they create. Possible reasons for monitoring Connection status include: An application or ConnectionManager monitors ConnectionEndpoints on AutomationComponents to decide whether it needs to (re)establish or close Connections . For example ... Vendor-specific diagnostic applications monitor Connections defined in ConnectionConfigurationSets on a ConnectionManager and the ConnectionEndpoints on AutomationComponents to present comprehensive Connection information to the operator or engineers, including identification information
