Parameter

Description

/updateinterval=#

Optional

Default = 120 seconds

This parameter can be used to adjust the interval with which
UniInt checks for point updates. The default interval is 120
seconds, the minimum interval for checking for point updates
is 1 second, and the maximum interval is 300 seconds. See
the section on Point Updates for more information.

This parameter can be set to 0. Setting the update interval to
0 will disable checking for point updates. Modifications to the
Historian point database will not be discovered by the
interface without stopping and then restarting the interface. If
the Historian point database is very stable, this disabling the
checking for point updates will slightly reduce the chances of
missing scans when communication between the Historian
Server and the interface is interrupted. An interface may miss
scans at this time because the API function to check for point
updates will not return until a response is received from the
Historian Server or a timeout is reached. UniInt will not be
scanning while it waits for the API call to return.
