What is the B&R X67BC4321?
Fieldbus: CANopen
8 digital channels, can be configured as input or output
Simple I/O configuration via the fieldbus
Integrated connection to the local expansions via X2X Link for 39 additional modules
Configurable I/O cycle (0.4 to 1.3 ms)
CAN (Controller Area Network) has become considerably widespread in automation technology. CAN topology is based on a line structure and uses twisted pair wires for data transfer. CANopen is a higher-layer protocol based on CAN. This standardized protocol offers highly flexible configuration possibilities.
This bus controller makes it possible to connect X2X Link I/O nodes to CANopen . The bus controller has automatic transfer rate detection and AutoMapping of the I/O modules connected with X2X Link. All CANopen operating modes such as synchronous, event and polling modes are supported together with PDO linking, life/node guarding, emergency objects and much more.
