3.7.4 Network Modules
ETHERNET Interface Modules
The modules QJ71E71/E71-100 and QD71E71-B2 are used on the PLC side to connect a host
system, e.g.a PC or work station and the System Q via ETHERNET. Besides the data transfer
via TCP/IP or UDP/IP communications the reading and changing of PLC data as well as the
monitoring of CPU module operation and control status is supported.
Special features
쎲 Network types: 10BASE5, 10BASE2 or 10BASE-T
쎲 Transfer rate of 10/100Mbit/s
쎲 FTP-server functionality
쎲 The communication function using fixed send and receive buffers is
available.
쎲 Up to 16 communication lines can be opened for concurrent data com-
munication.
쎲 PLC programming and monitoring can be performed from GX Devel-
oper or GX IEC Developer on a personal computer via ETHERNET.
MELSECNET Modules
The modules QJ71BR11 and QJ71LP21 are used to connect the MELSEC System Q to a
MELSECNET/10 or MELSECNET/H network.This enables fast and effective communications
between PLCs of the Q, QnA and QnAS series.
Special features
쎲 Two different topologies are featured: Coaxial bus (QJ71BR11) or
redundant optical loop (QJ71LP21).
쎲 High data transfer rates: 10 Mbit/s with coaxial bus systems and
optional 10 or 20 Mbit/s with optical loop systems
쎲 Communications with other PLCs, PCs, or remote I/O
쎲 The network system supports data communications between any two
stations, no matter how many networks lie between them
쎲 Station separating functionin coaxial bus system and loop back func-
tion in optical duplex loop systems in case of a station malfunction
쎲 Control station shifting function and automatic return function
