自动化系统和集成.自动机器维护接口.第1部分:概述和基本原则

[中文适用范围]： 使用机器管理装置控制（CNC）机器。 这些接口是自动化机器维护设备和用于生产的机器之间的链接。 自动化机器维护由机器维护系统或机器启动。 本文档概述并定义了如何设置接口的基本原则。 它定义了必要的词汇并设置了信号结构的语法。 它区分安全接口、控制接口和项目特定扩展。 本文档定义了三个一致性类别和专用一致性选项。 类和选项由许多信号组成，同时： ——允许接口灵活适应项目特定的功能范围； ——信号组的联系足够紧密，以避免机器维护设备和机器的供应商之间不必要的协调工作。 机械连接，它不确定传输物理、引脚分配、接口硬件或通信措施（例如协议），并且不打算用于与 MES（制造执行系统）的通信。 注：ISO 21919-2 涉及安全接口和控制接口，将信号分配给一致性等级和/或一致性选项，描述每个信号的详细功能，在流程图中描述和显示信号之间的时序交互，并显示安全示例矩阵和安全相关的函数关系。 [外文原描述]： ISO 21919 describes interfaces for automated machine tending of at least one computer numerically controlled (CNC) machine by using a machine tending device. These interfaces are the link between automated machine tending devices and machines used for production. The automated machine tending is initiated by either the machine tending system or by the machine. This document gives an overview and defines the fundamental principles on how the interfaces are set up. It defines the necessary vocabulary and sets the syntax for the structure of signals. It distinguishes between the safety interface, the control interface and project specific extensions. This document defines three conformance classes and dedicated conformance options. Classes and options consist of a number of signals to simultaneously: — allow a flexible adaptation of the interface(s) to a project-specific scope of functions; — tie sets of signals tight enough to avoid unnecessary coordination efforts between suppliers of the machine tending devices and machines. ISO 21919 concentrates on the control-related and safety-related connections. It does not describe the mechanical connections, it does not determine the transfer physics, a pin assignment, the hardware of the interfaces or measure of communication, e.g. protocol, and it is not intended to be used for communication to a MES (Manufacturing Execution System). NOTE ISO 21919‑2 deals with the safety interface and control interface, allocating signals to a conformance class and/or conformance option, describing the detailed functions of each signal, describing and displaying the timing interactions between signals in flow charts and showing examples for safety matrices and safety-related functional relationships.
