MELSEC-Q
1 OVERVIEW
1.1 Features
High Performance model QCPU has the following new features:
(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 : 0.079

Q02HCPU, Q06HCPU, Q12HCPU, Q25HCPU : 0.034

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 : 20

MELSECNET/H link refresh processing : 4.6ms/8k word (approx. 4.3 times)

(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.

(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.
