SAE J1939 vs. CAN Bus - What's the Difference?
To say it upfront, the difference between SAE J1939 and CAN Bus (Classical CAN and CAN FD) has all to do with so-called "Higher Later Protocols (HLP)," and SAE J1939 is one of them. I have written a post about HLPs (see: Guide to SAE J1939 - CAN Bus Higher Layer Protocols), but I would like [...]
CAN FD Data Logger For CAN Bus Monitoring, DBC Logging, Message Filtering, SAE J1939 Logging, And Trigger Events
Influx Big Data Solutions introduces their ReXgen 2 CAN Bus logger, one of the smallest, compact, robust, and powerful handheld CAN Bus data recorder available in the market today. The device is targeted at applications requiring CAN 2.0 and CAN FD data recording capabilities. The data logger comes with a freely distributable ReXgen data logger configuration [...]
Telematics Gateway With SAE J1939 Data Logging For Predictive Maintenance Of Diesel Engines
The Telematics Gateway from iWave represents a vehicle diagnostics system for monitoring critical vehicle parameters from any place. The device supports four CAN Bus interfaces, including CAN FD, and is suitable for heavy-duty trucks, off-road vehicles, emergency vehicles, and vessels.The gateway utilizes parameters such as location, working duration, engine performance, and engine parameters that require continuous [...]
Multi-Functional Telematics Gateway Processes SAE J1939, ISOBUS Parameters For Predictive Maintenance
The CANUp telematics gateway by Technoton represents a multi-functional telematics unit for use in advanced machinery telematics systems. Advanced machinery includes mobile and stationary objects, which have many operation monitoring parameters for engines, power generators, boilers, various additional equipment, and other assemblies. The core features of the CANUp telematics gateway include: Reading over 10,000 machine operation parameters, thus the [...]
CAN Bus, SAE J1939, NMEA 2000 Programming With ESP32, Supporting USB, Bluetooth, BLE, And WiFi
The ESP32 Series of modules by Espressif supports the integration of WiFi, Bluetooth, and Bluetooth LE for a wide range of applications, most prominently for IoT (Internet of Things). For instance, using WiFi ensures connectivity within a large radius. Using Bluetooth allows the user to easily detect (with low-energy beacons) a module and connect it to [...]
Telematics Gateway For Automatic SAE J1939 and ISOBUS Scanning and Parsing
The CANUp telematics gateway by Technoton couples the functionality of two vehicle data interfaces, a digital-to-analog converter and an online GPS tracking device. The gateway scans and automatically parses 10 000 SAE J1939/71 and ISOBUS parameters and transmits selected data to a web-based telematics server or by email/SMS to a user. It applies edge computing algorithms for onboard [...]
Guide to SAE J1939 - Parameter Group Number Compilation
The following is an excerpt from A Comprehensible Guide To J1939 by Wilfried Voss. For internal purposes, the parameter group number is extended to 24 bits = 3 bytes, where the most significant 6 bits are always set to zero. Each ECU must accomplish this process individually; this procedure is not part of the CAN standard. To compile [...]
Guide to SAE J1939 - Transport Protocol (TP) Message Packaging and Reassembly
The following is an excerpt from A Comprehensible Guide To J1939 by Wilfried Voss. Certain parameter groups may require more than the eight data bytes supported by the CAN standard. The SAE J1939 standard, namely the Transport Protocol Function, supports message lengths up to 1785 bytes. If a program group requires more than eight data bytes (9…1785 bytes) and [...]
CAN Bus Bolt Connects Industrial Machinery And Devices to Wireless Networks, WiFi And Bluetooth
HMS Networks introduced its Anybus Wireless Bolt CAN gateway, providing CAN Bus communication via WiFi or Bluetooth. The device builds on the success of Anybus Wireless Bolt, which is applied to wireless Ethernet access. Like its predecessor, the gateway for bolt-on-machine mounting is suitable for heavy-duty machinery and demanding industrial applications. Applications include warehouse installations and AGVs (Automated [...]
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 [...]
