High Availability Connection Preferences
The connection preference is set at the time of the first connection.
For FactoryTalk Historian DataLink 3.1.6 and above, the connection
preference for DataLink functions is set to Any. However, since the
connection preference is set at the time of the connection, the order in
which the connection is made matters. If the first connection is made with
DataLink functions, then it makes a connection with connection preference
of Any. If the first connection is made with the trend control, tag search, or
the connection manager, then the connection preference is set to Prefer
Primary.
See "Default Connection Preferences" in the FT Historian SE High
Availability Administrator Guide for an explanation of connectivity
preferences.

Firewall Database

configured to allow access from client computers running FactoryTalk
Historian DataLink. For example,

hostmask,value PIConfig> @select hostmask=* PIconfig> @ends
*.*.*.*, ALLOW
blocks no IP ranges, indicating that all client machines may connect to
FactoryTalk Historian 3 server. In contrast,
