Controller Area Network (CAN Bus) - Physical Layer And Bus Topology
The following is an excerpt from A Comprehensible Controller Area Network by Wilfried Voss. The ISO/OSI Reference Model specifies seven levels starting with the physical connection up to the actual user application, i.e., the Application Layer. The standard CAN Bus implementation neglects the connection between the Data Link Layer and the Application Layer to save on relevant memory resources [...]
CAN Bus Over Ethernet Interface For Internet-of-Things (IoT) Applications
The EtherCAN HS by Kvaser is a real-time Ethernet-to-CAN gateway interface that, when connected over the Internet to an Ethernet-equipped PC, enables remote CAN Bus data access from anywhere in the world. The built-in Power-over-Ethernet eradicates the requirement for a separate power cable when it is not possible to power the device from the CAN Bus network. Kvaser's EtherCAN [...]
Galvanically Isolated CAN Bus Transceivers Protect Networks Against Destructive Energy
High noise levels on a CAN bus network have the potential to destroy CAN bus transceivers. This noise originates mainly from two sources, ground loops and electrical line surges.Protecting a network against this destructive energy requires the galvanic isolation of the CAN bus system from other local node circuitry. For more information on Controller Area [...]
SAE J1939 Address Management Messages (Address Claim PGNs)
The following is an excerpt from A Comprehensible Guide To J1939 by Wilfried Voss. According to SAE J1939/81, network management procedures are used to “collectively manage the network”.While other higher layer protocols based on CAN Bus do not support dynamic node address assignments per default, the SAE J1939 standard provides yet another ingeniously designed feature to uniquely identify ECUs [...]
Windows-Based Analysis And Test Environment For CAN -FD, LIN And Automotive Ethernet
CanEasy by Schleissheimer (Germany) is a Windows-based analysis and test system for CAN-FD, LIN and Automotive Ethernet. The tool simulates serial bus traffic, it provides a high degree of automation and is easily configured and extended with the support of plug-in modules. The goal is that users should focus on their task and not on their tools. CanEasy is a [...]
Arduino SIM Provides Easy Global Cellular Connectivity For Arduino IoT (Internet of Things) Cloud Projects
Arduino introduced Arduino SIM, a service solely for IoT (Internet of Things) devices based on the Arduino platform, providing developers and manufacturers cellular access to an IoT Cloud platform with a single data plan and competitive pricing. Arduino SIM strives to present a route to cellular IoT device development in a setting that is familiar to the [...]
CAN Bus And CAN FD Bit Rate Calculation App for iOS, Android, and Windows
Peak System, a manufacturer of Classical CAN Bus and CAN FD devices, has released its Bit Rate Calculation Tool for iOS, Android, and Windows.The free-of-charge application determines the register values of a Classical CAN Bus, CAN FD, or SJA1000 CAN Bus controller for user-defined CAN Bus and CAN FD bit rates. Furthermore, the results can be modified [...]
PC/104 Compliant Isolated Controller Area Network (CAN Bus) Peripheral Module
The PCM-CAN-2-ISO board by WINSYSTEMS is a PC/104-compliant, isolated Controller Area Network (CAN Bus) peripheral module.The board utilizes two NXP SJA-1000 CAN controllers with high-level features for use in automotive and industrial applications. The PCM-CAN card uses high-speed data isolation, transformer isolated power supplies, and custom logic to implement independent and user accessible isolated Control Area Network (CAN Bus) interfaces. [...]
