2.2.1.TCP Client
Figure 6 TCP Client
TCP Client provides Client connections for TCP network services. TCP Client device will connect to server to
realize data transmission between the serial port device and server. According to the TCP protocol, TCP Client
has connection/disconnection status differences to ensure reliable data transmission.
TCP Client mode supports Keep-Alive function: After establishing connection, 410s will send Keep-Alive package
in every 15 second to check TCP connection and 410s will disconnect and reconnect to server if any connection
exception occurs. TCP Client mode also supports baud rate synchronization, USR Cloud and Modbus gateway.
410s works in TCP Client mode needs connect to TCP Server and needs set the parameter: Remote IP/Port. 410s
works in TCP Client won’t accept other connection request except target server and will access server with
random local port if configuring local port to 0.
