Mitsubishi MELSEC System Q

3.7.2 Open Networks
Open networks are manufacturer independent, i. e. those networks are also used by other
manufacturers. Thus the communication between a MELSEC PLC and devices of third-party
manufacturers is possible.
ETHERNET
ETHERNET is the most widespread network for connection of information processors such as
personal computers and work stations.ETHERNET is a platform for a very wide range of data
communications protocols. The combination of ETHERNET and the extremely widespread
TCP/IP protocol enables high-speed data communications between process supervision sys-
tems and the MELSEC PLC series.
TCP/IP provides logical point-to-point links between two ETHERNET stations. Using the
TCP/IP protocol a process supervision system can request up to 960 data words per query if
the MELSEC System Q module is used.
