The Q series Ethernet modules include the E-mail communication
function as standard. You can transfer production information
to/from anywhere in the world and configure a remote
monitoring/controlling system easily. For the Intranet, the FTP
server function and MC protocol perform program download/upload
easily.
The high-performance model QCPU has introduced a remote
password function to provide security for remote operations.
A remote password is changed/deleted from a local CPU.
A serial communication module (RS-232/422) connected to a
personal computer has a function to automatically send data from
the PLC to the personal computer when a given condition holds.
Also, on Ethernet, this function can be used for E-mail
transmission. Use of this function permits rapid transmission of
alarm occurrence information, etc., without waiting for polling from
the personal computer.
The MX series communication support software packages are
software tools for Windows
®
for easy connection of a host
monitoring/controlling personal computer to the Q series
(connection to QnA, A or FX series also possible). You can easily
create a monitoring/control application on Visual Basic
®
,
Visual C
++
®
or Excel
®
, without being conscious of the different
complicated communication protocols of Ethernet,MELSECNET/H,
CC-Link, RS-232 serial communication or CPU programming port
(RS-232 or USB).
Supporting the VBScript language, MX Component (Ver. 2 or later)
can configure a remote monitoring/operating system via the
Internet/intranet using Internet Explorer
®
. For example, when the
Web pages using VBScript are made available by a factory,
specifying the URL of that factory from a remote location enables
remote monitoring/operation to be performed to the factory via the
Internet/intranet.

The Q series Ethernet, MELSECNET/H and CC-Link have achieved seamless access beyond the differences in network type and network
hierarchy. Data can be transferred between any networked PLCs and monitored/programmed with the GX Developer-installed personal
computer connected to the PLC.
(Note 1)
The Q series has a wide assortment of personal computer boards
compatible with the MELSECNET/H network system. These
boards maintain the upward compatibility of the conventional
MELSECNET/10 board, and use the dedicated software package
for board setting to simplify troublesome work. Furthermore, the
RAS functions installed ensure ease of error detection.
The high-performance model QCPU can configure a remote I/O
network using the Q series I/O for large-scale, large-capacity,
centralized management and distributed control. It can also
configure a multiple remote I/O network.
In addition to 10Mbps compatible with the conventional
MELSECNET/10, the MELSECNET/H has a choice of two
operation modes: the MELSECNET/H mode having Max. 25Mbps
transmission rate; and the MELSECNET/10 mode compatible with
the conventional A/QnA series. In the MELSECNET/H mode, link
scan time is as short as 10ms on a network of a total of 8 stations
having 2k link relay points and 2k link register points.
