SAE J1939 Data Scanner Monitors Multiple PT1000 Inputs From A Diesel Engine
Axiomatic Technologies introduced their AX184200 20 PT1000 RTD scanner with CAN Bus (SAE J1939) connection. It features rugged packaging and watertight Deutsch IPD connectors for an IP67 rating. The system does not require additional programming or configuration. The scanner monitors 20 2-wire PT1000 inputs from a diesel engine and forwards the temperature information to the engine control [...]
NMEA Online & Virtual Installer Trainings July 13-15, 2021
NMEA (National Marine Electronics Association) offers their installer certification classes to the marine electronics world this July 13-15. These are 6-8 hour online instructor-led installer certification training sessions. The delivery method for the training is GoToWebinar, where students view and listen to the live instructor and presentation, along with being able to ask questions to [...]
Powertrain Diagnostics Platform For Engine Development Comes With Two CAN FD Interfaces
Kistler introduced its Kibox2, a modular and extendable powertrain diagnostics platform for engine development. The Kibox2 is equipped with two CAN FD interfaces for reading data from the vehicle network. The diagnostic platform is suitable for standard, electric, and hybrid powertrain analysis. It allows time- and angle-based data recording, real-time calculation of combustion parameters, limit value monitoring, [...]
Controller Area Network (CAN Bus) Tutorial - Message Frame Format
The following is an excerpt from A Comprehensible Controller Area Network by Wilfried Voss. This section will examine the exact structure of both data and remote message frames bit by bit. Per definition, a CAN data or remote frame has the following components: SOF (Start of Frame) - Marks the beginning of data and remote Frames Arbitration Field – Includes [...]
Low-Cost CAN Bus Monitor For Developing And Debugging High-Speed CAN Networks
Controller Area Network (CAN) is a serial network technology that was originally designed for the automotive industry, especially for European cars, but has also become a popular bus in industrial automation as well as other applications. The CAN Bus is primarily used in embedded systems, and as its name implies, is a network technology that provides [...]
Telematics Gateway Connects to Multiple SAE J1939 / ISOBUS Sensors
The CANUp telematics gateway by Technoton represents a multi-functional tool for advanced telematics systems combining data interface features, a digital-to-analog converter, and an online GPS/GLONASS tracker. The telematics gateway allows the easy and error-free implementation of a complex telematics system that uses many onboard smart sensors and devices to monitor multiple control points: fuel tanks, engines, upper [...]
Controller Area Network (CAN Bus) Tutorial - Higher Layer Protocols
The following is an excerpt from A Comprehensible Controller Area Network by Wilfried Voss. Even though highly influential in automobiles and small applications, the CAN Bus technology alone is not suitable for machine automation since its communication between devices is limited to only 8 bytes. Consequently, higher layer protocols such as CANopen for machine control, DeviceNet for factory [...]
Controller Area Network (CAN Bus) Tutorial - CAN Bus Controller Firmware
The following is an excerpt from A Comprehensible Controller Area Network by Wilfried Voss. As demonstrated in the image below, the ISO/OSI Reference Model specifies seven levels beginning with the physical connection to the actual user application, i.e., the Application Layer. The standard CAN implementation bypasses the connection between the Data Link Layer and the Application Layer to [...]
Controller Area Network (CAN Bus) Tutorial - Extended CAN Protocol
The following is an excerpt from A Comprehensible Controller Area Network by Wilfried Voss. The standard CAN message frame uses an 11-bit message identifier (CAN 2.0A), which is sufficient for use in regular automobiles and industrial applications but not necessarily for off-road vehicles. The Society of Automotive Engineers (SAE) Truck and Bus Control and Communications Subcommittee developed a [...]
Controller Area Network (CAN Bus) Tutorial - Remote Frame
The following is an excerpt from A Comprehensible Controller Area Network by Wilfried Voss. A Remote Frame requests the transmission of a message by another node. The requested data frame, identified by a unique message ID, may be accepted by any number of nodes in the network according to the individual application needs but can only be [...]
