Question 9

A sensor reads potentially critical data from an industrial device, but most of the data from the sensor is not critical information and does not change unless a critical event happens.

Which data work flow is appropriate for how the critical and non-critical data is processed?

Select an option, then click Submit answer.

  • ○

    1. Acquire sensor data.
    2. Filter non-actionable data.
    3. Perform action on data.
    4. Send critical data and action performed on data to cloud for storing.
     
  • ○
