The moment, the United States automation industry circles there is a saying the following: “In the process of industrial 4.0, the process industry has been in flight , and discrete manufacturing still check in . “reminiscent in the 2013 Hannover Fair report industry 4.0, it is difficult to find a description of the process industry in the future. Why? Discrete tricks, the process would have seen the industrial progress for 4.0 discrete manufacturing and process industries, the US theory of “fast and slow” of what? Since the establishment of the German industrial working group to 4.0 now has more than five years, the painstaking efforts of the German migration to the discrete manufacturing sector, is really still in the initial stage it? This requires a difference from the process and discrete manufacturing industries say open. And discrete manufacturing industries are significantly different, the nature of the production process is a continuous process industry , the working fluid being processed, whether the physical change or chemical change generated, the process never He interrupted, and often in a closed pipe or vessel (refining, petrochemical, chemical, etc.). Theory metallurgy process with further material flow, the continuity of the energy flow and information flow will be described. This requires the use of automated instrumentation, control systems, computer systems to detect status and parameters, control, forecasting, decision-making and implementation. Obviously CONTROL ENGINEERING China Copyright , from the history of technology and automation equipment point of view, the process of industrial automation, networking and intelligent demand and industry to achieve, has been at the forefront of discrete manufacturing of. Was introduced to the discrete manufacturing industry in contemporary popular 4.0 OPC UA technology and intelligent manufacturing for example, the first is used in process industries, and achieved remarkable results later. Evident. Connectivity and data collection industry 4.0 concerns technology, assets, process industry in twenty or thirty years ago has been in the use of the. But also a lack of height and time horizons of today’s industry 4.0. The current industrial process industries should be the focus of 4.0, the optimization process for the realization of the right time, minimize risk and maximize returns, through a variety of existing software systems technology and efficient integration of various data, the use of artificial intelligence deep learning, reinforcement learning (mainly dynamic programming method) for real-time data analysisAnd real-time decision making. Technology is only a means of empowerment, and how to go beyond the original concerns of business and the scope of the plant, extends to the supply chain and production services around the processes and structures of production organization, through its value chain, the use of sophisticated and innovative technologies (such as IIoT , cloud services, digital twin, etc.) to achieve quality and efficiency, reduce consumption and adapt quickly to changes in market demand, is the goal lies. In this process industries need to play a more human factors and factors of production processes, make up for the lack of industry 4.0 of concern. Automation systems integration architecture facing the international standard IEC / ISO 62264 born out of the ISA 95 overhaul of corporate control. Although this standard is developed on the basis of Purdue CIMS model, suitable for process industries, discrete manufacturing and batch process industries, but after all, the first to receive widespread support and practical application of process industry. “Hierarchy Levels” dimension of industrial RAMI4.0 reference architecture model 4.0 is mainly draws on the concept of ISA 95. Since the end-user acceptance and favor this ISA 95 reference model, development companies in the United States and the European software industry are generally based on this model. In order to better serve the needs of intelligent manufacturing IIoT and, as shown in Table 1. Copyright Control Engineering , ISA 95 increases the level L5 (corporate access above the original level L0 to L4 integrated cloud system).

ExxonMobil research and engineering departments open initiative to develop a new, standards-based process control architecture, has been for several years. In 2014 they produced a document the basic characteristics of the distribution on the ARC ARC Advisory Group forum held in 2015. Since then sparked three days of discussions, received considerable attention has also been supported by other end users have the same requirements. Group of the US Open (The Open Group) professional and successful performance in the creation of standards for other industrial sectors, Exxon Mobil decided to entrust a third party to this non-profit organization a new standardization activities Copyright Control Engineering All , process control challenges facing the industry, business and technology, the development of a new standard. Followed by The Open Group to create an open forum process automation OPAF (the Open Process Automation? Forum), absorbed a number of original members, and in November 2016 held its first meeting in San Francisco. Forum currently has more than 110 member organizations, including categories of end users, hardware and software vendors, system integrators, academic institutions and standardization organizations. Its representative members are: large end-user (such as Exxon Mobil, BASF, British Petroleum BP, DOW, etc.), automation of multinational corporations (such as Siemens, ABB, Schneider, Yokogawa, GE, etc.), IT big crocodile (IBM, ORACLE, etc.), communications equipment manufacturer (such as Huawei, Cisco, etc.), well-known consulting group (such as ARC, etc.), software giant industrial process industries (such as Aspentech, etc.), industrial standardization organizations (such as OPC Foundation , PLCopen, etc.), they together together a blueprint for a new generation of industrial process architecture. It is noteworthy that, DCS architecture has been no change in the 20 years, it is becoming increasingly obsolete, OPAF ongoing work will use the latest cloud computing technology to redefine the DCS and PLC. Also includes advanced control and optimization MES is closely related to operations (see Figure 1).

the old automated end? Senior consultant ARC of Harrry Frobes commented: “Since the automation hardware and software architecture in 1970 after entering the PLC and DCS automation, in ISA L1 95 and L2 of the control layer has been no change in the structure of the automation market has so far has been around bundled automation hardware and software in a structured way and this evolution in 1970 is very similar to a small computer market: at that time, virtually every minicomputer vendors are based on hardware and software bundled application methods and software tools, Community and its channel partners and software vendors to enter and dominate the market. open process automation Forum OPAF to large end-user-oriented form appears, process automation vendors and their supporters composition, has been integrated on the vertical height business models a threat, is likely to approach the end of its mission. “
FIG. 2:. OPAF architecture diagram
process industry given by the architecture of FIG clearly visible in FIG. 2, OPAF predeterminedThe distributed control DCN indicates the sense node, which is the DCF (Distributed Control frame) and DCP (distributed physical infrastructure) composed. The yellow components and modules are the subject of OPAF defined; other systems are the subject of non-sea-blue OPAF defined, such as traditional DCS, PLC, analysis instrumentation systems, electrical systems, mechanical systems …… monitoring, but they are It can be coupled to the framework via a DCN OCF OPAF defined. Even the process of enterprise business transaction platform (enterprise IT data centers) and other non-OPAF environmental systems, can access OCF via DCN. As ISA 95 performs L2 and L3 functions (e.g., advanced control algorithms, MES, etc.) of the data center OT OCF directly linked with this advanced computing platform container of the software technology, the functions of different tissue APP received in different container, a highly efficient execution of the software subsystem. These members work together to make the power and value of innovative software technology is not only widely used in the process industry, and makes its new business model, able to enter a number of other areas, including industrial and factory automation FA things IIoT. This subversion is driven software application called “containerized.” Software container technology originated decades ago UNIX operating system, it has been able to continue the rapid development today, thanks to vigorously promote the enormous quantity of Linux open source ecosystem as well as a large number of providers of cloud computing services. These huge forces first started positive impact continuous process automation time, meaning the process industry is flying at a faster speed. Conclusion American process industry is stalked its industrial 4.0. Obviously, this guide with the Government of the German Industry 4.0, route planning and the whole nation relying on industry-related organization and implementation of different, this is a result of unity of purpose, self-organized by the Community of the relevant industry, and make full use of commercial planned manner, there are steps to advance. Large enterprise process industry is behind the super promoter. It can be seen that the field of industrial automation technology of a huge whirlpool is approaching. This has the potential to subvert the will cause suppliers to maintain long-term business model has become obsolete, and had to be abandoned. It also requires suppliers to use software technologies and practices from the field of cloud computing is emerging. Obviously, this will be almost the entire subversion of the new software technology, rather than hardwareThe drive technology. Software, in particular cloud computing technology-driven distributed software, automation technology will allow to open a new journey.
