Add history collection

The DeltaV subsystem collects historical data on parameter fields to which you add collection. You can add history collection to module parameter fields.

Open the module.
Select the parameter, either at the module level or for a function block within the module.
Right-click, and then click Add History Recorder.
Complete the fields on the General and Advanced tabs. Click the Help button on the dialog for further information.
Click OK.

Important

To add a floating-point array item to history collection, enter the parameter path as Module/ArrayParameterName[row,col].field.

However, when downloaded to the DeltaV Continuous Historian, the parameter is specified as Module/ArrayParameterName[row][col].field. When downloaded to the Advanced Continuous Historian or PI Server, the parameter is specified as Module/ArrayParameterName(row)(col).field, because these historians do not support the use of brackets.

These syntax distinctions are important when you are configuring a Process History View trend for the array parameter. When configuring a pen in Process History View for the DeltaV Continuous Historian, use brackets to specify the array parameter path as Module/ArrayParameterName[row][col]. When configuring a pen in Process History View for the Advanced Continuous Historian or PI Server, use parentheses to specify the array parameter path as Module/ArrayParameterName(row)(col).
