Connecting to a Hardware Bus


The MxSuite can be connected to physical CAN or LIN buses. (If a bus is entirely simulated, it does not require a Device Interface Transform or hardware.) The procedure to connect to hardware is summarized as follows:

1.Install the Bus Interface Device and its drivers. Supported devices are listed here: Device Interface Transforms

2.Select the Device Interface Transform that supports your interface device (for example, a Vector CANcard requires a Vector Device Interface Transform).

3.Use the MxTransIt Toolbox put the Transform into your Harness window.

4.Use the Properties Box to configure the Transform. You can use the Help verb to link directly to the relevant topic. Note:

Select the DBC or LDF files that define your bus. The nodes in your test must be defined in this file.

Select the nodes to be simulated. If a node is simulated, it cannot be an operational hardware node on the same bus. (A node cannot be simulated and actual at the same time.)

A LIN bus must have one master node, either hardware or simulated.

5.Connect the Device Interface Transform to the simulated nodes. Nodes can be simulated with three kinds of Transforms:

Transmit and Receive Driver Transforms. See CAN Receive Driver, CAN Transmit Driver, LIN Receive Driver, or LIN Transmit Driver.

An MxVMC. See CAN Sub-System.

MxVDev Network Configuration. Network Configuration enables you to connect MxVDev (and its TestCases) directly to a bus.

6.In Project Settings, select RTClock.

Other features of the bus interface enable you to:

Switch on and off Automatic Transmission using the System Signal called MxV Auto Msg Tx.

Change the CAN bus configuration parameters on-the-fly using the System Signal called MxV Auto Msg Cfg.
