The controller area network protocol (ISO 11898) for serial bus networks is designed
for the interconnection of smart devices (from multiple manufacturers) in smart
systems for real-time industrial applications. CAN multi-master systems ensure high
data integrity through the implementation of broadcast messaging and advanced
diagnostic mechanisms. Originally developed for use in automobiles, CAN is now
used in a variety of industrial automation control environments.
CANmotion is a CANopen-based motion bus with an additional mechanism that
provides synchronization between the motion controller and the drives.
CANopen is an open industry-standard communication protocol and device profile
specification.
The continuous function chart (an extension of the IEC61131-3 standard) is a
graphical programming language that works like a flowchart. By adding simple
logicals blocks (AND, OR, etc.), each function or function block in the program is
represented in this graphical format. For each block, the inputs are on the left and
the outputs on the right. Block outputs can be linked to inputs of other blocks in order
to create complex expressions.
CAN in automation is a non-profit group of manufacturers and users dedicated to
developing and supporting CAN-based higher layer protocols.
When the common industrial protocol is implemented in a network’s application
layer, it can communicate seamlessly with other CIP-based networks without regard
to the protocol. For example, the implementation of CIP in the application layer of an
Ethernet TCP/IP network creates an EtherNet/IP environment. Similarly, CIP in the
application layer of a CAN network creates a DeviceNet environment. In that case,
devices on the EtherNet/IP network can communicate with devices on the
DeviceNet network through CIP bridges or routers.
