5-13
TCP Server Mode
TCP alive check time
Setting Factory Default Necessity
0 to 99 min 7 min Optional
0 min: TCP connection is not closed due to an idle TCP connection.
1 to 99 min: The NPort 5100 automatically closes the TCP connection if there is no TCP activity
for the given time. After the connection is closed, the NPort 5100 starts listening for another host’s
TCP connection.
Inactivity time
Setting Factory Default Necessity
0 to 65535 ms 0 ms Optional
0 ms: TCP connection is not closed due to an idle serial line.
0-65535 ms: The NPort 5100 automatically closes the TCP connection if there is no serial data
activity for the given time. After the connection is closed, the NPort 5100 starts listening for
another host’s TCP connection.
This parameter defines the maintenance status as Closed or Listen for the TCP connection. The
connection is closed if there is no incoming or outgoing data through the serial port during the
specific Inactivity time.
If the Inactivity time is set to 0, the current TCP connection is kept active until a connection close
request is received. Although Inactivity time is disabled, the NPort 5100 will check the connection
status between the NPort 5100 and remote host by sending “keep alive” packets periodically. If the
remote host does not respond to the packet, NPort 5100 assumes that the connection was closed
down unintentionally. NPort 5100 will then force the existing TCP connection to close.
