数字可寻址照明接口 第105部分：控制装置和控制设备的特殊要求 固件传输

[中文适用范围]： 本部分 IEC 62386 适用于通过数字信号控制电子照明设备的控制装置和控制设备。通常，根据 IEC 62386 系列的总线单元包含固件。在某些情况下，可能需要在生产或发货后更改固件，例如如果总线单元未按预期运行。在这种情况下，通过接口对总线单元进行固件更新是有益的。此固件更新过程主要设计为错误修复过程，而不是功能扩展过程。尽管如此，固件更新过程可用于功能扩展。但重要的是要详细考虑对完整系统的负面影响的风险。注：附录D提供了“固件更新管理检查表”以支持风险评估。 [外文原描述]： IEC 62386-105:2024 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62386-105:2024 applies to control gear and control devices for control by digital signals of electronic lighting equipment. Typically, a bus unit according to the IEC 62386 series contains firmware. There are circumstances where it can be necessary to change the firmware after production or shipping of the product, for example if the bus unit does not operate as intended. In such a case, a firmware update of a bus unit via the interface is beneficial. This firmware update process is primarily designed to be a bug fix process, not a feature extension process. Nevertheless, the firmware update process can be used for feature extensions. But it is important that the risk of negative effects to the complete system be considered in detail. This second edition cancels and replaces the first edition published in 2020. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) several commands have been modified, renamed and added; b) variables have been modified and added; c) recommendations for implementation within emergency control gear have been added; d) requirements for block acceptance have been changed; e) example process-flow diagrams have been added; f) requirements for restarting and power-on have been changed.
