TCP Client Mode

TCP alive check time
Setting
0 to 99 min
0 min: TCP connection is not closed due to an idle TCP connection.
1 to 99 min: NPort 5200 automatically closes the TCP connection if there is no TCP activity for
the given time.
Inactivity time
Setting
0 to 65535 ms
0 ms: TCP connection is not closed due to an idle serial line.
0-65535 ms: NPort 5200 automatically closes the TCP connection if there is no serial data activity
for the given time.
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 5200 will check the connection
status between the NPort 5200 and remote host by sending "keep alive" packets periodically. If
the remote host does not respond to the packet, NPort 5200 assumes that the connection was
closed down unintentionally. NPort 5200 will then force the existing TCP connection to close.
The Inactivity time should at least be set larger than that of Force transmit timeout. To prevent
the unintended loss of data due to the session being disconnected, it is highly recommended that
this value is set large enough so that the intended data transfer is completed.
