Description: 具有互操作性的新一代电能表通信协议标准
DLMS用户协会基于面向对象技术提出了一种新的电能表通信协议DLMS/COSEM，它是目前唯一适用于不同制造厂家、仪表型号、通信信道并满足电能表全部应用的具有互操作性的通信协议。本文介绍了其概念、体系结构、实现互操作性的关键技术、一致性测试认证以及与其它通信协议的区别，并给出了应用实例。-interoperability of the new generation of electric meter communication protocol standards DLMS user associations based on object-oriented technology providers out a new electric meter communication agreement DLMS/COSEM. It is currently the only apply to different manufacturers, instrument models, Communication Channel Power Meter and meet all the application interoperability communication protocol. This paper introduces the concept, architecture, achieving interoperability of key technologies, conformance testing and certification with other communication protocol distinction, and an example of application is given.

Description: 电表在处理某一指令时，响应需要一定的时间，如果同时存在其他的重叠写入指令，可能引起电表自我保护，进入锁定状态。所以在程序设计中，应事先考虑电表响应某项指令，反馈数据所需要的最大时间长度（应与数据长度，串口传输速度有关）。-Meter in a treatment directive, the response to the need for a certain period of time, if at the same time there are other overlapping write instructions, may cause meter self-protection, to enter the locked state. Therefore, program design should be considered in advance of a meter in response to commands, feedback data required for the greatest length of time (should be consistent with the data length, the relevant serial transmission speed).
