Audit Trail on User Activities

In SCADA systems it is crucial to be able to monitor important actions performed in the process of the industrial plant. The IGSS V8 SCADA solution includes the new Audit Trail module that offers a thorough recording of important actions done by its system operators.

What is recorded

The Audit Trail module can easily be customized to record any of the following operator actions:

  • Acknowledgement of process alarms
  • Commands send to the process PLCs
  • Operators login or logout
  • Changes in data collection settings
  • Operator notes written - for example alarm notes or maintenance notes
  • Changes in analog alarm limits
  • System start/stop

The recorded audit trails are shown in a list in the Audit Trail window. Filtering in this list is flexible and can be performed on many different system parameters. This is useful to track certain operator actions and detect any irregularities in the process control. Below is listed some of the information available for each record of an audit trail:

  • Operator - which operator has performed the action
  • IGSS Object - which object is influenced
  • IGSS Operator station - from where has the action been performed
  • Action Type - what has been done
  • Approved by - which second person has approved the action
