Danger!
Dangerous electrical voltage!

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.

• 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, 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 operating state in the event of
a fault or malfunction (for example, by means of separate limit
switches, mechanical interlocks etc.).

1 Device application

The controllers of the EC4-200 series are programmable switching
and control devices. They can be used in domestic applications,
machine building and plant construction. An EC4-200 controller
can be used as a stand-alone controller or connected to remote
input/output devices via the CANopen interface. This interface also
allows you to communicate with other PLCs (with a CANopen
interface).

The EC4P-222-... controller types have an additional Ethernet
interface.

From version 2.0 of the operating system the controllers have the
following features:

• Connection of expansion devices/controllers via easyLink

• Connection of the MFD-CP4 multi-function display via the
multi-function interface

• Transparent mode via the multi-function interface

• Direct access to local I/O and the high-speed counters

• Integration in the easyNet network via the easyNet/
CAN interface

Controllers from version 2.10 can be connected to the ASI,
PROFIBUS-DP, CAN or DeviceNet networks with suitable network
interfaces.

The controller is programmed with the easySoft CoDeSys
programming software. This software should be installed on a
standard PC with the Windows NT, 2000 or XP operating system.
Further information on the software is provided in the manual for
the programming software (MN05010003Z-EN; previously
AWB2700-1437GB).

This software provides you with a simple entry in the IEC
programming languages such as:

• Instruction List (IL)

• Function Block Diagram (FBD)

• Ladder Diagram (LD)

• Structured Text (ST)

• Sequential Function Chart (SFC).

Inputs I1, I2, I3, I4 can be used for:

• generating interrupts (inputs I1, I2, I3, I4)

• controlling high-speed counters such as:
– 16 or 32-bit counters, for counting pulses (I1, I2),

up/down counting

– Incremental counters, 32-bit, for processing the signals of an

incremental encoder (I1, I2, I3, I4).

The function is selected in the PLC configuration. However, several
functions cannot be used at the same time.

Example: If you are using input I1 for a high-speed counter (16­bit), I2 can be used for another high-speed counter (16-bit) but not
for generating an interrupt. Inputs I3 and I4 likewise cannot be
used for generating an interrupt.

Connection description

a figure 22 on page 23.

Function and cursor buttons as inputs

The front plate of the device is provided with the function buttons
DEL, ALT, ESC, OK which are arranged around the rocker switch.
The rocker switch is divided into 4 sections with the cursor button
designations P1 to P4. The function and cursor buttons are
represented in the PLC configuration as inputs. These inputs are
scanned in the program according to general syntax rules. Only
one button can be actuated at a time, otherwise uncontrolled
states may occur when these buttons are scanned.

Figure 4: Function buttons and rocker switch with cursor buttons

P1, P2, P3, P4

Diagnostics inputs

The inputs I13, I14, I15, I16 provide you with additional
information:

Input Function

I13 No function

I14 Expansion device via easyLink (not yet active in the

operating system version 1.x):
0: ok, 1: not ok

I15 Outputs Q1, Q2, Q3, Q4:

0: No short-circuit, 1: Short-circuit

I16 Outputs Q5, Q6, Q7, Q8:

0: No short-circuit, toggle: Short-circuit

The inputs can be scanned in the program with symbolic operands.

Inputs for high-speed counters

You can choose between several different functions:

•1 x 32-bit counter, for counting pulses (up/down)

•2 x 16-bit counters, for counting pulses (up/down); the count
direction (up/down) can be set via the DIRECTION operand in
the program.

•1 x incremental value counter, 32-bit, for processing the
signals of an incremental encoder; the count direction is set by
the edge sequence of the encoder.

Figure 5: Inputs of the rocker and function buttons

The GetDisplayInfo function block from the EC_Visu2.lib library
enables you to control the scanning of the buttons according to
the active menu on the controller,

a section

“EC_Visu.lib/EC_Visu2.lib library”, page 62.

You can select the counter type in the PLC configuration.

The function of the high-speed counter requires the setting of
inputs and the scanning of outputs in a POU, e.g. PLC_PRG.
This POU must not be called by an interrupt generated by a
counter.

For further information see section “High-speed counters
(Counter)”, page 45.

the user program via functions from the SysLibRTC library.
The functions are described in the PDF file „SysLibRTC“.
After the software is installed, this file can be opened via
<Programs
Documentation

l Moeller Software l easySoft CoDeSys l

l Automation Manuals>.

You can read and set with the browser commands “getrtc” and
“setrtc” respectively. More information is provided in section
“setrtc” on page 60.

During a voltage loss the clock is backed up for at least 72 hours.

Interfaces

Programming interface for connection to a PC

Communication between PLC and the programming device is
implemented via the programming interface, consisting of an RJ45
connector.

The connector is provided with an RS232 interface and an
additional Ethernet interface on the EC4P- 222-... PLC types for
programming.

Splitting the RS232/Ethernet interface

Using a cable splitter XT-RJ45-ETH-RS232 you can communicate
simultaneously via the RS232 and the Ethernet interface.
The connection between the PLC and the cable splitter is
established using the EASY-NT-30/80/130 cable. The pin
assignment of the RS232 and Ethernet connector socket of the
cable splitter corresponds with the pin assignment of the
programming interface as shown in table 5.

Transparent mode

In order to establish a point-to-point connection (without
handshake cables) to another device, switch the RS232 interface
to Transparent mode using the functions from the library
EC_SysLibCom.lib. In Transparent mode, the interface is
addressed as COM1.

a chapter “RS232 interface in Transparent mode”, page 73.

Multi-function interface (MFI)

The controller can alternatively communicate with the following
devices via this interface:

•Memory card
The memory card should be fitted in an adapter which is then fitted
on this slot.

• MFD-CP4 multi-function display
The MFD is a display with HMI features that is mounted away from
the PLC. It displays the content of the PLC display. Integrated
buttons enable you to send signals to the controller and control
the processing of the program. The MFD can be mounted in a
control cabinet door up to 5 m away from the controller.
The devices are connected with the cable MFD-CP4-800-CAB5.

• Terminal/printer
A terminal enables you to display and enter alphanumeric
characters. A printer can also be used to output data. The terminal
is connected to the PLC via an RS232 interface using the EASY800­PC-CAB cable. The cable with the components for adapting the
PLC signals must be provided with a separate power supply from
the terminal. The signals and pin assignment of the interface must
be implemented in compliance with the RS232 specification.

Setup

CAN/easyNet interfaces

The PLC is provided with a CAN/easyNET interface with two slots
that are internally connected via terminals.

10/10 MN05003003Z-EN

Figure 8: CAN/easyNet interfaces

CANopen

The CAN interface is designed as a CANopen interface in
compliance with the CIA specification DS301V4.0. The PLC can be
operated both as an NMT master as well as a CAN device on CAN
networks. When used as a CAN device the PLC requires an address
(= Node ID) for identification on the bus. Permissible node IDs are
1, … ,127. The configuration of the master and the device is
carried out in the PLC configuration.

4 Mounting

Install the PLC in a control cabinet, a service distribution board or
in an enclosure so that the power supply terminals and other
terminals are protected against direct contact during operation.

The PLC can be installed vertically or horizontally on a top-hat rail
in compliance with IEC/EN 60715 or on a mounting plate using
fixing brackets.

Ensure that the terminal side has a clearance of at least 3 cm from
the wall and from neighbouring devices in order to simplify wiring.

Mounting on top-hat rail

X Place the device diagonally on the upper lip of the top-hat rail.

Press down lightly on both the device and the top-hat rail until
the unit snaps over the lower edge of the top-hat rail. The
spring mechanism should ensure that the device snaps into
position automatically.

X Check that the device is seated firmly.

Figure 11: Mounting on top-hat rail

.

The device is mounted vertically on a top-hat rail in the same way.

Mounting on mounting plate

Fixing brackets that can be inserted on the rear of the device are
required for screw mounting. The fixing brackets are available as
an accessory.

Cable protection

Protect the supply cables with a miniature circuit-breaker or at
least a 1A (slow blow) fuse (F1).

Connecting digital inputs

Use input terminals I3 to I4 to connect pushbutton actuators,
switches or 1 or 12-wire proximity switches. Given the high
residual current, do not use 2-wire proximity switches.

Caution!

i

Observe the following when laying and connecting analog
cables:

this, i.e. no Reed relay contacts, no proximity switches.

X Use screened, twisted pair conductors, to stop interference of

the analogue signals.

X With short cable lengths, ground the shield at both ends using

a large contact area. If the cable length is more than around
30 m, 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 earth the
conductor on one side.

X Don‘t lay the signal conductor parallel to the power conductor.
X Connect inductive loads that you are switching via the outputs

to a separate power supply or use a suppressor circuit for
motors and valves. If the controller is run with motors, solenoid
valves or contactors via the same power supply, the switching
may cause interference on the analog input signals.

The following circuits show examples of analog measuring
applications.

Parallel connection:
Up to four outputs can be connected in parallel in order to increase
the power. This enables a maximum output current of 2 A.

Caution!

i

Please note the following when switching off inductive
loads:
Suppressed inductive loads cause less interference in the
entire electrical system. It is generally recommended to
connect the suppressor as close as possible to the
inductance.

Caution!

i

Only outputs of the same group (Q1 to Q4 or Q5 to Q8)
can be connected in parallel; e.g. Q1 and Q3 or Q5, Q7
and Q8. Outputs connected in parallel must be switched
at the same time.

If inductive loads are not suppressed, the following must be
observed: Several inductive loads should not be switched off

Figure 26: Inductive load with suppressor circuit

Behaviour with short-circuit/overload

A transistor output will switch off in the event of a short-circuit or
overload. The output will switch back on up to the maximum
temperature after a cooling time that depends on the ambient
temperature and the current level. If the fault continues, the
output will switch off and on until the fault is rectified or the power
supply is 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 (
