NPort 5100 Series User’s Manual Web Console Configuration
5-17
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: NPort 5100 automatically closes the TCP connection if there is no TCP activity for
the given time.
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: NPort 5100 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 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.
ATTENTION
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.
ATTENTION
Inactivity time is ONLY active when “TCP connect on” is set to “Any character.”
Ignore jammed IP
Setting Factory Default Necessity
No or Yes No Optional
Previously, when Max connections > 1, and the serial device is transmitting data, if any one of the
connected hosts is not responding, it will wait until the data has been transmitted successfully
before transmitting the second group of data to all hosts. Currently, if you select Yes for “Ignore
jammed IP,” the host that is not responding will be ignored, but the data will still be transmitted to
the other hosts.
Packing length
Setting Factory Default Necessity
0 to 1024 0 Optional
Default = 0, The Delimiter Process will be followed, regardless of the length of the data packet. If
the data length (in bytes) matches the configured value, the data will be forced out. The data length
can be configured for 0 to 1024 bytes. Set to 0 if you do not need to limit the length.
