数字可寻址照明接口第105部分:控制装置和控制装置的特殊要求固件传输

[中文适用范围]： 本文档规定了数字寻址照明接口（DALI）中镇流器和控制设备的固件传输的具体要求。该标准适用于包含固件的总线单元，用于在生产或运输后更改固件，例如当总线单元未按预期运行时。固件更新过程主要用于修复错误，也可用于功能扩展，但需详细考虑对完整系统的负面影响风险。 [外文原描述]： IEC 62386-105:2020 applies to control gear and control devices. Typically, a bus unit according to IEC 62386 (all parts) contains firmware. There are circumstances where it might 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 is considered in detail.
