IEC 62386-105:2024适用于通过电子照明设备的数字信号进行控制的控制装置和控制装置。通常，根据IEC 62386系列的总线单元包含固件。在某些情况下，在产品的生产或装运之后可能需要改变固件，例如，如果总线单元没有按预期操作。在这种情况下，经由接口的总线单元的固件更新是有益的。这个固件更新过程主要是一个错误修复过程，而不是一个功能扩展过程。然而，固件更新过程可用于功能扩展。但重要的是要详细考虑对整个系统产生负面影响的风险。这第二版取消并取代了2020年出版的第一版。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更: a)几个命令被修改、重命名和添加； b)变量已被修改和添加； c)增加了在紧急控制装置内实施的建议； d)区块验收的要求发生了变化； e)添加了示例工艺流程图； f)重新启动和上电的要求发生了变化。

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.
