CiA® 436 series: CANopen application profile for construction machines

The profile specifies the use of CANopen networks on construction machineries by introducing the virtual control architecture. The latter integrates the interfaces to the (diesel) engine control system, the drivers’ desk, the sensor control system, the transmission control system, the fleet management control system, and the implement (superstructure) control system. CiA 436-1 specifies the integration network with the interfaces to the mentioned sub-systems. For each sub-system a separate application profile is specified.

The idea for an integration network came from the rail industries. Unfortunately, the construction industries do not use such integration networks yet. Instead, normally the main controller is connected to all the networks. The currently valid CiA 436-1 version 1.1.0 is available since June 2010. The sub-network for sensor control systems is specified in CiA 415. Other CiA 436 parts specifying further sub-networks are in development.

Interested parties are invited to participate in development of further sub-systems.

The general physical layer definitions for CANopen devices (see CiA 301) apply. Compliant devices support bit rates of 125 kbit/s, 250 kbit/s, and further (optional). The 7-pin connector and the 5-pin micro-style (M12) connector with CiA 106 pinning are recommended for the CANopen network connection. An additionally defined application-specific 8-pin round connector does not comply with CiA 106. CANopen devices implementing this profile support the CANopen status and error LED (see CiA 303-3).

It is recommended that the CANopen NMT manager functionality resides on the device interfacing with the drivers’ desk control system. Other systems provide CANopen NMT server functionality. The node-ID assignment is manufacturer-specific. For node-ID assignment via CAN (e. g. for IP67-rated devices) the CANopen layer setting services (LSS, see CiA 305) may be used. The Heartbeat functionality is used for error control. Additionally to the reaction on a communication error and an internal device error, the reaction on a sub-network failure is configurable. The object 1000h indicates the type of the CANopen device and its functionality e.g. the generic construction machinery controller or the interface to a certain sub-system. This profile provides no PDO definitions, no special redundancy concepts, and no special mechanisms for safety-related data communication. If such functionalities are required, the definitions given in the corresponding documents (respectively CiA 301, CiA 302-6, and EN 50325-5) apply. The general device parameters contain the information about the used machine (type, manufacturer, serial number etc.), fleet management, superstructure (type and serial number), date and time as well as the operating hours.

CiA 301 version 4.2.0 CANopen application layer and communication profile
Scope

This specification specifies the CANopen application layer. This includes the data types, encoding rules and object dictionary objects as well as the CANopen communication services and protocols. In addition, this specification specifies the CANopen network management services and protocols. This specification specifies the CANopen communication profile, e.g. the physical layer, the pre- defined communication object identifier connection set, and the content of the Emergency, Time- stamp, and Sync communication objects.

CiA 302-6 version 4.1.0 CANopen additional application layer functions - Part 6: Network redundancy
Scope

The network redundancy is intended to be an add-on to the CANopen application layer and communication profile (see /CiA301/). It is assumed, that a CANopen device with the need of safety-critical and mission-critical communication can use all the features defined by the communication profile. Safety-critical and mission-critical communication is achieved by the underlying structure defined in this specification. The manufacturer and the system integrator shall take care, that the hardware and software of the CANopen device support the safety-critical and mission-critical function and that the CANopen device is operated within its safety-critical and mission-critical limits.

CiA 305 version 3.0.0 CANopen layer setting services (LSS) and protocols
Scope

This document specifies the layer setting services (LSS) and protocols for CANopen. These services and protocols are used to inquire or to change the settings of three parameters of the physical layer, data link layer, and application layer on a CANopen device with LSS slave capability by a CANopen device with LSS master capability via the CAN network. The following parameters may be inquired or changed: • Node-ID of the CANopen device; • Bit timing parameters of the physical layer (bit rate); • LSS address compliant to the identity object (1018h)

CiA 415 version 2.2.0 CANopen application profile for sensor systems in road-construction and earth-moving machines
Scope

The CANopen sensor system application profile for road construction and earth moving machines specifies the communication interface for sensors as well as the sensor control unit. The profile is suitable for a broad range of machine types (e.g. paver, compactor, grader, dozer, mill, heater and truck). NOTE The first version of this profile has been jointly developed with the OSYRIS (Open System for Road Information Support) consortium (www.osyris.org) and the European Asphalt Pa vement Association (EAPA).
