Settings for TCP Server Mode
When Mode is set to TCP Server on the Operation Modes page, you will be able to configure
additional settings such as TCP alive check time, Inactivity time, and Max connection.
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 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.
