IE-CS(T)-2TX-xRS232/485
TCP Server 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: The IE-CS(T)-2TX-xRS232/485 will automatically close the TCP connection if there is no TCP
activity during this given time. After the connection has closed, the IE-CS(T)-2TX-xRS232/485 will start
"listening" for another host's TCP connection.
Inactivity time
Setting
0 to 65535 ms
0 ms: TCP connection is not closed due to an idle serial line.
0-65535 ms: The IE-CS(T)-2TX-xRS232/485 automatically closes the TCP connection if there is no serial data
activity during this given time. After the connection has closed, the IE-CS(T)-2TX-xRS232/485 will start
"listening" for another host's TCP connection.
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 IE-CS(T)-2TX-xRS232/485 will check the connection status
between the IE-CS(T)-2TX-xRS232/485 and remote host by sending "keep alive" packets periodically. If the
remote host does not respond to the packet, the IE-CS(T)-2TX-xRS232/485 assumes that the connection was
closed unintentionally, the IE-CS(T)-2TX-xRS232/485 will then force the existing TCP connection to close.
ATTENTION
The Inactivity time should be larger than that of the Force transmit timeout. To prevent unintended data loss
due to session disconnection, it is highly recommended that this value is set large enough so that the intended
data transfer can be completed.
