Abstract

A software product and method of monitoring a field device in an enterprise having an industrial process. A subscription to the OPC DA server for diagnostic data from the field device is made and a subscription to an OPC AE server for event notifications from the OPC AE server is made. The subscription to the OPC AE server is activated, but the subscription to the OPC DA server is not activated. When an event notification is received from the OPC AE server, the subscription to the OPC DA server is activated. Diagnostic data from the field device is received and device health information from the diagnostic data is generated. The device health information is displayed on a viewing monitor. The subscription to the OPC DA server is then deactivated.
