• The functional earth (FE) must beconnected to the protective earth (PE) or
to the potential equalisation. The systeminstaller 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.

• Deviations of the mains voltage from therated 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

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

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

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

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

Target readershipeasy

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 andcreating circuit diagrams. When active components such as
motors or pressure cylinders are controlled, parts of thesystem can be damaged and persons put at risk if easy isconnected or programmed incorrectly.

Proper use

easy is a programmable switching and control device and isused as a replacement for relay and contactor control
circuits. easy may only be operated when it has beencorrectly 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 toprevent accidental contact.
• The installation must comply with regulations forelectromagnetic 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.

A short current surge will be produced when switching on
for the first time. Do not switch on easy by means of reed
contacts since these may burn or melt.

• 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 thephase 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

Caution!
Do not use reed relay contacts at I7, I8. These may burn or
melt due to the high inrush current of I7, 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 isrequired 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 andI12, can be used to connect analog voltages ranging from
0 V to 10 V. A simple additional circuit also allows theanalog 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.

Connecting the inputs

Caution!
Analog signals are more sensitive to interference thandigital signals. Consequently, greater care must be taken
when laying and connecting the signal lines.
Incorrect switching states may occur if they are notconnected correctly.
Safety measures with analog signals
X Use shielded twisted pair cables to prevent interferencewith 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 inequalisation 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!
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.

47

05/04 AWB2528-1508GB

Installation

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 thereference potential of the DC power feed of analog sensors
must be electrically connected.

hEnsure that the common reference potential is groundedor monitored by a ground fault monitoring device. Observe
the requirements of the relevant regulations.

Up to four outputs can be connected in parallel in order toincrease the power. The output current will increase in thiscase to a maximum of 2 A.

i

Caution!
Outputs may only be connected in parallel within a group(Q1 to Q4 or Q5 to Q8, S1 to S4 or S5 to S8), such as Q1
and Q3 or Q5, Q7 and Q8. Outputs connected in parallel
must be switched at the same time.

i

Caution!
Please note the following when switching off inductive
loads.
Suppressed inductive loads cause less interference in theentire electrical system. For optimum suppression the
suppressor circuits are best connected directly to the
inductive load.

Installation

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 theworst possible case. If in the event of an emergency stop the+24 V DC power supply is to be switched off by means of acontact, 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

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 andthe current involved. If the fault condition persists, theoutput will keep switching off and on until the fault iscorrected or until the power supply is switched off(a section “Monitoring of short-circuit/overload with
EASY..-D.-T..”, page 242).

Connecting bus systemsh

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.
Only one device (expansion device or bus connection) can
be connected to the EASY-LINK connection.
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 thatthe bus system supports this.
• If the bus system or bus gateway is capable of this,function block, date, time parameters can be read andwritten via the bus. The states of inputs, outputs, markers
can be read.

h

The range and the functions of the bus gateways are being
continually further developed.
The current Moeller product line catalogue and theInternet online catalogue contain those bus gateways thatare currently available.

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 ofa few buttons, the easy circuit diagram produces all thewiring. All you have to do is then connect any switches,
sensors, lamps or contactors you wish to use.

Operation of easy

Circuit diagram
The circuit diagram is that part of the program where thecontacts are connected together. In RUN mode a coil isswitched on and off in accordance with the current flow andthe 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 andcoils as required. In RUN mode the function relays areprocessed 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 electronicallysimulated in easy. They actuate their contacts according totheir designated function. A relay consists of at least a coiland 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 theeasy circuit diagram can be defined as either a make contact
or a break contact.

77

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 coilfunctions.

To ensure compatibility with easy400 and easy600
devices, each easy500 and easy700 is provided logicallywith all possible contacts. If contacts are not supported by
the device, i.e. devices without a clock, their switchingstate is always zero. The contacts (make contact) of thetime 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.

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 withconnections.
• 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.

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 apower failure the data will be retained until the next time itis overwritten or deleted.
Memory card
Each EASY-M-32K memory card contains a circuit diagram
which is inserted into the easy interface. The program isstored retentively on the memory card.
The way the memory card works and a description of how totransfer a program to the card is given in section “Memorycard” on page 248.

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 isonly present once. If you are creating parallel circuits, use
Set, Reset as a coil function.
Rules for wiring relay coils
To ensure a clear overview of all relay states only assign thesame 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.

Analog value comparator/
threshold value switch

easy provides 16 analog comparators A1 to A16 for use as
required. These can also be used as threshold value switches
or comparators.
An analog value comparator or threshold value switch
enables you to compare analog input values with a setpoint,
the actual value of another function relay or another analog
input. This enables you to implement small controller tasks
such as two-point controllers very easily.
All easy-AB, easy-DA and easy-DC devices are provided withanalog inputs.
• The analog inputs of the easy500 are I7 and I8.
• The analog inputs of the easy700 are I7, I8, I11 and I12hCompatibility with easy400 and easy600
If you have loaded an existing easy400 or easy600 circuit
diagram, the previous comparator functions and values
are retained. The analog value comparator function relay
can work in easy500 and easy700 in the same way as ineasy400, easy600. The setpoints are converted to the newresolution of the analog inputs. The setpoint 5.0 (easy400,
easy600) is converted to the setpoint 512 (easy500,
easy700).

The analog value comparator for easy500 and easy700
operates internally in the value range:–2147483648 to +2147483647
This ensures that the correct value is always calculated.
This is important for multiplying values (I1 x F1 or I2 x
F2).
Example:I1 = 9999, F1 = 9999
I1 x F1 = 99980001
The result is within the value range.

h

If no value is entered at F1 or F2, only the value at I1 andI2 is used (no multiplication).

The analog signal from 0 to 10 V DC is converted to a 10-bit
digital value from 0 to 1023. A digital value of 100
represents an analog value of 1.0 V (exactly 0.98 V).

The GT, GE, LT, and LE comparison functions only differ inthe fact that GE and LE also switch when the value is equal
to the setpoint. easy500 and easy700 feature fivecomparison modes so that all analog value comparatorsfrom easy400 to easy800 are compatible.
Caution!
Analog signals are more sensitive to interference thandigital signals. Consequently, more care must be taken
when laying and connecting the signal lines.
Set the switching hysteresis to a value so that interference
signals will not cause accidental switching. A value of 0.2
V (value 20 without gain) must be observed as a safetyvalue.

Counters

easy provides 16 up/down counters C1 to C16 for use as
required. The counter relays allow you to count events. You
can define an upper threshold value as a comparison value.
The contact will switch according to the actual value.
High-speed counters, frequency counters up to 1 kHz
counter frequency.
easy-DA and easy-DC feature four high-speed counters C13
to C16. The function is defined by the mode selected. The
counter input is connected directly to a digital input. The
high-speed digital inputs are I1 to I4.
Possible applications include the counting of components,
lengths, events and frequency measurement.

Retention
Counter relays can be operated with retentive actual values.
You can select the retentive counter relays in the SYSTEM…

If a counter relay is retentive, the actual value is retained
when the operating mode changes from RUN to STOP as
well as when the power supply is switched off.
When easy is restarted in RUN mode, the counter relay
continues with the retentively stored actual value.
Determining counter frequency
The maximum counter frequency depends on the length ofthe circuit diagram in easy. The number of contacts, coils andrungs used determines the run time (cycle time) required toprocess the easy circuit diagram.
Example: When using EASY512-DC-TC with only three rungs
for counting, resetting and outputting the result via theoutput, the counter frequency may be 100 Hz.

120

05/04 AWB2528-1508GB

Counters

The maximum counter frequency depends on the maximum
cycle time.
The following formula is used to determine the maximum
counter frequency:
fc =

1

x 0.8

2 x tcfc = maximum counter frequency
tc = maximum cycle time
0.8 = Correction factor

ExampleThe maximum cycle time is tc = 4000 ms (4 ms).

High-speed counters,easy-DA, easy-DC

easy provides various high-speed counter functions. These
counter function blocks are coupled directly to digital inputs.
The following functions are possible:• Frequency counters: C15 and C16• High-speed counters: C13 and C14.

Frequency counterseasy provides two frequency counters C15 and C16 for use as
required. The frequency counters can be used for measuring
frequencies. The high-speed frequency counters arepermanently connected to the digital inputs I3 and I4.
Frequency counters C15 and C16 can be used for
determining motor speeds, volume measurement using
volume meters or the running of a motor.

125

05/04 AWB2528-1508GB

Wiring with easy

The frequency counter allows you to enter an upper
threshold value as a comparison value. The C15 and C16
frequency counters are not dependent on the cycle time.
Counter frequency and pulse shape
The maximum counter frequency is 1 kHz.
The minimum counter frequency is 4 Hz.
The signals must be square waves. We recommend a markto-space ratio of 1:1.
If this is not the case:
The minimum mark-to-space ratio is 0.5 ms.
tmin = 0.5 x.

1
fmax

tmin = minimum time of the pulse or pause duration
fmax = maximum count frequency (1 kHz)hFrequency counters operate independently of the program
cycle time. The result of the actual value setpointcomparison is only transferred once every program cycle
for processing in the circuit diagram.
The reaction time in relation to the setpoint/actual value
comparison can therefore be up to one cycle.
Measurement method
The pulses on the input are counted for one second
irrespective of the cycle time, and the frequency isdetermined. The measurement result is provided as an actual
value.
Wiring of a frequency counter
The following assignment of the digital inputs apply.
• I3 counter input for frequency counter C15• I4 counter input for frequency counter C16.

If you use C15 or C16 as frequency counters, coils DC15 orDC16 will have no function. The counter signals aretransferred directly from the digital inputs I3 and I4 to thecounters. A frequency counter measures the actual value

High-speed counters, easy-DA,
easy-DC

High-speed counter
You can use the high-speed counters to count highfrequency signals reliably.
easy provides two high-speed up/down counters C13 andC14 for use as required. The high-speed counter inputs arepermanently connected to the digital inputs I1 and I2. These
counter relays allow you to count events independently of
the cycle time.
The high-speed counters allow you to enter an upper
threshold value as a comparison value. The C13 and C14
high-speed counters are not dependent on the cycle time.
Counter frequency and pulse shape
The maximum counter frequency is 1 kHz.
The signals must be square waves. We recommend a markto-space ratio of 1:1.
If this is not the case:
The minimum mark-to-space ratio is 0.5 ms.
tmin = 0.5 x.

1
fmax

tmin = minimum time of the pulse or pause duration
fmax = maximum count frequency (1 kHz)h

High-speed counters operate independently of the
program cycle time. The result of the actual value setpointcomparison is only transferred once every program cycle
for processing in the circuit diagram.
The reaction time in relation to the setpoint/actual value
comparison can therefore be up to one cycle in length.
Wiring of a high-speed counter
The following assignment of the digital inputs apply.
• I1: high-speed counter input for counter C13.
• I2: high-speed counter input for counter C14.

If you use C13 or C14 as high-speed counters you must
enable them with the coil CC13 or CC14 accordingly.

The high-speed counter can also be enabled specificallyfor a special operating state. This has the advantage thatthe cycle time of the device is only burdened with thecounting when it is taking place. If the high-speed counteris not enabled, the cycle time of the device is shorter.

Retention
The high-speed counter can be run with the retentive actual
value. You can select the retentive counter relays in the

If a counter relay is retentive, the actual value is retained
when the operating mode changes from RUN to STOP as
well as when the power supply is switched off.
When easy is restarted in RUN mode, the counter relay
continues with the retentively stored actual value.

In the examples it must be remembered that there may be
a time difference of up to one program cycle between the
setpoint/actual value comparison and the processing of
the result. This may cause deviations in values.
Example: counting measuring pulses and setting an
outputMeasuring pulses can represent lengths, rotations, angles orother values. These program sections are required for
applications involving the filling of sacks, bags or the cuttingof foil.
The count signals are continuously present at I1. The highspeed counter C13 counts these pulses. The counter is
automatically set to zero if the actual value equals the
setpoint. Contact C13 is then set for one program cycle. The
output Q3 is set at the same time. This is then reset by input
I8.

Wiring with easy

Example running motors or spindles in parallel.
Applications may involve motion control with the parallel
control of two drives. Only certain deviations are permissible
so that the mechanical system does not jam.
These tasks can be implemented with the following solution.
I8 starts the drives. I7 and I6 carry the feedback signals of the
motor-protective circuit-breakers. The drives are stopped if a
motor-protective circuit-breaker trips. The analog value
comparators control the difference of the path distance. The
appropriate drive is stopped temporarily if one path distanceis outside of the set tolerance. The coils and contacts havethe following meanings:• M8 = enable for all drives• Q1 = drive 1, counter drive 1 is connected with input I1
and this with high-speed counter C13.
• Q2 = drive 2, counter drive 2 is connected with input I2
and this with high-speed counter C14.
• A1 = comparison, if C13 is less than C14, drive 2 is too
fast.
• A2 = comparison, if C14 is less than C13, drive 1 is too
fast.
• A3 = comparison, if C13 and C14 are equal, both drives
can be activated.
• The hysteresis value of A1, A2 and A3 depends on the
resolution of the transducer and the mechanical system.

Timing relays

easy provides 16 timing relays T1 to T16 for use as required.
A timing relay is used to change the switching duration andthe make and break times of a switch contact. The delay
times can be configured between 2 ms and 99 h 59 min. You
can use positive values, values of analog inputs, actual
values of counter relays and timing relays.
You can also use easy as a multi-function relay in theapplication. easy is more flexible than any hardwired timing
relay since you can wire all the functions at the push of abutton as well as program additional functions.

h

The timing relays of easy500 and easy700 function in thesame way as the timing relays of easy400 and easy600.
Exception: The “flash” function starts on easy500 andeasy700 with the pulse. With easy400 and easy600 the“flash” function starts with the pause. If required, thesame timing relays can also be used for retentive data.

Retention
Timing relays can be run with retentive actual values. Selectthe number of retentive timing relays in the SYSTEM… r
RETENTION… menu. T7, T8, T13 to T16 can be used asretentive timing relays.
If a timing relay is retentive, the actual value is retained
when the operating mode is changed from RUN to STOP andwhen the power supply is switched off.
When easy is restarted in RUN mode, the timing relay
continues with the retentively stored actual value.

hWhen easy is restarted, the status of the trigger pulse must
be the same as on disconnection.
Status 1 with all operating modes:• on-delayed,• single pulse,• flashing.
Status 0 with all operating modes: off-delayed.

Year time switch

easy500 and easy700 devices with the type designationeasy...-..-.C. are equipped with an integrated real-time clockthat you can use as a 7-day time switch and year timeswitch. If you have to implement special on and off switching
functions on public holidays, vacations, company holidays,
school holidays and special events, these can be
implemented easily with the year time switch.

h

The procedure for setting the time is described under
section “Setting date, time and daylight saving time”,
page 213.
easy offers eight year time switches Y1 to Y8 for up to 32
switch times.
Each time switch has four channels which you can use to set
four different on and off times. The channels are set via theparameter display.
The time and date are backed up in the event of a power
supply failure and continue to run. This means that it willcontinue to run in the event of a power failure, although thetime switch relays will not switch. When easy is in a deenergized state, the timer contacts remain open. Refer tosection “Technical Data”, page 264 for information on thebuffer time.

The master reset function relay enables you to set with one
command the status of the markers and all outputs to “0”.
Depending on the operating mode of this function relay, it ispossible to reset the outputs only, or the markers only, orboth. Three function blocks are available.
Wiring of the master reset function relay
You integrate a master reset function relay into your circuitin the form of a contact and coil.
The coils and contacts have the following meanings:

Operating modes
The different coils of the master reset have different
operating modes• Z1: For Q outputs: controls outputs Q1 to Q8 and S1 to S8.
• Z2: For markers M, N: controls the marker range M1 to
M16 and N1 to N16.
• Z3: for outputs and markers: controls Q1 to Q8, S1 to S8,
M1 to M16 and N1 to N16.

Function of the master reset function relay
A rising edge or the 1 signal on the coil will reset the outputs
or markers to 0, depending on the operating mode set. The
location of the coil in the circuit diagram is of no importance.
The master reset always has the highest priority.
The contacts Z1 to Z3 follow the status of their own coil.

Latching circuits are used to switch machines on and off. The
machine is switched on at the input terminals via makecontact S1 and is switched off via break contact S2.

188

05/04 AWB2528-1508GB

Basic circuits

S2 breaks the connection to the control voltage in order toswitch off the machine. This ensures that the machine can beswitched off, even in the event of a wire break. I2 is always
closed when not actuated.
I1-------SQ1
i2-------RQ1

S1 make contact at I1
S2 break contact at I2

A self-latching circuit with wire break monitoring canalternatively be wired using the Set and Reset coil functions.
If I1 is activated, coil Q1 latches. I2 executes the breakcontact signal from S2 and does not switch until S2 isactuated. In this way, the machine is switched off if or whena wire breaks.
Make sure that both coils are wired up in the correct order inthe easy circuit diagram: first wire the S coil and then the R
coil. This will ensure that the machine will be switched off
when I2 is actuated, even if I1 is switched on.

4x shift register
You can use a shift register for storing an item of
information, such as for the sorting of parts into good andbad, for two, three or four transport steps further on.
A shift pulse and the value (0 or 1) to be shifted are needed
for the shift register.
The shift register's Reset input is used to clear any values
that are no longer needed. The values in the shift register gothrough the register in the order: 1st, 2nd, 3rd, 4th storage
location.

Figure 77: easy circuit diagram shift register

How does the shift register work?
The shift pulse is activated for exactly one cycle. To do this,the shift pulse is generated by evaluating the change from I1
OFF to I1 ON – the rising edge.
In this way, therefore, the cyclical processing of easy is used
to trigger the shift pulse.
When I1 is activated for the first time, the marker relay breakcontact M7 is closed during the first pass through the cycle.
Thus, the series circuit consisting of I1, break contact M7(closed) and M8 is activated. Although M7 is now also
activated, this does not yet have any effect on contact M7.
The contact of M8 (make contact) was still open during thefirst cycle so a shift pulse cannot yet be generated. When therelay coil M8 is activated, easy transfers the result to thecontacts.

195Wiring with easy

05/04 AWB2528-1508GB

In the second cycle break contact M7 is open. The series
circuit is opened. The contact M8 is activated from the resultof the first cycle. Now, all the storage locations are either set
or reset in accordance with the series circuit.
If the relay coils were activated, easy transfers the result tothe contacts. M8 is now open again. No new pulse can beformed until I1 has opened, since M7 is open for as long as
I1 is closed.
How does the value reach the shift register?
When shift pulse M8 = ON, the state of I2 (VALUE) istransferred to storage location M1.
If I2 is activated, M1 is set. If I2 is deactivated, M1 isdeactivated via break contact I2.
How is the result shifted?
easy activates the coils in accordance with the rung and its
result, from top to bottom. M4 assumes the value of M3(value 0 or 1) before M3 assumes the value of M2. M3assumes the value of M2, M2 the value of M1 and M1 thevalue of I2.
Why are the values not constantly overwritten?
In this example, the coils are controlled only by the S and R
functions, i.e. the values are retained in on or off states eventhough the coil is not constantly activated. The state of thecoil changes only if the rung up to the coil is activated. In thiscircuit, the marker relay is therefore either set or reset. The
rungs of the coils (storage locations) are only activated via
M8 for one cycle. The result of activating the coils is storedin easy until a new pulse changes the state of the coils.

19605/04 AWB2528-1508GB

Example circuits

How are all the storage locations cleared?
When I3 is activated, all the R coils of storage locations M1
to M4 are reset, i.e. the coils are deactivated. Since the reset
was entered at the end of the circuit diagram, the resetfunction has priority over the set function.
How can the value of a storage location betransferred?
Use the make or break contact of storage locations M1 to
M4 and wire them to an output relay or in the circuit diagram
according to the task required.

Running light
An automatic running light can be created by slightly
modifying the shift register circuit.
One relay is always switched on. It starts at Q1, runs throughto Q4 and then starts again at Q1.
The marker relays for storage locations M1 to M4 are
replaced by relays Q1 to Q4.

Retention (non-volatiledata storage)h

It is a requirement of system and machine controllers for
operating states or actual values to have retentive settings.
What this means is that the values will be retained safely
even after the supply voltage to a machine or system has
been switched off, and will also be retained until the nexttime the actual value is overwritten.
Factory setting:
The retention function is not activated.

Permissible markers and function relays
It is possible to retentively store (non-volatile memory) the
actual values (status) of markers, timing relays and up/down
counters.
The following markers and function relays can be set to haveretentive actual values:• Markers M9 to M12, M13 to M16, N9 to N16• Up/down counters: C5, C6, C7, C8, C13 to C16• Text function relays: D1 to D8• Timing relays: T7, T8, T13 to T16hTo ensure that easy500 and easy700 are fully compatible
with easy400 and easy600 devices, the retentive datasettings were divided into the above areas.

Deleting retentive actual values
The retentive actual values are cleared if the following isfulfilled (applies only in STOP mode):• When the circuit diagram is transferred from EASY-SOFTBASIC or the memory card to the easy control relay, theretentive actual values are reset to 0. This also applies
when there is no program on the memory card. In this casethe old circuit diagram is retained in easy.
• When the selected retentive markers, function relays ortext display are deactivated.
• When the circuit diagram is deleted via the DELETE FUNCTmenu.
The operating hours counters are always retentive. The
actual values can only be reset by means of a special reset
operation from the circuit diagram.

Transferring retentive behaviour
The setting for retentive behaviour is a circuit diagram
setting; in other words, the retention setting is on thememory and is transferred with the circuit diagram when
uploading or downloading from the PC.

together with their actual values. The actual values of relays
no longer being used are also retained.
Changing the operating modeIf you change from RUN to STOP and then back to RUN, theactual values of the retentive data will be retained.
Modifying the easy circuit diagram
If a modification is made to the easy circuit diagram, theactual values will be retained.

hAttention!
Even if the markers and function relays that were retentive
are deleted from the circuit diagram, the retentive actual
values remain when changing from STOP to RUN, andwhen switching the device off and on. Should these relays

easy circuit diagram cycle

Inside easy

In conventional control systems, a relay or contactor control
processes all the rungs in parallel. The speed with which acontactor switches in this case depends on the components
used, and ranges from 15 to 40 ms for relay pick-up anddrop-out.
With easy the circuit diagram is processed with amicroprocessor that simulates the contacts and relays of thecircuit concerned and thus processes all switching
operations considerably faster. Depending on its size, theeasy circuit diagram is processed cyclically every 2 to 40 ms.
During this time, easy passes through five segments insuccession.

In the first three segments easy evaluates the contact fields
in succession. As it does so, easy also checks whether thecontacts are connected in parallel or series and stores theswitching states of all the contact fields.
In the fourth segment, easy assigns the new switching statesto all the coils in one pass.

235

Inside easy

05/04 AWB2528-1508GB

The fifth segment is outside the circuit diagram and easy
uses it to establish contact to the “outside world”: The
output relays Q1 to Q... are switched and inputs I1 to I.. areread again. easy also copies all the new switching states tothe status image register.
easy only uses this status image for one cycle. This ensuresthat each rung is evaluated with the same switching statesfor one cycle, even if the input signals at I1 to I12, forexample, change their status several times within a cycle.
Evaluation in the circuit diagram and high-speed
counter functions
When using high-speed counter functions, the signal state iscontinuously counted or measured irrespective of theprocessing of the circuit diagram. (C13, C14 high-speed up/
down counters, C15, C16 frequency counters)

easy operation and effects on circuit diagram
creationeasy evaluates the circuit diagram in these five segments insuccession. You should therefore remember two points
when you create your circuit diagrams:• The changeover of a relay coil does not change theswitching state of an associated contact until the next
cycle starts.
• Always wire forwards, upwards or downwards. Never wirebackwards.

• Contact Q1 remains switched off since easy evaluatesfrom left to right.

Depending on the type of easy in use, it is possible to use theinternal inputs I15 and I16, R15, R16 to monitor for shortcircuits or overloads on an output.
• EASY512-...-T..:
I16 = Group fault alarm for outputs Q1 to Q4.
• EASY721.-..-T..:– I16 = Group fault alarm for outputs Q1 to Q4.
– I15 = Group fault alarm for outputs Q5 to Q8.

additional feature is that when an overload is detected, theindicator light at Q4 is actuated. If Q4 has an overload, itwould 'pulse'.

Example 3: Automatic reset of error signal
The circuit diagram functions in the same way as Example 2.
In addition the marker M16 is reset every 60 seconds bytiming relay T8 (on-delayed, 60 s). Should I16 remain at 1,
M16 will continue to be set. Q1 is set briefly to 1 until I16
switches off again.

You can expand easy700 with EASY618-..-RE, EASY202-RE
or EASY620-D.-TE modules locally or use the EASY200-EASY
coupling module for remote expansion.
For this first install the units and connect the inputs andoutputs (a chapter “Installation”, page 31).
You process the inputs of the expansion devices as contacts
in the easy circuit diagram in the same way as you process
the inputs of the basic unit. The input contacts are assigned
the operand identifiers R1 to R12.
R15 and R16 are the group fault alarms of the transistor
expansion unit (a section “Monitoring of short-circuit/overload with EASY..-D.-T..”, page 242).
The outputs are processed as relay coils or contacts like theoutputs in the basic unit. The output relays are S1 to S8.

h

EASY618-..-RE provides the outputs S1 to S6. The other
outputs S7, S8 can be used as markers.
The following bus modules can also be connected:• EASY205-ASI (AS-Interface),• EASY204-DP (Profibus DP),• EASY221-CO (CANopen) or• EASY222-DN (Device NET).

Function monitoring of expansion units
If the power supply of the expansion unit is not present, noconnection can be established between it and basic unit. The
expansion inputs R1 to R12, R15, R16 are incorrectly
processed in the basic unit and show status 0. It cannot be
assured that the outputs S1 to S8 are transferred to the
expansion unit.

jWarning!
Ensure the continuous monitoring of easy expansion
devices in order to prevent switching faults in machines orsystems.

I14--------Ä:8

I1uI2----ÄQ1
Q1k:8

When the power supply is switched on, basic units andexpansion devices may require different power up times toreach full functionality. If the basic unit is powered up
faster, the internal monitoring input I14 will have status 1,
indicating that an expansion device is not functional.
ExampleThe expansion unit may be powered up later than the basic
unit. This means that the basic unit is switched to RUN whenan expansion unit is missing. The following easy circuit
diagram detects if the expansion unit is functional or not
functional.
As long as I14 is 1, the remaining circuit diagram is skipped.
If I14 is 0, the circuit diagram is processed. If the expansion
unit drops out for any reason, the circuit diagram is skipped.
M1 detects whether the circuit diagram was processed for atleast one cycle after the power supply is switched on. If thecircuit diagram is skipped, all the outputs retain theirprevious state. The next example should be used if this is notdesired.

information is transferred via the easy interface.
This has the advantage that easy can be operated remotely.
The texts in easy are backlit and displayed on the front of theoperator or control panel in twice the size. The display/
operating unit provides protection to IP65.

Inside easy

If a display/operating unit with a keypad is used, easy can be
programmed and assigned parameters from “outside”.

hCard mode operation is not possible when using a standalone display/operating unit. The interface can only be
used once.
The MFD-80 (IP65 display unit), MFD-80-B (IP65 display/
operating unit) with the MFD-CP4-500 power supply/
communication unit are currently available for use as standalone display/operating units.

hDevice version

The MFD-CP4 communication unit establishes permanentcommunication with the easy control relay. This increases
easy's cycle time, and must be taken into account during
engineering.

Every easy has the device version number printed on the leftof the device housing. The device version is indicated by the
first two digits of the device number.
DC 20.4 …28.8 V

Figure 93: Example of device version

This device is of device version 01.
The device version provides useful service information about
the hardware version and the version of the operating
system.The device version is important for selecting thecorrect control relay for EASY-SOFT-BASIC.

Glossary

Analog input

The device easy-AB, easy-DA and easy-DC are provided withthe two (easy500) and four (easy700) analog inputs I7, I8
and I11,I12. The input voltage range is 0 V to 10 V. The
measuring data is evaluated with the integrated function
relays.

Circuit diagram elements

As in conventional wiring, the circuit diagram is made up of
circuit elements. These include input, output and marker
relays, plus function relays and P buttons.

Connect mode

Connect mode is used to wire up the circuit elements in youreasy circuit diagram.

Contact behaviour

The contact behaviour of any circuit element can be definedas either a break contact or a make contact. Break contact
elements are identified by a line above the identifier(Exception: jump).

Entry mode

Entry mode is used to input or modify values when creating
circuit diagrams or setting parameters, for example.

Function relays

Function relays can be used for complex control tasks. easy
features the following function relays:• Timing relay• 7-day time switch• Year time switch• Counter, up/down, high-speed, frequency• Analog value comparator/threshold value switch• Operating hours counter• Master reset• Text marker relay283

Glossary

05/04 AWB2528-1508GB

Impulse relay

An impulse relay is a relay which changes its switching state
and retains its new state (latched) when a voltage is applied
to the relay coil for a short time.

Input

The inputs are used to connect up external contacts. In thecircuit diagram, inputs are evaluated via contacts I1 to I12
and R1 to R12.
easy-AB, easy-DA and easy-DC can also receive analog data
via the inputs I7, I8 and I11, I 12.

Interface

The easy interface is used to exchange and save circuit
diagrams to a memory card or PC.
Each memory card contains one circuit diagram and its
associated easy settings.
The EASY-SOFT-BASIC software allows you to control easy
from your PC which is connected using the easy-PC-CAB
cable.

Local expansion

I/O expansion with the expansion unit (e.g. EASY620-DC-TE)
installed directly on the basic unit. The connector is always
supplied with the expansion unit.

Memory card

The memory card is used to store your easy circuit diagram,
together with its parameter and easy settings. The data on
the memory card will be retained, even if the power supply
fails or is switched off.
The memory card is inserted into the interface slot on theeasy device.

Mode

284

easy has two operating modes: RUN and STOP. RUN modeis used to process your circuit diagram (with the controller
running continuously). In STOP mode you can create yourcircuit diagrams.

05/04 AWB2528-1508GB

Operating buttons

Glossary

easy has eight operating buttons. These are used to selectmenu functions and create circuit diagrams. The large roundbutton in the middle is used to move the cursor.
DEL, ALT, ESC and OK all perform additional functions.

OutputYou can connect various loads to the four easy outputs, suchas contactors, lamps or and motors. In the easy circuit
diagram the outputs are controlled via the corresponding
output relay coils Q1 to Q8 or S1 to S8.

P buttons

The P buttons can be used to simulate four additional inputs
which are controlled directly by the four cursor buttons,
rather than via external contacts. The switch contacts of P
buttons are connected up in the circuit diagram.

Parameters

Parameters enable the user to set the behaviour of a function
relay. Possible values include switching times or counter
setpoints. They are set in the parameter display.

Power supply

easy-AB is supplied with an 24 V AC supply. The terminals
are labelled “L” and “N”.
easy-AC is powered by AC voltage at 85 to 264 V AC, 50/60
Hz. The terminals are labelled “L” and “N”.
easy-DA is supplied with a 12 V DC supply. The terminals arelabelled +12 V and 0 V.
easy-DC is powered by DC voltage at 24 V DC. The terminals
are labelled “+24 V” and “0 V”.
The terminals for the power feed are the first three terminals
on the input side.

285

05/04 AWB2528-1508GB

Glossary

Remote expansion

I/O expansion with the expansion unit (e.g. EASY620-DC-TE)
installed up to 30 m away from the basic unit. The EASY200EASY coupling unit is fitted to the basic unit. The input andoutput data is exchanged between expansion and basic unit
via a two-wire cable.

Retention

Data is retained even after the easy power supply is switchedoff (retentive data)
The following data is retentive:• easy circuit diagram• Parameters, setpoint values• Texts• System settings• Password• Actual values of marker relays, timing relays, counters(selectable)

286

Retentive data

See Retention.

Rungs

Each line in the circuit diagram is a rung. easy500 andeasy700 can take 128 rungs.
