1 OVERVIEW
1.1 Features
(1) Many controllable input/output points
As the number of input/output points accessible to the input/output modules
loaded on the base units, 256 points (X/Y0 to FF) are supported by the
Q00JCPU and 1024 points (X/Y0 to 3FF) by the Q00CPU/Q01CPU.
Up to 2048 points (X/Y0 to 7FF) are supported as the number of input/output
device points usable for refreshing the remote input/output of CC-Link and the
link inputs and outputs (LX, LY) of MELSECNET/H.
(2) Lineup according to program capacity
The optimum CPU module for the program capacity to be used can be selected.
Q00JCPU, Q00CPU : 8k steps
Q01CPU : 14k steps
(3) Fast processing
The LD instruction processing speeds are the following values.
Q00JCPU : 0.20µs
Q00CPU : 0.16µs
Q01CPU : 0.10µs
In addition, the high-speed system bus of the MELSEC-Q series base unit
speeds up access to an intelligent function module and the link refresh of a
network.
MELSECNET/H link refresh processing : 2.2ms/2k words 1
*1 This speed only applies when the SB/SW is not used with the Q01CPU and
the MELSECNET/H network module is used as the main base unit.
(4) Increase in debugging efficiency through high-speed
communication with GX Developer
The RS-232 interface of the Basic model QCPU enables program write/read or
monitor at a maximum of 115.2kbps.
(5) Saved space by a reduction in size
The installation area of the Basic model QCPU is about 60% of that of the AnS
series.

(6) Connection of up to four/two extension base units
(a) The Q00JCPU can connect up to two extension base units (three base units
including the main) and accepts up to 16 modules.
(b) The Q00/Q01CPU can connect up to four extension base units (five base
units including the main) and accepts up to 24 modules.
(c) The overall distance of the extension cables is up to 13.2m to ensure high
degree of extension base unit arrangement.
POINT
When bus-connecting the GOT, the number of extension base units connected
decreases by one since the GOT uses one stage of the above base units.
(7) Serial communication function for communication with personal
computer or display device
With the RS-232 interface of the Q00CPU or Q01CPU connected with a personal
computer, display device or the like, the MELSEC communication protocol
(hereafter refered to as the MC protocol) can be used to make communication.

Communication in
MC protocol
Personal computer,
display device
The serial communication function only allows communication in the MC protocol
(QnA-compatible 3C frame (format 4), QnA-compatible 4C frame (format 4, 5)).
The serial communication function does not allow communication in the
nonprocedure protocol or bidirectional protocol.
Refer to the following manual for the MC protocol.
• Q Corresponding MELSEC Communication Protocol Reference Manual
(8) Built-in standard ROM
The flash ROM for storing parameters and sequential program is installed as a
standard feature for easier protection of important program.
(9) Easy operation of CC-Link system
The I/O signals for up to 32 remote I/O stations can be controlled without
parameters when one master module of the CC-Link system is used.
The remote I/O stations can be controlled in a similar manner to controlling the
input/output modules installed on the base unit.
(10) Blocking an invalid access using the file password
Program can be prevented from being altered through invalid access by
presetting the access level (reading prohibited, writing prohibited) in the file
password.

The program stored on the standard ROM is booted (read) to the program
memory of the Basic model QCPU and executed.
Booting a program from the standard ROM to the program memory requires boot
file setting in the PLC parameter.
