Christian Diedrich and Georg Bretthauer at Otto von Guericke University Magdeburg (from right, 2008)

Christian Diedrich (born April 2, 1957 in Babelsberg near Potsdam ) is a German engineer and professor for "Integrated Automation" at the Otto von Guericke University in Magdeburg . He is the deputy chairman of the board and the head of the non-university research facility “Institute for Automation and Communication” (ifak) in Magdeburg.

After graduating from high school , which he graduated with distinction in 1975, Christian Diedrich graduated from 1976 to 1985 with a degree in electrical engineering, specializing in "technical cybernetics and automation technology", at the technical university "Otto von Guericke" Magdeburg (THM), section Technical cybernetics and electrical engineering (TK / ET). He chose the specialization in automation technology , which has existed at the THM since 1960, originally as control technology (founder: Heinrich Wilhelmi ). He was particularly interested in the computer-aided modeling of technical processes, which he carried out using the example of diesel engines under the supervision of Professor Siegfried Rudert . During the course there was an interruption from January 1981 to August 1983; During this time Diedrich worked as a fitter in the heavy machinery construction combine "Karl Liebknecht" (SKL) in Magdeburg.

His studies in the field of "Control Engineering and Process Control" coincided with major personnel changes due to the departure of four university lecturers: Herbert Ehrlich (1975 to Leipzig), Heinz Töpfer (1978 to Dresden), Werner Kriesel (1979 to Leipzig), Siegfried Rudert (1980 deceased). The following were appointed as new professors: 1978 Ulrich Korn to the chair “Control engineering ” and 1981 Peter Neumann to the chair “Devices and systems of automation technology”. In 1978, the management of the science department changed from Heinz Töpfer to Siegfried Rudert . Between 1980 and 1985 Ulrich Korn succeeded Siegfried Rudert, who died unexpectedly, as head of the science department; then Peter Neumann took over this function.

In 1985 Diedrich finished his studies as a graduate engineer (Dipl.-Ing.) At the THM with the rating "Very Good" under the rectorate of Reinhard Probst in the section technical cybernetics and electrical engineering with the section director Reinhold Krampitz . In his diploma thesis he dealt with a programmable logic controller (PLC) that was newly available at the time for coordinating a lathe with a robot.

This was followed by 5 years of industrial activity, which initially led Diedrich to work from 1985 to 1988 as a software developer for test technology in the device and controller factory (GRW) in Leipzig . This plant had developed from the device and controller works in Teltow, the "central plant construction of BMSR technology", so that device and plant construction was also a profile-determining factor in Leipzig. Here he acquired detailed knowledge of microcomputing technology and the associated programming. He then worked from 1988 to 1990 as a research assistant at the Scientific and Technical Center for Dry Fodder Production in Gatersleben . Here he worked on the planning and implementation of electronic and automation equipment and got to know project planning and the practical handling of measurement, actuation and control technology. He was also involved in the planning and implementation of a Unix computer network for the business evaluation of process data.

In the course of German reunification , the control engineering and process control research area was transferred to the "Institute for Automation Technology" (IFAT) with the participation of Peter Neumann and Ulrich Korn and expanded to around 30 employees with 4 chairs. In this context, Diedrich returned to the Otto von Guericke University Magdeburg and worked there from 1990 to 1992 at the Institute for Automation Technology, which was headed by Peter Neumann at the time , as an aspirant and research assistant in third-party funded projects. During his traineeship, he dealt with the then newly emerging topic of field buses as special communication systems for distributed automation systems. As part of the BMBF PROFIBUS project , he was responsible for creating profiles and headed a working group that worked out a corresponding guideline for PROFIBUS, on which other fieldbuses such as Interbus , LON and CANopen were based. In this area, Diedrich is one of the leading experts, which is also expressed in the transfer of managerial responsibility in research projects (Esprit Project NOAH) as well as in the management or collaboration as an editor in standardization projects (IS IEC 61804 and TR IEC 62396).

In 1991 Neumann founded a registered association for the promotion of automation and then the "Institute for Automation and Communication eV (ifak)". From November 1992, Diedrich moved to ifak, initially as a group leader, later as division manager for automation systems and as deputy institute director.

In 1994 he received his doctorate with a dissertation prepared under the supervision of Peter Neumann on "Interface layers and profiles for field bus systems and their formal specification"; Award of the academic degree of Doctoral Engineer (Dr.-Ing.) With the overall rating "cum laude" by the Faculty of Electrical Engineering (Dean: Ulrich Korn ) of the Otto von Guericke University Magdeburg.

Ifak ​​building in the Magdeburg Science Harbor

For Diedrich, the period from 1992 to 2006 was characterized by his scientific work and his managerial functions at the non-university research institute ifak eV, Magdeburg:

  • Conception, development and management of the "Automation Systems" area with the "Engineering Methods" and "Applications" groups,
  • Activity as a representative of the ifak institute in various specialist committees and organizations: In national and international standardization and specialist committees such as B. IEC, DKE, Industry 4.0 platform, ZVEI, PROFIBUS user organization (PNO), Diedrich is involved in the creation of the relevant standards.

From September 2000, Diedrich was appointed honorary professor for the field of "Integrated Automation" by the Faculty of Electrical Engineering and Information Technology at the Otto von Guericke University Magdeburg at the "Institute for Automation Technology (IFAT)".

At the beginning of 2005, Ulrich Jumar was elected chairman of the board and director of the ifak institute and succeeded Peter Neumann in these functions. Diedrich became Jumar's deputy in both functions. In April 2006 Diedrich was appointed full professor to the chair of "Integrated Automation" at Otto von Guericke University. Since 2006 he has taken over the management of the "Institute for Automation Technology" (IFAT, today abbreviated ifat). He continues to exercise his two representative functions at ifak, so that there is also close interaction between ifat and ifak.

Diedrich's main areas of work include: industrial communication, integration and description methods for automation devices and systems (function block technology, fieldbus profiles, device and product descriptions such as EDD, FDT, FDI, IEC 61131), engineering methods and information management (object-oriented analysis and design, UML , Web technologies, knowledge processing), formal and semi-formal methods in automation technology.

Diedrich has published over 100 publications in the field of automation technology and through co-authorship in specialist books. For many years he has been involved in the scientific management of conference series and congresses.

In addition to Christian Diedrich, other professors have their roots at ifak: Rudolf Mecke ( Harz University , Wernigerode), Anatoli Makarov ( Magdeburg-Stendal University ), Stephan Kühne ( Zittau / Görlitz University ), René Simon (Harz University, Wernigerode), Jörg Auge (Magdeburg-Stendal University), Martin Wollschlaeger ( Dresden University of Technology ), Bernd Henning ( Paderborn University ), Robert Hoyer ( Kassel University ), Jürgen Jasperneite ( OWL University , Lemgo) and Ulrich Jumar ( Otto von Guericke University Magdeburg ) .

Teaching

Diedrich's teaching activities at Otto von Guericke University Magdeburg include:

  • Process control technology
  • Communication systems
  • Technical languages ​​and software technology
  • Controls on higher management levels.

In 2003 and 2004, Diedrich held lectures on process automation at the Clausthal University of Technology , Institute for Electrical Information Technology. These were prepared jointly with Renè Simon (then: ifak Magdeburg, today: Professor of the Harz University of Applied Sciences in Wernigerode) and in some cases also held jointly.
