Nitro CAN Master

CAN-Bus Simulator is an engineering product that can be used for development purposes and provides simulation of log files taken via the OBD port with the TP1 standard.

Understanding and analyzing in-vehicle communication networks plays a critical role in making vehicles more efficient and safer in the automotive industry. Nitro CAN Master software can process and simulate Controller Area Network (CAN) data logs obtained via the On-Board Diagnostics (OBD) connector in accordance with the Transport Protocol 1 (TP1) standard. This process is vital for correctly monitoring, diagnosing and optimizing vehicle systems.

CAN-Bus is a communication protocol widely used in the automotive sector and enables different electronic control units (ECU) in the vehicle to communicate with each other. The OBD connector provides a standard interface for data access over the vehicle’s CAN-Bus system. This article covers decoding and simulating CAN log files taken via OBD in accordance with the TP1 protocol.

CAN-Bus and OBD Connector

CAN-Bus is a two-wire network for data transmission and the OBD connector provides access to this network. OBD is generally used for diagnosing vehicles and reading fault codes. Data obtained through this connector contains important information for communicating with vehicle control units and diagnosing them.

TP1 Protocol

TP1 is a communication protocol that defines how CAN data packets are segmented and reassembled. This protocol enables large data blocks to be transmitted effectively over CAN-Bus. TP1 is especially required for correctly transmitting and receiving long messages.

Simulation Software

The simulation software discussed in this article processes and simulates CAN log files taken via OBD according to the TP1 standard. The software analyzes the CAN data stream in real time and performs TP1 message segmentation and reassembling. This simulation enables better understanding of vehicle systems and more effective understanding of information on the CAN bus.

This simulation software can be used by automotive engineers and technicians for deeper analysis of vehicle systems. It is also an important tool for automotive  equipment for monitoring, diagnosing and improving vehicle communication performance. Thanks to its TP1-compliant data processing and analysis capability, the software contributes to a more effective understanding of CAN-Bus data transmission.

How Does Nitro Master CAN Work?

Nitro Master CAN is a reverse-engineering software that lets you decode and interpret CAN-Bus communication data on OBD. After analyzing CAN data recorded via OBD, the software performs data decoding and  it resequences according to the TP1 protocol. Simulator mode mimics all decoded data in the recording as question-and-answer and returns the answers decoded from the recording completely for every query in that recording. The software automatically calculates message lengths and prepares to answer queries coming from the CAN line in real time. All prepared data can be changed instantly as desired. Changed data is reflected immediately to the CAN line in simulator mode and responses can be monitored in real time as long as the message flow continues.

Thanks to the software’s mimic and flexible data-modification capability, you can decode algorithm-based data on the OBD line. By changing sensor data as you wish, you can reverse-engineer sensor value formulas. By observing product data converted into both Hexadecimal and ASCII formats, you can easily decode vehicle diagnostic information messages. Using the random message mode in the simulator, you can continuously and automatically change values of all messages belonging to a defined data-read address, observe changes in message output, and run performance tests on products connected to Nitro Master CAN.
