CAN crisscross

For over 25 years, Add2 has provided solutions and services to automotive, aerospace, and process controls clients. Their portfolio includes a range of Classical CAN-related product families.

The CAN Newsletter already reported about the English company’s Visualconnx visualization and control software which allows engineers to build PC interfaces for real-time systems, and link them to real-time systems over CAN. But Add2 also provides other CAN products.

Microgen is an electronic control unit (ECU) prototyping system. It can function as a CAN gateway for communications and discreet I/O, a rapid control prototype target for use during model-based design, or a configurable test interface. With its physical layer support for five CAN, two LIN, and 56 flexible I/O channels, the product is programmed for a multitude of control or test development tasks, and is suitable for use in the lab or in-vehicle. Other commonly used protocols can also be integrated, allowing the device to convert incoming information in a wealth of protocols for onward transmission, broadening compatibility between disparate systems.

Genix, a range of rack-based and distributed hardware-in-the-loop (HIL) products allow the simulation from single signals to full vehicle, using CAN as one form of I/O. For the Genix series special purpose modules are available including CAN switch with fault insertion. It provides 4 x 8-channel CAN multiplexor with fault insertion capability.

Another product is the Sens-X in-fuse vehicle current measurement system that outputs measurement data over CAN for further analysis. Using a pre-configured graphical user interface (GUI), each smartfuse in a system can be monitored and configured to stream its data onto CAN. This data can be analyzed and manipulated in the supplied GDSP GUI, which is hosted in the real-time interface creation software Visualconnx, introduced at the beginning of this article. A trial of the GDSP GUI is supplied with each system purchased. The sensors measure currents, voltages, and transients at levels from over 1000 A to sub-mA, and can stream data onto CAN. The system can support up to 100 sensors per CAN segment and offers a rate of up to 1000 samples per minute. Noise levels approximate to 0,002 % of the rated current. This allows for diagnosis of quiescent current issues.

The LVT-PSU is a CAN-controllable power supply unit. It allows extending the capabilities of a system through the control of available test power via automated means.

Last but not least, the Commdongle CAN/USB interface adapter tool for CAN interfacing, logging, and analysis. It was designed for test development engineers or students working in vehicle controls systems and support one or more CAN communications buses. The device can be used as a standard CAN/USB interface via a PC to analyze individual CAN messages using the company’s CANsurf software tool. Also for advanced CAN analysis, Visualconnx or the user’s own software via APIs can be used. The product offers full galvanic isolation and logging of multiple CAN buses at speeds of up to 1 Mbit/s. So, the adapter used across automotive and aerospace, facilitates sending, receiving, monitoring, and logging messages on the CAN network.
