Aveva InTouch: How to determine if primary or secondary data source is being used?
Ryan Griggs posted a topic in HMI & SCADA
Greetings! I have several Access Names defined, which have Primary and Secondary data sources configured, and Failover is enabled. We are using the built-in failover logic to determine when failover should occur (we are not manually forcing failover). I would like to show some sort of indicator to the user when the Secondary source is being used. I am aware of the $Sys$Status tag which is true if the data source is connected and false if it is disconnected. However, this tag doesn't tell us which source is being used (primary or secondary). Is there another $Sys tag or other tag that would tell us this info? Thank you for any pointers!
