MELSEC-Q

1.1 Features

High Performance model QCPU has the following new features:

1

(1) Controllable multiple I/O points

 

All High Performance model QCPUs support 4096 points (X/Y0 to FFF) as the

 

number of actual I/O points capable of getting access to the I/O module installed

 

on the base unit.

 

 

They also support 8192 points max. (X/YO to 1FFF) as the number of I/O

 

devices which can be used in the remote I/O stations such as MELSECNET/H

 

remote I/O NET, CC-Link data link and MELSECNET/MINI-S3 data link.

 

(2) Lineup according to program capacity

 

The optimum CPU module for the program capacity to be used can be selected.

 

Q02CPU, Q02HCPU

: 28k step

 

Q06HCPU

: 60k step

 

Q12HCPU

: 124k step

 

Q25HCPU

: 252k step

 

(3) Realised high speed processing

Depending on the type of the sequencer, high speed processing has been realized.(Example: when LD instruction is used)

Q02CPU: 0.079s

Q02HCPU, Q06HCPU, Q12HCPU, Q25HCPU : 0.034 s

In addition, an access to the intelligent function module or an increase in speed of the link refresh of the network have been realized by the connection system (System bus connection) of the newly developed base unit.

Access to the intelligent function module : 20s /word (approx. 7 times)1

MELSECNET/H link refresh processing : 4.6ms/8k word (approx. 4.3 times)1 1: Where Q02HCPU is compared with Q2ASHCPU-S1.

(4) Increase in debugging efficiency through high speed communication with GX Developer

In the High Performance model QCPU, a time required for writing/reading of a program or monitoring has been reduced through the high speed communication at a speed of 115.2kbps max. by the RS-232, and a communication time efficiency at the time of debugging has been increased.

In the Q02HCPU, Q06HCPU, Q12HCPU, and Q25HCPU, a high speed communication at a speed of 12Mbps is allowed through the USB.

26k step program transfer time

Q25HCPU(USB) 12

Q25HCPU(RS-232) 30

Q2ASHCPU 86

A2USHCPU-S1 94

010 20 30 40 50 60 70 80 90 100 (Unit:s)

(5)AnS series I/O module or special function module are available.

For Q series, if an appropriate module is not available, the AnS series I/O module or special function module can also be used for the High Performance model QCPU through the use of the QA1S65B/QA1S68B extension base unit.
