TCP Communications
The LS8000-3 accepts TCP (Transfer Control Protocol) connections on port 23
(Telnet) and port 1002. The Telnet port (Port 23) can be used by a telnet
client such as the one included with Windows to manually type commands.
On this port, commands can be sent a single character at a time, and must be
terminated with a carriage return. Port 1002 is designed to interface to a
computer or PLC. This port accepts whole commands (not a single character
at a time) and does not require a carriage return at the end of each command.
The commands entered on the Telnet port are identical to the RS-232/RS-422
commands. See the
Communication Protocol section for a complete listing of
commands.
UDP Communications
UDP is a connectionless protocol that has much less overhead than TCP.
This allows a much higher data rate for measurements. There are two ports
used in UDP communications, ports 1001 and 1002. Port 1001 is used to
receive commands and send responses to commands, and port 1002 is used
to send real-time measurement data.
The destination port for UDP messages (responses or real-time data) from the
LS8000-3 is the same as the source port of the message that initiated the
response. All responses to commands, such as responses to settings request
messages, are received on and sent from port 1001. All real-time data is sent
from port 1002. This separation allows you to create two separate sockets on
the host, one socket to send and receive commands, and a separate socket to
receive real-time data.
