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 DeviceNet connection
In this manual the exchange of data between the circuit-
breaker NZM with DMI and a DeviceNet system is described.
The interface that is used is the EASY222-DN communication
module, which provides several functions specifically for
operation with the DMI.
The description in this manual is restricted to the functions
that are typical for power circuit-breakers. Detailed
information can be found in asection “Additional
manuals”, page 3.

• Reading of the NZM status and DMI inputs via
I/O messages
asection “Read NZM status and DMI inputs”, page 9,
• Setting the DMI outputs via I/O messages

Commissioning the
DeviceNet interface
Detailed information concerning the installation and design
of the EASY222-DN can be found in aAWB2528-1427GB,
sections 1 and 2.
The following steps are necessary for commissioning of the
EASY222-DN interface:
XConnect the EASY222-DN via the “EASY-Link” connector
to the DMI (basic unit).
To plug the connector into the DMI, push up the cover flap
on the right side of the housing.
XConnect the 24 V DC power supply for the EASY222-DN
(Do not switch it on just yet!).
XConnect the 5-pole DeviceNet connector to the
EASY222-DN.
The pin assignments can be found in
aAWB2528-1427GB.
XCheck that all connections are correct.
XSwitch on the power supply for the DMI and the interface.
XSet the required bus node address via the display and the
keypad on the DMI.
The procedure can be found in aAWB1230-1441GB.
XConfigure the DeviceNet system with the EASY222-DN as
a new station.
XStart the DeviceNet system.
After these steps the EASY222-DN interface should be in the
“not online” (MS-LED lights continuously green, NS-LED is
off) or “online without active communication connection“
(MS-LED lights continuously green, NS-LED flashes green)
state.

quick analysis of the problem can be found in a

access the most important status data of the circuit-breaker
or to change the outputs of the DMI.
Read NZM status and DMI inputs
The data is output via polled I/O messages.
3 data bytes are transmitted, which are arranged as follows:

hBefore data can be read or set using I/O messages an
active communication connection must be established to
the DeviceNet interface. Detailed information can be
found in aAWB2528-1427GB, Section “Management

Outputs 0 to 3 of the DMI can be written according to the
motor starter function that has been selected.
Outputs 4 and 5 can either be set as freely addressable
(Remote operator mode = 1), or controlled via “Actuate
circuit-breaker” (Remote operator mode = 0).
Data access via explicit messages
Explicit messages serve reading or writing access to all
supported data objects such as
• Management objects,
• Connection objects,
• Application-specific objects.
The management objects (identity object and message
router object) and the connection objects (DeviceNet object
and connection object) incorporate general services, which
are necessary for operation of the device on the DeviceNet.
The application-specific objects (assembly object and easy
object) enable application-specific preparation of the data.
For communication with the circuit-breaker or with the DMI,
a portion of the easy object is used.

In the following only the use of the easy object for scanning
and entering the NZM and DMI data is described.
All data of the circuit-breaker or the DMI can be accessed or
modified by use of the easy object. The easy object with
Class ID: 64hex, Instance ID 01 and Service Code: 32hex is
used.
The attribute defines if it is a read access on one or two bytes
or a write access on one byte. In the data field the details of
the address to which the attribute refers (achapter 2,
page 21), and if applicable, the byte to be written, are
contained.
The following table makes the association clear.

Write data
Using the easy object and the command code described in
atable 1, the DeviceNet telegram can write a byte to the
EASY222-DN. The telegram has the following content:
The EASY222-DN responds with the value “00” in the
telegram data fields.
Read data
Using the easy object and the command code described in
atable 1, the DeviceNet telegram can request one or two
bytes from the EASY222-DN. The telegram has the following
content:
The EASY222-DN responds with a telegram, which feeds
back the used address in the first two data fields, followed
by the data actually requested (1 or 2 bytes, depending on
the attribute).
