2.3. Key Transport Protocols Used by DTS Monaco

DTS Monaco supports several transport protocols, each with its own strengths and applications. Key protocols include:

• ISO-TP (ISO 15765): A widely used standard for transporting diagnostic data over CAN.
• UDS (ISO 14229): An advanced diagnostic protocol that builds upon ISO-TP, offering enhanced features for ECU communication.

3. ISO-TP (ISO 15765): The Foundation of Data Transfer

ISO-TP, or ISO 15765, is a crucial transport protocol that enables the transfer of diagnostic data over CAN. It provides mechanisms for segmenting large data payloads into smaller CAN frames and reassembling them at the receiving end.

3.1. Overview of ISO-TP

ISO-TP defines how data exceeding the 8-byte limit of a standard CAN frame is split into multiple frames for transmission. It also specifies how these frames are reassembled into the original data packet at the destination. According to the ISO standard, ISO-TP supports both segmented and unsegmented data transfer.

3.2. Message Segmentation and Reassembly

The segmentation process involves dividing the large data payload into smaller segments, each fitting within a CAN frame. Each segment is then transmitted with appropriate header information indicating its position in the overall message. The receiving ECU reassembles these segments based on the header information.

3.3. Flow Control Mechanisms

ISO-TP includes flow control mechanisms to manage the data transfer rate and prevent buffer overflows. These mechanisms allow the receiving ECU to signal when it is ready to receive more data, ensuring reliable communication.

4. UDS (ISO 14229): Advanced Diagnostic Services

UDS, or ISO 14229, is an advanced diagnostic protocol that builds upon ISO-TP. It provides a standardized set of diagnostic services and extends the capabilities for ECU communication.
