Warning!
Dangerous electrical voltage!
Before commencing the installation● Disconnect the power supply of thedevice.
● Ensure that devices cannot be
accidentally restarted.
● Verify isolation from the supply.
● Earth and short circuit.
● Cover or enclose neighbouring units thatare live.
● Follow the engineering instructions(AWA) of the device concerned.
● Only suitably qualified personnel inaccordance with EN 50 110-1/-2(VDE 0105 Part 100) may work on thisdevice/system.
● Before installation and before touching
the device ensure that you are free ofelectrostatic charge.
● 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 do not impair the
automation functions.
● Install automation devices and related

operating elements in such a way thatthey 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 theautomation devices.

● Ensure a reliable electrical isolation of

the low voltage for the 24 volt supply.
Only use power supply units complying
with IEC 60 364-4-41 (VDE 0100
Part 410) or HD 384.4.41 S2.
● Deviations of the mains voltage fromthe rated value must not exceed thetolerance limits given in the specifications, otherwise this may cause
malfunction and dangerous operation.
● Emergency stop devices complying with
IEC/EN 60 204-1 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.
● Measures should be taken to ensure theproper restart of programs interrupted
after a voltage dip or failure. This should
not cause dangerous operating stateseven for a short time. If necessary,
emergency-stop 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 operatingstate in the event of a fault or malfunction(for example, by means of separate limit
switches, mechanical interlocks etc.).

Instructions for Use“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 forcommissioning and creating circuit diagrams. Partsof the system can be damaged and persons put at
risk if “easy” is connected or programmed
incorrectly, causing active components such as
motors or pressure cylinders to start up.

Proper use“easy” is a programmable control and timing relay
which is used in place of relay and contactor
controls. It must not be used unless it has beencorrectly installed.

08/00 AWB2528-1304-GB“easy” is designed to be installed in an enclosure,switch cabinet or distribution board. Both thepower feed and the signal terminals must be laidand covered so as to prevent accidental contact.
The installation must conform to 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.

Overview“easy”“easy” is an electronic control relay with built-in
logic, timer, counter and time switch functions.
“easy” is a control and input device rolled into one
that can perform many different tasks in building andmachine applications.
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 andin parallel
Connect output relays and markers,
Define outputs as relays, impulse relays orlatching relays
Select timing relays with different functions
Assign eight up and down counters
Display any texts with variables,
Track the flow of current in the circuit diagram
Load, save and password-protect circuit
diagrams
Models with the type designation“EASY...-...-..-.C(X)” offer an additional four 7-daytime switches each allowing up to four On and Off
times.

08/00 AWB2528-1304-GB

The DC versions can receive analog signals at two
inputs and evaluate the signals with eight analog
comparators.
If you prefer to wire up “easy” from a PC, then use
EASY-SOFT. EASY-SOFT allows you to create andtest your circuit diagram on the PC. EASY-SOFT
enables you to print out your circuit diagram in DIN,ANSI or “easy” format.

Cable protection
Both “easy” AC and DC versions require cable
protection (F1) rated for at least 1 A (slow).
When “easy” is switched on for the first time, its
power supply circuit behaves like a capacitor.
Use an appropriate device for switching on the
power supply and do not use any reed relay
contacts or proximity switches.

“easy” inputs switch electronically. Once you haveconnected a contact via an input terminal, you canreuse it as a contact in your “easy” circuit diagram as
often as you like.

Neon bulbs with a maximum residual current of
2 mA/1 mA at 230 V/115 V can be connected to I7
and I8.
Always use neon bulbs that are operated with aseparate N connection.
Caution
Do not use reed relay contacts on I7, I8. Thesemay burn or melt due to the high inrush currentof I7, I8.
Two-wire proximity switches have a residual current
on 0. If this residual current is too high, the input of“easy” may only detect the 1 signal.

08/00 AWB2528-1304-GB

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

CautionAnalog signals are more sensitive to interference
than digital signals. Consequently, more caremust be taken when laying and connecting thesignal lines.
Incorrect switching states may occur if they are
not connected correctly.
Use screened twisted pair cables to prevent
interference with the analog signals.
For short cable lengths, ground the screen atboth ends using a large contact area. If the cable
length exceeds 30 m or so, grounding at bothends can result in equalisation currents between
the two grounding points and thus in theinterference of analog signals. In this case, only
ground the cable at one end.
Do not lay signal lines parallel to power cables.
Connect inductive loads to be switched via“easy” outputs to a separate power feed, or use a35

such as motors, solenoid valves or contactors areoperated with “easy” via the same power feed,
switching may result in interference on the analog
input signals.

Parallel connection:
Up to four outputs can be connected in parallel inorder to increase the power. The output current will
increase in this case to a maximum of 2 A.

CautionPlease note the following when switching off
inductive loads.
Suppressed inductive loads cause lessinterference in the entire electrical system. For
optimum suppression the suppressor circuits are
best connected directly to the inductive load.

42

08/00 AWB2528-1304-GB

Caution
Outputs may only be connected in parallel withina group (Q1 to Q4 or Q5 to Q8, S1 to S4 or S5 toS8), such as Q1 and Q3 or Q5, Q7 and Q8.
Outputs connected in parallel must be switchedat the same time.

Connecting transistor
outputs
If inductive loads are not suppressed, only one
inductive load should be switched off at any one time
so as to prevent the driver blocks from possibly
overheating. If in the event of an emergency stop the+24 V DC power supply is to be switched off bymeans 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 forthese loads (see the following diagrams).

Behaviour in the event of short-circuits/overload
Should a short circuit or overload occur on atransistor output, this output will switch off. The
output will switch on up to maximum temperature
after the cooling time has elapsed. This timedepends on the ambient temperature and the current
involved. If the fault condition persists, the output willkeep switching off and on until the fault is correctedor until the power supply is switched off.

Drawing a Circuit Diagramwith “easy”
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.

Once they have been saved, programs can bereloaded into “easy”, edited and run.
All circuit diagram data is saved in “easy”. In theevent of a power failure the data will be retained until
the next time it is overwritten or deleted.
Memory card
Each memory card contains a circuit diagram whichis inserted into the “easy” interface.
The way the memory card works and a description of
how to transfer a program to the card is given inchapter 6, from page 126.
EASY-SOFT
EASY-SOFT is an optional PC program with which
you can create, store, test (simulate) and manage“easy” circuit diagrams.
Completed circuit diagrams are transferred between
your PC and “easy” via the connecting cable. Onceyou have transferred a circuit diagram, simply run“easy” straight from your PC.

Marker relay M is used as a “flag”. The S relay can beused as the output of an expansion unit or as amarker if no expansion unit is connected. The only
difference between them and the output relay Q isthat they have no output terminals.

The functions of timer and counter relays are
explained in the relevant relay description.
The coil function Ä (contactor) should only be
used once for each coil. Otherwise the last coil inthe circuit diagram will determine the status of therelay.

73

Drawing a Circuit Diagramwith “easy”
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 canbe used several times if required by the circuit
diagram logic.
Exception: The coil function can be used properly
several times when using jumps to structure thecircuit diagram.
Rules for wiring relay coils
Use the contactor or “impulse relay” function once
only for each relay coil.
Only use the “latch” (S) and “unlatch” (R) functions
once to control each relay in order to ensure greater
clarity in the circuit diagram.
Relays with contactor function
The output signal follows
immediately after the input signal
and the relay acts as a contactor.

A function relay is started via its relay coil or byevaluating a parameter. It switches the contact of thefunction relay according to its function and the set
parameters.
Current actual values are cleared if the power
supply is switched off or if “easy” is switched toStop mode.
Exception: Retentive coils retain their state (seechapter 8, page 151).

Timing relays“easy” provides eight different timing relays T1 to T8
for use as required.
A timing relay is used to change the switching
duration and the make and break times of a relay
contact. The possible delay times range between
10 ms and 100 h.

Wiring a timing relay
A timing relay is integrated into your circuit in theform of a contact. The function of the relay is defined
via the parameter display. The relay is started via thetrigger input TRG and can be reset via the reset input
RES.
To prevent unpredictable switching states, useeach coil of a relay once only in the circuit

Counter relays“easy” works with counter relays C1 to C8.
DRCThe counter relay increments ordecrements signals andswitches when the actual value
is greater than or equal to the
setpoint value. Values between
0000 and 9999 are possible.

A counter relay can be controlled via the counting
pulse CCx, counting direction DCx and reset RCx

Counter relays
Wiring a counter relay
You integrate a counter relay into your circuit in theform of a contact and coil. Counter relay C1 receives
counting pulses via the count coil CC1. The counting
direction can be changed via the direction coil DC1:
DC1 = 0: relay C1 counts up
DC1 = 1: relay C1 counts down
The Reset coil RC1 is used to reset the counter to theactual value 0.

Contact C1 is used to process the result of thecounter in the circuit diagram.
To prevent unpredictable switching states, useeach coil of a relay once only in the circuit
diagram.

Drawing a Circuit Diagramwith “easy”
Determining counter frequency
The maximum counter frequency depends on thelength of the circuit diagram in “easy”. The number ofcontacts, coils and circuit connections used
determines the run time (cycle time) required toprocess the “easy” circuit diagram.
Example: When using EASY412-DC-TC with only
three circuit connections for counting, resetting andoutputting the result via the output, the counterfrequency may be 100 Hz.
To determine the cycle time refer to chapter 9 on
page 175.
The maximum counter frequency depends on the
maximum cycle time.
Use the following formula to determine the maximum
counter frequency:
1 -  0.8
fc = ---------------2  tc
fc = maximum counter frequency
tc = maximum cycle time
0.8 = correction factor
ExampleThe maximum cycle time is tc = 4000 s (4 ms).

Each time switch has four channels
which you can use to set four on and offtimes. The channels are set via theparameter display.
The timer has a back-up battery. This means that it
will continue to run in the event of a power failure,although the time switch relays will not switch. Whenthe timer is disconnected from the power supply, thecontacts remain open. Information on the battery

Analog comparators

Access enabled- Access disabled

Analog comparators are only available with 24 V
“easy”-DC models. They monitor the voltages of
sensors that are connected to terminals I7 and I8.

A comparator can perform six different
types of comparison. The relay contact
switches if the comparison conditions
are fulfilled.

98

08/00 AWB2528-1304-GB“easy” provides eight analog comparators “A1” to“A8” for use as required.

Analog comparators
I7  I8, I7  I8
I7  setpoint, I7  setpoint
I8  setpoint, I8  setpoint
Both the setpoint value and the actual value
correspond to the measured voltages.
Resolution of the voltage values:
0.0 to 10.0 V in 0.1 V steps
From 10 V to 24 V the actual value stays at 10.0.
You can enter the setpoint values for a comparison
while you are creating the circuit diagram or in theparameter display in Run mode.
Typical applications
Evaluating the analog values of sensors, e.g. inorder measure the pressure or temperature.
Two-step controllers
Example:I1uA1----SQ1
Analog comparator A1 latcheshA2----RQ1(sets) relay Q1 if the actual value
drops below the lower setpointvalue of 7.1 V. Comparator A2
unlatches (resets) the relay if itrises above the upper setpoint value of 7.5 V. Thus
the difference (switching hysteresis) between the twovoltage setpoint values is 0.4 V.

A1 sets relay output Q1 (A) up to a voltage of 7.1 V.
The hysteresis (B) is between 7.1 V and 7.5 V. At
7.5 V, A2 causes the relay to reset (C). Q1 drops out
and does not pick up again until A1 is set at 7.1 V (D).
Analog signals of sensors typically fluctuate by
several millivolts. For stable set and resetswitching the setpoints should differ by at least
0.2 V (switching hysteresis).

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

111

Drawing a Circuit Diagramwith “easy”
S2 opens the connection to the control voltage inorder to switch off the machine. This ensures that themachine can be switched off, even in the event of awire break. I2 is always closed when not actuated.

Set and Reset coil functions.

Relay Q1 is latched when I1 isswitched on. I2 inverts the breakcontact signal from S2 and does
not switch until S2 is actuated.
In this way, the machine is switched off if or when awire breaks.
Make sure that both coils are wired up in the correct
order in the “easy” circuit diagram: first wire the “S”
coil and then the “R” coil. This means that themachine will be switched off when I2 is actuated,even if I1 is switched on.

You can implement two star-delta circuits with“easy”. The advantage of “easy” is that you canselect any changeover time between star and deltacontactors and any wait time between switching off
the star contactor and switching on the deltacontactor.

4x shift register
You can use a shift register for storing an item of
information, such as the sorting of parts into goodand bad two, three or four transport steps further on.
A shift pulse and the value (0 or 1) to be shifted areneeded for the shift register.
The shift register's Reset input is used to clear any
values that are no longer needed. The values in theshift register pass through the register in thefollowing order.

How does the shift register work?
The shift pulse is switched on 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.

08/00 AWB2528-1304-GB

When I1 is switched on for the first time, marker relay
contact M7 is switched off and the break contact isclosed during the first pass through the cycle. Thus,
the series circuit consisting of I1, break contact M7(closed) and M8 is switched on. Although M7 isswitched on, this does not yet affect contact M7.
The contact of M8 (make contact) was still open
during the first cycle so a shift pulse cannot yet be
generated. When the relay coil M8 is activated,“easy” transfers the result to the contacts.
In the second cycle, break contact M7 opens. The
series circuit is now open. The contact M8 isswitched on from the result of the first cycle. Now, all117

Drawing a Circuit Diagramwith “easy”
the storage positions are either set or reset inaccordance with the series circuit.
If the relay coils were activated, “easy” transfers theresult to the contacts. M8 is now open once more.
No new pulse can be formed 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) is
transferred to storage position M1.
If I2 is switched on, M1 is set. If I2 is switched off, M1
is switched off via break contact I2.
How is the result shifted?
“easy” activates the coils in accordance with thecircuit connection and its result, from top to bottom.
M4 assumes the value of M3 (value 0 or 1) before M3
assumes the value of M2. M3 assumes the value of
M2, M2 the value of M1 and M1 the value 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 inon or off states even though the coil is not constantly
switched on. The state of the coil changes only if thecircuit connection up to the coil is switched on. In
this circuit, the marker relay is therefore either set or
reset.

How are all the storage positions cleared?
When I3 is switched on, all the “R” coils of storage
positions M1 to M4 are reset, i.e. the coils are
switched off. Since the reset was entered at the endof the circuit diagram, the reset function has priority
over the set function.

118

08/00 AWB2528-1304-GB

The circuit connections of the coils (storage
positions) are only switched on via M8 for one cycle.
The result of activating the coils is stored in “easy”
until a new pulse changes the state of the coils.

Example circuits
How can the value of a storage position betransferred?
Use the make or break contact of storage positions
M1 to M4 and wire them to an output relay or in thecircuit 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
through to Q4 and then starts again at Q1.
The marker relays for storage positions M1 to M4 are
replaced by relays Q1 to Q4.

08/00 AWB2528-1304-GB

The shift pulse I1 has been
automated by the flasher relay
T1. The cycle pulse M8 remains
as it is.

Retention

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 amachine or system has been switched off and arealso retained until the next time the actual value isoverwritten.

Requirements

Permitted “easy” models
Retentive actual values can be set with
EASY412-D.-.. (via the SYSTEM menu) as well as
EASY600 for the following markers and function
relays.
Permitted markers and function relays
It is possible to retentively store (non-volatilememory) the actual values (status) of markers, timing

Changing the operating mode or the circuit
diagramWhen the operating mode is changed or the “easy”
circuit diagram is modified, the retentive data isnormally saved together with their actual values. The
actual values of relays no longer being used are also

Changing the operating modeIf you change from Run to Stop and then back to
Run, the actual values of the retentive data will be
retained.
Modifying the “easy” circuit diagram
If a modification is made to the “easy” circuit
diagram, the actual values will be retained.
Note
Even when the retentive relays M13, M14, M15,
M16 (D1 to D8) and the function relays C8, T8(C5, C6, C7, T7) are deleted from the circuit
diagram, the retentive actual values will be
retained after the changeover from Stop to Run
as well as after the power supply is switched off

Set
Impulse relayReset

S M.., D..
äM.., D..
R M.., D..

Note
When the condition for resetting the marker isfulfilled, the marker is reset.
It is essential that you note the following points:
Due to the operation of “easy” the make contact willremain closed and the break contact will remain
open. If the Reset condition is active when the power
supply is switched on, the state of the contact before
power on will be retained for one cycle.
This behaviour can result in a flicker effect in a lamp
or a solenoid valve.
Be sure to pay close attention to the example circuits
for the individual coil functions.
The following coil functions are not permitted:
ÄM13 to ÄM16, ÄD1 to ÄD8

Task:
In your application you need to remember whether ascrew has been inserted or not. When yourinstallation switches on, it is important that a screw

T8 provides the clock pulse. When a time oft = 30 min. is selected the counting period amounts
to 2  t = 60 min. Every hour one impulse is counted.
The up counter C8 triggers a warning message at

Retention
M16 prevents C8 from accidentally receiving acounter pulse when the power is switched back on if
there was a power outage during the counting

Both M16 and C8 must retain their actual values at

Function of the “easy” circuit diagram:
T1 provides the clock pulse. When a time oft = 0.5 seconds is selected the counting periodamounts to 2  t = 1 s. One impulse is counted every
second.
The up counter C8 switches on valve Q1 via M15 at
3600 counting pulses (3600 s = 1 h).
M15 resets C8 and prepares C8 for the next hour. To
stop C8 continuing to count, the break contact of
M15 blocks the counting pulses.
T8 is actuated by means of M15. Once T8 has timed
out, M15 and T8 will be reset.
In order that both the time elapsed since the last
lubrication (counter C8) and also the lubrication
pulse remains constant in the event of a power
outage, C8, M15 and T8 must be retentive.

9“easy” circuit diagram
cycle

Inside “easy”

In conventional control systems, a relay or contactor
control processes all the circuit connections inparallel. The speed with which a contactor switches
is thus dependent on the components used, andranges from 15 to 40 ms for relay pick-up and dropout.
With “easy” the circuit diagram is processed with amicroprocessor that simulates the contacts andrelays of the circuit concerned and thus processes all
switching operations considerably faster. Depending
on its size, the “easy” circuit diagram is processed
cyclically every 4 to 40 ms.
During this time, “easy” passes through fivesegments in succession.
How “easy” evaluates the circuit diagram:

P1-kêê êêê...

I1-q1-j--ÄQ8

In the first three segments “easy” evaluates thecontact fields in succession. As it does so, “easy”
also checks whether contacts are connected inparallel or in series and stores the switching states of
all the contact fields.

175

Inside “easy”
In the fourth segment, “easy” assigns the newswitching states to all the coils in one pass.
The fifth segment is outside the circuit diagram.
“easy” uses this to “make contact” with the outside
world: Output relays Q1 to Q.. are switched andinputs I1 to I.. are read once more.
“easy” also copies all the new switching states to thestatus image register.
“easy” only uses this status image for one cycle. This
ensures that each circuit connection is evaluatedwith the same switching states for one cycle, even if
the input signals I1 to I12 change their status several
times within a cycle.

How does this affect the creation of the circuit
diagram?
“easy” evaluates the circuit diagram in these fivesegments in succession. You should therefore
remember two points when you create your circuit
diagrams:

176

08/00 AWB2528-1304-GB

The changeover of a relay coil does not change
the switching state of an associated contact until
the next cycle starts.
Always wire forward or from top to bottom. Neverwork backwards.

Determining the cycle timeof “easy” circuit diagrams
Example: Switching one cycle later
This is the circuit diagram of a Circuit diagram:self-latching circuit. If I1 and I2
I1uI2----ÄQ1
are closed, the switching stateof relay coil ÄQ1 is “latched” via Q1k
contact Q1.
1st cycle: I1 and I2 areswitched on. Coil ÄQ1 picks Start condition:
I1, I2 switched onup.
Q1 switched off.
Contact Q1 remains
switched off since “easy”
evaluates from left to right.
2nd cycle: The self-latching function now
becomes active. “easy” has transferred the coilstates to contact Q1 at the end of the first cycle.
Example: Do not wire backwards
This example is shown in
I1-Q4-i3ochapter 5. It was used in thez-----ksection „Creating andmodifying connections“ tohI2-I4-ÄQ2
illustrate how NOT to do it.
In the third circuit connection,“easy” finds a connection to the second circuit
connection in which the first contact field is empty.
The output relay is not switched.

When wiring more than threecontacts in series, use one of
the marker relays.

This function is useful, forexample, in order to ensure aclean switching signal despite
contact bounce.
“easy”-DC, “easy”-DA and “easy”-AC units function
with different input voltages and therefore also havedifferent evaluation methods and delay times.

The debounce for DC signals is 20 ms.

An input signal S1 must therefore be 15 V for at least
20 ms on the input terminal before the switch contact
will change from 0 to 1 (A). If applicable, this timemust also include the cycle time (B) since “easy”
does not detect the signal until the start of a cycle.

184

08/00 AWB2528-1304-GB

The same debounce delay (C) applies when thesignal drops out from 1 to 0.

I7 and I8: 0.2 ms
Check that there is no interference affecting the
input signals when the debounce delay isswitched off. “easy” will respond even to very
short signals.
Debounce delay times for “easy”-AC basic units
The input debounce with AC voltage signals
depends on the frequency:

If the debounce delay is switched on, “easy” checks
at 40 ms (33 ms) intervals whether there is a halfwave present at an input terminal (1st and 2nd pulsesin A). If “easy” detects two pulses in succession, thedevice switches on the corresponding input
internally.
If this is not the case, the input is switched off again
as soon as “easy” does not detect two successive
half-waves (1st and 2nd pulses in B).

Depending on the type of “easy” in use, it is possible
to use the internal inputs I15 and I16, R15, R16 tomonitor for short-circuits or overloads on an output.

Transfer EASY-D.-T.. ➞ Memory card ➞EASY..-..-R...
I16 is added during transfer of the circuit diagram
into “easy” from the memory card. I16 appears as I16
and the logical state remains 0 = switched off (makecontact).
If I16 is changed in any way, only I1 to I8 can beentered. I16 can be deleted with the DEL button.
Transfer EASY-D.-T.. ➞ EASY-SOFT (PC)EASY-SOFT, Version 1.0, cannot process input I16.
I16 is deleted during the transfer to EASY-SOFT.
EASY-SOFT, Version 1.1, tolerates I16 without
editing being possible. I16 is transferred when thecircuit diagram is downloaded.



I16 should be evaluated in accordance with theindividual application.
I15, I16 can only be edited with “easy” versions
which have transistor outputs.
The following examples are for I16 = Q1 to Q4. I15
indicates in the same way short-circuits andoverloads on Q5 to Q8.

Expanding EASY600

You can expand “easy” models EASY619/621-...
locally using the expansion units EASY618-..-RE or
EASY620-D.-TE or remotely – using the EASY200EASY coupling module.
For this first install the units and connect the inputs
and outputs (see chapter 3, Installation).
Incorporate the inputs of the expansion units as
contacts in the “easy” circuit diagram like the inputs
in the basic unit. The input contacts possible are R1
to R12.
R15, R16 are the group fault inputs of the transistor
expansion unit (see also Monitoring Short-circuit/
Overload on page 187).

The outputs are processed as relay coils or contacts
like the outputs in the basic unit. The output relays
are S1 to S8.
EASY618-..-RE provides the outputs S1 to S6.
The other outputs S7, S8 can be used as
markers.

How is an expansion unit recognised?
When at least one R contact or S contact/coil is usedin the circuit diagram, the basic unit assumes that an
expansion unit is connected.

The input and output data of the expansion units istransferred serially in both directions. Take into
account the modified reaction times of the inputs andoutputs of the expansion units:

Expanding EASY600
Input and output reaction times of expansion

The debounce setting has no effect on the expansion
unit.
Transfer times for input and output signals:
Local expansion
Time for inputs R1 to R12:30 ms + 1 cycle
Time for outputs S1 to S6 (S8):15 ms + 1 cycle time
Remote expansion
Time for inputs R1 to R12:80 ms + 1 cycle
Time for outputs S1 to S6 (S8):40 ms + 1 cycle time

Function monitoring of expansion units
If the power supply of the expansion unit is notpresent, no connection can be established between
it and the 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 theoutputs S1 to S8 are transferred to the expansion
unit.

08/00 AWB2528-1304-GB

Warning
Ensure the continuous monitoring of the “easy”
expansion in order to prevent switching faults inmachines or systems.
The status of the internal input I14 of the basic unit
indicates the status of the expansion unit:
I14 = 0:I14 = 1:

Expansion unit is functional
Expansion unit is not functional

191

Inside “easy”
ExamplePower can be applied to the expansion unit later thanthe basic unit. This therefore means that the basic
unit is switched to Run with the expansion unit
missing. The “easy” circuit diagram below detects if
the expansion unit is operational or not.
I14-m1----Ä:8---------SM1
I14--------Ä:8

I1uI2----ÄQ1
Q1k

As long as I14 is 1, the remaining circuit diagram isskipped. If I14 is 0, the circuit diagram is processed.
If the expansion unit drops out for any reason, thecircuit diagram is skipped. M1 detects whether thecircuit diagram was processed for at least one cycle
after the power supply is switched on. If the circuit
diagram is skipped, all the outputs retain theirprevious state. The next example should be used if
this is not desired.

Glossary

Analog input

The DC versions of “easy” have analog inputs I7 andI8. The input voltage range is 0 V to 10 V. Input data
is evaluated by built-in analog comparator function
relays.

Circuit connections

Each line in the circuit diagram display is a circuit
connnection (EASY412: 41 circuit connections,
EASY600: 121 circuit connections).

Circuit diagram
symbols

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

Connect mode

Connect mode is used to wire up the circuit elements
in your “easy” circuit diagram.

Contact behaviour

The contact behaviour of any circuit element can be
defined as either a break contact or a make contact.
Break contact elements are identified by a line on topof the identifier (Exception: Jump).

Entry mode

Entry mode is used to input or modify values whencreating circuit diagrams or setting parameters, forexample.

Function relays

Function relays are provided for more complex
switching tasks. “easy” features the following typesof relay:213

Timing relays
Time switches
Counters
Analog comparators
Text marker relays

Impulse relay

An impulse relay is a relay which changes its
switching state and stays changed (latched) when avoltage is applied to the relay coil for a short time.

Input

The inputs are used to connect up external contacts.
In the circuit diagram, inputs are evaluated via
contacts I1 to I12 and R1 to R12.
“easy” 24 V DC can also receive analog data via
inputs I7 and I8.

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 andits associated “easy” settings.

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. Your data on the memory card will be

08/00 AWB2528-1304-GB

The EASY-SOFT PC software allows you to control“easy” from your PC which is connected using the“easy-PC-CAB” cable.

Glossaryretained, even if the power supply fails or is switchedoff.
The memory card is inserted into the interface slot on
the “easy” device.

Operating buttons“easy” has eight operating buttons. These are used
to select menu functions and create circuit diagrams.
The large round button in the middle is used to movethe cursor.

08/00 AWB2528-1304-GB

DEL, ALT, ESC and OK all perform additional
functions.

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

OutputYou can connect various loads to the four “easy”
outputs, such as 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 (Q6).

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 relay
contacts of P buttons are connected up in the circuit
diagram.

Parameters

Parameters enable the user to set the behaviour of afunction relay. Possible values include switchingtimes or counter setpoints. They are set in theparameter display.

Glossary
Power supply“easy”-AC is powered by AC voltage at 115 to 240 V
AC, 50/60 Hz. The terminals are labelled “L” and “N”.
“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 threeterminals on the input side.

Remote expansion

I/O expansion with the expansion unit (e.g.
EASY620-DC-TE) installed up to 30 m away from thebasic unit. The EASY200-EASY coupling unit is fitted
to the basic unit. The input and output data is
exchanged between expansion and basic unit via a
two-wire cable.

Retention

Retentive data is kept even after the “easy” power
supply is switched off.
The following data is retentive:“easy” circuit diagram
