# Close an On Top Display

The application reads the value of the connection and closes the graphic display whose display number corresponds to the value. If you want to use global connections, you must make sure that each display has its own unique number.

Replace displays and non-replaceable On Top displays cannot be closed by a remote display change. If the display number represents a Replace display or a non-replaceable On Top display, the close action is ignored and an error message is logged to Diagnostics.

A read only connection. Assign an analog tag to this connection.
