Settings for TCP Client Mode
When Mode is set to TCP Client on the Operation Modes page, you will be able to configure
additional settings such as TCP alive check time, Inactivity time, and Connection control.
TCP Alive Check Time
Default
7 min
Options
0 to 99 min
Description
This field specifies how long the module will wait for a response to “keep alive”
packets before closing the TCP connection. The module 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 module will force the existing TCP connection to close.
Inactivity Time
Default
0 ms
Options
0 to 65535 ms
Description
This field specifies the time limit for keeping the connection open if no data
flows to or from the serial device.
0: The TCP connection will be kept active until a connection close request is
received, 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”
for this setting to have effect.
