CAN interface for FMS Introduction

Introduction This document contains information on the FMS standard, which is an open common interface produced by many manufacturers of rigid trucks. FMS 2.0 is also supported starting in May 2011.

More information on the FMS standard can be found at www.fms-standard.com.

Scania's FMS interface is referred to in this document as RTG, and the bodybuilder links their own FMS network to the control unit via a connector. • Up to and including January 2009, the connection was made via connector C471 • From February 2009 onwards, the connection is made via connector C137 Chassis serial number limits for the different connections are indicated later in this document. IMPORTANT! No other connector or other CAN bus may be connected. An incorrect connection could cause the normal functions of the rigid truck to behave irrationally. The rigid truck may even stop and need to be towed.

CAN interface for FMS Requirements for CAN communication with the vehicle

Requirements for CAN communication with the vehicle This section lists the requirements for CAN communication with the RTG control unit on the external CAN bus. SAE J1939 forms the basis of the protocol, but large parts are not implemented. These parts are SAE J1939-81 (Network Management), large parts of SAE J1939-73 (Diagnostics) and parts of SAE J1939-21 (Data Link Layer).

SAE J1939-81 Network Management The address space in a Scania vehicle is static. Because of this, there is no need for the Network Management described in SAE J1939-81. • Fixed addressing is used in accordance with Preferred addresses for Industry group 0, Global and Industry group 1, On-highway Equipment. • Source addresses for equipment which does not normally belong to the vehicle follow the requirements in J1939, ISO 11992 or OBD/EOBD.

CAN interface for FMS Requirements for CAN communication with the vehicle

SAE J1939-21 Data Link Layer SAE J1939-21 defines five message types: • • • • •

Commands - Not supported. Requests - Not supported. Broadcast/Response - All available information is sent periodically. Acknowledgement - Not supported. Group Functions - Proprietary messages och Multipacket messages, TP.CM, TP.DT, are supported.

Note: According to section 5.2.1 SAE J1939-21, revised version July 1998, priority bits in message identifiers must be filtered out and ignored by the receivers.

General guidelines • Control units connected to a CAN bus must be able to handle up to 100% CAN bus load with the correct messages with no significant functional limitations or malfunctions. • The CAN bus load should not generally exceed 80%. • Avoid closing control loops over the CAN because the guaranteed access time is relatively long and fast control loops require a lot of bandwidth. If closed control loops over the CAN are still required, then they must be fully capable of sending the necessary CAN messages using only half the transmission frequency. IMPORTANT! The bodybuilder is responsible for ensuring that the external CAN bus is used correctly.

CAN interface for FMS Connectors and cables

Connectors and cables • Scania does not use SAE J1939 connectors. • Scania uses twisted pair cables (twisted 40 times per metre) with no shield or sheath. The electrical properties (resistance, impedance, capacitance etc.) are defined in SAE J1939-15 Physical Layer Light. • Scania uses a cross-section of 0.75 mm2 for cables inside the cab and 1.5 mm2 on the frame. CAN connectors (and ECU pins) outside the cab should preferably be gold-plated. • The following colours and markings apply to the external CAN bus cables: CAN_H must be blue and CAN_L must be white. In order to avoid misunderstanding it is important that the cables retain their colour for the lifetime of the vehicle. CAN low should be marked as CAN_L and CAN high as CAN_H.

The figure shows the principle of the external FMS network topology.

<3m

• The length of the cables must not exceed 30 metres (main cable) between the connector in the truck and the control unit with the other termination resistor. • If more than one control unit is connected, the length of the cables between the main cable and control unit should not exceed 3 metres. • The cables should be as short as possible to minimise the effect of electromagnetic interference. • The number of control units in the external FMS network should not exceed 9.

CAN interface for FMS Termination resistors

RTG CAN High

Depending on the other control units connected to the CAN bus, there must be a 120 Ohm termination resistor in the control unit which is connected to the FMS interface for bodybuilders. If the control unit is not equipped with an internal termination resistor, an external termination resistor must be connected as close to the control unit as possible (see illustration).

CAN interface for FMS Termination resistors

Termination of an external CAN bus So that CAN communication can work without interference, there must be a 120 Ohm termination resistor at each end of the CAN bus. Check that there is a termination resistor at each end of the CAN bus using a multimeter. The resistance should be 60 Ohm (two 120 Ohm resistors connected in parallel). A number of different systems can be connected to the cable harness of the external CAN bus. Certain systems have a built-in termination resistor and others are unterminated. The table shows when there is to be a termination resistor in connector C137 or in the control unit connected to C137.

CAN interface for FMS Fault validation of communication (Time-Out)

Fault validation of communication (TimeOut) Avoid CAN communication when the starter key is in the lock or radio positions. Also avoid CAN communication during the start sequence of the control units connected to the external CAN bus. During normal operation, when the starter key is in the drive position, a message should not be validated as missed (time-out) until at least 5 times the message period time. A longer fault validation time is permitted. During the engine start sequence, when the starter motor is turning, the supply voltage can be extremely low. Because of this, communication from the RTG control unit cannot be guaranteed during this sequence. For this reason, no fault codes related to CAN communication with the RTG control unit should be set when the system voltage is under 18 V. When the starter key is turned to the drive position, the RTG control unit starts sending messages within 10,000 ms. A message sent from the FMS control unit cannot be considered missed until after 10,000 ms + 5 x the message period time. Example: If a message has a period time of 100 ms it cannot be considered missed until after 10,000 + 5 x 100 = 10 500 ms. Longer fault validation times are permitted.
