标准范围

IS0 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。IS0 10303本部分中的集成资源结构定义了用于指定的结构:过程之间的关系、过程的有效性、过程的属性、过程所需的资源、资源的属性、过程的表示、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的资源构造时，可以将集成的资源构造组装成一个结构来表示流程计划。以下内容属于IS0 10303本部分的范围:-工艺规范；-过程之间关系的规范；-过程有效性的说明；-过程和产品之间关系的说明；-产品实现过程计划的步骤说明；注1——IS0 10303的这一部分对已执行和未执行的工艺计划没有任何区别。2-IS0 10303的本部分不涉及流程计划中的管理信息。管理信息可能包括组织、日期或负责制定过程计划的人员。-替代工艺计划定义的规范；-工艺计划实现方法的说明；-资源的规格说明；-资源的过程要求；-识别过程使用的资源；-资源属性的说明。以下内容不在IS0 10303本部分的范围内:-特定过程或特定过程计划的定义；注3——IS0 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——IS0 10303的这一部分能够表示连续过程的某些方面。IS0 10303的这一部分无法表示需要中断、报警和其他消息服务要求的连续过程。-日程安排；-工艺规划；注5:工艺计划是制定工艺计划的行动。创建过程计划的操作不在IS0 10303本部分的范围内。IS0 10303的这一部分提供了过程规划输出的表示。-对等通信机制，包括同步；-过程控制。注6——过程控制和点对点通信的能力由其他IS0标准定义，如ISO/IEC 9506（工业自动化系统）-制造信息规范）。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IS0 10303的这一部分与ISO/IEC 9506之间的关系。

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.
