Configure the Spin Button Command and Navigation Properties
Scenario
You want to configure the Command and Navigation properties of a Spin button in order to increase or decrease the Present Value property of an Analog Output data point, from within your graphic.
NOTE:
If you create a command control element in a symbol instead of on a graphic, follow the steps below, replacing the Target and any other hard-coded references with * substitutions in the Evaluation Editor. For more information, see Symbol Property Substitutions.
- You have reviewed the Command and Navigation properties section and have a full understanding of the fields and the options available to you for configuring the Command and Navigation properties group.
- You have drawn a Spin button control on the graphic and configured the Command Control properties.
- In the Properties view (Spin Button Control properties), expand the Command and Navigation properties group.
- In the Target field, drag a designated data point from System Browser. If the target designation does not specify a property, the default property is targeted. Otherwise you must specify the property by typing a period (.) and then the property name after you drag the data point into the Target field, for example:
CCProject.LogicalView:Logical.PXRack.B.Block.Hcrv
;.Property_Name.
- For this example, drag the Analog Output data point into the Target field. No property extension is required, as the default property is .Present_Value.
NOTE: If you have the data point selected in System Browser, or you have selected a symbol instance of the data point on the canvas, the data point information is displayed in the Operations and Extended Operations tab, from there, drag the property you want to target into the Target field. The property name is added automatically.
- From the Command Name drop-down menu, select or type the command rule that you want to apply to the property.
- For this example, select or type Write.
NOTE: The command name must match the name of the command in the Models and Functions Command Configuration section. This field is case-sensitive.
- In the Parameter field, do one of the following:
- Select the value from the drop-down menu.
NOTE: For a stand-alone command control, if you have multiple parameters, only one parameter receives the value from the control itself and all other parameter values must be hard-coded.
- For this example, delete everything but the parameter name, which in this case is: Value.
- From the Trigger drop-down menu, select how to initiate the command: Single click or Double click.
- In this example, select Single Click.
- (Optional) In the Description field, type a brief description of the command that will appear in the tooltip.
- In the Element Tree view, click the Thumb elements ([up] and [down] buttons) of the Spin button, and in the Property view navigate to the Command and Navigation property section and from the Cursor drop-down menu, select the cursor preference that you want to display when the command is active. The cursor must be set in the Thumb element properties, if you want the specified cursor to display when the cursor moves over the thumb.
- Select the Command Trigger check box to enable the command control to send a command.
- (Optional) To disable the command control, select the Disabled check box, and from the Disabled Style drop-down menu, select how the disabled command control displays when disabled. For example, if the selected data point is
Out_of_Service
and the command is disabled, the selected disabled style will be active at runtime to reflect this.
- The Extended Tooltip check box is selected by default. It displays the following command object details: Target, Command Name, and Parameter. If enabled, the extended tooltip is added to any existing tooltips configured for the element.
- Click Save As .
- To test the Spin button in Runtime mode, from the Home tab, in the Modes group, select Runtime mode .
- If you created a symbol and want to designate it as the default command symbol for an object type, proceed to Designating and Adding a Default Command Symbol to a Graphic.
