IEC 61175-1:2015规定了用于识别信号和信号连接的名称组合规则。这包括电源的指定。IEC 61175的本部分适用于工业系统、装置和设备以及工业产品中的所有类型的信号。它涉及信号的信息方面，而不是信号的物理实现。本第一版取消并取代了2005年发布的IEC 61175第二版，构成技术修订版。它包括以下变化:对使用原则的改进描述，以及信号的物理方面与其相关信息之间的严格分离，重点是后者。本水平标准主要供技术委员会根据IEC指南108中规定的原则编制标准时使用。

IEC 61175-1:2015 provides rules for the composition of designations for the identification of signals and signal connections. This includes the designation of power supply. This part of IEC 61175 is applicable to all types of signals within an industrial system, installation and equipment and industrial products. It deals with the information aspect of signals and not with their physical implementation. This first edition cancels and replaces the second edition of IEC 61175 published in 2005 and constitutes a technical revision. It includes the following changes: an improved description of the principles for use and a strict separation between the physical aspect of a signal and its associated information, focusing on the latter. This horizontal standard is primarily intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 108.
