    Fundamentals Using time synchronization in PCS 7 Introduction Plants in which Process Control Systems are used contain numerous components that exchange data. Most plants require time synchronization for controlling processes and information. There are additional requirements in terms of the documentation of event sequences.
  • Page 12 Fundamentals 2.1 Using time synchronization in PCS 7 Time synchronization Time synchronization means that one system component (time master) provides a precise time for all the other components (time slaves). The time information (date and time) can either be distributed by the time master, or be requested by the time slaves. For the overall task, all components within the system must evaluate this time information.

    Glossary CEDST Central European Daylight Saving Time Central plant clock An central plant clock receives a time signal from an external clock and transfers it to the terminal bus or the plant bus. Central European Time Clock, external External clocks synchronize a plant with the aid of externally received time signals, e.g. the radio signal DCF77 or the satellite based GPS signal.
