SAE J1939 is a standardized protocol that operates in CAN (Controller Area Network) bus networks. It is widely used in industrial diesel engines designed for the heavy-duty vehicle industry, including on-highway trucks, off-highway equipment, agricultural equipment, construction equipment, and other vehicles. Ordinarily, engine control units (ECUs) are used to control these kinds of devices, and more and more applications are employing PLCs for process automation to monitor the status of J1939-supported devices connected to an ECU.
During a project’s deployment, system integrators (SIs) must overcome several challenges, ranging from dealing with the complexity of different protocols and interfaces to spending too much time on pre-configuration and troubleshooting. With regard to these challenges, Moxa’s J1939 protocol converter is very easy to use and is equipped with a variety of maintenance functions to monitor the status of all connected CAN devices.
