Organizations, Fairs, Events


  • UniversalAutomation.Org - “An independent, not-for-profit association of users and vendors managing the implementation of an industrial automation shared source runtime, based on the IEC 61499 standard. This new level of shared technology provides the basis for an ecosystem of portable, interoperable, “plug and produce” solutions and creates an entirely new category within industrial automation. UniversalAutomation.Org is open to new members willing to change the game of automation”.
  • Club of Metalworking - Free membership.
    • Free Admission. Club members receive free seasons tickets to the premier trade fair, the EMO Hannover as well as to the international trade fair, the METAV in Düsseldorf.
    • Free Public Transport. Get in and off you go: Only as a club member can you take a free ride by bus and train to the EMO Hannover and METAV on local public transportation.
    • Member Card. The exclusive club card is your ticket to the world of metalworking. Show that you are one of us, and enjoy the many benefits.

    2. DE.Wikipedia "WinCC" - “Die Varianten Basic, Comfort und Advanced dienen zur Projektierung von Bedienpanels wie der Vorgänger WinCC flexible (Nachfolger von ProTool), während die Variante Professional auch für die Projektierung von HMI-Systemen auf PC-Basis geeignet ist”.

Some other Companies in the Automation / PLC Industry

Automation & Drives



  • FANUC Deutschland GmbH - Market leader of CNC machnes. Experts told me that FANUC once defined the CNC standard ( the “G” and “M” commands ).
    • With special-purpose machines, there is often the system structure:
      • PLC.
      • Main controller. An embedded PC with a Linux based (Realtime) OS called “HeROS 5”.
        • Conversion of CNC code into PLC code.
        • Uploading of IEC61131 software code into the PLC. By that, the Linux PC controlls the machine by the help of the PLC.
        • Note: Experts told me that in the early 2000th, Heidenhein's controller was running Windows with a “realtime kernel”.
      • Windows based HMI, with CNC code generation and display.
    • Heidenheim's CNC language is named “Klartext”.

Impact of Hardware Resets

  • A hardware reset has negative effect on:
    1. Operation-hour counters in PLCs which just store data in PLC's RAM.
    2. If you configured your control parameters manually, for several hours ( without hand-written documentation of the data ).
