# Enter Handshake

A read connection. You can assign a tag or an expression to this connection. This connection resets the Enter connection, using the HandshakeResetType property specified in the Properties dialog box. 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 HandshakeResetType property.
