System solution

Controlling 16 instruments

The VDO CANcockpit from Continental (Germany) is a system solution for processing data from various analog and digital sensors via a master instrument. It is capable of processing J1939 and CANopen data and can control up to 16 instruments via one master instrument.

VDO PRODUCTS CAN BE DEVELOPED IN A RANGE OF APPLICATIONS such as construction vehicles, agricultural and forestry equipment, stationary machines, sports cars, and boats. CANcockpit is the system solution for processing data from various analog and digital sensors via a central instrument connected to a CAN network. This instrumentation solution can be integrated into existing VDO panel solutions. The user can program the product with the company’s WIN-gauge software, which was developed for this product. It enables configuration of individual instruments or a complete series of instruments.

The product is also capable of processing two CAN protocols: J1939 and CANopen. It comes with DTC (diagnostic trouble code) handling of the protocol defined by J1939 through comprehensive functionality and setting options. Specific limits can be set and programmed so that an alarm is triggered when they are exceeded. The system is based around a central instrument, which can be either a tachometer or a speedometer. The central instrument features two CAN inputs supporting different CAN protocols, two frequency inputs, three resistive inputs, one 4-mA to 20-mA input, plus one 0-V to 5-V input. In addition, it is equipped with two switched outputs and a configurable digital display field.

Three sample applications are shown here:

1. Basic configuration

Sample requirements:
A generator fitted with a tachometer measuring up to 3000 rpm - there is only one CAN network; the limit values and settings are clearly defined.

Once the tachometer has been set up as the central instrument, the user has access to the desired tachometer display and the option of viewing other data, e.g. as part of an inspection routine, as and when required. The data can be displayed on the central instrument, allowing the user to monitor current engine data without the need for other satellite instruments.

2. Standard configuration

Sample requirements:
Instrumentation for a digger - a tachometer and four more instruments need to be added to a CAN network.

After the instrumentation solution has been programmed, key engine data such as coolant, engine oil, and transmission oil temperatures are displayed alongside rpm and operating hours, plus fuel level, giving an overview of the information.

3. Complex configuration

Sample requirements:
Safety requirements and different vehicle deployment scenarios (construction sites and public roads) often require complex configurations. One example is a mobile crane, the central instrument of which has to be hooked up to manage nine more instruments. All data comes from analog sensors and frequency sensors via a CAN network.

The instruments are connected and set, allowing a range of physical engine data to be displayed, as well as e. g. hydraulic data (CANopen). For the user, this means a maximum number of choices when it comes to putting together the required display instruments.
