OEE Circle Widget
Summary
The OEE circle widget displays the percentage of time a tag has spent in one or more states, in the form of a donut chart. It can also show how many times a tag has transitioned into or out of each state. You can define custom time periods (e.g., specific hours, days, or weeks) to scope the specific data to be included, such as to exclude weekends.
This widget is commonly used to visualize machine utilization and productivity based on real operational data by defining states such as “On,” “Off,” or “On Load” in a tag’s properties. Note that in order to display a tag using this visualization, that tag MUST have at least one State Property configured. Learn how to define states in our Intro to Properties and States Properties articles.
Examples at a glance
Showing the percentage of time a temperature sensor was either in a 'Hot' or 'Cold' state, as defined in the tag's States Properties.
Common applications
- Compare the percentage of time each machine spends “On Load” during day, evening, and night shifts to identify productivity differences across teams.
- Count how often equipment transitions between “Off” and “On” states to identify excessive cycling that could indicate wear or control issues.
- Use standardized states (e.g. “Running,” “Fault,” “Maintenance”) to compare machine performance between facilities or production lines.
Interface breakdown
Hover over an OEE circle widget, click the Configure Widget button (
), and select the tag you wish to analyze. Then, click ‘Next’ to proceed to the options panel below.
- Unit of aggregation: Choose the time span over which your data is grouped. Options include Day, Week, Month, or Shift.
- Day/Week/Month: Group data into units of the selected calendar period. Use the following UI element, ‘Select configured periods’ to exclude nonworking hours or weekdays if desired.
- Shift: Group data into custom work periods that you define. This is useful for work schedules that do not align to calendar days. This selection enables you to create multiple configured time periods as needed.
- Select configured periods: Choose a preset from the dropdown or select ‘Custom’ to configure specific windows of data to include in the visualization. For example, the time period below would include only data from 9:00 AM to 5:00 PM Monday through Friday in your report. Add additional time periods to model more complex schedules.
- Timezone: Set the timezone you’d like the widget to apply when processing the timeslots above. ‘Default to current timezone’ will use your computer’s current settings.
- Reporting: Select whether you would like to analyze your data based on ‘States’ or ‘Counts’
- Use States to interpret continuous/analog data. For example, you can track how long a machine is in ‘Active’, ‘Idle’, and ‘Off’ states each day based on its power consumption.
- Counts is not currently implemented for this widget, and will display ‘Not Available’.
- States With Intervals: Turn on ‘With Intervals’ to display the percentage of time that a tag is in each selected state. This can help you answers questions like, ‘What percentage of time is the drill press idle each shift?’
- Use the checkboxes to show or hide various states. If you have selected a tag with no states configured, use the shortcut (
) to create at least one States Property for this tag. - Note that ‘Total Time’ is not currently implemented for this widget, and will not impact the visualization if selected.
- Use the checkboxes to show or hide various states. If you have selected a tag with no states configured, use the shortcut (
- States With Transitions: Turn on ‘With Transitions’ to display the number of times that a tag enters and exits each selected state. This can help you answer questions like, ‘How many times does the drill press activate each shift?’
