| The above graphic illustrates how the test environment was built and what data gets transmitted. First to be able to simulate a CAN bus in a local environment PC1 runs [[https://www.peak-system.com/PCAN-FMS-Simulator-2.246.0.html|Peak System PCAN-FMS Simulator]] to generate CAN Frames based on the FMS Standard (supports FMS v 1.0 – 3.0). The generated frames are transmitted over [[https://www.peak-system.com/PCAN-USB.199.0.html|Peak System PCAN-USB]] into a Netmodule Router (NB2800 used in this example). Two example scripts on the router work with the incoming CAN traffic and send it back out over TCP, where [[http://sockettest.sourceforge.net/|SocketTest]] runs an PC2 as a simple TCP server. SocketTest is a tool based on Java that allows testing of UDP and TCP client and server sockets. In our case SocketTest is configured as a TCP server that is listening on Port 2000. | The above graphic illustrates how the test environment was setup and what data gets transmitted.
