Managing Curves in the Curve Tool

Use the Curve Tool for managing curves, including creating, editing, viewing, downloading, uploading, importing and exporting.

Managing Permanent Curves

A permanent curve is a curve either created in the Curve Tool or using the Curve Add (82) command with the Permanent life cycle. Permanent curves are synchronized between the controller and project file using the Curve Tool. Permanent curves are also saved to the flash memory in the controller when a Flash Update is initiated. See Updating Flash for details.

The permanent type curves in the Curve Tool are uploaded and downloaded as an entire set.

Click the Download Curves to Controller button to download the entire set of curves in the project into the controller, replacing all permanent curves in the controller. It will leave temporary curves unaffected, except that temporary curves whose curve IDs matched a downloaded curve will be overwritten.
Click the Upload Curves from Controller button to upload the entire set of permanent type curves from the controller into the project, replacing all curves in the project. Temporary curves are not uploaded into the project.

The Sync column in the Curves In Project and Curves in Controller windows is used by permanent curves to indicate the differences between the curves in the project and in the controller as follows:

	The curve exists both in the project and the controller, but the two curves are different.
	The curve exists only in the project. Download to copy the curve into the controller. Upload to delete the curve from the project.
	The curve exists only in the controller. Upload to copy the curve into the project. Download to delete the curve from the controller.

Managing Temporary Curves

A temporary curve is a curve that is created using the Curve Add command with the Standard, Start-Once, or Complete-Once life cycle. Temporary curves are not saved to flash memory or in the project file, and can be can be viewed but not edited in the Curves in Controller window in the Curve Tool.

A temporary curve can be copied into the project, making the copy a permanent type curve. To copy a temporary curve into the project, select a temporary curve and click the Copy Curve to Project button on the toolbar.

Creating and Editing Curves

These are basics of creating and editing curves in the Curve Tool. For more details, see the Curve Tool Overview topic.

Create a New Curve

In the toolbar, click the Create New Curve button. The new curve will appear in the Curves in Project window.
In the Properties pane, on the Curve tab, in the Name cell, enter a name for the new curve. You may also enter a Description.

Add Curve Points

In the spreadsheet located below the curve graph view, in the right-most column, enter the X value and Y value for the new point, then press Enter. Curve data can be copied and pasted from spreadsheets programs as described in the Copying and Pasting section in the Curve Tool topic.
Continue adding points by entering the X values and Y values in the right-most column. Even if the point is not going to be the last point in the curve, you must enter it in the right-most column. After entering the X and y values, the new point column will automatically be placed in the correct location in the spreadsheet.

Edit Curve Points or Properties

To edit the points, simply edit the desired X values and Y values in the spreadsheet. Clicking a point in the graph view will highlight the point in the spreadsheet view, making it easy to find.

Set the properties of the curve on the Curves tab in the Properties pane. See Curve Properties for details.

Download Curves to the Controller

In the toolbar, click the Download button. This will download the curves in the project to the controller, overwriting the existing curves.
