AVEVA connector group properties

MaximumTimeDomain

The maximum period that a request from the AVEVA™ Historian connector can cover.

Depending on the configuration, the connector can poll from the end of the sample stream or from the last sample. Regardless of which point the connector polls from, tags are polled every poll interval for a period that is no longer than the MaximumTimeDomain property until the connector is up-to-date.

If you specify a status tag, AVEVA™ Production Management ignores the maximum time domain setting of the group.

hh:mm:ss

Offset

The difference from the current time when making requests from a server.

hh:mm:ss

PollInterval

The frequency at which AVEVA Production Management polls the external system.

Set this property to a value greater than the scan rate, which is the time it takes for the data to make a round trip from request to reply.

The speed and activity of the network and system can restrict the poll interval. Alter the PollInterval setting with consideration of system performance maintenance.

<hh:mm:ss> Minimum is 1 second (00:00:01). Maximum is 23 hours, fifty-nine minutes, fifty-nine seconds (23:59:59).
