1. Introduction

KUAX 680I, KUAX 680C and KDT 680 CT are efficient,
modularly constructed minicontrollers. They are equipped with
modules which communicate with the user program in the con­troller either directly or via transfer addresses (SLx...). KUAX
680C and KDT 680CT also have built-in inputs and outputs
which are not, however, described in this instruction manual.
There are connectors for three-conductor connections so that
proximity switches or other similar devices can be supplied via
the same cable as the signal line. Additional terminal strips are
thus made redundant. Simply plug the modules into the appro­priate slots from above:

2. Safety and Reliability

2.1. Target group

This instruction manual contains all information necessary for
the use of the described product (control device, software, etc.)
according to instructions. It is written for the personnel of the

construction, project planning, service and commissioning
departments. For proper understanding and error-free applica-

tion of technical descriptions, instructions for use and particu­larly of notes of danger and warning, extensive knowledge of
automation technology is compulsory.

2.2. Reliability

Reliability of Kuhnke controllers is brought to the highest pos­sible standards by extensive and cost-effective means in their
design and manufacture.

These include:

selecting high-quality components,
quality arrangements with our sub-suppliers,
measures for the prevention of static charge during the hand­ling of MOS circuits,
worst case dimensioning of all circuits,
inspections during various stages of fabrication,
computer aided tests of all assembly groups and their
coefficiency in the circuit,
statistic assessment of the quality of fabrication and of all re­turned goods for immediate taking of corrective action.

Safety and Reliability

Despite these measures, the occurrence of errors in electronic
control units - even if most highly improbable - must be taken
into consideration.

Safety and Reliability

2.3. Notes

Please pay particular attention to the additional notes which we
have marked by symbols in this instruction manual:

2.3.1. Danger

This symbol warns you of dangers which may cause death,
(grievous) bodily harm or material damage if the described
precautions are not taken.

2.3.2. Dangers caused by high contact voltage

This symbol warns you of dangers of death or (grievous) bodily
harm which may be caused by high contact voltage if the de­scribed precautions are not taken.

2.3.3 Important information / cross reference

This symbol draws your attention to important additional infor­mation concerning the use of the described product. It may also
indicate a cross reference to information to be found else­where.

Safety and Reliability

2.4. Safety

Our product normally becomes part of larger systems or install­ations. The following notes are intended to help integrating the
product into its environment without dangers for man or mate­rial/equipment.

2.4.1. To be observed during project planning and installation

- 24V DC power supply:
Generate as electrically safely separated low voltage. Suitable
devices are, for example, split transformers constructed to
correspond to European standard EN 60742 (corresponds to
VDE 0551)

- In case of power breakdowns or power fades: the program has
to be structured in such a way as to create a defined state at
restart that excludes dangerous states.

- Emergency switch-off installations or other emergency instal­lations have to be realized in accordance with EN 60204/
IEC 204 (VDE 0113). They must be effective at any time.

- Safety and precautions regulations for qualified applications
have to be observed.

- Please pay particular attention to the notes of warning which,
at relevant places, will make you aware of possible sources of
dangerous mistakes or failures.

- The relevent standards and VDE regulations are to be ob­served in every case.

- Control elements have to be installed in such a way as to ex­clude unintended operation.

- Control cables have to be layed in such a way as to exclude
interference (inductive or capacitive) which could influence
the operation of the controller.

To achieve a high degree of conceptual safety in the planning
and installation of electronic controllers it is essential to fol­low the instructions given in the manual exactly because wrong
handling could lead to rendering measures against dangerous
failures ineffective or to creating additional dangers.

2 - 3

Safety and Reliability

2.4.2. To be observed during maintenance and servicing

- Precaution regulation VBG 4.0 must be observed, and section
8 (Admissible deviations during working on parts) in particu­lar, when measuring or checking a controller in a power-up
condition.

- Repairs must only be made by specially trained Kuhnke staff
(usually in the main factory in Malente). Warranty expires in
every other case.

- Spare parts:
Only use parts approved of by Kuhnke. Only genuine Kuhnke
modules must be used in modular controllers.

- Modules must only be connected to or disconnected from the
controller with no voltage supplied. Otherwise they may be
destroyed or (possibly not immediately recognisably!) de­tracted from their proper functioning.

- Always deposit batteries and accumulators as hazardous
waste.

2.5. Electromagnetic compatibility

2.5.1. Definition

Electromagnetic compatibility is the ability of a device to func­tion satisfactorily in its electromagnetic environment without
itself causing any electromagnetic interference that would be
intolerable to other devices in this environment.

Of all known phenomena of electromagnetic noise, only a cer­tain range occurs at the location of a given device. This noise
depends on the exact location. It is determined in the relevant
product standards.

The international standard regulating construction and degree
of noise resistance of programmable logic controllers is IEC
1131-2 which, in Europe, has been the basis for European
standard EN 61131-2.

2.5.2. Resistance to interference

Safety and Reliability

Electrostatic discharge, ESD
in accordance with IEC 801-2, 3rd degree of sharpness

Fast transient interference, Burst
in accordance with IEC 801-4, 3rd degree of sharpness

Irradiation resistance of the device, HF
in accordance with IEC 801-3, 3rd degree of sharpness

Immunity to damped oscillations
in accordance with IEC 255-4 (1 MHz, 1 kV)

2 - 5

Safety and Reliability

2.5.3. Interference emission

Interfering emission of electromagnetic fields, HF
in accordance with EN 55011, limiting value class A, group 1

If the controller is designed for use in residential districts, then
high-frequency emissions must comply with limiting value class
B as described in EN 55011.
Fitting the controller into an earthed metal cabinet and equip­ping the supply cables with filters are appropriate means for
keeping the corresponding limiting values.

2.5.4. General notes on installation

As component parts of machines, facilities and systems, elec­tronic control systems must comply with valid rules and regula­tions, depending on the relevant field of application.

General requirements concerning the electrical equipment of
machines and aiming at the safety of these machines are con­tained in Part 1 of European standard EN 60204 (corresponds
to VDE 0113).

2 - 6

For safe installation of our control system please observe the
following notes:

Safety and Reliability

2.5.5. Protection against external electrical influences

Connect the control system to the protective earth conductor to
eliminate electromagnetic interference. Ensure practical wiring
and laying of cables.

2.5.6. Cable routing and wiring

Separate laying of power supply circuits, never together with
control current loops:

DC voltage 60 V ... 400 V
AC voltage 25 V ... 400 V

Joint laying of control current loops is allowed:

data signals, shielded
analogue signals, shielded

digital I/O lines, unshielded
DC voltages < 60 V, unshielded
AC voltages < 25 V, unshielded

2 - 7

Safety and Reliability

2.5.7. Location of installation

Make sure that there are no impediments due to temperatures,
dirt, impact, vibrations and electromagnetic interference.

Temperature

Consider heat sources such as general heating of rooms, sun­light, heat accumulation in assembly rooms or control cabinets.

Dirt

Use suitable casings to avoid possible negative influences due
to humidity, corrosive gas, liquid or conducting dust.

Impact and vibration

Consider possible influences caused by motors, compressors,
transfer routes, presses, ramming machines and vehicles.

Electromagnetic interference

Consider electromagnetic interference from various sources
near the location of installation: motors, switching devices,
switching thyristors, radio-controlled devices, welding equip­ment, arcing, switched-mode power supplies, converters / in­verters.

2.5.8. Particular sources of interference

Inductive actuators

Switching off inductances (such as from relays, contactors, so­lenoids or switching magnets) produces overvoltages. It is nec­essary to reduce these extra voltages to a minimum.
Reducing elements my be diodes, Z-diodes, varistors or RC el­ements. To provide suitably designed reducing elements, we
recommend asking the manufacturer or supplier of the corre­sponding actuators for the relevant information.

3. Modules and slots

KUAX 680I and 680C can be equipped with different types of
modules. The number of modules depends on the size of the
device:

- Devices with 4 slots: 4 modules (slots 0...3)

- Devices with 8 slots: 8 modules (slots 0...7)
(KUAX 680I only)

Modules are plugged into the top of the device. They are con­nected to the controller via the device bus plug (the figure be­low shows KUAX 680I):

Module

Memory mod­ule

Device bus plug

The following has to be observed when placing the modules:

- Only plug modules in/out in an idle state. Danger of destruc­tion!

- Sequence modules from left to right (see also "3.3. Slots").

- The modules must be screwed into the device. They could oth­erwise become loose and then cause dangerous conditions.

Modules

3.1. Design

Mounting

Labels

Status indicators

The modules are enclosed in a plastic casing. For cooling the
electronics, there are ventilation slots on the narrow edges. The
plug for the connection to the bus connector is on the bottom
side.

There is a screw sunk into the front side which is used to attach
the module to the device frame.

In KUAX 680C, KDT 680CT, and recent models of KUAX 680I
(part numbers 680.423.xx) the modules are additionally sup­ported by plastic rests. Modules made before calendar week
27/95 do not fit into these devices because they have no bores
to place the plastic rests in.

A large area on the front side is saved for a label. The label can
be used to enter the symbolic designations of the input or out­put signals (cf. symbol table under KUBES) or the function of
the module.
There is a sufficient number of labels. They are delivered to­gether with the KUAX 680I as perforated A4 tear-off blanks.
The line and column spacings are set in a way that makes an
inscription possible also for dot-matrix printers with a con­densed print.

On the lefthand side of the labels there are left as many holes
as the module provides status indicators.
These holes fit across LEDs which are built into the actual
module casing to indicate, for example, signal states of inputs
or outputs.

By definition, light emitting diodes (also referred to as LEDs)
are "Class 1 light emitting diodes (in acc. with EN 60825_1)".

Channel numbers

3 - 2

On input and output modules, the corresponding channel num­bers (0...3/7) are printed left to the LEDs. They correspond to
the inscription on the signal strip underneath the module. The
relation between terminal, LED and inscription is thus docu­mented.

3.2. Screw-type locking connectors

Screw-type locking connectors (supplied by Phoenix) are used
to connect inputs and outputs to the device:
Connector type MINI-COMBICON, 3.81 mm matrix, connect­ing diameter 0.14...1,5 mm² , max. load 8 A

The green screw-type locking connectors sit very firmly in
their position to avoid them becoming loose due to vibrations.
Should you find it difficult to pull them off with your fingers,
simply use a flat object such as a screwdriver with a wide blade
as a lever.

Never pull the wires to disconnect the plug. The wires might
otherwise slip out of the terminals or rip off even.

3.2.1. Coding

You can code the MINI-COMBICON connectors so that you do
not get them confused when putting them on (by conntecting
digital inputs to an SSI module, for example).
Push one or several coding profiles into the groove(s) provided
on the socket part of the connector for this purpose. Use a side
cutter, for example, to cut the corresponding coding element
off the plug part.

There are some connectors in the basic device which are coded
in the factory. Please refer to the corresponding illustrations to
learn where such codings exist and what they look like.

Modules

3.3. Slots

KUAX 680I can be equipped with slots for either 4 or 8 mod­ules. KUAX 680C and KDT 680CT always have 4 slots (or
none).

3.3.1. Function slots

Individual slots carry additional leads. They make the applica­tion of certain modules possible for using services provided by
the processor (counting, stepper motor control, analogue/digital
conversion...):

These specifications do not limit the application of any other

used for a slot-independent module such as a digital input or
output module.

*1) PWM stands for "pulse-width modulated output" for stepper motor control.
*2) This only concerns those analogue inputs with a resolution of 10bit that use the

A/D converter on the CPU.

3 - 4

3.4. Service modules

Modules with more complex functions need software support to
be able to carry out these functions. In order to avoid the neces­sity for the user to write these often very complicated programs
himself, so-called service modules are embedded in the pro­gram to relieve the user.
As from release 4.00, these service modules are delivered with
KUBES as individual files under the name SERV_xx.BIN. The
KUBES installation program places these files in the same sub­directory as the program files (e.g. C:\KUBESEXE).

Configuration

When configuring KUAX 680I or 680C, you enter the modules
into a list in the same order in which they will be plugged in
later. KUBES can use this information to embed the necessary
service modules in the user program and to create the reference
to the modules.

3.4.1. Transfer address ranges

Service modules use so-called transfer address ranges (max. 32
byte) for each module for data exchange with the user program.
These are directly assigned to the module slots (see table on
next page). The service module assigned to the slot during con­figuration determines the assignment of the transfer addresses.

Service modules

3.4.2. Interrupt modules

Under certain conditions, some modules trigger an interrupt in
the CPU. Like this the service module, and sometimes also the
user program, can react particularly quickly to an event. An in­terrupt caused by a module calls up an interrupt module (see ta­ble on next page). This module can contain user-defined in­structions to be carried out in case of an interrupt.

3.5. Power supply of inputs and outputs

All inputs and outputs as well as the relay for polarity safe­guarding in the digital output modules are centrally supplied
via the corresponding terminals of the basic device (see the rel­evant instruction manuals of the individual controllers).

3 - 6

3.6. Differences between KUAX 680C/KDT 680CT and KUAX 680I

All examples given in this instruction manual refer to the use
of the relevant modules in KUAX 680I.
When working with KUAX 680C or KDT 680CT you will be
obliged to take note of some differences which are caused by
the I/Os available to the basic device.

Limited applicability

- You cannot use the counter module for event counters, order
no. 680.454.03; the reason being that in its standard configu­ration, the device is already equipped with two event
counters (internal inputs).

- Stepper motor modules and internal analogue outputs share
the same system resources, i.e. the PWM outputs of the proc­essor:
PWM analogue output stepper motor module
1 AO00.00 680.444.01 and .02
2 AO00.01 680.444.02
Thus, if you are using a two-channel stepper motor module
(680.440.02) neither of the two internal analogue outputs can
be used. If you are working with a single-channel stepper
motor module (680.440.01), you still have the option of us­ing internal analogue output AO00.01 at least.

Addressing

Please note that input and output groups are occupied already
by the internal I/Os. While plugged-in modules are numbered
in groups from left to right just like in KUAX 680I, they start
with different group numbers:
Modules first group
digital inputs I02
analogue inputs AI01
digital outputs O02
analogue outputs AO01

For further information please refer to the device manuals.

3 - 7

Modules

3 - 8

4. Digital inputs and outputs

Digital inputs and outputs are used for leading digital signals (1
or 0, High or Low, On or Off etc.) from the machine or system
into the controller (inputs) or vice versa (outputs).

These include:

Digital input signals from

- switches

- key-switches

- sensors

- etc.

Digital output signals for switching

- relays

- contactors

- magnetic valves

- etc.

There are only 2 possible states of digital signals:

- logical 0 (Low, Off...)

- logical 1 (High, On...)

These two signal states form the basis for most of the functions
of control engineering.

There are several digital input and output modules available for
adjusting the controller to the different types of signals.

4 - 1

Digital inputs and outputs

4.1. Plugging digital input and output modules

As from monitor version 4.10 (KUBES version 4.01), KUAX
680I can also be equipped with 16pin modules. KUAX 680C as
from its first delivered machines.

All earlier versions of KUAX 680I only allow application of
8pin modules.

Digital input and output modules can be plugged into any slot
as long as this slot is not needed for another module (see
"3.3.1. Function slots"). Certain regulations must be regarded,
however:

4.1.1. Addressing (input/output groups and channels)

Upon switching the controller on, inputs and outputs of all
plugged-in modules are automatically numbered from left to

right in groups of 8 channels (.00... .07) each. Thus, the first in-

put group is assigned the group number I00, the second one is
assigned I01 etc. The output groups are treated in the same way
by the system: O00, O01 etc.

Example for KUAX 680I:

012 3

Legend:

4 - 2

0 input module, 8pin I00
1 output module, 8pin O00
2 input module, 16pin I01, I02
3 input/output module, 8/8pin I03, O01

Groups

Inputs: I00...max. I15 (on 16pin modules)
Ouputs: O00...max. O07

In KUAX 680C, the first two input groups, I00 and I01, and the
first two output groups, O00 and O01, are allocated already to
the internal inputs and outputs. The modules for inputs and
outputs thus start with numbers I02 and O02.

Channels

Each group consists of 8 channels, i.e. inputs or outputs:
Inputs: Ixx.00...Ixx.07
Outputs: Oxx.00...Oxx.07

4.1.2. Reserved slots

Reserved slots for a module type of which there are modules
plugged in already (e.g. input modules) must always be located
after the last plugged-in module of the same type. Otherwise,
the module numbering (addressing) of the following modules
of the same type will change.

Addressing

Example: I I _ O

Reserved slot for an input module (I02.)

Reserved slots for later plugging of function modules or ana­logue input modules may also be located between modules of
one type.

Example: I _ I O

4.2. Digital input modules

Digital input modules are used for reading the signal states of
switches, key switches, relay contacts etc. When working with
proximity switches and semi-conductor sensors please make
sure to keep them running within the switching thresholds
given below.

Switching thresholds and filters

The input line is used to adjust the connected signals to the sys­tem voltage.

These are the same inputs as described in chapter “4.2.1. Input
module, 24 V DC, 8 inputs” (see there for picture and connec­tions).
Added is the function of the real-time clock which is realised
on this module.

4.2.2.1. Real-time clock

A clock module is integrated in the module which is supplied
by an accu in case of a voltage cut.
A KUBES module is available for setting and evaluating time
and date.

Name: CLOCK

Call from within the program:

JPK CLOCK

<actual time> <status indication>
<set>

The module should be called up in every PLC cycle. The pro­gram within the module is organized so as to updating the input
parameter “actual time” every second.
If there is a set command (first byte in data field “set” = 255),
the preset values are taken over immediately.
Output byte “status indication” reports any occurring errors.

Digital inputs and outputs

4.2.2.2. Parameters of KUBES module “CLOCK”

The user has to reserve two data fields for the clock parameters
and one byte for status indication. It is helpful to enter these
operands into the symbol table (KUBES) at the beginning of
project planning.

The data fields must consist of subsequent operand ranges.
When programming the KUBES module, the first address of
each data field is entered.

We recommend to take over the symbols as shown in the 3 fol­lowing tables:

Digital inputs and outputs

4.2.4. Input module, 24 V DC, 8 inputs, 1 ms

These are basically the same inputs as described earlier in
chapter "4.2.1. Input module, 24 V DC, 8 inputs" (see there for
diagram and connectors).
The difference between the two modules is in the much re­duced signal delay time of the module described in this chap­ter. This shorter signal delay makes it possible to register very
much increased signal sequences (e.g. fast counting impulses).

Please take into consideration that the shorter signal delay
time may lead to situations where noise pulses are not filtered
out and are therefore not registered by the CPU. We therefore
strongly recommend the use of shielded wires.

Signal delay:

In order to avoid voltage surges (noise pulses) being recog­nized as valid signals, thus executing wrong switching opera­tions, they are filtered out.

Signal identification is thus delayed by nominally 1 ms:

U[V]

24

Raising delay*):

tve= 0.3 ... 1.0ms

Falling delay*):

15

tva= 0.4 ... 1.4ms

Signal

*) The input signals are read between the individual program cycles and then written into the process

4.2.5. Input module, 24 V DC, 16 inputs, 1 ms

These are basically the same inputs as described earlier in
chapter "4.2.3. Input module, 24 V DC, 16 inputs" (see there
for diagram and connectors).
The difference between the two modules is in the much re­duced signal delay time of the module described in this chap­ter. This shorter signal delay makes it possible to register very
much increased signal sequences (e.g. fast counting impulses).

Please take into consideration that the shorter signal delay
time may lead to situations where noise pulses are not filtered
out and are therefore not registered by the CPU. We therefore
strongly recommend the use of shielded wires.

Signal delay:

In order to avoid voltage surges (noise pulses) being recog­nized as valid signals, thus executing wrong switching opera­tions, they are filtered out.

Signal identification is thus delayed by nominally 1 ms:

These are basically the same inputs as described earlier in

The difference between the two modules is in the extended
functionality of the module described in this chapter concern­ing the registeration of fast input signals.

time may lead to situations where noise pulses are not filtered

4.2.6.2. Interrupt inputs

Inputs Ixx.00...03 (lower group, terminal underneath the mod­ule) support interrupt functions and have a particularly short
signal delay time of nominally 0.3 ms.
For enabling and registering interrupts, each module is auto­matically assigned a transfer address range (see "3.4. Service
modules") and an interrupt module for interrupt evaluation.

Transfer address ranges and interrupt modules

Slot Transfer address range Interrupt module

0 SLA00.00...01.15 1
1 SLC00.00...01.15 3
2 SLE00.00...01.15 5
3 SLG00.00...01.15 7
4 SLI00.00...01.15 9
5 SLK00.00...01.15 11
6 SLM00.00...01.15 13
7 SLO00.00...01.15 15

When enabled, each of the 4 inputs can trigger an interrupt in
the CPU by raising or falling signal edges. In this case, the
CPU immediately interrupts the normal program run and calls
up the interrupt module that is assigned to this module slot. In
this interrupt module you can get the information about the sig­nal that triggered the interrupt and also start the necessary
measures. We recommend keeping the program in the interrupt
module as short as possible to avoid putting great loads on the
cycle time, especially if interrupts are used frequently.

4 - 20

The user program can also scan the status of the interrupt in­puts via the normal input addresses, Ixx.00...03. This means
working with the signal delay that is extended by the cycle
time, however.

The functions of the transfer addresses are listed in the table on

Digital inputs and outputs

Interrupt frequency

Every interrupt lengthens the cycle time. If an overall program
cycle is longer than 70 ms, the monitor will trigger a watchdog
and interrupt the program run. Thus the interrupt frequency
must not exceed a maximum of 2.5 kHz for short periods of
time (approx. 10 ms). Taken over longer periods of time, the
maximum interrupt frequency must be no higher than 1 kHz. If
you are using the interrupt module as a counter you must make
sure not to exceed the interrupt frequency of 1 kHz.

Function

Output modules provide the connection to external actuators
(relays, contactors, magnets, valves...).
Resistive and inductive loads can be connected. Freewheeling
diodes have been added to suppress inductive disable surges.
The switching state of the outputs is indicated by LEDs.

Signal line connection

The controller generates output signals of a voltage of 24 V
DC. These are picked up at the plug-screw terminals on the sig­nal strip. Each module is assigned one block of 8 of these ter­minals. The block is placed directly underneath the module slot
(see diagram above).

Polarity safeguard

If the connection is correct, a relay in the module switches the
supply of the outputs. A destruction of the module in case of
reversed polarity is thus avoided.

Increased performance by parallel connection

The load-carrying ability of the individual outputs is limited
(see Technical specifications). It is permissible, however, to
connect 2 outputs in parallel, thus redoubling the performance.

You must only connect outputs on the same module in parallel.

Protection against short circuit and overload

The outputs are protected against destruction by overload or
short circuit:

- the load current is limited to approx. 1.0...1.2 A

- a temperature monitor switches the output off after 0.1 to1 s
and reports a short circuit to the CPU

in KUAX 680I and 680C:

- the CPU outputs a short circuit message,

- reports short circuit by flash pulse (1) on "failure" LED,

- activates interrupt module no. 18,

- see also instruction manual KUAX 680I, E 308 GB, Appen­dix D.1.

in KUAX 680S:

- the CPU disables all outputs,

- reports a short circuit by flash pulse (1) on "status" LED,

- sends event notification (1) to the master via PROFIBUS

after removing the error:

- reset device (by switching it off and on)

Restart

- Search source of error

- Put controller into idle condition

- Remove error

- Supply controller with voltage

Digital inputs and outputs

Backfeeding of outputs

Backfeeding means that an output is externally supplied with
voltage. This is no problem normally.
However, under certain circumstances it can destroy the free­wheeling diode of the relevant output:
if

- the controller is on

- and outputs are switched on and under a load

- and if the module supply (upper terminal) is off

then

- the backfed output will use the built-in free-wheeling diode

for supply

- and the load the current may destroy the free-wheeling diode.

5. Analogue inputs and outputs

Analogue inputs and outputs are used to lead analogue (i.e. per­manently changeable) signals from the machine or the system
into the controller (inputs) or vice versa (outputs).

These include:

Analogue signals such as

- temperature values

- liquid levels

- rotational speeds

- etc.

There is a great number of analogue modules available for the
different applications. These are described on the following
pages.

5 - 1

Analogue inputs and outputs

5.1. Plugging analogue input and output modules

When switching the controller on, all plugged-in modules are
numbered automatically from left to right. Thus the first ana­logue input module is assigned the group number AI00, the
second one becomes AI01 etc. (analogue outputs: AO00.00...).
Analogue input modules with a resolution of 10 bit must only
be plugged into certain slots (see “3.3.1. Function slots”) as
they use the analogue/digital converter on the processor.
All other analogue modules can be plugged into any slot.

5.1.1. Addressing (anal. input/output groups and channels)

Upon switching on KUAX 680I, inputs and outputs of all
plugged-in modules are automatically numbered from left to

right in groups of a maximum of 4 channels (.00... .03) each.

Thus, the first analogue input group is assigned group number
AI00, the second one becomes AI01 etc. (for exceptions see ch.
"3.6. Differences between KUAX 680C/KDT 680CT...") The
analogue output groups are treated in the same way by the sys­tem: AO00, AO01 etc.

123 4

Example for KUAX 680I:

Legend:

1 analogue output module, 4pin AO00
2 analogue output module, 4pin AO01
3 analogue input/output module, 2/2pin AI00, AO02

5 - 2

4 analogue input module, 4pin AI01

Groups

Inputs: AI00...max. AI07
Outputs: AO00...max. AO07

In KUAX 680C and KDT 680CT, the first input group, AI00,
and the first output group, AO00, are allocated to the internal
inputs and outputs. The modules for inputs and outputs thus
start with number AI01 and AO01 resp.

Channels

Each group consists of a maximum of 4 channels, i.e. inputs or
outputs:
Inputs: AIxx.00...AIxx.03
Outputs: AOxx.00...AOxx.03

5.1.2. Reserved slots

Reserved slots for a module type of which there are modules
plugged in already (e.g. input modules) must always be located
after the last plugged-in module of the same type. Otherwise,
the module numbering (addressing) of the following modules
of the same type will change.

Plugging analogue modules

Example: AI AI _ AO

Reserved slot (e.g. for an
analogue input module)

Reserved slots for later plugging of function modules or ana­logue input modules may also be located between modules of
one type.

Both leads, signal and Gndn, must definitely be connected for
each channel (0...3). The Gndn-connections are not identical
with the device-Gnd.

Shielding

Shielded cables have to be used for connecting the analogue
signals. The shielding is connected to the aluminium
baseprofile of the controller by M3 screws (under certain cir­cumstances, the additional grounding of the other end of the
cable may be commendable).

5.2.1.3. Representation of the analogue value

5.2.3.4. Evaluation in the user program

There are two ways of evaluating the input information in the
user program:

As temperature value in steps of 1/10 °C
(0...3000 0...300.0 °C)

The temperature is represented as 12bit value (in 2 bytes) in the
transfer addresses (see table on previous page).
In the user program, the temperature value is read in a double­byte operation.

Example: LD SLE00.00 ;temperature value channel 0

CMPD>= 1500 ;greater/equal 150 °C ?
= M00.01 ;set marker if so

As analogue value in a 10bit resolution

The resolution corresponds to the Kuhnke standard for ana­logue inputs. The temperature is represented in the 16 bit ana­logue input addresses (AI...). The addressing corresponds to the
sequence of the plugged-in analogue input modules (see "5.1.
Plugging analogue input and output modules").
In this address the value is in bits 5...14. Bits 0...4 and 15 (sign
bit) always have the status 0:

Address bit 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0

Status 0 ------------ value read ----------- 0 0 0 0 0

In the user program, the value is read in a double-byte opera­tion. Scales 0...10.00V or 0...20.00mA can be used as refer­ence.

Example: LD AI00.00 ;analogue value channel 0

address as a two's complement representation. In the address,
the value is in bits 7...14. Bits 0...6 are not evaluated, bit 15
(sign bit) always has the status 0:

Address bit: 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0

Status: 0 -------output value------- x x x x x x x

5 - 32

Analogue output modules

In the user program, the value is entered in a double-byte oper­ation.

Example: LD 10 mA ;input range 0(4)...20 mA

=D AO00.00

Depending on the setting of the corresponding transfer address
(see below), the input value is defined as 0...20 or 4...20mA
value.

5.3.2.4. Transfer address ranges

Each module is assigned a transfer address range of 32 byte
(see also "3.4. Service modules"). The first group of this range
is used by the analogue output module to determine the range
of the output signal.
The address range depends on the slot:

Slot Transfer address range

0 SLA00.00...01.15
1 SLC00.00...01.15
2 SLE00.00...01.15

5.4. Analogue input/output modules

These modules have analogue inputs and analogue outputs.
They are mainly used in cases where only a small amount of
channels is required.

5.4.1. Analogue I/O module, 2 I 0...10 V, 2 O 0...±10V

Analogue inputs and outputs

5.4.1.1. Slots

Analogue inputs

This module uses the analogue-to-digital converter of the proc­essor on the CPU for the analogue inputs. For this purpose, cer­tain slots carry additional leads. If the analogue inputs are used,
then the module can only be operated on these slots (see "3.3.
Slots”):

Slot no. Useable channels

4

As there are only 2 analogue inputs the module should prefer­ably be plugged into slot 2 as long as this is not occupied al­ready.

Analogue outputs

The digital-to-analogue converter can convert 12bit digital val­ues (including signs).
If only the analogue outputs of the module are to be used, then
the module can also be plugged into any other slot.

5.4.1.2. Connectors

Analogue inputs

The connections of the signal lines for the analogue inputs are
on the 8-pin plug-screw connector underneath the module:

Both leads, signal and Gndn, must definitely be connected for
each channel. The Gndn-connections are not identical with the
device-Gnd.

The connections of the signal lines for the analogue outputs are
on the side of the module. A 4-pin plug-screw connector (5.08
mm grid) is used, which is delivered together with the module.

Signal (0)
Gnd (0)
Signal (1)
Gnd (1)

Shielded cables have to be used for connecting the analogue
signals. The shielding is connected to the aluminium
baseprofile of the controller by M3 screws (under certain cir­cumstances, the additional grounding of the other end of the
cable may be commmendable).

5.4.1.3. Representation of the analogue value

Analogue inputs

The read analogue value is digitalized and then written into a
16bit address as a two’s complement representation. In this ad­dress, the value is in bits 5...14. Bits 0...4 and 15 (sign bit) al­ways have the status 0:

Address bit 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0

Status 0 ------------ value read ----------- 0 0 0 0 0

In the user program, the value is read in a double-byte opera­tion.

Example: LD AI00.00

CMPD< 5.5V ;input range 0...10.00V
= M00.01

Analogue outputs

The analogue value to be output must be written into a 16bit
address as a two’s complement representation by the user pro­gram. In this address, the value is in bits 4...14 and the sign in
bit 15. Bits 0...3 are not evaluated.

Address bit 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0

Status ± ------------ output value ------------- x x x x

In the user program, the value is written in a double-byte oper­ation.

Example: LD 5.5V ;input range 0...±10.00V

=D AO00.00
