CAN/LIN Bus

The Controller Area Network (CAN) and Local Interconnect Network (LIN) bus standards was designed to replace a steadily increasing need of copper cabling within vehicles and still allow Electronic Control Units (ECUs) and other nodes in their electrical architectures to communicate in a robust way. This is done by exchanging small data messages refered to as CAN and LIN frames that typically contain a number of signal values, each signal value being just a singel or a few bits wide.

To add a new Bus to your system model, click the LIN/CAN button in the Toolbar.

This will open the Bus dialog:

Another way of creating Buses is by connecting two CAN/LIN Ports directly to each other (as described in the Link chapter).

Bit Speed

The speed of the bus in bits/second within the boundaries below.

Type Min Max Default
CAN 1000 1000000 125000
LIN 1000 20000 10000

Actions

The following actions are available for existing Buses - right-click on a Bus in the topology or the tree view:

     
Edit Opens the Bus dialog in edit mode.
Delete Removes the Bus from the topology.
