Control Unit With Two CAN Bus Ports Supports CoDeSys Programming
Epec has released the Ec44 control unit, representing a new member of the Epec product. The controller comes in a new enclosure and a 46-pin Leavyseal connector with lever locking. The controller has a powerful 32-bit processor and large internal memory for application and parameters, two CAN Bus ports, Codesys 3.5 programming, and 16 inputs and outputs. The [...]
The Difference Between SAE J1939 And CAN Bus - The Extended CAN Bus 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 the use in regular automobiles and any industrial application, however, not necessarily for off-road vehicles.The Society of Automotive Engineers (SAE) Truck and Bus Control and Communications Subcommittee [...]
JCOM1939 Monitor Software - New Version 3.31.00
Our SAE J1939 ECU Simulator Board With USB Port allows any host device (e.g., PC) with a USB COM port to monitor SAE J1939 data traffic and communicate with the SAE J1939 vehicle network, which makes it also suitable to simulate SAE J1939 data traffic. The simulation of SAE J1939 signals (i.e., PGNs) is a [...]
SAE J1939 Data Monitoring And Simulation With The Arduino
The following is an excerpt from SAE J1939 ECU Programming & Vehicle Bus Simulation with Arduino by Wilfried Voss In general, there are three different intentions for connecting to a J1939 vehicle network: Mere monitoring, processing, and display of network data traffic. All functions as described under 1. but extended by the ability of sending data into the J1939 [...]
Controller Area Network (CAN Bus) - Error Detection And Fault Confinement
The following is an excerpt from A Comprehensible Controller Area Network by Wilfried Voss. The CAN standard utilizes a series of error detection mechanisms, which contribute to its high level of reliability and error resistance (see following Chapter - Error Detection). The reliability of CAN has been calculated in a mathematical model. Here is an example using the following [...]
SAE J1939 Transport Protocol (TP) Functions
The following is an excerpt from A Comprehensible Guide To J1939 by Wilfried Voss. Even though extremely useful in passenger cars and small industrial applications, CAN alone was not suitable to meet the requirements of truck and bus communications, mainly since its communication between devices is limited to only 8 bytes per message. However, it is possible [...]
Positioning Controller With CANopen - CiA-402 Capabilities
maxon has launched a miniaturized controller that comes in a size of 32 mm x 22 mm as part of its product line of positioning controllers.The controller's functionality, operation, software, and accessories are derived primarily from existing products in the EPOS4 range. The device is fitting for applications utilizing both brushed DC and brushless EC motors [...]
Universal Plug-in Module with I/O, CAN Bus, And CAN FD Interface
PEAK-System Technik has released its PCAN-MicroMod FD, a solution for the integration of a CAN FD interface and I/O functionality into custom hardware. Developers can plug the CPU module into their motherboard and configure it with the PCAN-MicroMod FD Configuration Windows software, which is included in the scope of delivery. The configuration data are transferred to [...]
SAE J13939 Data Recorder With Raspberry Pi Zero
Our jCOM.J1939.USB gateway board is a vehicle network adapter for SAE J1939 applications, which allows any host device with a USB COM port to monitor SAE J1939 data traffic and communicate with the SAE J1939 vehicle network.The board supports the complete SAE J1939 protocol according to SAE J1939/81 Network Management (Address Claiming) and SAE J1939/21 [...]
Arduino Compatible LIN Bus And CAN Bus Development Kit
LIN (Local Interconnect Network) is a serial network protocol used for communication between components in vehicles. The demand for a second serial network emerged as the technologies and the facilities implemented in modern cars grew, while the CAN Bus was too expensive to implement for every component in the car.The Arduino Compatible LIN Bus And CAN [...]
