An operating state is a group of data set- and tag-collection properties that a device implements under specific conditions. For example, you might want to collect data from equipment more frequently when the equipment is under a heavy load than when it is idle. If you define an operating state, the device that monitors this equipment can detect when the heavy-load condition is active and implement a different set of data set collection properties in response. Consider the following simplified example, where a data group whose sensors monitor a turbine has two operating states:

Operating States Settings
Run-Up
  • Enter state when RPM rises above 200
  • Collect a data set every 30 seconds
  • Write data sets whose length is 10 seconds
  • Exit state when speed is above 1200 RPM for 20 seconds or speed is less than 200 RPM for 20 seconds
Default
  • Collect a data set once per hour
  • Write data sets whose length is 4 seconds, including 1 seconds of pre-trigger data

Transitions between Operating States

Defining an operating state for unique equipment conditions allows the device to dynamically switch between collection behaviors. As the Run-Up operating state in the previous example shows, operating state properties express when the data group enters the state and starts applying data set- and tag-collection properties, as well as when the data group exits the operating state.

How Operating States Affect Data Visualization

The metadata pane on the Data Viewer page displays the operating state that was active when the device collected the data.
