5.2.2 How to convert the local time zone and daylight saving time parameters
Introduction
You can convert the time displayed on the OS in process mode.
Rules
● If operating a plant across several time zones with different daylight saving time and
standard time settings, you should also use the harmonized UTC time for the time display
on the operator station. You therefore have a uniform basis for process analysis at all
plant units.
● You can configure the switch to daylight saving time or point in time for the switch for
each specific country. PCS 7 always handles internal functions on the basis of UTC.
Therefore, any conversion to daylight saving time or to a different local time does not
have any impact on the internal functions of PCS 7.
If the time display of the operator station is set to the local time of specific countries, with
automatic conversion of daylight saving time and standard time, the time is automatically
converted at the correct date and time.
Requirements
● It must be possible to operate the operating system environment.
● You must make the settings directly on the OS.
Procedure
To change the operator station to display daylight saving time and standard time, follow
these steps:
1. Go to the Window Start menu on the OS and select Start > Settings > Control panel.
2. Double-click the "Date and Time" icon.
3. Select the "Time Zone" tab.
Ensure that the time zone displayed in your list field is appropriate for your area
