IEC 61400-25-4:20 16 RLV包含国际标准及其红线版本。红线版本只有英文版本。Redline版本为您提供了一种快速简单的方法来比较该标准与其前一版本之间的所有变化。红线版本不是IEC官方标准，只有标准的当前版本才被视为官方文件。 IEC 61400-25-4:20 16规定了对协议栈的特定映射，该协议栈对客户端和远程服务器之间的信息交换所需的消息进行编码，用于:数据访问和检索、设备控制、事件报告和日志记录、发布者/订阅者、设备的自描述（设备数据字典）、数据类型和数据类型的发现。IEC 61400本部分规定的映射-25包括: -到基于SOAP的web服务的映射， -到OPC/XML-DA的映射， -到IEC 61850-8-1 MMS的映射， -到IEC 60870-5-104的映射， -到DNP3的映射。 与上一版相比，主要技术变化如下: -与IEC 61400-25-2中的信息模型和IEC 61400-25-3中的信息交换服务进行总体协调； -通过增加参考减少标准之间的重叠和简化。

IEC 61400-25-4:2016 RLV contains the International Standard and its Redline version. The Redline version is available in English only. The Redline version provides you with a quick and easy way to compare all the changes between this standard and its previous edition. The Redline version is not an official IEC Standard, only the current version of the standard is to be considered the official document.

IEC 61400-25-4:2016 specifies the specific mappings to protocol stacks encoding the messages required for the information exchange between a client and a remote server for: data access and retrieval, device control, event reporting and logging, publisher/subscriber, self-description of devices (device data dictionary), data typing and discovery of data types. The mappings specified in this part of IEC 61400-25 comprise:
- a mapping to SOAP-based web services,
- a mapping to OPC/XML-DA,
- a mapping to IEC 61850-8-1 MMS,
- a mapping to IEC 60870-5-104,
- a mapping to DNP3.
The main technical changes with regard to the previous edition are as follows:
- general harmonization with information models in IEC 61400-25-2 and information exchange services in IEC 61400-25-3;
- reduction of overlap between standards and simplification by increased referencing.
