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
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
Maximum distances/bus
cable lengths
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is obsolete.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

This value sets the EZ/EZD status from STOP to RUN. It is
only interpreted as a command and therefore does not permit
an additional transfer of data. The index value 14 must be

used in this situation.
Value 44 = 01000100 :

bin
This value sets the EZ/EZD status from RUN to STOP. It is
also used only as command and it therefore works in the same
way as the RUN command.

Note on using the 1 byte modules
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.

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.

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.

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.

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:
J
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.

Always note the following when working with function blocks:
• The relevant data is transferred in Intel format. In other
words, the first byte is the low byte (Byte 5) and the last byte
(byte 8) the high byte.
• The maximum data length is 4 bytes. All values must be
transferred in hexadecimal format.
• All 32-bit values are treated as signed values. When
transferring 32-bit values, ensure that the appropriate value
range is suitable for long integers, i.e. signed.
