Application Note: Transmitting Analog Signals Using the SAE J1939 Protocol
This post is part of our series on Utilizing SAE J1939 as a Higher-Layer Protocol for Industrial Automation. In short, the application I had in mind was to read an analog signal per one SAE J1939 node and transmit the data to another J1939 node where it controls the blinking frequency of an LED. This project is based [...]
SAE J1939 Starter Kit and Network Simulator - New Hardware Variant Using the ESP32 Processor
Our SAE 1939 Starter Kit and Network Simulators allow experienced engineers and beginners to experiment with SAE J1939 data communication without connecting to a real-world J1939 network, i.e., a diesel engine. To establish a network, you need at least two nodes. That fact applies, especially to CAN/J1939 nodes. A single CAN Bus controller will shut [...]
CAN Bus Development with ESP32-WROOM32 Development Board
This post will demonstrate how to add a CAN Bus port to the ESP32-WROOM32 development board, i.e., regarding hardware and software. Download this post as PDF... As a matter of fact, we already offer a hardware utilizing the ESP32 processor and an onboard CAN Bus transceiver as shown in the image to the left. The ESP32 WiFi, Bluetooth [...]
Embedded CAN Bus, SAE J1939, NMEA 2000 Development With ESP32
Like many businesses in the CAN Bus marketplace, we have struggled with the global shortage of electronic components. For instance, our SAE J1939 gateways are equipped with NXP processors, mainly the LPC1754 and LPC1768. Unfortunately, both processors are currently unavailable, and they come with remarkably long delivery times that go well into next year. We [...]
Position, Speed, Inclination Encoders With SAE J1939 And CANopen Interface
Siko (Germany) introduced their wire-actuated Pure.Mobile encoder family that measures position, speed, and inclination using an integrated single-axis inclination sensor. The encoders' sensor data utilizes serial protocols, including CANopen, CANopen safety, and SAE J1939. Mobile machines must always function precisely and efficiently, whether lifting platforms, mobile cranes or self-concrete pumps. Sensors are suitable for detecting the machines' movements, [...]
DIN Rail Ethernet to CAN/CAN FD Interface Supports SAE J1939, NMEA 2000, CANopen
Kvaser introduced their DIN Rail SE410S-X10 Ethernet-to-CAN(FD) multi-channel interface with additional I/O support through add-on modules.Kvaser supplies advanced CAN Bus solutions to engineers designing and deploying systems in areas as wide-ranging as trucks and buses, petrol-driven and electric cars, industrial automation, avionics, construction equipment, building automation, domestic appliances, marine, medical, military, railway, telecoms, textiles and more.The [...]
Multi-Turn SAE J1939 Encoders Enable Wear-Free And Maintenance-Free Operation
Turck, a specialist in sensor, Fieldbus, and connectivity, has added single- and multi-turn encoders with a solid or hollow shaft for mobile and agricultural machinery to its Industrial and Efficiency Line portfolio. The IP67-protected encoders are available in sizes 36 mm, 46 mm, and 58 mm. Two interlocked bearings guarantee a solid mechanical design and protect from [...]
SAE J1939 Data Acquisition System For Diesel Engines Measures And Records 23 Suspect Parameter Numbers (SPNs)
The Titan S8-CAN by Madgetech (USA) represents a data acquisition system for diesel engines that simultaneously measures and records 23 suspect parameter numbers (SPNs). The portable data logger suits engine, road, and diagnostic testing applications. It connects to an SAE J1939 network via the diagnostic port and supports the monitoring and recording of SAE J1939 messages between Tier 1 [...]
Design Of Proprietary Parameter Group Numbers (PGNs)
For a brief introduction to PGNs, see our post SAE J1939 Message Format and Interpretations of PGNs.As the name Proprietary Parameter Group Numbers implies, the SAE J1939 standard supports Parameter Groups in PDU1 and PDU2 Format that manufacturers can assign for their specific needs, which includes the design of the data field in the message. [...]
SAE J1939 Data Traffic Generator For Diesel Engine Network Simulation
I am writing this post to respond to multiple inquiries from newcomers to the SAE J1939 technology. Most questions are like, "Can your device simulate any PGN, for instance, engine speed in rpm?" or "Can your device simulate a 2014 Tonka Flex diesel engine?" The short answer is yes, but things are a bit more [...]
