Menu Default Description
When UDP packets are received to the socket number waiting for a connection,
data is sent to the serial port, and data entered into the serial port is made into
UDP packets and sent to the Client.
UDP Client
When data is entered into the serial port, sends UDP packets to the IP and socket
number of the set server. Set the IP and port number of the server to which you
want to request access at [Target IP/Port].
Local Port 4001
Specify the socket number assigned to the port. Use this port to wait for network
socket connection in TCP Server and UDP Server mode.
Target IP 0.0.0.0
Specify the IP address of the destination to connect to in TCP Client and UDP
Client mode.
Target Port 4001
Specify the port of the destination to connect to in TCP Client and UDP Client
mode.
Latency
Time 0
Set if you want to send continuous incoming data from the serial port to the
socket at once.
For example, if a serial device sends 100 bytes of text and the socket is sent to
the server via sLAN/all PoE, with this value set to 0, data entered in bytes at a
time is immediately passed to the server via the socket. This guarantees real-time
performance but causes a lot of traffic to the network, sending lots of packets to
the server.
If this value is set to a non-zero value, the data received several bytes at a time is
buffered, waited for a set amount of time, and read again. If any data is received,
it is re-buffered, otherwise it is considered all received and sent in batches to the
socket. There are no traffic problems caused by many packets, but real-time
performance is not guaranteed.
TCP Alive
Check Time
60
After the socket connection is complete, check the network status at the set time
interval to terminate or reset the socket connection if a network abnormality is
determined.
(If set to 0, this feature is not used. Value can be set from 0 to 65535 sec)
If the initial value is set to 0, this feature is not performed and keep the socket
connection.
TCP No-
delay
Disable
When TCP communication, it decides whether to collect the data sent and
received over Ethernet fist and process it together or process it immediately.
When set to Disable, TCP send/receive data will be collected and processed,
which results in a delay between Ethernet and serial transmission. But it is
beneficial for high speed data transmission and packet-unit data transmission.
When set to Enable, TCP send/receive data will be processed immediately. This
minimizes the delay between Ethernet and serial transmissions, but
disadvantages high speed communication and packet-unit data transmission.
