Interface Startup Parameters

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.
