User Guide > 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).
The speed of the bus in bits/second within the boundaries below.
Type | Min | Max | Default |
---|---|---|---|
CAN | 1000 | 1000000 | 125000 |
LIN | 1000 | 20000 | 10000 |
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. Note! this will affect for example flows where this Bus is used. |
