20、015(E)IntroductionAs a crucial part of manufacturing systems with increased complexity, the automation and control applications enabled by advanced process control and optimization (APC-O) methodology and solutions perform the operations directed by production planning and scheduling. ISO 15746 deal

21、s with the integration of APC-O with manufacturing operations management (MOM) and with automation and control of manufacturing process and equipment.The following IEC 62264 functionalities related to manufacturing are hierarchically structured in a functional model, as shown in Figure 1.a) Level 0

22、defines the actual physical processes.b) Level 1 defines the activities involved in sensing and manipulating the physical processes. Level 1 typically operates on time frames of seconds and faster.c) Level 2 defines the activities of monitoring and controlling the physical processes. Level 2 typical

23、ly operates on time frames of hours, minutes, seconds and sub-seconds.d) Level 3 defines the activities of the work flow to produce the desired end products. It includes the activities of maintaining records and coordinating the processes. Level 3 typically operates on time frames of days, shifts, h

24、ours, minutes and seconds.e) Level 4 defines the business-related activities needed to manage a manufacturing organization. Manufacturing-related activities include establishing the basic plant schedule (such as material use, delivery and shipping), determining inventory levels and making sure that

25、materials are delivered on time to the right place for production. Level 3 information is critical to Level 4 activities. Level 4 typically operates on time frames of months, weeks and days.Figure 1 Functional hierarchyISO 15746 mainly focuses on the integration of APC-O capabilities into control ac

26、tivities (Level 2) and MOM (Level 3), in Figure 1. ISO 2015 All rights reserved vBS ISO 15746-1:2015ISO 15746-1:2015(E)The APC-O system within Level 2 interacts with the MOM system of Level 3. It shall provide the information of the production processes to the MOM system, and in return accepts and e

27、xecutes the corresponding operational commands from the MOM system. The APC-O system within Level 3 samples measurement signals and monitors behaviour, and in return controls the operational systems within Level 2.Automation solutions composed of software and hardware are provided by different suppl

28、iers to accomplish APC-O capabilities. Due to the diversity of development environments and the variety of demand focus, the automation solutions from various suppliers are isolated and relatively independent. These differences make the integration of automation solutions difficult. Consequently, th

29、e customers may purchase different automation solution components with redundant and duplicated functions, resulting in a waste of resources and limited interoperability. This part of ISO 15746 offers a reference interoperability framework for APC-O. It is intended to maximize the integration and in

30、teroperability of automation solutions.This part of ISO 15746 is intended to help: identify an approach to assist the providers and system integrators of APC-O systems and related automation solutions components in verifying the interoperability of the components used to construct the automation sol

32、nts; outline the concepts and conceptual framework elements that will be sufficient to address the identified problems and opportunities; reduce the time and cost in defining and describing the application requirements, as well as, in developing and implementing automation solutions based on APC-O s

33、ystems.The target users of this part of ISO 15746 include users and providers of the APC-O solutions, such as project solution suppliers, automation systems integrators, production departments of companies, process engineers, independent software testing organizations, implementation and consulting

34、service organizations of APC-O software, and relevant governments and academic organizations.vi ISO 2015 All rights reservedBS ISO 15746-1:2015Automation systems and integration Integration of advanced process control and optimization capabilities for manufacturing systems Part 1: Framework and func
