) CAN ID format is now fully available in normal and extended ad-

dressing modes. Note that a 29 bit base address for extended mode can only be set using

the CAPL function

OSEKTL_SetTpBaseAdr and that the usage of extended IDs has to be acti-

vated with the call

OSEKTL_UseExtId( 1);.

• It is possible to use a special ASDT (acknowledged segmented data transfer) mode exten-

sion. Please cf. to section 3.3 for details.

1.5 New Features of version 4.9

• First- and Single-Frames are also indicated in the OSEKTL_FI_PreSend callback (cf.7.3.2).

• In extended addressing mode, it is possible to specify a range of addresses for reception, in-

stead of using only the rx-mask (cf. 3.1.3.2,

OSEKTL_SetMsgCount()).
