33、ystemsPart 1Process Control Systems Functions and Functional Specification Development1 Overview1.1 INTRODUCTIONAdvances in computing and digital communications technologies since the preparation of the 1st edition of API RP 554 have had major impacts on the way instrumentation and control systems f

34、unction as compared to historical designs. The advances have also radically changed the way that the design and specification of such systems must be approached and have created major issues relative to system design and system security. These issues are: The virtual disappearance of conventional ce

35、ntral control room control panels. Advances in computing power, software standards and communications standards have resulted in many of the functions historically implemented in stand alone process control and historization computers being integrated within the Process Control Systems. This has gre

36、atly expanded the scope of Process Control System design and blurred the division between real time control and historization functions and higher-level information systems that provide input to business and main-tenance systems. Advances in field instrumentation design leading to the general use of

37、 “smart” digital field instrumentation. Further advances in fieldbus and related technologies allow these “smart” instruments to communicate directly with the Process Control Systems or with each other. These instruments not only transfer information about the basic process measurement, but also com

38、municate diagnostic information about the health of the device or other secondary information derived from the primary measurements. Further developments in standardization of operating systems and software practices have enabled use of standard com-puter components and peripherals operating on stan

39、dard operating systems. This has resulted in a developing trend away from control systems applications being implemented on proprietary hardware and software systems, but rather being implemented on standard personal computer, workstation and network communication products running widely available o

40、perating systems. This standardization has reduced the cost and increased the flexibility of the systems. It has also resulted in greater exposure of the Process Control System to external interference and requires additional support to keep the operating systems current and secure. Security and vir

41、us-protection are major concerns of newer Process Control Systems and must be addressed at both the design and operational phases. The result of all these technical advances is that Process Control Systems are no longer entirely based upon proprietary closed hardware and software systems offered by

42、a single vendor. While these implementations are still available and form the prepon-derance of the existing installed base, there is a very strong trend away from closed systems provided by one vendor, to more open systems based upon industry standard hardware and software which have both proprieta

43、ry and open system components.These trends result in a far greater flexibility in selection of the control functions and the control hardware. These trends place greater responsibility upon the design engineer and user to understand the interaction between Process Control Systems and the business fu

44、nctions of an organization; select and specify the functions that are necessary for a given application; and implement those functions in a safe, reliable, cost effective and maintainable manner. Therefore, this edition of API RP 554 has been reorganized and split into three documents in order to be

45、tter define the processes required to properly scope, specify, select, install, commission, operate, and maintain Process Control Systems. This Recom-mended Practice is not intended to be used as a purchase specification, but recommendations are made for minimum requirements that can be used as a sp

46、ecification basis. 1.2 SCOPEThis Recommended Practice addresses the processes required to successfully implement Process Control Systems for refinery and petrochemical services. The major topics addressed are:2 API RECOMMENDED PRACTICE 554 The basic functions that a Process Control System may need t

47、o perform, and recommended methodologies for determining the functional and integration requirements for a particular application. Practices to select and design the installation for hardware and software required to meet the functional and integration requirements. Project organization, skills and

48、management required to execute a process control project and then to own and operate a Process Control System.Figure 1 shows the general overall scope of refinery control and automation functions and the portions of which this recom-mended practice addresses. The second edition of API RP 554 has bee

49、n prepared by a collaborative effort of the API Subcommittee on Instrumentation and Control Systems and the PIP (Process Industries Practices) Process Control Function Team. As such, the general scope of the material contained has been expanded to cover general industrial process control topics that are applicable to both refineries and petrochemical facilities. (PIP is a consortium of owner and engineering/construction contractor companies whose purpose is to produce a set of harmonized engineering standards in a variety of discipline areas, including process control.)
