Set up connections for a Ramp button

In the

Graphics Display

editor, double-click the button to open its

Properties

dialog box.

Click the

Connections

tab.

Assign a tag to these connections:

A read-write connection. The application keeps a copy of the Value connection on the computer. When the operator presses the

Ramp

button, the application adds or subtracts the "Ramp value" amount (specified on the

General

tab) from the local Value connection value and writes the result to the Value connection tag’s data source.

If the "Ramp value" amount is a floating point value and the Value connection is an integer tag, the application rounds the value before writing it to the connection.

A read connection. Assign a tag or an expression. The application reads the connection to determine by what value the object will increase or decrease the data source.

This connection is only used if the

Use variable ramp

check box on the

General

tab is selected.

A read connection. Assign a tag or an expression. The application reads the connection value to determine the highest or lowest ramp value the object can write to the data source.

This connection is only used if the Use variable lower/upper limit check box on the

General

tab is checked.
