工业自动化系统和集成 产品数据表示和交换 第49部分:集成通用资源:工艺结构和特性

[中文适用范围]： ISO 10303 的这一部分指定了资源构造，以指定影响流程的操作或潜在操作。 ISO 10303 这一部分中的集成资源构造定义了用于指定的结构：流程之间的关系、流程的有效性、流程的属性、流程所需的资源、资源的属性、流程的表示、资源的表示以及过程与产品的关系。 当在应用程序资源或应用程序协议的上下文中使用这些集成资源构造时，可以将集成资源构造组装成表示过程计划的结构。 以下内容属于 ISO 10303 本部分的范围： ——过程规范； ——流程之间关系的规范； ——过程有效性的规范； ——过程和产品之间关系的规范； ——实现产品的工艺计划步骤的规范；注 1 - ISO 10303 的这一部分对已执行的工艺计划和未执行的工艺计划没有任何区别。 2 - ISO 10303 的这一部分不涉及流程计划中的管理信息。 管理信息可能包括负责制定流程计划的组织、日期或人员。 ——替代工艺计划定义的规范； ——实现工艺计划的方法的规范； ——资源的规范； ——资源的过程要求； ——进程使用的资源的标识； ——资源属性的规范。 以下内容超出了 ISO 10303 本部分的范围： ——特定过程或特定过程计划的定义；注 3 - ISO 10303 的这一部分不涉及任何特定的工业过程。 ——连续过程的工艺规范；注 4 – ISO 10303 的这一部分能够代表连续过程的某些方面。 ISO 10303 的这一部分无法表示需要中断、警报和其他消息传递服务要求的连续过程。 ——日程安排； ——工艺规划；注 5 – 工艺规划是制定工艺计划的行动。 创建流程计划的操作超出了 ISO 10303 本部分的范围。 ISO 10303 本部分提供了流程计划输出的表示。 ——点对点通信机制，包括同步； -过程控制。 注 6 – 过程控制和点对点通信的功能由其他 ISO 标准定义，例如 ISO/IEC 9506（工业自动化系统 - 制造消息规范）。 这些其他 ISO/IEC 标准涉及过程工业中使用的工业过程控制系统的可编程设备的通信和互通。 应用程序资源或应用程序协议可以指定 ISO 10303 的这一部分和 ISO/IEC 9506 之间的关系。 [外文原描述]： This part of IS0 10303 specifies the resource constructs to specify the actions or potential actions to effect a process. The integrated resource constructs within this part of IS0 10303 define the structure for specifling: relationships between processes, the effectivity of a process, the properties of a process, the resources required for the process, the properties of the resource, the representation of the process, the representation of the resource, and the relationship of the process to the product. When these integrated resource constructs are utilized in the context of an application resource or an application protocol, the integrated resource constructs can be assembled into a structure to represent a process plan. The following are within the scope of this part of IS0 10303: - specification of a process; - specification of the relationships between processes; - specification of the effectivity of a process; - specification of the relationship between a process and a product; - specification of the steps for a process plan to realize a product; NOTES 1 - This part of IS0 10303 does not make any distinction between a process plan that has been executed and one that has not been executed. 2 - This part of IS0 10303 does not address administrative information within a process plan. Administrative information may include organization, date, or person responsible for developing a process plan. - specification of alternative process plan definitions; - specification of the method for realizing a process plan; - specification of a resource; - process requirements of the resource; - identification of resources used by a process; - specification of the properties of a resource. The following are outside the scope of this part of IS0 10303: - definition of specific processes or specific process plans; NOTE 3 - This part of IS0 10303 does not address any specific industrial process. - process specifications for continuous processes; NOTE 4 - This part of IS0 10303 has the capability to represent some aspects of continuous processes. This part of IS0 10303 does not have the capability to represent continuous processes that require interrupts, alarms, and other messaging service requirements. - scheduling; - process planning; NOTE 5 - Process planning is the action of developing a process plan. The action of creating a process plan is outside the scope of this part of IS0 10303. This part of IS0 10303 provides a representation for the output of process planning. - peer-to-peer communication mechanisms, including synchronization; - process control. NOTE 6 - Capabilities for process control and peer-to-peer communication are defined by other IS0 standards such as ISO/IEC 9506 (Industrial Automation Systems - Manufacturing Message Specification). These other ISO/IEC standards are concerned with the communication and interworking of programmable devices of industrial process control systems utilized in the process industries. An application resource or an application protocol may specify a relationship between this part of IS0 10303 and ISO/IEC 9506.
