标准摘要
[中文适用范围]： 本技术报告提供了关于 IEC 61158、IEC 61784-1、IEC 61784-2 和 IEC 61800-7 的概述和指南，涉及控制单元与其相关设备之间用于传输周期性和非周期性数据的实时串行接口。该接口旨在应用于工业机器，例如通过该接口连接多个设备机床。该接口支持不同的操作模式。 [外文原描述]： IEC/TR 61491:2010 presents an overview and guidance for IEC 61158, IEC 61784-1, IEC 61784-2 and IEC 61800-7 with respect to a real-time serial interface between the control unit and its associated devices, which is utilized to transmit periodic and non periodic data. This interface is intended to apply to industrial machines, such as machine tools, with multiple devices connected via this interface. This interface supports different operation modes. This first edition of the technical report cancels and replaces the second edition of IEC 61491, published in 2002. The changes are primarily to make reference to material that was moved to IEC 61158, IEC 61784 and IEC 61800-7 series of standards.
