When the application/SW-C is instantiated for many times, each instance will obtain a globally unique session ID. An application/SW-C can have several log/trace sessions simultaneously (via multiple opened Dlt ports). AUTOSAR does not specify the session ID for SW-C, so the parameter values defined by port should be used.

简介 Introduction¶

DLT模块为使用者提供了通用的日志和跟踪记录消息功能。该模块可接收来自DET（默认错误跟踪器）、DEM（诊断事件管理器）、软件组件（SW-C）的日志信息，以及来自RTE的跟踪信息。DLT模块通过通信总线传输这些数据，使外部可观测ECU的运行信息。

The DLT module provides universal log and trace message recording functions for users. This module can receive log information from DET (default error tracker), DEM (diagnostic event manager), software components (SW-C), as well as trace information from RTE. The DLT module transmits the data via communication bus, making it possible to observe the operation information of the ECU externally.

此外，该模块可选择通过NvM（非易失性存储器）模块持久化存储更新后的DLT过滤器设置。此功能使得ECU在每次启动时，无需接收显式设置请求，即可直接按预设级别传输日志/跟踪信息。

In addition, the module can store the updated DLT filter settings permanently via the NvM (non-volatile memory) module. With this function, the ECU can transmit log/trace information directly at the preset level without receiving explicit setting requests during each startup.

Dlt_AUTOSAR_Architecture — Figure caption goes here.¶

如图 Figure caption goes here. 所示，在软件架构层级中，DLT模块位于PduR之上，并处于RTE之下。该设计实现了通信协议与上层应用间的解耦，确保日志传输机制的高效性和可配置性。

As shown in the figure :ref: Dlt_AUTOSAR_Structure, in the software architecture level, the DLT module is above PduR and below RTE. Such design allows the decoupling between communication protocols and upper layer applications and ensures the efficiency and configurability of log transmission mechanism.
