本标准将定义电力变电站智能电子设备（IED）之间交换消息的标准通信测试场景。这些场景将定义变电站内应用程序之间以及变电站IED和远程定位应用程序之间的消息事务。这些场景不会指定实现事务所需的通信协议。

This standard will define standard communication test scenarios for messages to be exchanged between electrical power substation intelligent electronic devices (IEDS). The scenarios will define message transactions between applications within the substation and between substation IEDs and remotely located applications. The scenarios will not specify the communication protocol required to implement the transactions.
