How do you configure time synchronization using the NTP procedure (without SICLOCK) for small PCS 7 plants?
The Network Time Protocol (NTP) is a standardized procedure for synchronizing clocks in a computer network. It is based on the connectionless User Datagram Protocol (UDP).
NTP enables reliable transfer of time in computer networks of different topologies with different package runtimes.
The figure below shows a typical configuration of a small PCS 7 plant.
In this case, Stratum 0 is the RTC (Real Time Clock) in the BIOS of the OS server. Other sources can also be used (NTP server, for example) instead of the RTC of the server.

The documentation is designed to help you configure PCS 7 plants in which time synchronization is to be implemented using the NTP procedure.
