1INTRODUCTION TO THE PROFIBUS DP PROTOCOL
A general overview of Profibus DP protocol, describing the main characteristics and functions, are presented
next.
1.1 PROFIBUS DP NETWORK
The term Profibus is used to describe a digital communication system that can be used in several application
areas. It is an open and standardized system, defined by the IEC 61158 and IEC 61784 standards, which
comprises from the used physical medium to data profiles for certain sets of equipments. In this system, the DP
communication protocol was developed with the purpose of allowing a fast, cyclic and deterministic
communication between masters and slaves.
Among the several communication technologies that can be used in this system, the Profibus DP technology
describes a solution that, typically, is composed by the DP protocol, RS485 transmission medium and
application profiles, used mainly in applications and equipments with emphasis in manufacturing automation.
Nowadays, there is an organization named Profibus International, responsible for keeping, updating and
publishing the Profibus technology among users and members. More information regarding the technology, as
well as the complete protocol specification can be obtained with this organization or with one of the
regional associations or competence centers associated to the Profibus International.
1.2 PROFIBUS DP PROTOCOL VERSIONS
The Profibus DP protocol defines a series of functions for exchanging data between master and slave. The set
of functions can be divided in different functional levels, in the following versions:

DP-V0
: It is the first version of the protocol, which mainly defines functions to perform cyclic data exchange
between master and slave.

DP-V1
: It is an extension of the functions defined in the first version; it defines particularly how to perform
the exchange of acyclic data between master and slave, besides the cyclic data.

DP-V2
: It defines a set of advanced functions such as communication between slaves and isochronous
communication mode.
The CFW500 frequency inverter supports the services of the DP-V0 and DP-V1 versions.
1.3 DEVICE TYPES IN A PROFIBUS DP NETWORK
Three different types of equipment are specified in a Profibus network:

Slaves
: They are passive stations in the network, which only answer to the requests made by the master.

Class 1 Master
: It is responsible for the cyclic data exchange. Typically represented by the PLC, or process
or plant control software.

Class 2 Master
: It allows the communication in the Profibus DP network through acyclic messages.
Typically represented by an engineering or configuration tool used for network commissioning or
maintenance.
The CFW500 frequency inverter operates as a slave in the Profibus DP network.
1.4 PHYSICAL LAYER
There are different network transmission types to allow communication in a Profibus network, each one with
suitable features according to the demands of different application types. The main transmission modes are:

RS485:
this is the most used transmission type for Profibus network. It provides high transmission rates,
simple installation and low cost.

MBP:
this is specified mainly for applications in chemical and petrochemical industries, for communication
in safety areas. The transmission rate is defined at 31.25 kbit/s with the possibility of feeding the devices
from the communication bus.

Optical Fiber:
this is used mainly in applications where high electromagnetic interference immunity and/or
great distances connections are required.

The Profibus DP accessory of the CFW500 frequency inverter provides an RS485 interface for network
connection.
1.5 APPLICATION PROFILE – PROFIDRIVE
Complementary to the Profibus protocol specification, the PROFIdrive specification, elaborated and kept by the
Profibus International, basically describes a set of parameters and services common for the “drive” type
equipments in a Profibus network. The purpose of this specification is to facilitate the integration of drives in a
Profibus network.
The Profibus DP interface for CFW500 frequency inverter was developed in accordance with the PROFIdrive
specification. Thus, several of the parameters, communication words and data access services of the drive are
described in accordance with this specification.

2PROFIBUS DP COMMUNICATION ACCESSORY
The following Profibus DP accessory is needed in order to enable the device communication in a Profibus DP
network. Information about the installation of this module can be found in the guide that came with the
accessory.

2.3 INDICATIONS
The alarms, faults and status indications are done through the device HMI and parameters.
2.4 DIP SWITCHES
At each segment of the Profibus DP network, it is necessary to enable terminating resistors at both end points
of the main bus. For this purpose, the Profibus DP communication module has two DIP switches that can be
activated (both switches to the ON position) to enable the resistor. The DIP switches should not be activated if
the network connector already has the terminating resistors.

3INSTALLATION IN THE PROFIBUS DP NETWORK
The Profibus DP network, such as several industrial communication networks, for being many times applied in
aggressive environments with high exposure to electromagnetic interference, requires that certain precautions
be taken in order to guarantee a low communication error rate during its operation. Recommendations to
perform the product connection in this network are presented next.
3.1 BAUD RATES
The Profibus DP protocol defines several baud rates that can be used, from 9.6 kbit/s up to 12Mbit/s. The
maximum allowed transmission line length depends on the used baud rate, and this correlation is showed on
the table 3.1.
Table 3.1: Baud rate x segment length
Baud Rate

1000
500
400
1500

3000, 6000, 12000
100
All equipments in the network must use the same baud rate. The CFW500 Profibus DP interface has automatic
baud rate detection, according to what has been configured for the network master, and therefore it is not
necessary to configure this option.
It is possible to observe the baud rate detected by the board at the parameter P0963.
3.2 ADDRESSING
Every device in a Profibus DP network, master or slave, is identified through a network address. This address
must be different for each device.
The CFW500 Profibus DP address is configured through the parameter P0918.
3.3 CABLE
It is recommended that the installation be carried out with a type A cable, whose characteristics are described in
the table 3.2. The cable has a pair of wires that must be shielded and twisted, in order to guarantee higher
immunity against electromagnetic interference.

Capacitance
30 pf/m
Loop resistance

Wire cross section

3.4 CONNECTORS
Several connector types can be used for the network connection of the equipment, from simple screw
connectors up to very specific connector types for the Profibus network.
The connector used in the CFW500 Profibus DP accessory is presented at item 3.4.
3.5 CONNECTION TO THE NETWORK
The Profibus DP protocol, by using the RS-485 physical medium, allows the connection of up to 32 devices per
segment without the use of repeaters. By using repeaters, up to 126 addressable equipments can be
Phone: [phone] - Fax: [phone] - Web: www.ctiautomation.net - Email: [email protected]

connected to the network. Each repeater must also be included as a device connected to the segment, even
not occupying a network address.
It is recommended that the connection of all the devices present in the Profibus DP network be made coming
from the main bus. Generally, the Profibus network connector itself has an input and an output for the cable,
allowing the connection to be taken to the other network points. Derivations from the main bus are not
recommended, especially for baud rates higher or equal to 1.5Mbits/s.
Figure 3.1: Connection example in a Profibus DP network
The Profibus DP network cables must be laid separately (and far away if possible) from the power cables. All the
drives must be properly grounded, preferably at the same ground point. The Profibus cable shield must also be
grounded. The CFW500 Profibus board connector itself already has a connection with the protective ground
1
and, therefore, makes the connection of the shield to the ground when the Profibus cable is connected to the
drive. However a better connection, implemented by clamps that connect the shield to a ground point, is also
recommended.
3.6 TERMINATING RESISTOR
At each segment of the Profibus DP network, it is necessary to enable a terminating resistor at the end points of
the main bus. The use of specific Profibus network connectors with a switch to enable the resistor is
recommended, which must only be enabled (ON position) if the equipment is the first or the last element of the
segment. The DIP switches present in the communication module also can be used to enable the termination
resistors.
It is important to emphasize that in order to be possible to disconnect the element from the network without
impairing the bus, it becomes interesting the use of active terminations, which are elements that have only the
termination function. Therefore, any drive of the network can be disconnected from the bus without impairing
the termination.
3.7 GSD FILE
Each element of the Profibus DP network has an associated configuration file with the GSD extension. This file
describes the characteristics of each equipment and it is used by the Profibus DP network master configuration
tool. During the master configuration the GSD configuration file supplied with the equipment must be used.

It is necessary to connect the protective earth to the GND signal in the plug-module.

These parameters are used in the configuration of the command source for the CFW500 frequency inverter local
and remote situations. In order that the device be controlled through the Profibus DP interface, the options
‘CANopen/DeviceNet/Profibus DP’ available in these parameters, must be selected.
The detailed description of these parameters is found in the CFW500 programming manual.
P0313 – COMMUNICATION ERROR ACTION
Range: 0 = Inactive Default: 1
1 = Disable via Run/Stop

Table 4.1: P0313 options
Options
Description
0 = Inactive
No action is taken and the drive remains in the existing status.
1 = Disable via Run/Stop
A stop command with deceleration ramp is executed and the
motor stops according to the programmed deceleration ramp.
2 = Disable via General Enable
The drive is disabled by removing the General Enabling and the
motor coasts to stop.
3 = Change to Local
The drive commands change to Local.
4 = Change to Local keeping
commands and reference
The drive commands change to Local, but the status of the
enabling and speed reference commands received via network
are kept, providing that the drive has been programmed to use in
Local mode the commands via HMI, or 3-wire start/stop and
speed reference via either HMI or electronic potentiometer.
5 = Causes a Fault
Instead of an alarm, the communication error causes an drive
fault, so that a drive fault reset becomes necessary in order to
restore normal operation.
The following events are considered communication errors:
Profibus DP communication:
A138 alarm/F238 fault: command received to enter clear mode.
A139 alarm/F239 fault: device goes to
offline .
A140 alarm/F240 fault: Profibus DP interface access error.
The actions described in this parameter are executed by means of the automatic writing of the selected actions
in the respective bits of the interface control words. Therefore, in order that the commands written in this
parameter be effective, it is necessary that the device be programmed to be controlled via the used network
interface (with exception of option “Causes a Fault”, which blocks the equipment even if it is not controlled by
network). This programming is achieved by means of parameters P0220 to P0228.

P0681 – MOTOR SPEED IN 13 BITS
Range: - 32768 to 32767 Default: -
Properties: RO
Access groups via HMI: NET
Description:
It allows monitoring the motor speed. This word uses 13-bit resolution with signal to represent the motor rated
frequency (P0403):
P0681 = 0000h (0 decimal) →motor speed = 0
P0681 = 2000h (8192 decimal) →motor speed = rated frequency
Intermediate or higher speed values in rpm can be obtained by using this scale. E.g.60Hz rated frequency if the
value read is 2048 (0800h), then, to obtain the speed in Hz one must calculate:
8192 => 60 Hz
2048 => Frequency in Hz
Frequency in Hz = 60 ×2048
8192
Frequency in Hz = 30 Hz
Negative values in this parameter indicate that the motor is running in the reverse direction.

P0685 – PROFIBUS DP SPEED REFERENCE
Range: -32768 to 32767 Default: 0
Properties:-
Access groups via HMI: NET
Description:
It allows programming the motor speed reference via the Profibus DP interface. This parameter can only be
changed via CANopen/DeviceNet/Profibus DP interface. For the other sources (HMI, etc.) it behaves like a read-
only parameter.
Phone: [phone] - Fax: [phone] - Web: www.ctiautomation.net - Email: [email protected]

In order that the reference writtenin this parameter be used, it is necessary that the drive be programmed to
use the speed reference via CANopen/DeviceNet/Profibus DP. This programming is achieved by means of
parameters P0221 and P0222.
This word uses a 13-bit resolution with signal to represent the motor rated frequency (P0403).
P0685 = 0000h (0 decimal) →speed reference = 0
P0685 = 2000h (8192 decimal) →speed reference = rated frequency (P0403)
Intermediate or higher reference values can be programmed by using this scale. E.g.60Hz rated frequency, to
obtain a speed reference of 30 Hz one must calculate:
60 Hz => 8192
30 Hz => 13 bit reference
13 bit reference = 30
×
8192
60
13 bit reference = 4096
This parameter also accepts negative values to revert the motor speed direction. The reference speed direction,
however, depends also on the control word - P0684 - bit 2 setting:
Bit 2 = 1 and P0685 > 0: reference for forward direction

P0696 – VALUE 1 FOR ANALOG OUTPUTS
P0697 – VALUE 2 FOR ANALOG OUTPUTS
P0698 – VALUE 3 FOR ANALOG OUTPUTS
Range: -32768 to 32767 Default: 0
Properties: -
Access groups via HMI: NET
Description:
They allow the control of the analog outputs by means of network interfaces (Serial, CAN, etc.). These
parameters cannot be changed via HMI.
The value written in these parameters is used as the analog output value, providing that the function for the
desired analog output be programmed for “P0696 / P0697 / P0698 value”, at the parameters P0251, P0254,
P0257.
The value must be written in a 15-bit scale (7FFFh = 32767)
2
to represent 100 % of the output desired
value, i.e.:
P0696 = 0000h (0 decimal) →analog output value = 0 %
P0696 = 7FFFh (32767 decimal) →analog output value = 100 %
The showed example was for P0696, but the same scale is also used for the parameters P0697 / P0698. For
instance, to control the analog output 1 via serial, the following programming must be done:
Choose a parameter from P0696, P0697, P0698 to be the value used by the analog output 1. For this
example, we are going to select P0696.
Program the option “P0696 value” as the function for the analog output 1 in P0254.
Using the network interface, write in P0696 the desired value for the analog output 1, between 0 and 100
%, according to the parameter scale.
NOTE!
For CFW500 frequency inverter, the analog output 3 represents the frequency output (FO).

P0741 – PROFIBUS DATA PROFILE
Range: 0 = PROFIdrive Default:1
1 = Manufacturer
Properties:DP
Access groups via HMI: NET
Description:
It allows selecting the data profile for the control, speed reference, status and motor speed words during the I/O
data exchange with the network master.
Table 4.6: Parameter P0741 options
Option
Description
0 = PROFIdrive
The control, status, speed reference and motor speed words have
values and functions according to what is described by the
PROFIdrive specification. The description of each word is done in
the following parameters:
P0967: PROFIdrive control word.
P0968: PROFIdrive status word.
The speed reference and motor speed words for this profile are
described next.
1 = Manufacturer
The control, status, speed reference and motor speed words have
values and functions specific for CFW500 frequency inverter. The
description of each word is done in the following parameters:
P0680: Status word
P0681: Motor Speed in 13 Bits
P0684: Control word
P0685: Speed reference.
Phone: [phone] - Fax: [phone] - Web: www.ctiautomation.net - Email: [email protected]

Speed for PROFIdrive profile:
If the used profile is the PROFIdrive, both the speed reference and the motor speed must be indicated as a
value proportional to the drive maximum speed, programmed through P0134:
Value via Profibus = 0000h (0 decimal) →Speed = 0 Hz
Value via Profibus = 4000h (16384 decimal) →Speed = maximum speed (P0134)
Intermediary speed values in rpm can be obtained using this scale. For instance, if P0134 is programmed for 30
Hz and the motor speed value read via Profibus is 2048 (0800 h), in order to obtain the value in Hz the following
calculation must be done:
16384 => 30 Hz
2048 => speed in Hz
Speed in Hz = 30
×
2048
16384
Speed in Hz = 3.75 Hz
The same calculation applies for the transmission of speed reference values. Negative speed values indicate
reverse speed direction.
NOTE!
For the reference writing in the drive
, the values are converted and written in the parameter
P0685.
The reference writing does also depend on the bit 6 of the PROFIdrive control word (P0967).

If this parameter is changed, the slave will assume the new configuration only when there is no
cyclic communication with the master.
P0742 – PROFIBUS READING #3
P0743 – PROFIBUS READING #4
P0744 – PROFIBUS READING #5
P0745 – PROFIBUS READING #6
P0746 – PROFIBUS READING #7
Range: 0 to 1199 Default:0 (disabled)
Properties:DP
Access groups via HMI: NET
Description:
These parameters allow programming the content of the input words 3 a 83 to 10 (input: drive sends to the
master). By using these parameters it is possible to program the number of another parameter whose content
must be made available at the network master input area.
If, for instance, one wants to read from the CFW500 frequency inverter the motor current in Amps, one must
program the value 3 in one of these parameters, because the parameter P0003 is the one that contains this
information. It is worthwhile to remind that the value read from anyparameter is represented with a 16 bit word.
Even if the parameter has decimal resolution, the value is transmitted without the indication of the decimal
places. E.g., if the parameter P0003 has the value 4.7A, the value supplied via the network will be 47.
These parameters are used only if the equipment is programmed at the parameter P0922 to use the options 3
to 8 (configuration telegrams 103 to 108). Up to 8 words to be read by the network master can be made
available, according to the selected option.
The first two input words are fixed and represent the status and the motor speed.
Phone: [phone] - Fax: [phone] - Web: www.ctiautomation.net - Email: [email protected]

NOTE!
The value 0 (zero) disables the reading in the word.
The number of input words, however, keeps the
same as programmed at P0922.

P0754 – PROFIBUS WRITING #7
P0755 – PROFIBUS WRITING #8
Range: 0 to 1199 Default:0 (disabled)
Properties: DP
Access groups via HMI: NET
Description:
These parameters allow programming the content of the output words 3 a 8 (output: master sends to the drive).
Using these parameters, it is possible to program the number of another parameter whose content must be
made available at the network master output area.
If, for instance, one wants to write the acceleration ramp value in the CFW500 frequency inverter, one must
program the value 100 in one of these parameters, because the parameter P0100 is the one where this
information is programmed. It is worthwhile to remind that the value written in any parameter is represented with
a 16 bit word. Even if the parameter has decimal resolution, the value is transmitted without the indication of the
decimal places. E.g., if one wishes to program the parameter P0100 with the value 5.0s, the value programmed
via the network must be 50.
These parameters are used only if the equipment is programmed at the parameter P0922 to use the options 3
to 8 (configuration telegrams 103 to 108). Up to 8 words to be written by the network master can be made
available, according to the selected option.
The first two output words are fixed and represent the control and the speed reference.
NOTE!

The value 0 (zero) disables the writing in the word. The number of input words, however, keeps
the same as programmed at P0922.
The written parameters using these words are not saved in non-volatile memory. Thus, if the
equipment is turned off and on again, these parameters will return to their original value.

8 = Telegram 108 (8 I/O words)
Properties: DP
Access groups via HMI: NET
Description:
It allows selecting which configuration telegram is used by the drive during the Profibus DP network initialization.
This telegram defines the format and quantity of input/output data exchanged with the network master.
During the network master configuration, by using the GSD file, it is possible to select the desired data module
for the exchange of cyclic data between the master and the slave. It is possible to exchange from 2 to 8
input/output (I/O) words (16 bits each), depending on the selected option. The value programmed in this
parameter must coincide with the module selected by the network master configuration tool.
The content of the first two input/output words is pre-defined. The other words are programmable through the
