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.
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.
