AWK-1121/1127 Web Console Configuration
3-32
When Mode is set to TCP Client on a serial port’s Operation Modes page, you will be able to configure
additional settings such as TCP alive check time, Inactivity time, and Ignore jammed IP.
TCP Alive Check Time
Setting Description Factory Default
0 to 99 min. This field specifies how long the AWK-1127 will wait for a
response to “keep alive” packets before closing the TCP
connection. The AWK-1127 checks connection status by
sending periodic “keep alive” packets.
0: The TCP connection will remain open even if there is no
response to the “keep alive” packets.
1 to 99: If the remote host does not respond to the packet
within the specified time, the AWK-1127
will force the existing
TCP connection to close.
7 min.
Inactivity Time
Setting Description Factory Default
0 to 65535 ms This field specifies the time limit for keeping the connection
open if no data flows to or from the serial device.
0: The connection will remain open even if data is never
received. For many applications, the serial device may be idle
for long periods of time, so 0 is an appropriate setting.
1 to 65535: If there is no activity for the specified time, the
connection will be closed. When adjusting this field, make sure
that it is greater than the Force transmit time. Otherwise, the
TCP connection may be closed before data in the buffer can be
transmitted. Connection Control must be set to “Any
character/Inactivity time” for this setting to have effect.
