IEC61850标准是基于通用网络通信平台的变电站自动化系统唯一国际标准，代表了变电站自动化的未来发展方向，它用面向对象的思想来描述变电站IED（智能电子设备）之间的通信协议，基于TCP/IP的制造报文规范MMS是IEC61850标准中特定通信服务映射SCSM的核心通信协议站，本文主要介绍了IEC61850的概况和数据模型，并详细描述了如何使用软件包“IEC61850 WinCC Channel”配置WinCC为IEC61850客户端、“IEC61850 Test Harness”为服务器进行通讯连接、变量创建及报警管理的操作步骤，提供了一种基于SIMATIC WinCC的IEC61850规约的西门子通讯解决方案，希望能够给读者关于WinCC的IEC61850规约通讯入门指导。
IEC61850是新一代的变电站自动化系统的国际标准，它规范了数据的命名、数据定义、设备行为、设备的自描述特征和通用配置语言。同传统的IEC60870-5-103标准相比，它不仅仅是一个单纯的通信规约，而是数字化变电站自动化系统的标准，它指导了变电站自动化的设计、开发、工程、维护等各个领域。该标准通过对变电站自动化系统中的对象统一建模，采用面向对象技术和独立于网络结构的抽象通信服务接口，增强了设备之间的互操作性，可以在不同厂家的设备之间实现无缝连接。智能化一次设备和数字式变电站要求变电站自动化采用IEC61850标准。IEC61850是至今为止最为完善的变电站自动化标准，它不仅规范保护测控装置的模型和通信接口，而且还定义了数字式CT、PT、智能式开关等一次设备的模型和通信接口。采用IEC61850国际标准可以大大提高变电站自动化技术水平、提高变电站自动化安全稳定运行水平，节约开发验收维护的人力物力，实现完全的互操作。
IEC61850与传统的SCADA协议不同的是，它不仅是一个简单的协议，更涉及到通讯网络性能要求、对象建模、系统和项目管理等多方面的规菹要求IEC61850采用面向对象的建模方法和抽象、分层映射的技术，通过规范系统和项目管理以及一致性测试等途径来保证其目标的实现，并且IEC61850不仅适用于变电站自动化系统内部网络通信，也适用于配电自动化、电能计量系统、发电厂自动化系统、风力发电以及其它工业领域。

(LD), instruction list (IL), sequential function chart (SFC), structured text (ST) and other graphical configuration methods. The system contains about 220 functions
Algorithm library for energy blocks and a basic library with more than 200 graphic symbols and an extended library with a large number of 3D symbols.
