Process Automation 25-9 challenging as process plants incorporate a large investment. Therefore, new means are necessary that allow utilizing production facilities for different products and allow fast switches between products to be produced. For such systems, [GNP94] coined the term “agile manufacturing.” In order to provide such manufacturing systems, the dynamic reconfiguration of plant structures as well as the control software is required. Parametric changes are not enough as they lead to unmanageable control software modules. Fifteen years later, recently conducted surveys such as the MANUfuture Strategic Research Agenda [EC06], which is one of the platforms that are integrated in the definition of the frame programs of the European Union, claim the same objectives. Multipurpose facilities built in the above described network plant structure provide the demanded flexibility and adaptability from the mechanical/physical point of view [K99]. In order to operate such plants effectively and efficiently, new ways for the control structure have to be used. Distributed control with its control nodes locally attached to the plant controlled part represents such a means. Distributed control architectures allow localizing changes and disturbances in the plant. This helps to keep changes manageable for the human as not the whole system has to be investigated. Furthermore, distributed control systems feature an increased scalability allowing to add or remove plant parts. First works on this topic were able to show these benefits, e.g., [LZ08,PCSK07,SSPK06, and TSPK07]. Distributed control systems are an important foundation for flexibility and reconfigurability of production systems. However, in case of changes, disturbances, plant failures, or adaptations, labor-intensive engineering work is necessary. Therefore, more autonomous technologies are needed in order to reduce the human effort incorporated in production changes, as the human effort needs time (i.e., costs) and is typically error prone. A possible approach is to enhance the distributed control modules with autonomous cooperative functionalities. These allow the unit to provide its functionality (e.g., process reactor) to the production system and cooperate with other units like pipes, valves, pumps, or other process reactors in order to fulfill the overall goal production. For assembly automation, several such approaches were investigated and tested (see for example [B06,LR06, or VMM08]). They were able to show that the flexibility and adaptability of the plant is increased. More research is nevertheless still needed in this area before these concepts can be applied in industrial systems, especially for process automation where only little research has been done. These new paradigms do not change the general production information exchange as described above; however, they change the overall structuring of the control system’s architecture and therefore also the ways control components interact. The hierarchical structuring as shown in Figure 25.1 will be broken up into a network oriented one. Therefore, the control architecture resembles the mechanical structure of a flexible (batch) process plant. This leads away from the currently employed request/reply (e.g., client/server) interaction to a peer-to-peer interaction. Future control components will be equal members of the production system and interact with each other on a negotiation basis. However, as process automation systems interact with the real world, there are different kinds of interaction on different levels with different properties. On the higher levels, there are the negotiations between control components in order to fulfill the overall task production. These negotiations feature a higher amount of data but are in general less time critical. On the contrary, on the lower interaction levels—the real-time control levels—the communication’s task is to synchronize the control algorithms. For this purpose, we encounter short messages that have to be transmitted and processed in real time (see Figure 25.4). Communication systems for upcoming process automation systems, therefore, have to support the peerto-peer communication of equal distributed control components. This communication has to be flexible, allowing changeable communication relations and also support real-time interaction as needed by the real-time control elements. Current communication systems for process automation are developed for the hierarchical command/response or master/slave paradigm as applied in today’s process automation systems. These systems are not suitable for the upcoming needs of distributed control and autonomous production resources. Therefore, new communication systems have to be developed in order to support the new paradigms. © 2011 by Taylor and Francis Group, LLC

This trend began with connecting control devices with high-level systems like ERP and SCADA systems, which was followed by replacing controller networks providing less time critical controller-to-controller communication. Currently, Ethernet moves also into the fieldbus world. The advantage of uniform data access and exchange on all levels of a production system and between all components is one of the reasons for this trend. Especially, ERP systems and production planning and scheduling system are systems for which it is believed that they can benefit most of this uniform data access. This should enable such systems to get a more complete view of a plant’s state and therefore allow a better planning and scheduling of the production. However, Ethernet by itself is not capable of fulfilling the needs of typical fieldbus systems. Therefore, different enhancements and changes to Ethernet were developed. Examples for such Ethernet-based fieldbus technologies described in this book are as follows: EtherCAT, Powerlink, Profinet, and ModbusTCP. The main problem of many of these systems is that they apply major changes to the protocols and system behavior of what is commonly known as Ethernet. In the end, many of the described systems have just the wiring of Ethernet (e.g., Profinet IRT). Furthermore, as all of the industrial Ethernet protocols use different methods, they cannot be used in parallel on the same wire or operate together. Therefore, we are again in the same situation the fieldbus diversity has brought us. So, finally the great expectations especially from the higher production system level could not be met. The current state of industrial Ethernet is as such that we have a new bunch of high bandwidth fieldbuses. © 2011 by Taylor and Francis Group, LLC
