DNS Server
IP
When the destination computer is described by a domain
name, DNS server is required to resolve the domain name,
which specifies the IP of this DNS server. When the IP mode
is DHCP, the parameter is not specified and will be
automatically acquired.
Dest. Mode
Static, Dynamic
UDP working mode: if the destination computer is described
by a domain name, it’s best to choose the static mode; If
there are multiple computers in the LAN communicating with
networking products through UDP, it is best to choose
dynamic mode.
TCP server mode: this parameter must be dynamic.
TCP client mode: when IP mode is dynamic, the destination
IP is reconnected after the device is restarted, so that the
correct IP address can be obtained again. Otherwise, it will
do direct connection without automatically restarting the
device.
Transfer
Protocol
NONE, Modbus
TCP<->RTU,
Real_COM
NONE indicates that the data forwarding from the serial port
to the network is transparent; Modbus TCP<->RTU will
convert Modbus TCP protocol directly into RTU protocol to
facilitate coordination with Modbus TCP protocol; RealCOM
is designed to be compatible with the old version of
REAL_COM.
Keep Active
Time
0
～
255
(1) Choose 1~255, if the device is in the TCP client working
mode, the TCP heartbeat will be sent automatically for
every "keep alive time". This can guarantee the TCP
availability of links. When set to 0, there will be no TCP
heartbeat.
(2) Set to 0~254, when transformation protocol choose
REAL_COM protocol, the device will send a length of 0
to 1 content data for every " keep alive time " to
implement the heartbeat mechanism of Realcom. When
set to 255, there will be no Realcom heartbeat.
