As with most “fieldbus” drivers, the status of an OpcNetwork is either the normal “ok” or less typical “fault” (fault might result from licensing error). The Health slot contains historical timestamp properties that record the last network status transitions from ok to any other status. The “Fault Cause” property further explains any fault status.

As in other driver networks, the OpcNetwork has an available “Alarm Source Info” container slot you can use to differentiate OpcNetwork alarms from other component alarms in the station. See “About network Alarm Source Info” in the Drivers Guide for more details.
