Set up connections for a String Input Enable button

In the

Graphics Display

editor, double-click the button to open its

Properties

dialog box.

Click the

Connections

tab.

Assign a tag or expression to these connections:

A write connection. Assign a tag that can support up to 82 characters (bytes). When the operator presses the

Enter

key, the application writes the alphanumeric string to the tag's data source.

If you do not assign the Value connection, at runtime when the operator presses the button the pop-up does not open.

A write connection. Assign a tag to this connection. This connection accepts values of 0 and 1 only. The connection determines how long the

Enter

key press is registered. Use this connection for Enter key handshaking.

A read connection. You can assign a tag or an expression to this connection. This connection resets the Enter connection, using the

Handshake reset type

option specified in the

Timing

tab. Use this connection for

Enter

key handshaking if you want the Enter connection to be reset when a value at the data source changes.

If you assign an expression, the application calculates the value of the expression and resets the Enter connection when the expression value meets the conditions of the

Handshake reset type

option.
