Introduction of 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, serial to Ethernet converter USR-TCP232-410S will send Keep Alive package in every 15 second to check TCP connection and USR-TCP232-410S will disconnect and reconnect to server if any connection exception occurs. TCP Client mode also supports baud rate synchronization, USR Cloud and Modbus gateway.
 
TCP Client of serial to Ethernet converter USR-TCP232-410S
 

USR-TCP232-410s 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.

 

When serial to Ethernet converter works as a Modbus TCP Client, how many TCP Servers it can connect to?  Take serial to Ethernet converter USR-TCP232-410S as an exaple, when USR-TCP232-410S works as a modbus tcp client, it can only connect to one tcp server.

When serial to Ethernet converter works as a TCP server, how many TCP client it can connect to? Take serial to Ethernet converter USR-TCP232-410S as an exaple, when USR-TCP232-410S works as a TCP server, it can connect up to eight TCP clients.
