SAE J1939 Data Acquisition System For Diesel Engines Measures And Records 23 Suspect Parameter Numbers (SPNs)

Posted by Industry News on

Titan S8-CAN by Madgetech (USA)

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 is suitable for 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 and Tier 4 diesel engines. Furthermore, it captures up to 23 of the 55 available SAE J1939 SPNs simultaneously. In addition, the data logger measures and records temperature, current, voltage, and pulse information. Thus, the tool is helpful for diesel technicians and fleet owners, allowing preventative and predictive maintenance of their vehicle fleets.

The all-in-one solution allows users to view and record data simultaneously without needing a PC or software for operation. The touch-screen user interface allows a comfortable device setup and configuration. The data logger stores up to 5 000 000 readings by utilizing an internal 1 GB memory. A data view from the current logging session is possible as a graph, tabular, or in real-time. The stored data can be viewed, copied, and deleted, and the user can add notes to logged sessions. The collected data can also be downloaded to a flash drive via USB, allowing continuous operation of up to nine hours with the help of an internal battery. The IP20-rated device measures 168.9 mm x 111.8 mm x 35.8 mm (6.7" x 4.4 " x 1.4"). A 16-pin OBDII connector and a nine-pin Deutsch connector are also available.

SAE J1939 Starter Kit And Network Simulator - Extended Edition

SAE J1939 Starter Kit And Network Simulator

Our JCOM.J1939 Starter Kit And Network Simulator is designed to allow the experienced engineer as well as the beginner to experiment with SAE J1939 data communication without the need of connecting to a real-world SAE J1939 network, i.e. a diesel engine.

For that reason, our JCOM.J1939 Starter Kit And Network Simulator consists of two SAE J1939 nodes, namely our JCOM.J1939.USB, an SAE J1939 ECU Simulator Board With USB Port. The board supports the full SAE J1939 protocol according to J1939/81 Network Management (Address Claiming) and J1939/21 Transport Protocol (TP).

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.

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 [...]

SAE J1939 Message Format And Interpretation Of PGNs

It happens on a regular basis that I am contacted by a user of our SAE J1939 ECU Simulator Board With USB Port, complaining that our device does not display a PGN correctly or modifies the PGN before transmitting. The real problem here is a misinterpretation of the PGN and its purpose. For instance, a PGN [...]

SAE J1939 Address Management Messages (Address Claim PGNs)

The following is an excerpt from  A Comprehensible Guide To J1939 by Wilfried Voss. According to  SAE J1939/81, network management procedures are used to “collectively manage the network”.While other higher layer protocols based on CAN Bus do not support dynamic node address assignments per default, the SAE J1939 standard provides yet another ingeniously designed feature to uniquely identify ECUs [...]

Guide To SAE J1939 - Parameter Group Numbers (PGN)

The following is an excerpt from A Comprehensible Guide To J1939 by Wilfried Voss. SAE J1939 is a very ingeniously designed protocol that takes a resourceful advantage of the CAN 29-Bit message identifier. Rather than relying on a myriad of protocol functions, SAE J1939 uses predefined parameter tables, which keeps the actual protocol on a comprehensible level. However, these parameter tables [...]
