CAN bus, the data link layer of
, can only transmit short packages consisting of an 11-bit id, a remote transmission request (RTR) bit and 0 to 8 bytes of data. The
standard divides the 11-bit CAN frame id into a 4-bit function code and 7-bit
node ID. This limits the number of devices in a
network to 127 (0 being reserved for broadcast). An extension to the CAN bus standard (CAN 2.0 B) allows extended frame ids of 29 bits, but in practice
networks big enough to need the extended id range are rarely seen.
is a communication protocol and device profile specification for embedded systems used in automation. In terms of the OSI model,
implements the layers above and including the network layer. The
standard consists of an addressing scheme, several small communication protocols and an application layer defined by a device profile. The communication protocols have support for network management, device monitoring and communication between nodes, including a simple transport layer for message segmentation/desegmentation. The lower level protocol implementing the data link and physical layers is usually Controller Area Network (CAN), although devices using some other means of communication (such as Ethernet Powerlink, EtherCAT) can also implement the
device has to implement certain standard features in its controlling software.
Different kinds of communication models are used in the messaging between
Those EDS files are mandatory for passing the CiA
conformance test. A free EDS checker is CANchkEDS.
The working group for the higher layer protocol CAN Application Layer (IG CAL) is inactive since many years. The one for the higher layer protocol
) is still active as well as the IG CAN FD (CAN with flexible data rate).
Special Interest Group (SIG) "Lift Control", which was found in 2001, develops the
application profile CiA 417 for lift control systems. The first version of CiA 417 was published in summer 2003. The version 2.0 has been available on CiA's website since February 2010. The SIG works on extending the features for
lift systems, improves technical content and ensures that the current legal standards for lift control systems are met. The version 2.1.0 was published in July 2012 and version 2.2.0 (available for CiA members) was published in December 2015 as Draft Standard Proposal. At the moment (2016) the SIG is working on version 2.3.0 (available for CiA members)
CANoe supports CAN, LIN, FlexRay, Ethernet and MOST bus systems as well as CAN-based protocols such as J1939,
, ARINC 825, ISOBUS and many more.
Different variants of CANoe are available. They differ in functional scope (full, run, pex), supported bus systems (CAN, FlexRay, etc.) and supported higher protocols (SAE J1939,
devices must have an object dictionary, which is used for configuration and communication with the device. An entry in the object dictionary is defined by:
, multi-byte parameters are always sent least significant byte first (little endian). The same is true for Ethernet Powerlink.
By means of
Communication Profile defined emergency error codes, the error register and device specific additional information are specified in the device profiles.
Some inclinometers provide an electronic interface based on CAN (Controller Area Network). In addition, those inclinometers may support the standardized
profile (CiA 410). In this case, these inclinometers are compatible and partly interchangeable.
devices are required to make the transition from the state Initializing to Pre-operational automatically during bootup. When this transition is made, a single heartbeat message is sent to the bus. This is the bootup protocol.
By using gateways, existing networks such as
, DeviceNet, or Profibus, can be integrated into the EtherCAT environment seamlessly. Furthermore, gateways provide a trip-free migration path from a traditional fieldbus to EtherCAT, reducing further investment costs.
PLC (Programmable logic controller) communicate using one of several possible open or proprietary protocols, such as EtherNet/IP, Modbus, Sinec H1, Profibus,
, DeviceNet or FOUNDATION Fieldbus. The idea to use standard Ethernet makes these systems more inter-operable.
CANalyzer is available in different variants. They relate to the software’s functional features (fundamental, expert and professional), supported bus systems (CAN, FlexRay, etc.) and supported higher-level protocol options (SAE J1939,
In a master/slave relationship, one
node is designated as the master, which sends or requests data from the slaves. The NMT protocol is an example of a master/slave communication model.
Actin software supports the following communication protocols for connecting the human operator (or autonomous agent software control system) to physical robotic hardware: Modbus, EtherCAT,
, Serial, Data Distribution Service, UDP, and TCP.
