Simulation system tests CiA 447 devices

Esacademy’s (Germany) CANopen CiA447 simulation system can be used for testing CiA 447 devices without requiring the real automotive gateway ECU. It consists of a gateway simulation, a universal controller device, and a roof bar light and sound device.

THE GATEWAY SIMULATION IS BASED ON THE SAME SOFTWARE that is used in the gateways of various automotive manufacturers. To function properly, this software requires one Peak CAN interface and at least one connected CiA 447 device. It allows CiA 447 compatible devices to access a car’s data and dashboard components (buttons, displays). The simulation can also replay tours, which are simulations of driving along a specific route. The tour data includes engine and location (GPS) data.

This simulation is a general-purpose application for controlling of specific types of nodes on a CiA 447 (car add-on devices) network. For example all inputs and outputs of an I/O module can be controlled, along with blue light flashers, roofbars, sound, and other virtual devices. The controller operates as a simulated node with a controller virtual device. It participates in LSS and is assigned a node ID by a CiA 447 gateway. Once the controller is running it continually looks for nodes appearing on the network and displays them in the network window. The controller can send wakeup messages and object to sleep requests, allowing for sleep/wake management testing. Once a node is detected its functionality can be accessed allowing detailed testing. Additional CiA 447 virtual devices can be added on request and by the user. Existing virtual device support can be user-customized. The tool includes one year of free updates to the current version.
