"IEC60870-5-104是国际电工委员会(IEC)制定的一套通信协议标准,主要用于远动设备和系统的数据传输,旨在实现地理广域过程的监视和控制。该标准是IEC 60870-5系列的一部分,设计目标是确保兼容的远动设备之间的互操作性。IEC 60870-5-104规定了应用层(IEC 60870-5-101)与TCP/IP传输层的结合,允许通过不同类型的网络进行通信,如X.25、帧中继(FR)、异步传输模式(ATM)和综合服务数据网络(ISDN)。虽然标准中并未详细阐述,但其他IEC 60870-5配套标准(如IEC 60870-5-102)定义的ASDU(应用服务数据单元)也可以与TCP/IP结合使用。 这个标准不涉及安全机制,这意味着它不提供内置的数据保护或认证功能。中国也采纳了这一标准,并将其转化为国内标准DL/TXXXXX-XXXX,即“远动设备及系统 第5-104部分 传输规约”,等同采用了IEC 60870-5-104:2000的内容。这个标准自1995年以来不断演进,以满足电力系统(如EMS、SCADA和配电自动化系统)以及其他公用事业的需求。 IEC 60870-5标准分为5个部分,涵盖了传输规约的不同方面,包括传输帧格式、链路传输规则、应用数据的一般结构、应用信息元素定义和编码以及基本应用功能。在中国,还有一系列配套标准,如DL/T634、DL/T719和DL/T667,分别对应基本远动任务、电力系统电能累计量传输和继电保护设备信息接口。 IEC 60870-5-104的重要性在于它提供了标准化的方法来在远程设备和系统之间交换信息,这对于电力和其他公用事业的监控和控制至关重要。随着技术的发展,这些标准将继续更新以适应新的网络技术和安全需求。"

IEC 60870 part 5 [1] is one of the IEC 60870 set of standards which define systems used for telecontrol (supervisory control and data acquisition) in electrical engineering and power system automation applications. Part 5 provides a communication profile for sending basic telecontrol messages between two systems, which uses permanent directly connected data circuits between the systems. The IEC Technical Committee 57 (Working Group 03) have developed a protocol standard for telecontrol, teleprotection, and associated telecommunications for electric power systems. The result of this work is IEC 60870-5. Five documents specify the base IEC 60870-5: IEC 60870-5-1 Transmission Frame Formats IEC 60870-5-2 Data Link Transmission Services IEC 60870-5-3 General Structure of Application Data IEC 60870-5-4 Definition and Coding of Information Elements IEC 60870-5-5 Basic Application Functions IEC 60870-5-6 Guidelines for conformance testing for the IEC 60870-5 companion standards IEC TS 60870-5-7 Security extensions to IEC 60870-5-101 and IEC 60870-5-104 protocols (applying IEC 62351) The IEC Technical Committee 57 has also generated companion standards: IEC 60870-5-101 Transmission Protocols - companion standards especially for basic telecontrol tasks IEC 60870-5-102 Transmission Protocols - Companion standard for the transmission of integrated totals in electric power systems (this standard is not widely used) IEC 60870-5-103 Transmission Protocols - Companion standard for the informative interface of protection equipment IEC 60870-5-104 Transmission Protocols - Network access for IEC 60870-5-101 using standard transport profiles IEC TS 60870-5-601 Transmission protocols - Conformance test cases for the IEC 60870-5-101 companion standard IEC TS 60870-5-604 Conformance test cases for the IEC 60870-5-104 companion standard IEC 60870-5-101/102/103/104 are companion standards generated for basic telecontrol tasks, transmission of integrated totals, data exchange from protection equipment & network access of IEC101 respectively.
