Tracking interface status

To track interface status, create the following digital PI points on the target Data Archive:

• Internal state PI point

  Indicates whether the interface is in startup, performing history recovery, scanning for data, experiencing network communication errors, denied data or point access (security permissions) or performing shutdown operations. To enable this point using PI ICU, go to the PItoPI>Debug tab, check Interface Status Tag on Receiving PI Server, and specify the name of the PI point.

• Failover status PI point

  If you enable source Data Archive-level failover, you can configure a PI point that tracks failover status. To configure the point using PI ICU, go to the PItoPI>Source PI Server Failover tab, check Enable failover status logging, and specify the name of the PI point.
