Pre-Installation Tasks
Before you install FactoryTalk Historian SE, do the following:
• Synchronize time settings on Historian system computers
(page 17).
• Disable the Windows time zone (page 17).
• Learn about installation-related recommendations (page 18).
• Configure IIS for Advanced Server components (page 18).
For all machines that are part of the FactoryTalk Historian system,
you must ensure that the time is set correctly and synchronized with
the FactoryTalk Historian server. In addition, make sure that all
Windows machines have the proper time-zone settings and that they
are set to automatically adjust for daylight-saving changes.
The clocks of the FactoryTalk Historian server computer and client
computers should all be synchronized. This is typically done through
the domain controller. The domain controller's time is synchronized
first by an NTP source. Then, the domain controller synchronizes
all other computers that are a part of the FactoryTalk Historian
system.
For details, search the Rockwell Automation Technical Support
(http://rockwellautomation.custhelp.com/) web site for daylight
saving time.
The Windows time zone (TZ) environment variable adversely
affects the Historian server. You must ensure that TZ is not set on
the Historian server computer.
