This paper presents an approach for using process knowledge in addition to structural knowledge for plant-wide diagnosis. System diagnosis based on faultdetection and fault-diagnosis often uses structural knowledge (e.g. hierarchies of sub-systems and components) to identify the root cause of faults and malfunctions. The structural knowledge describes the internal relationships of a plant and is particularly suitable for diagnosis if an assembly or component breaks down, which affects other parts of the system. However, the root cause of faults cannot always be identified based on structural knowledge alone, but information about the processes (e.g. production processes) is required in addition. Based on an integration of the VDI/VDE-guideline 3682 "Formalized process description" the authors present a method to consider process knowledge for an improved system diagnosis.

“…The first part of this standard defines the graphical representation of control relevant information at the P&ID. The second part defines the data format and the information flow between engineering tools (see [29], [30] and [31]). Until 2008, the present pre-standard is expected to become a final IEC (see [32] and [33]).…”

This contribution presents the usage of an abstract data exchange format for an automatic configuration of a production monitoring and control system. The automatic configuration procedure re-uses already existing engineering information stored in a standardized and system-independent data format like CAEX. Standard data formats enable - beside the possibility of reaching a transparent engineering value creation chain - the data access of computational algorithms which automatically analyze those data and automatically create engineering results out of them. Standard data formats are a key for the idea of "automation of automation". The concept is exemplarily implemented and explained by means of the configuration of ProVis.Agent® and ProVis.Visu® using CAEX

“…However it is only about data exchange, based on XML and provides a common exchange format between process control tools. A tools called CAEX Analyser, based on CAEX description, is capable of capturing process topology and linking plant information and results with data-driven analysis [21].…”

-This paper presents an overview of the works on design and validation of distributed control in process industry. Due to the significant market demand for distributed reconfigurable systems, not just in manufacturing industry but also in process industry, several researches are undertaken to look at the design techniques in implementation of such a decentralized control approach. It has shown that a distributed control can bring benefits such as flexibility, reconfigurability and software reusability. International standards such as IEC61499 and IEC61804 are established for such distributed application with newly introduced Function Block (FB) concepts. Intelligent control and multi-agents approach are emerging techniques for distributed control application. In particular, a process control system is generally considered as a hybrid system because it usually contains both discrete and continuous dynamics. Therefore when handling validation of distributed systems, hybrid verification and simulation will have an important role.
