Sevcon (USA) offers two CANopen products: Clearview, a digital display, and Smartview, an LCD display. The first display can either use the CANopen SDO protocol, or the CANopen PDO protocol.
CLEARVIEW IS A CONFIGURABLE CANOPEN COLOR DISPLAY, which can be set up to show a variety of information sent from the motor controllers. It can also be used to configure parameters on the controllers. It features a 3,5 inch, 320 pixel x 240 pixel, and 256 color display, a configurable main screen, auto bit-rate detection, and single and multi-node support. The employed CAN protocol is in accordance with CiA 301, the physical layer uses ISO11898-2 at bit-rates between 50 kbit/s and 1 Mbit/s. The display can acquire the data that it displays either using the CANopen SDO protocol, or using the CANopen PDO protocol. By default, the display will generate SDO upload requests for any data item displayed but if an RPDO has been configured on the display to handle that data item, then no SDO request will be generated, and the display will only show the data that has been received in PDO messages.
The device displays active faults and warnings and a historical fault log for faults on the motor controller system. It is flash programmable for display software updates and its calibrator functionality is available to provide vehicle performance adjustments (via password entry). It offers the option for OEM logo on power-up splash screen and displays driver input status signals (e.g. throttle, direction, handbrake, etc.), as well as system status information (e.g. motor temperature, battery voltage, motor current, etc.). The display has an operating voltage of 21 V to 28,8 V, an operating temperature between -20 °C and +50 °C, and a non-operation temperature of -30 °C to +70 °C. As user interface it offers 3-button keypad input. It weights 0,3 kg and offers an IP54 performance level.
The Smartview CANopen display is an extension of the company's range of dashboard mounted display products for battery-powered vehicles. The LCD gauge is compatible with any of the company’s CAN-based controllers. The product was designed with a sharp display for ease of reading and the hour count can be configured to show traction, pump or key-switch hours. The display offers a viewing angle of 180°, fault indication to aid troubleshooting, and the ability to manage planned vehicle maintenance via a pre-alarm and using two user configurable tool icons. The display is powered from the CAN network, thus eliminating unnecessary wiring and offers an IP65 rating. Ambient temperature ranges from -30 °C to +50 °C, storage temperature from -40 °C to +85 °C. As an option a backlit version is available.
