Notę

This textbook mainly describes how to use MELSEC-Q Series Ethernet module.

In addition, for details ofthe Ethernet module, referto the relevant manuals.

1.1 Ethernet

The development of Ethernet was started by Xerox Pało Alto Research Center in the U.S. in 1973, and Ethernet has been approved as a network technology by ISO and ANSI/IEEE standards.

Lately it is widely used for networking gear and communication channel, etc. (¹1)

For actual network operation, hardware technique such as transmission lines which is defined by Ethernet (in the narrow sense) and communication technology for TCP/IP communication (protocol: a procedurę for data transmission) are necessary.
