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 supplemdiffer-ented

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)
