SAE J1939 Controller

SAE J1939 Controller In-Stock

Using SAE J1939, our HMI controllers can monitor critical engine metrics such as fuel and exhaust systems in heavy duty trucks, tractors, etc. They can also control large equipment such as cranes or cement mixers. These J1939 controllers are in-stock as most Horner automation controllers can run J1939 protocol. Our controllers, with 4 to 15" displays or screenless PLC options, users can get their most valuable assets back into operation quickly and cost-effectively. Additionally, our controllers are easy to install wherever your typical J1939 controller mounts. They can provide the critical engine monitoring data required for advanced equipment to operate safely and reliably.

J1939 Protocol Display Controllers for Combustion Engine Monitoring

J1939 Protocol is widely used as the network of choice for mobile equipment and just about any application involving a diesel engine. Our controllers, from Horner Automation, are some of the few industrial products that natively supports J1939. Our controllers unlock a whole host of monitoring and control capabilities. From backup generation, agriculture, marine, mobile equipment, as well as a host of other possibilities, we have your solution.

• high speed USB port for communication with PCs and programming of controller
• configurable serial protocols for communication to drives, PLCs, or other serial peripherals
• Full featured, built-in I/O including high resolution analog, thermocouple, RTD, high-speed counters, PWM outputs, relays, and much more! (varies by the Horner OCS model used)
• advanced high speed I/O capabilities
• optional communication add-on modules
• onboard Ethernet ports for Cscape programming as well as application defined communication with Auto MDI/MDI-X

SAE J1939 Controller

Our SAE J1939 enabled controllers are all-in-one automation controllers. Therefore, they can perform all machine functions in a unified hardware design: Logic Control, Operator Interface, I/O, and Networking. The high performance logic engine offers fast scan times solving user logic using Variable-based Advanced Ladder logic or the IEC 6-1131 language set. When it comes to speed, resolution, and technical capabilities, Horner OCS Controllers are leading the way. We have also developed some entirely new design techniques, a high functionality and flexible capabilities. Furthermore, our controllers have gained unprecedented acceptance across an array of commercial and industrial applications. In the market of fixed I/O, web-compatible controllers, our controllers leading the way.

J1939 protocol comes from the International Society of Automotive Engineers (SAE) and therefore works on the physical layer with CAN-high speed according to ISO11898. SAE J1939 defines five layers in the 7-layer OSI network model, which includes the CAN 2.0 specification. The application focuses on power trains as well as the chassis of commercial vehicles.

All J1939 packets contain eight bytes of data and a standard header which contains an index called PGN (Parameter Group Number), which embeds in the message’s 29-bit identifier. A PGN is a unique numeric identifier that associates with a specific parameter name. A PGN identifies a message’s function and associated data. For example, a PGN defines the parameter value a device is requesting or the parameter value that a device is sending.
