Programmable Logic Controllers • QnA Series Overview
The QnA CPU Line
The QnA CPU line was developed to reduce development time by offering
an innovative multiple program/multiple user CPU environment. This allows

development to be split between multiple programmers for concurrent devel-
opment, slashing time to market/project schedules. Additionally,
systems can be divided into modular programs, each representing
different machine functions to simplify troubleshooting, reduce downtime
and promote code re-use to shorten future development.
The QnA CPU also offers a high performance platform with unparalleled
networking capability. All QnA CPUs are fully compatible with A Series I/O.
For networking and communications use QnA type modules.

Programmable Logic Controllers • Q4AR Series Overview
The Redundant Q4AR System Description
The Q4AR CPU gives you redundant system architecture with outstanding
availability for critical processes requiring maximum protection against fail-
ures. In normal operation the control program is executed by the active
CPU; the standby CPU remains essentially idle, just copying the process
data. In the event of an abnormal operating status or failure of the active
VCPU the standby CPU cuts in immediately and takes over control, starting
with the status of the last set of process data copied. To ensure maximum
availability the redundant Q4AR system is installed on an A32RB/A33RB
base unit with the following components:
2 power supply units
2 Q4AR CPUs
2 system control modules
1 bus switching module for connection of the extension base unit
It is also possible to install communications modules for connection to the
redundant NET/10 network in one or two slots on the base unit.

The Process Control System
The AS92R system control modules handle the automatic activation of the
standby CPU, monitoring all the following system functions:
Self-diagnostics of the Q4AR CPU
Q4AR CPU watchdog
AS92R watchdog
5 VDC power supply
24 VDC power supply
Power supply unit errors
When the control is passed to the standby CPU the AS92R system control
module also activates an alarm output. The switchover to the standby CPU
is handled smoothly and under full control, using a process image of the
active CPU (up to 48K words) that is continuously copied by the standby
CPU during normal operation. In the event of a failure the standby CPU cuts
in, using the last process image stored before the error occurred (see dia-
gram at right), guaranteeing smooth continuation of process control.You
can also manually switch the control to either CPU for servicing work with
the key-operated switch on the A6RAF bus switching module. The Q4AR
features an integrated arithmetic coprocessor, which enables it to perform
floating-point math between 10 and 100 times faster than the A3U CPU.
The instruction set of the Q4AR CPU also includes 47 dedicated process
control instructions.

Programmable Logic Controllers • A Series Overview
A Series Overview
The CPU and the modules are held in a base unit which has an
internal bus connection for communication between the individual
modules and the CPU. The power supply module which supplies
the voltage for the entire system is also installed on this base unit.
The main base units are available in different versions with a differ-

ent number of module slots. Each base unit can be supplemented
by means of an extension base unit, providing additional slots.
Besides the common base units also redundant systems for
2 CPUs or 2 power supply modules are available. (Q4AR
systems only)
If you wish to keep open the option of subsequent extension of
your PLC or if you have free slots on your main base units, you
can insert dummy modules here. They serve to protect the free
slots from soiling or from mechanical effects but can also be used
for reserving I/O points.
For cabling larger systems and machines—e.g. in a modular
design—the use of remote I/O modules offers additional
communications facilities. These modules are connected by
means of a variety of networking options.
Extension
The main base unit and the extension base units are simply
connected to one another by extension cables. These connecting
cables also supply the extension base units with the operating
voltage of 5 VDC.
Up to seven extension base units can be connected to a main
base unit, over a distance of 6.6m
When choosing the power supply module, the total power
consumption of the I/O modules, of the special function modules,
and of the peripherals must be taken into account. Also the
voltage drop in the connecting cable has to be regarded. If nec-
essary, an extension base with a further power supply module
should be used. (A6xB extension bases)

Memory cassettes are available for permanent program storage. The cassettes contain CMOS RAM
memory chips with a variety of capacities. The memory can be used for storing PLC programs, parame-

ter data, comments and operands. The contents of the cassettes’ memory is protected by an integrated
lithium battery. Two sockets are provided for the installation of EPROM memory chips. Unused memory
in the cassettes can be used as an additional data area (the SWO-FN1 software is necessary for doing
this with the AnN CPUs).

The main base unit accommodates and connects the CPU and the power
supply, input, output and special function modules.
Special Features:
■ Module addressing is automatic, with an eight-slot base unit assumed
as the default. Empty or nonexistent slots (i.e. in units with fewer than 8

slots) are automatically assigned 16 addresses. You can change the
automatic address allocation with GX Developer.
■ DIN rail or bolt mounting.
■ Modules slot into place and are held with a retaining screw.
■ Use with A and QnA CPUs.
The extension base units are connected to the main base unit with extension
cables, enabling configuration of an A series system with up to 64 I/O
modules. You can choose from extension base units with or without a slot
for power supply modules.
Special Features:
■ You can connect a maximum of seven extension base units to each main
base unit.
■ The maximum distance between the first and the last base unit is 6.6 m.
■ Use with A and QnA CPUs.
Extension base units with a power supply module are required in the
following circumstances:
■ When the total power consumption of the installed modules exceeds the
capacity of the power supply module on the main base unit.
■ When the supply voltage falls to below 4.75 V as a result of the voltage
drop along the main to the extension base unit path.
