本文件涉及安全接口和控制接口。它将信号分配给一致性类和/或一致性选项。它描述了每个信号的详细功能，在流程图中描述和显示了信号之间的时序交互，并显示了安全矩阵和安全相关功能关系的示例。 本文件定义了三个一致性类别和专用一致性选项。类别和选项由多个信号组成，用于: -允许根据项目灵活调整接口- 具体的职能范围，同时:将信号组绑得足够紧，以避免机器维护系统和机器供应商之间不必要的协调工作。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This document deals with the safety interface and control interface. It allocates signals to a conformance class and/or conformance option. It describes the detailed functions of each signal, describes and displays the timing interactions between signals in flow charts and shows examples for safety matrices and safety-related functional relationships. This document defines three conformance classes and dedicated conformance options. Classes and options consist of a number of signals to: — allow a flexible adaptation of the interface(s) to a project-specific scope of functions and simultaneously;— tie sets of signals tight enough to avoid unnecessary coordination efforts between suppliers of the machine tending systems and machines.All current amendments available at time of purchase are included with the purchase of this document.
