Traditional Market Segments
Traditionally the biggest market segment for CAN nodes is automotive. Almost every passenger car manufactured in Europe has at least one CAN node - and drawing boards with future vehicles show 4 or more CAN networks operating in parallel in a vehicle to increase overall bandwidth and allow for up to 100 nodes to communicate via CAN.
The other big market segment using CAN is industrial control. Higher-layer protocols such as DeviceNet and CANopen bring CAN to the system integration level where system integrators can combine off-the-shelf components in a plug-and-play integration process. Typical off-the-shelf components include a variety of industrial I/O modules, including encoders, drives, pneumatic and hydraulic sensors and actuators. Both user organizations maintaining the higher-layer protocols also offer product catalogs online that list available off-the-shelf products. For CANopen products go to the product web pages of the CiA at www.can-cia.org and for DeviceNet products go to the products web pages of the ODVA - the Open DeviceNet Association - at www.odva.org.
