Before commencing the installation

• Disconnect the power supply of the device.

• Ensure that devices cannot be accidentally
restarted.

• Verify isolation from the supply.

• Earth and short circuit.

• Cover or enclose neighbouring units that
are live.

• Follow the engineering instructions (AWA)
of the device concerned.

• Only suitably qualified personnel in
accordance with EN 50110-1/-2
(VDE 0105 Part 100) may work on this
device/system.

• Before installation and before touching
the device ensure that you are free of
electrostatic charge.

• The functional earth (FE) must be
connected to the protective earth (PE) or
to the potential equalisation. The system
installer is responsible for implementing
this connection.

• Connecting cables and signal lines should
be installed so that inductive or capacitive
interference does not impair the
automation functions.

• Install automation devices and related
operating elements in such a way that they
are well protected against unintentional
operation.

• Suitable safety hardware and software
measures should be implemented for the
I/O interface so that a line or wire breakage
on the signal side does not result in
undefined states in the automation
devices.

• Ensure a reliable electrical isolation of the
low voltage for the 24 volt supply. Only
use power supply units complying with
IEC 60364-4-41 (VDE 0100 Part 410) or
HD 384.4.41 S2.

• Deviations of the mains voltage from the
rated value must not exceed the tolerance
limits given in the specifications, otherwise
this may cause malfunction and dangerous
operation.

•Emergency stop devices complying with
IEC/EN 60204-1 must be effective in all
operating modes of the automation
devices. Unlatching the emergency-stop
devices must not cause restart.

• Devices that are designed for mounting in
housings or control cabinets must only be
operated and controlled after they have
been installed with the housing closed.
Desktop or portable units must only be
operated and controlled in enclosed
housings.

II

• Measures should be taken to ensure the
proper restart of programs interrupted
after a voltage dip or failure. This should
not cause dangerous operating states even
for a short time. If necessary, emergency­stop devices should be implemented.

• Wherever faults in the automation system
may cause damage to persons or property,
external measures must be implemented to
ensure a safe operating state in the event
of a fault or malfunction (for example, by
means of separate limit switches,
mechanical interlocks etc.).

Target readership easy must only be installed and connected up by trained

electricians or other persons who are familiar with the
installation of electrical equipment.

Specialist electrical training is needed for commissioning and
creating circuit diagrams. When active components such as
motors or pressure cylinders are controlled, parts of the
system can be damaged and persons put at risk if easy is
connected or programmed incorrectly.

Proper use easy is a programmable switching and control device and is

used as a replacement for relay and contactor control
circuits. easy may only be operated when it has been
correctly and properly installed.

• easy is designed to be installed in an enclosure, switch
cabinet or service distribution board. Both the power feed
and the signal terminals must be laid and covered so as to
prevent accidental contact.

• The installation must comply with regulations for
electromagnetic compatibility (EMC).

• The starting up of easy should not cause any hazards
arising from controlled devices, such as unexpected motor
startups or power ups.

Improper use

easy should not be used as a substitute for safety-related
controls such as burner or crane controls, emergency-stop or
two-hand safety controls.

easy is an electronic control relay with logic functions, timer,
counter and time switch functions. It is also a control and
input device in one that can perform many different tasks in
domestic applications as well as in machine building and
plant construction.

Circuit diagrams are connected up using ladder diagrams,
and each element is entered directly via the easy display. For
example, you can:

• Connect make and break contacts in series and in parallel

• Connect output relays and markers,

• Use outputs as relays, impulse relays or latching relays

• Use multi-function timing relays with different functions

• Use up and down counters,

• Count high-speed counter pulses

• Measure frequencies

• Process analog inputs, easy-AB, easy-DA, easy-DC,
(EASY512..: two analog inputs, easy700: four analog
inputs)

• Display any texts with variables, enter setpoints

• Use year time switches, 7-day time switches,
EASY…-..-.C(X),

• Count operating hours (four retentive operating hours
counters integrated)

• Track the flow of current in the circuit diagram

• Load, save and password-protect circuit diagrams

Applies to easy-AC devices with a power supply
greater than 24 V AC:

• The voltage terminals for phase L and neutral conductor
N have been reversed.

• This enables the easy interface (for memory card or PC
connection) to have the full connection voltage of the
phase conductor (100 to 240 V AC).

• There is a danger of electric shock if the connection at
the easy interface is not properly connected or if
conductive objects are inserted into the socket.

For longer lengths connect in series a diode (e.g. 1N4007)
for 1 A, min. 1000 V reverse voltage, to the easy input.
Ensure that the diode is pointing towards the input as shown
in the circuit diagram, otherwise easy will not detect the
1 state.

easy-AC:
Inputs I7 and I8 have a higher input current on the easy-AC.
Neon bulbs with a maximum residual current of 2 mA/1 mA
at 230 V/115 V can be connected to I7 and I8.

Two-wire proximity switches have a residual current with the
“0” state. If this residual current is too high, the easy input
may only detect a “1” signal.

Therefore, use inputs I7 and I8. An additional input circuit is
required if more inputs are used.

Connecting easy DC analog inputs

The easy-AB, easy-DA and easy-DC basic units are provided
with analog inputs. Inputs I7 and I8, and if present I11 and
I12, can be used to connect analog voltages ranging from
0 V to 10 V. A simple additional circuit also allows the
analog evaluation of currents from 0 to 20 mA. The analog
input signals are converted to 10-bit digital signals.

The following applies:

• 0 V DC corresponds to a digital 0.

• 5 V DC corresponds to a digital value of 512.

• 10 V DC corresponds to a digital value of 1023.

Safety measures with analog signals

X Use shielded twisted pair cables to prevent interference

with the analog signals.

X For short cable lengths, ground the shield at both ends

using a large contact area. If the cable length exceeds
30 m or so, grounding at both ends can result in
equalisation currents between the two grounding points
and thus in the interference of analog signals. In this case,
only ground the cable at one end.

X Do not lay signal lines parallel to power cables.
X Connect inductive loads to be switched via the easy

outputs to a separate power feed, or use a suppressor
circuit for motors and valves. If loads such as motors,
solenoid valves or contactors are operated with easy via
the same power feed, switching may result in interference
on the analog input signals.

The following four circuits contain examples of applications
for analog value processing.

i

Caution!

Analog signals are more sensitive to interference than
digital signals. Consequently, greater care must be taken
when laying and connecting the signal lines.

Incorrect switching states may occur if they are not
connected correctly.

i

Caution!

Ensure that the reference potential is connected. Connect
the 0 V of the power supply unit for the different setpoint
potentiometers and sensors shown in the examples to the
0 V and neutral conductor terminal (easy-AB) of the easy
power feed. Otherwise incorrect switching states may
occur if they are not connected correctly.

05/04 AWB2528-1508GB

Power supply of easy-AB devices and analog inputs

With easy-AB devices that process analog signals, the device
must be fed via a transformer so that the device is isolated
from the mains supply. The neutral conductor and the
reference potential of the DC power feed of analog sensors
must be electrically connected.

Figure 20: easy-AB analog input, connection of reference

potentials

Ensure that the common reference potential is grounded
or monitored by a ground fault monitoring device. Observe
the requirements of the relevant regulations.

Caution!

Please note the following when switching off inductive
loads.

Suppressed inductive loads cause less interference in the
entire electrical system. For optimum suppression the
suppressor circuits are best connected directly to the
inductive load.

Installation

58

05/04 AWB2528-1508GB

If inductive loads are not suppressed, the following applies:
Several inductive loads should not be switched off
simultaneously to avoid overheating the driver blocks in the
worst possible case. If in the event of an emergency stop the
+24 V DC power supply is to be switched off by means of a
contact, and if this would mean switching off more than one
controlled output with an inductive load, then you must
provide suppressor circuits for these loads (see the following
diagrams).

Figure 34: Inductive load with suppressor circuit

Behaviour with short-circuit/overload

Should a short circuit or overload occur on a transistor
output, this output will switch off. The output will switch on
up to maximum temperature after the cooling time has
elapsed. This time depends on the ambient temperature and
the current involved. If the fault condition persists, the
output will keep switching off and on until the fault is
corrected or until the power supply is switched off
(a section “Monitoring of short-circuit/overload with
EASY..-D.-T..”, page 242).

Connecting bus systems The EASY-LINK connection is designed to allow bus

connections, apart from I/O expansions. Special bus
connection devices are available for the bus systems in use.

At present, easy700 can communicate with the following
bus systems or networks:

• AS-Interface (Actuator-Sensor Interface)

•Profibus-DP

•CANopen

• DeviceNET

The different bus systems offer different functions.

The following applies:

• As a minimum data exchange, the input data R1 to R16
and output data S1 to S8 can be exchanged, provided that
the bus system supports this.

• If the bus system or bus gateway is capable of this,
function block, date, time parameters can be read and
written via the bus. The states of inputs, outputs, markers
can be read.

h

Only one device (expansion device or bus connection) can
be connected to the EASY-LINK connection.

Creating your first circuit
diagram

The following small circuit diagram takes you step by step
through wiring up your first easy circuit diagram. In this way
you will learn all the rules, quickly enabling you to use easy
for your own projects.

As with conventional wiring, you use contacts and relays in
the easy circuit diagram. With easy, however, you no longer
have to connect up components individually. At the push of
a few buttons, the easy circuit diagram produces all the
wiring. All you have to do is then connect any switches,
sensors, lamps or contactors you wish to use.

Circuit diagram

The circuit diagram is that part of the program where the
contacts are connected together. In RUN mode a coil is
switched on and off in accordance with the current flow and
the coil function specified.

Function relays

Function relays are program elements with special functions.
Example: timing relays, time switches, counters. Function
relays are elements provided with or without contacts and
coils as required. In RUN mode the function relays are
processed according to the circuit diagram and the results
are updated accordingly.

Examples:
Timing relay = function relay with contacts and coils
Time switch = function relay with contacts

Relay

Relays are switching devices which are electronically
simulated in easy. They actuate their contacts according to
their designated function. A relay consists of at least a coil
and a contact.

Contacts

You modify the current flow with the contacts in the easy
circuit diagram. Contacts such as make contacts carry a 1
signal when closed and 0 when open. Every contact in the
easy circuit diagram can be defined as either a make contact
or a break contact.

78

05/04 AWB2528-1508GB

Coils

Coils are the actuating mechanisms of relays. In RUN mode,
the results of the wiring are sent to the coils, which switch
on or off accordingly. Coils can have seven different coil
functions.

easy works with different contacts, which can be used in any
order in the contact fields of the circuit diagram.

To ensure compatibility with easy400 and easy600
devices, each easy500 and easy700 is provided logically
with all possible contacts. If contacts are not supported by
the device, i.e. devices without a clock, their switching
state is always zero. The contacts (make contact) of the
time switches are always set to logic 0.

The advantage of this process is that you can use the same
circuit diagram on all easy500, easy700, easy-AB, easy­AC, easy-DA and easy-DC devices.

devices, each easy500 and easy700 is provided logically
with all relay types. If a relay type is not supported by the
device, i.e. devices without a clock, their switching state is
always zero. The contacts (make contact) of the time
switches are always set to logic 0.

The advantage of this process is that you can use the same
circuit diagram on all easy500, easy700, easy-AB, easy­AC, easy-DA and easy-DC devices. Furthermore, you can
use outputs that are not physically present as markers.

The coil functions and parameters are listed with the
description of each function relay.

Circuit diagram display

In the easy circuit diagram, contacts and coils are connected
up from left to right - from the contact to the coil. The circuit
diagram is created on a hidden wiring grid containing
contact fields, coil fields and rungs. It is then wired up with
connections.

• You can add switch contacts in the three contact fields.
Easy adds the first energized contact field automatically.

• You add the relay coil to be controlled together with its
function and designation in the coil field.

• Every line in the circuit diagram forms a rung. Up to 128
rungs can be wired in a circuit diagram.

• Connections are used to produce the electrical contact
between switch contacts and the coils. They can be
created across several rungs. Each point of intersection is
a connection.

Saving and loading circuit diagrams

There are two ways of saving circuit diagrams in easy
externally:

• By saving to a memory card

• By saving to a PC running EASY-SOFT-BASIC.

Once they have been saved, programs can be reloaded into
easy, edited and run.

All circuit diagram data is saved in easy. In the event of a
power failure the data will be retained until the next time it
is overwritten or deleted.

Memory card

Each EASY-M-32K memory card contains a circuit diagram
which is inserted into the easy interface. The program is
stored retentively on the memory card.

The way the memory card works and a description of how to
transfer a program to the card is given in section “Memory
card” on page 248.

EASY-SOFT-BASIC

EASY-SOFT-BASIC is a PC program with which you can
create, store, test (simulate) and manage easy circuit
diagrams.

h

The circuit diagram display performs two functions:

• In STOP mode it is used to edit the circuit diagram.

• In RUN mode it is used to check the circuit diagram
using the Power flow display.

EASY-M-8K memory cards of easy400 devices can be read
in easy500. EASY-M-8K memory cards of easy400 devices
and easy600 EASY-M16K memory cards can be read in
easy700.

Write operations from easy500 and easy700 are only
possible to the EASY-M32K memory card.

Completed circuit diagrams are transferred between your PC
and easy via the connecting cable. Once you have
transferred a circuit diagram, simply run easy straight from
your PC.

Details on the program and transferring circuit diagrams are
given in section “EASY-SOFT-BASIC” from page 252.

Working with contacts
and relays

In easy circuit diagrams, the switches, buttons and relays of
conventional circuit diagrams are connected up using input
contacts and relay coils.

Input and output contacts

First specify which input and output terminals you wish to
use in your circuit.

Depending on the type and configuration, easy has 8, 12 or
24 input terminals and 4, 6, 8, 10 or 16 outputs. The signal
states on the input terminals are detected in the circuit
diagram with the input contacts I1 to I12. R1 to R12 are the

Switching with the cursor buttons

With easy, you can also use the four cursor buttons as hard­wired inputs in the circuit diagram.

The buttons are wired in the circuit diagram as contacts P1
to P4. The P buttons can be activated and deactivated in the
System menu.

The P buttons can also be used for testing circuits or manual
operation. These button functions are also useful for
servicing and commissioning purposes.

Example 1:

A lamp at output relay Q1 is switched on and off via inputs
I1 and I2 or using cursor buttons

Í Ú.

Example 2

Terminal I1 is used to control output relay Q1. Terminal I5
switches to Cursor button mode and deactivates rung I1 via

M

easy contains a built-in measuring device enabling you to
monitor the switching states of contacts and relay coils
during operation.

X Complete the small parallel connection and switch easy to

RUN mode via the main menu.

X Return to the circuit diagram display.

You are now unable to edit the circuit diagram.

The circuit diagram display performs two functions
depending on the mode:

• STOP: Creation of the circuit diagram

• RUN: Power flow display

X Switch on I3.

In the power flow display, energized connections are thicker
than non-energized connections.

You can follow energized connections across all rungs by
scrolling the display up and down.

Coil functions

You can set the coil function to determine the switching
behaviour of relay coils. The following coil functions are
available for relays Q, M, S, D, “:”:

Table 8: Coil function

Marker relays M and N are used as a flag. The S relay can be
used as the output of an expansion unit or as a marker if no
expansion unit is connected. The only difference between
them and the output relay Q is that they have no output
terminals.

Rules for wiring relay coils

To ensure a clear overview of all relay states only assign the
same coil function once to a relay (

ä, S, R). However,

retentive coil functions such as

ä, S, R can be used several

times if required by the circuit diagram logic.

Exception: When using jumps to structure a circuit diagram,
this coil function can also be used effectively several times.

Relay with contactor function

Ä

The output signal follows immediately after the input signal
and the relay acts as a contactor.

Representation in easy:

• Output relays Q:

ÄQ1 to ÄQ8 (depending on type)

•Markers M, N:

ÄM1 to ÄM16, ÄN1 to ÄN16

• Function relays (Text) D: ÄD1 to ÄD16

• Output relays S: ÄS1 to ÄS8

•Jumps: Ä:1 to Ä:8

h

The coil functions Ä, Å, è, È, (contactor, contactor

negated, cycle pulse negative, rising edge) must only be
used once for each relay coil. The last coil in the circuit
diagram determines the status of the relay.

When controlling a contactor or relay, the control coil is
only present once. If you are creating parallel circuits, use
Set, Reset as a coil function.

Contactor function with negated result (inverse
contactor function)

Å

The output signal is simply an inversion of the input signal;
the relay operates like a contactor with contacts that have
been negated. If the coil is triggered with the 1 state, the coil
switches its make contacts to the 0 state.

Falling edge evaluation (cycle pulse) è

This function is used if the coil is only meant to switch on a
falling edge. With a change in the coil state from 1 to 0, the
coil switches its make contacts to the 1 state for one cycle.

The relay picks up when latched and remains in this state
until it is reset by the “unlatch” function.
