CiA 306 version 1.3.0CANopen electronic data sheet (EDS)
DescriptionThe usage of devices in a communication network requires configuration of the device parameters and communication facilities. CANopen defines a standardised way to access these parameters via the object dictionary. For handling of the complexity of CANopen systems software tools are required. This reduces the complexity of the planning, configuration and analysis process and significantly increases the security of the system. For this purpose software tools need an electronic description of the CANopen devices. To allow the usage of manufacturer independent tools, this document defines a standardised file format – called Electronic Data Sheet. Furthermore some derived file formats are specified. The Device Configuration File describes a concrete incarnation of a device configuration. The Module Data Sheet describes modules of devices with a modular structure.

CiA 308 version 1.0.1CANopen performance measurement basics
DescriptionCANopen is a field-bus protocol used in many diverse application: CANopen networks can be found not only in various industrial applications ranging from printing machines and robots to process controls, but also in ships, building automation, trains, trucks and even in coffee machines. CANopen is used for high accuracy drive synchronisation and for flight data recording. It is also in use in medical applications and has been chosen as the standard communication protocol for passenger information systems in public transport. This variety of applications leads to totally different requirements in regard to CANopen performance. The critical real-time requirement of one application may be a short response time to synchronisation messages relating to a single process data object, where as a different application may expect a node with many event driven process data objects to send these objects immediately after a certain input signal has changed. With drive synchronisation for instance, some applications need long time accuracy of the sync cycle and tolerate almost any jitter of a single sync message, and others require minimal jitter and tolerate long term drift. Regarding most other bus systems it is fairly straightforward to measure and publish communication performance figures for most node types. With CANopen this is not the case: the capability of CANopen to tailor the communication to the application needs makes it very difficult to determine valuable performance figures that are independent of the specific network set-up. For example, figures relating to reaction times not only depend on the processor used, but on the actual bus load, on the type of CAN controller being used, on the actual number and types of I/Os or drives connected, on the number and transmission types of the process data objects, on the guard or heartbeat cycle, and on many other settings and parameters in the object dictionary. Developing a CANopen node always involves a certain trade-off between performance and functionality. Therefore performance is a multi-dimensional value. The goal of this performance specification is to name and define a set of CANopen communication performance figures that may be used to compare devices and implementations within a specific application environment. It is not the aim of this paper to define a standard performance-measuring environment, as this would lead to implementations that perform fine in exactly this environment but disappoint under most other conditions. However, in order to establish some comparable conditions, this specification defines a number of standard busloads that may be used to simulate or enhance application environments. This performance test specification is aimed both at CANopen device developers and at CANopen system integrators. It may help developers determine relative performance figures regarding two implementation variants, thus leading to better devices and it may help system integrators to ask the right questions, thus leading to better CANopen networks.

CiA 801 version 1.0.0CANopen automatic bit-rate detection
DescriptionThis technical report describes the recommended practice and gives application hints for implementing automatic bit-rate detection in CANopen devices. With the Layer Setting Services (LSS) it is possible to change the bit-rate in CANopen networks. However, this mechanism fails in certain situations. Some low-cost devices that do not support LSS at all could also benefit from the recommended automatic bit-rate detection method. This technical report discusses an approach for automatic bit-rate detection in CANopen networks. As introduction the possible solutions to detect an unknown bit-rate for CAN controllers (Software / Hardware) are presented. The technical report will focus on situations where automatic bit-rate detection fails (no traffic on the bus, error frames) and how to avoid these deadlocks.

CiA 302-4 version 4.1.0CANopen additional application layer functions - Part 4: Network variables and process image
DescriptionIn a network programmable CANopen devices can be characterized as a process having input variables and output variables. The set of variables will be arguments of the program and hence will be only known in a final state when the program is written. The arguments are handled as variables located in the object dictionary. The marking of such parameters depends on the programming system (e.g. /IEC61131–3/) and does not fall into the scope of this document. But it can be assumed that there is a set of network variables with the logic attribute EXTERN. Compiling/Linking (or interpreting) a program including EXTERN variables requires relocation information. Within CANopen devices this information is the index (and sub-index) of the variable. Most of the programming systems know the mechanism of a resource definition. This can be used to assign the CANopen attributes (index, sub-index, R/W, assignment of CANopen data type to local data type etc.) to the corresponding symbolic names (variable name in the program). The resource definition may be created with a simple editor by the user or with much more comfort by a configuration tool. Systems with a disk- ased file system may exchange the information directly, e.g. via a device configuration file. The names of variables may meet the rules of the underlying programming system. The definition does not fall into the scope of this document. This is the responsibility of the programmer/manufacturer. Defining EXTERN variables requires a rule for distributing the indices. It is called "dynamic index assignment".

CiA 302-5 version 4.1.0CANopen additional application layer functions - Part 5: SDO manager
DescriptionCANopen offers a communication mechanism between CANopen devices via SDO. These communication channels are always established between two CANopen devices. For accessing a CANopen device the first time at least one SDO channel per CANopen device is required. This is called the default SDO channel. Only the SDO manager is allowed to use that SDO channel. Simple networks may use SDO channels that are pre-configured between a pair of CANopen devices. This allows direct communication between CANopen devices without the need of a SDO manager. This document defines mechanisms that may be used for plug-n-play networks, without the requirement of a pre-configuration of the network. These mechanisms may be used to establish dynamic SDO connections between CANopen devices. These mechanisms require a specific CANopen device in the network that is able to handle the dynamic request; this CANopen device is called SDO manager. These mechanisms require CANopen devices that are able to perform a dynamic request; these CANopen devices are called SDO Requesting Device (SRD).

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