Monitoring and notifying of "bad status" tag values in TopView

Monitored data points can report with a "Bad Status", which is an indication that the value of a tag in TopView may be questionable, or the server is experiencing issues.
You can detect bad statuses in TopView and notify people when they are present.

Detecting bad statuses in TopView

  1. Detect bad statuses in aggregate. This is useful for cases where an OPC connection is occasionally unreliable:
    1. Monitor "bad status" in the aggregate by adding the TopView Status Tag "statusnotgood_count" to your configuration, which returns the number of tags with bad status values in the current configuration.
    2. Configure an alarm condition for statusnotgood_count when this value is greater than zero; configure notifications for this alarm.
    3. This setup allows you to monitor bad status issues using fewer tags and a simpler configuration, but may not provide exact information about which tag or tags have a bad status.
    4. To determine which rows are in bad status, use a TopView client like Remote Viewer, or go to Values View in TopView Admin Tools overview page for the configuration.
  2. Detect individual bad statuses:
    1. Create a row for the tag and set the alarm condition to "?" (bad status) and uncheck "Check for Good Status" option  
    2. Configure Tag Group or individual tag notifications for this alarm.
    3. This allows detection of individual bad status alarms and allows your notification to specify the exact tag with bad status.
  1. Do not "OR" the bad status condition ("?") with another alarm condition. OR'd alarm conditions require mutually exclusive conditions to ensure alarm states transitions are consistent.
  2. If you do not want alarms when a tag has a bad status value, use the "Check for Good Status" option in the tag's Alarm Limits and Notifications settings to prevent alarms from occurring when a status is bad.
