Warning!
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.

• Short circuit to earth.

• Cover or enclose neighboring 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 equalization. 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.).

Connecting PROFIBUS-DP

Connecting PROFIBUS-DP Use a 9-pole SUB-D plug to connect the PROFIBUS-DP

interface to the PROFIBUS-DP fieldbus. For this use the
special PROFIBUS-DP plug and the special PROFIBUS-DP
cable available from the Eaton range of accessories. The type
of cable used determines the permissible maximum bus
length and the transfer rate.

Installation

Bus terminating resistors The first and last station in a bus segment must be connected

to the bus with the bus terminating resistor switched on. The
bus terminating resistor is switched externally. This external
switch function can either be implemented as a separate bus
terminating resistor or with a special Sub-D plug with an
integrated bus termination.

Eaton's PROFIBUS-DP data plug enables both bus
terminating resistors to be switched on and off.

EMC wiring Electromagnetic interference may have adverse effects on the

communication fieldbus. This can be minimized in advance by
taking suitable EMC measures. These include:

• System design in accordance with EMC requirements,

• EMC cabling and

• Measures that prevent the occurrence of large potential
differences,

• Correct installation of the PROFIBUS system (cable,
connection of bus connector,...).

The effects of electromagnetic interference can be
significantly reduced by fitting the shield. The following two
figures illustrate how to fit the shield.

Installation

Transfer rates – automatic
baud rate detection

Maximum distances/bus cable lengths

The EZ204-DP module automatically detects the baud rate
used in the communication network after it is switched on.
However, this requires that at least one station sends valid
telegrams in the network.

The EZ204-DP module detects the transfer rate automatically.
The following transfer rates are supported:

• 9.6 Kbit/s to 12000 Kbit/s

Two types of bus cable are specified in IEC 61158. Cable type
B should no longer be used with new applications because it
is obsolete. Cable type A allows all transfer rates up to
12000 Kbit/s to be used. Cables for burial in the ground,
festoon suspension and drum cables are also available.

The cable parameters are as follows:

Parameters Cable type A

Surge impedance in Ω 135 ... 165 at 3 ... 20 MHz
Effective capacitance (pF/m) < 30
Loop resistance (Ω/km)
Core diameter (mm) > 0.64
Core cross-section (mm2) > 0.34

< 110

The cable parameters specified allow the following bus
segment lengths.

3 Device Operation

Initial power up XBefore you switch on the device, verify that it is properly

connected to the power supply, to the bus connector and to
the basic unit.

XSwitch on the power supply to the basic unit and the

PROFIBUS-DP expansion unit.

The Power LED of the EZ204-DP is lit. The BUS LED is off (no
communication via PROFIBUS-DP).

The GW message (intelligent station connected) is displayed
on the basic unit.

For more information visit: www.EatonElectrical.com 25MN05013001E

Valid data is only transferred via PROFIBUS-DP to the
basic unit if the GW is displayed statically.

If the PROFIBUS-DP unit is factory set, the station address of
the PROFIBUS-DP station must be set.

Device Operation

Setting the PROFIBUS-DP station address

Every PROFIBUS-DP station requires an unambiguous
address in the PROFIBUS-DP structure. There are two ways
of setting the PROFIBUS-DP addresses on the EZ204-DP:

• Using the integrated display and keypad on the EZ or EZD
basic unit

• Using EZSoft on the PC.

Address range: 001 to 126

Setting the address on the basic unit with a display

Requirements:

• The basic unit (EZ700, EZ800 or EZD) and the EZ204-DP
expansion unit must be fed with power.

• The basic unit has been unlocked (no password activated).

• The basic unit has a valid operating system version
(J page 15).

• The basic unit must be in STOP mode.

• The EZ204-DP is not communicating with the PROFIBUS­DP master (Bus LED is off).

The 1 byte modules are not available in all device
combinations. If any problems occur in handling, first check
the state of the GW message in the status display of the basic
unit:

GW static: The 1-byte mode can be used
GW flashing: Check the device version of the EZ204-

DP and the basic unit. If these are valid,
check the configuration in the PROFIBUS
network and the Configurator.

6 Control commands for EZ700

Data exchange procedure The “Control commands 9 bytes” module allows extended

data exchange of the EZ700 on the PROFIBUS-DP
communication bus. This allows you to transfer services from
the following areas:

• Read/write image date and time (Page 45)

• Read/write image data (Page 49) and

• Read/write function block data (Page 72).
A data exchange procedure is required in order to ensure the

safe exchange of data via PROFIBUS-DP from master to
slave and vice versa.

Attention!

While a control command is being executed, the input and
output data will remain in the state before the control
command was called. Only after the “Control commands”
data exchange has been completed, will the I/O data be
refreshed.

Caution!

Only those values specified for the command code should
be used.

Check the values that you write in order to avoid
malfunctions.

Requirement:
The “Control commands 9 byte” module must have been
selected.

For more information visit: www.EatonElectrical.com 43MN05013001E

Control commands for EZ700

The master initiates the data exchange of the control
commands and the addressed slave responds.

During communication 9 data bytes (byte 0 = toggle byte,
bytes 1 to 8 information bytes) are sent via PROFIBUS.

The basic telegram structure is shown in the following
diagram.

Byte 0 Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Byte 7 Byte 8

Byte 0 – Toggle byte

Byte 0 is used to activate the sending of a control command

Procedure

XTo send a command, bit 7 must be toggled, i.e. set either

from 1 to 0 or from 0 to 1.

XThen poll the toggle bit for the coupling modules response

until it has the same status as the toggle bit sent. This status
indicates to the master that the response to the sent
command is valid.

XDo not send a new command until you have received a

response (changing of the toggle bit), otherwise the
response of the previous command will be overwritten
before it can be read.

Data exchange procedure

J

J

In order to use input/output data and control commands
simultaneously:

Only after the “Control commands” data exchange has
been completed, will the I/O data be refreshed.

All specified commands and parameters must be
transferred in hexadecimal format.

The following tables show the different control commands
possible. These essential control commands fall into three
essential categories – real-time clock, image and function
blocks.

Please also note the relevant description of the real-time
clock provided in the EZ500/700 manual (MN05013003E).

When writing to image data, it must be remembered that an
image (e.g. inputs, outputs,... ) used in the EZ700/EZ800/EZD
program is also written cyclically by the actual program. The
only image data that is unchanged is the data that is not used
in the program and is therefore not overwritten in the program
cycle. This operating principle also means that an image
written via EZ-LINK, such as output data is only then output at
the physical outputs of the EZ700/EZ800/EZD when the
control relay is in Run mode.

7 EZ800/EZD Control Commands

Data exchange procedure The Control commands 9 bytes module allows extended data

exchange of the EZ800 and the EZD on the PROFIBUS-DP
communication bus. This allows you to transfer services from
the following areas:

• Read/write date and time (Page 95)

• Read/write image data (Page 99) and

• Read/write function block data (Page 120).
A data exchange procedure is required in order to ensure the

safe exchange of data via PROFIBUS-DP from master to
slave and vice versa.

Attention!

While a control command is being executed, the input and
output data will remain in the state before the control
command was called. Only after the “Control commands”
data exchange has been completed, will the I/O data be
refreshed.

Caution!

Only those values specified for the command code should
be used.

Check the values that you write in order to avoid
malfunctions.

Requirement:
The “Control commands 9 byte” module must have been
selected.

The master initiates the data exchange of the control
commands and the addressed slave responds.

During communication 9 data bytes (byte 0 = toggle byte,
bytes 1 to 8 information bytes) are sent via PROFIBUS.

The basic telegram structure is shown in the following
diagram.

Procedure

XTo send a command, bit 7 must be toggled, i.e. set either

from 1 to 0 or from 0 to 1.

XThen poll the toggle bit for the coupling modules response

until it has the same status as the toggle bit sent. This status
indicates to the master that the response to the sent
command is valid.

XDo not send a new command until you have received a

response (changing of the toggle bit), otherwise the
response of the previous command will be overwritten
before it can be read.

In order to use input/output data and control commands
simultaneously:

Only after the “Control commands” data exchange has
been completed, will the I/O data be refreshed.

All specified commands and parameters must be
transferred in hexadecimal format.

The following tables show the different control commands
possible. These essential control commands fall into three
essential categories – real-time clock, image and function
blocks.
