4.2.3. Transient connection
This connection, called transitory due to its short-lived nature. If the serial port or network port receives none data within the setting
time, the connection will be automatically disconnected. The gateway used to send serial device data back to a control room or a
cloud application need to open a remote connection before they can transfer the serial data. When the transmission is completed, the
gateway should immediately close the connection. Without support for flexible connection control, you would need to spend extra
time handling connections at the central site or cloud application.
TCP transient connection is used primarily to save server resources. Fig.41 shows an example of configuration setting for transient
connection in TCP Client working mode under the socket page.
