# Value

A read-write connection. Assign a tag to this connection. When the operator presses the button, the application writes the value corresponding to the latched state (State 1) to the tag’s data source, unless the LatchResetType property is "Non-zero" and the Handshake connection is currently a non-zero value.

When the Handshake connection unlatches the button, the application sends the value corresponding to the unlatched state (State 0) to the Value connection.

When you open a display containing a latched push button, the application reads the value of the Value connection to determine its current state.

Tip: | To provide visual feedback that the Value connection has been read by the data source, assign different tags to the Value and Indicator connections. Configure the data source to pass the Value connection’s value to the Indicator connection.
