The actual communication speed (effective communication speed) may be
affected by power line conditions (structure of equipment, length of lines, etc.),
other electrical appliances, and network conditions.
UDP is a data communication protocol used on the Internet, and although the
data communication reliability of UDP is low, processing is simple and the
communication speed is fast, and thus UDP is often used for video streaming.
TCP is also a data communication protocol used on the Internet, and although
TCP is slower than UDP, it has higher reliability and thus is commonly used for
general communication.
*2
Measured using FTP from a Windows
®
PC to a Linux
®
server.
*3
The maximum number of adapters is a recommended value. As the number of
PLC adapters and other devices connected to the network increases, the
communication speed slows.
