Set Value Hotbox Drawing Method
Available in all applications
Used by: Analog Output, Analog Control, Digital Output, Digital Control, Selector Switch.
The Set Value Hotbox tag drawing method is identical in function to the Set Value Button drawing method. The difference is only in its appearance in your applications. Where the Set Value Button drawing method creates a click-able button, the Set Value Hotbox creates only a rectangular hotbox marking an area where the operator can click. It is up to you to make it clear to the operator what will happen when the hotbox is clicked.
One way that this drawing method might be used is superimpose hotboxes over an image of equipment from your facility. The boxes should be located over the controls familiar to the operators.
The graphic editor to configure the Set Value Hotbox will appear as follows. Note that the confirmation dialog option is available only when writing a 1 or 0 immediately, or when executing the last set up value.

The Tag field displays the name and description of the tag that is currently associated with this drawing method. You can use this to select a different tag or parameter to use as the data source for this drawing method.

Write 0 Immediately / Write 1 Immediately
Choose one of these radio buttons if you want the completed button to write a value of 0 or 1 to the PLC or RTU when it is clicked.
Set Up 0 For Next Execute / Set up 1 For Next Execute
Choose one of these radio buttons if you wish the completed button to set up a value of 0 or 1 to be sent to the associated equipment.
This will not result in the completed button sending a value to the PLC or RTU when it is clicked; rather, it will latch the button on, set the value in memory and wait for a command to execute this value. A second button should be configured with the Execute Last Set Up Value radio button selected.
When the second button (Execute Last Set Up Value) is clicked, the value in memory will be sent to the associated equipment, and the first button will be latched off.
The Execute Last Set Up Value radio button can be selected if you wish the completed button to transmit the last set up value to the associated equipment.
The Execute Last Set Up Value option requires at least two Set Value Button objects. The first button should be configured with either the Set Up 0 For Next Execute or Set Up 1 For Next Execute radio button selected. When the first button is clicked, it will be latched on, and the associated value (0 or 1) will be set up in preparation for a command to execute. When the second button (Execute Last Set Up Value) is clicked, the value will be transmitted to the equipment, and the first button will be latched off.
The Cancel Last Set Up Value radio button can be selected if you with the completed button to cancel the last set up value to the associated equipment. A set value button with this option should be drawn whenever you have also drawn one with the Set Up … for Next Execute option set.
Opens the Select Color Dialog from which you can select a color from the VTS palette to be displayed when the mouse pointer is within the area of the hotbox. To reduce confusion, you should consider making this a different color than that of the Page Hotbox.
Available only when the button is configured to write a 1 or 0 immediately, or to execute the last set up value. When checked, the operator will be prompted to confirm the control action. The message in the dialog box will be a variation of the following example, depending on the control action selected.
