SAE J1939 And The Challenging Migration From Classical CAN To CAN FD and CAN XL
The Society of Automotive Engineers (SAE) Truck and Bus Control and Communications Subcommittee has developed a family of standards concerning the design and use of devices that transmit electronic signals and control information among vehicle components. SAE J1939 and its companion documents have quickly become the accepted industry standard and the vehicle network of choice for off-highway [...]
Introduction To The NMEA 2000 Marine Networking Standard
NMEA 2000 is a marine networking standard created and administered by the National Marine Electronics Association (NMEA). The NMEA is an association of marine electronics manufacturers, dealers, and technicians. The NMEA 2000 standard describes a low-cost, moderate capacity, bi-directional, multi-transmitter, multi-receiver instrument network. Typical data on a network using this standard include position latitude and longitude, [...]
CODESYS Control For Raspberry Pi Allows PLC Programming According To IEC 61131-3
CODESYS is a PLC programming suite used by automation specialists as an environment for the development of controller applications. It is an IEC 61131-3 programming tool developed by the Germany-based company, 3S (Smart Software Solutions), providing users with integrated solutions that optimize the engineering of automated solutions. It represents a platform-independent development environment that is compatible [...]
CAN Bus Controllers Quickly & Easily Expand CAN Bus Networks For Machinery
E-T-A's flexible and compact SCS10, SCS20, and SCS30 CAN Bus controllers can plug into industry-standard vehicle sockets without additional wiring and configured using a graphical programming environment. In addition to defining CAN Bus messages, a large number of logical links and time functions are available. The SCS (Smart Control Systems) product group holds intelligent systems, power [...]
SAE J1939 Utilizes CAN Bus Message Collision During Bus Arbitration
SAE J1939 is a higher-layer protocol (HLP) based on Controller Area Network (CAN Bus). It provides serial data communications between microprocessor systems (also called Electronic Control Units - ECU) in any heavy-duty vehicles. Everything that has to do with the CAN Bus provides reliability with the maximum possible performance in mind, not only regarding required electrical robustness [...]
Quick Reference: Controller Area Network - CAN Bus - Versus Industrial Ethernet
At first glance, a comparison of the two networking technologies, Controller Area Network (CAN Bus) and Industrial Ethernet may appear as a battle between David and Goliath. On one side, you have the clear underdog, CAN Bus with its 1 Mbit/sec baud rate, its limited network length, and a maximum data length of 8 bytes per message. [...]
SAE J1939 Message Format And Interpretation Of PGNs
It happens on a regular basis that I am contacted by a user of our SAE J1939 ECU Simulator Board With USB Port, complaining that our device does not display a PGN correctly or modifies the PGN before transmitting. The real problem here is a misinterpretation of the PGN and its purpose. For instance, a PGN [...]
RobotDyn - Data Logger Shield For Arduino - Development Resources
To mention it upfront, we don't sell the data logger shield for the Arduino. As a matter of fact, I bought this board out of pure curiosity, because it fits and complements our Arduino-Based ECU Development Board With Dual CAN Bus Interface. This combination bares the potential for creating a low-price CAN Bus data logger.I was [...]
Tablet PC For In-Vehicle Networks Supports CAN Bus - SAE J1939 And Gigabit Ethernet Interfaces For IoT Applications
The X7R from Waysion Technology (China) is a 7-inch tablet PC designed to operate within truck in-cab and other applications within harsh environments.A CAN Bus interface maintains data communications via an extension cable, and it supports the 29-bit CAN-identifier. If required, the SAE J1939 higher-layer protocol can be implemented using an additional converter. The device receives data from CAN [...]
Vehicle Computer Architectures Help Improving Diesel Engine Performance And Lifetime Costs
Engineers are leaving no stone unturned in their unceasing drive to improve fuel economy, leveraging electronics, monitoring airflow, and using data from outside the vehicle. Computer architectures are being revised to simplify controls and decrease sensor counts, helping keep costs in line. Computers continuously monitor and control the engine, transmission, after-treatment systems, and more. Powerful devices [...]
