Configuring Production Counting Calculations

  1. Create or edit a variable.

  2. In the Variable Sheet, make sure the Data Source, Event Type, Sampling Interval, Sampling Offset, Sampling Type, and Input Tag are visible. Click the Column/Row Visibility icon in the Variable Sheet window toolbar to change column visibility. The Column/Row Visibility dialog box appears.

  3. Select the appropriate columns in the Hidden list and move them into the Visible list by clicking the button.

  4. Close the Column/Row Visibility dialog box to return to the Variable Sheet window.

  5. In the Variable Sheet, select a Data Source of Historian, an Event Type of Time, a Sampling Interval of 0, a Sampling Offset of 0, and a Sampling Type of Raw Count. This Sampling Type is designed to count event archived in the historian, so would be appropriate for some types of pulse counters.

  6. Under the Input Tag column, identify an input tag. You may type the name of a tag if it is known, or you may search for a tag using the Tag Search. To use the Tag Search select the Input Tag column; right-click and click Tag Search.

  7. Search for an appropriate tag, select a tag from the search results, and click OK. The selected tag will appear in the Input Tag column.

  8. To save the variable, select the Save icon in the Variable Sheet window toolbar.
