4.5.2.5 TCP Server mode
When the serial server is configured as a TCP server, it waits for a connection initiated by another network device. User must
set the local TCP port number for which it will listen for the connection, and the industrial serial server provides the maximum
number of two concurrent connections. Incidentally, industrial serial server can be configured as a client or server. The TCP

Description
TCP keep alive interval shows how many seconds the unit waits during an inactive
connection before checking its status. If the unit does not receive a response, it will drop
that connection. The default is 0 minute.
When the network connection is determined to be idle, the duration of the control
network inactivity will cause the connection to be forcfully closed. The range of value is
from 1 to 65535 ms. The default is 0 ms
This parameter set the TCP port number on which it will listen for the connection and set
the maximum (up to two) acceptable number of connections. The range of value is from
1 to 4. The default is 1.
This parameter describes the TCP port that communicates with the connected device.
The setting slave and master destination IP parameters must use the same value to
achieve communication. The range of value is from 1 to 65535. The default is 5004 for
port 1, 5005 for port 2, 5006 for port 3 and , 5007 for port 4
