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.

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.

RS-232 cable

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.
