3.1 Overview of recommended configurations
Introduction
Various techniques are possible for time synchronization. The structure of a PCS 7 plant with
time synchronization requires careful planning in order to prevent any undesired results. Use
one of the following configurations to support you in planning your PCS 7 plant.

Configurations in Windows domains
Note
This document subdivides the recommended configurations for time synchronization in a
Windows domain (recommendations 3 and 4) on the basis of hierarchy levels. The sections
that follow shows the structure in configurations with different hierarchy levels:
• "Configuration of time synchronization with a central time master in a Windows domain
with one hierarchy level"
• "
Configuration of time synchronization without a central time master in a Windows domain
with multiple hierarchies (Page
