CAN bus simulator software for Windows

What this CAN simulator software actually does

A CAN simulator is useful when the other controllers are not on the bench yet. CANsignal Suite opens a project, connects to Virtual CAN or to a supported adapter, and sends and receives Classical CAN frames. The current release is Classical CAN. CAN FD is planned and is not in this release.

The Start page is a project hub. From there you open a project, connect, import an EDS or DCF file, open the simulator, open the Object Dictionary, or open the documentation. It is not a live monitor. Live traffic is the job of Trace, the PDO monitor, and the graphs.

Virtual CAN needs no adapter. That is the path for a first check of node behaviour, signal generators, and a saved project before any hardware is connected. When the bench is ready, the same project can use a compatible USB-CAN adapter.

A CAN signal tool for generators and instruments

Signal generators and visual instruments sit on top of the bus activity. Text boxes are not limited by edition. Visual instruments are limited to 7 on the Trial, 15 on Light, and are unlimited on Professional.

Live Graphs plot values while the project is connected. Trace shows the frames. Together they are the CAN signal tool side of the suite: you generate a value, see the frame, and see the decoded signal without leaving the project.

Fault injection is available when you need a controlled bad case, such as a missing heartbeat or a value that should trip a diagnostic finding. The finding names the node and a next step. It does not invent a repair.

How a typical simulation session runs

Create or open a project. If you already have a device description, import the EDS or DCF so the Object Dictionary and PDO mapping have names instead of raw indexes. Connect to Virtual CAN if no adapter is plugged in, or pick the USB-CAN adapter channel if one is.

Add the nodes you need to imitate. Set the signals you want to move. Start the generators. Open Trace if you need the raw frames, or Live Graphs if you need the values over time. The PDO monitor shows the process data that is actually on the bus.

When the hardware arrives, disconnect Virtual CAN and connect the adapter. Keep the project. The point of the simulator is that the test setup does not have to wait for every controller to be present.

Editions, price, and the 28-day trial

Light is $800 once. Professional is $1,400 once. Both are one-time purchases, not a subscription. The Trial is 28 days and needs an internet connection for the session. Move is not in the Trial.

Professional adds the EDS validation, compare, quality, and compliance dashboard, device commissioning, Dashboard Builder, Python Studio, and CAN AI Offline and Online. Those tools are not in Light. Validation reads the file. It does not edit it.

The same Windows application is the product behind the CANopen® configuration pages, the EDS and DCF pages, and the diagnostic pages on this site. One licence, one project model, several ways to use it.

Limits worth knowing before you install

The simulator does not create hardware that is not there. Virtual CAN is a software bus inside the PC. Frames you generate are visible to the other nodes in that project. A controller that only exists on a physical connector still needs the adapter step, with a compatible USB-CAN adapter.

Instrument limits are part of the product, not a hidden cap. A Trial project can place 7 visual instruments, Light can place 15, and Professional has no instrument cap. Text boxes sit outside that cap on every edition. Values that do not fit on a gauge still belong in a text box or on Live Graphs.

Use the 28-day trial as the check. Open a project, connect Virtual CAN, run one generator, and open Trace. If that loop is the work, the CAN bus simulator fits. If the work needs CAN FD, it does not fit, because CAN FD is planned and is not in this release.
