Loss of Data in DNP3 Networks

DNP3-based networks can be very powerful in managing an industrial network, with its timestamping, messaging, and historic archiving features being highly configurable to suit specific requirements. However, if configured improperly, valuable data can be lost.
In this video, we show how data can be lost in a DNP3-based industrial network, its' impact to operations, and three areas that you can investigate to resolve such issues.

Seems like the SCADA server should be checking the timestamps of the events and alerting if event(s) are in the past (outside an acceptable window) and not writing the erroneous data to the historical database. Simply store them to some anomaly event log and not corrupt the historical database data.

You've raised a good point. The historic data is one of the DNP3 feature as an industrial communication protocol. It mitigates the risk of comms failure by storing events in the outstation controller and upload the event data the SCADA server (DNP master). Depending on the server software, for example, GeoSCADA (ClearSCADA) can be configured to ignore the historic events passed a certain period. However, most of the application servers are configured to accept the events to avoid loss of data. We share another video with you: czcams.com/video/SmRI4H1LqsQ/video.html
