actual products have been checked for conformity to EMC standards. (See
the following note.) Whether the products conform to the standards in the system used by the customer, however, must be checked by the customer.
EMC-related performance of OMRON Units complying with EC Directives will
vary depending on the configuration, wiring, and other conditions of the equipment or control panel in which OMRON devices are installed. The customer
must, therefore, perform final checks to confirm that units and the overall system conforms to EMC standards.

Units that meet EC directives also meet the common emission standard
(EN50081-2). The measures necessary to ensure that the standard is met will

Overview of PROFIBUS
Section 1-1
1-1 Overview of PROFIBUS
1-1-1 Introduction
Standard EN50170 PROFIBUS (PROcess FIeldBUS) is an open fieldbus standard for a wide
range of applications in manufacturing, processing and building automation.
The Standard, EN 50170 (the Euronorm for field communications), to which
PROFIBUS adheres, guarantees vendor independence and transparency of
operation. It enables devices of various manufacturers to intercommunicate
without having to make any special interface adaptations.
The PROFIBUS family comprises three mutually compatible versions: PROFIBUS FMS, PROFIBUS DP and PROFIBUS PA.
PROFIBUS FMS FMS means Fieldbus Message Specification. This version is the general-pur-
pose solution for high-level extensive and complex communication tasks.
Powerful services open up a wide range of applications and provide great flexibility.
PROFIBUS DP DP means Decentralized Periphery. PROFIBUS DP is optimized for high
speed and low-cost interfacing. It is specially designed for communication
between automation control systems and distributed I/O at the device level.
PROFIBUS PA PA means Process Automation. It permits sensors and actuators to be con-
nected to one common bus even in areas where intrinsically safe products are
required. It also permits data and power to be supplied over the bus using
2-wire technology according the international standard IEC 1158-2.
Uniform Bus Access
Protocol
!Caution It is not possible to exchange one of these family members by another family
PROFIBUS DP and PROFIBUS FMS use the same transmission technology
and uniform bus access protocol. Consequently, both versions can be operated simultaneously on the same bus. FMS field devices, however, cannot be
controlled by DP masters and vice versa.
member. This will cause faulty operation.
The rest of this section describes the PROFIBUS DP Protocol architecture.
1-1-2 PROFIBUS Communication Protocol
OSI reference model
ISO-7498
In general, the PROFIBUS communication protocol is based on the Open
System Interconnection (OSI) reference model in accordance with the international standard ISO-7498 (see the following illustration). The model defines
7 layers of communication functions, three of which - layers 1, 2, and 7 - are
used in PROFIBUS.
• Layer 1, the Physical Layer of this model, defines the physical transmission characteristics.
• Layer 2, the Data Link Layer of this model, defines the bus access protocol. This protocol also includes data security and the handling of transmission protocols and telegrams.
• Layer 7, the Application Layer of this model, defines the application functions. This Layer is only applicable to PROFIBUS FMS.

PROFIBUS DP In the rest of this manual, only PROFIBUS DP is considered.
Section 1-1
OSI Layer 1, 2 and User
Interface
PROFIBUS DP uses layers 1 and 2, and the user interface. Layers 3 to 7 are
not defined for PROFIBUS DP. The user interface Layer defines the interface
functions for specific application areas, i.e. the PROFIBUS DP basic functions
and communication profiles.This streamlined architecture ensures fast and
efficient data transmission. The application functions which are available to
the user, as well as the system and device behaviour of the various PROFIBUS DP device types, are specified in the user interface.
OSI Layer 1: Transmission
Medium
RS-485 transmission technology or fibre optics are available for transmission.
RS-485 transmission is the most frequently used transmission technology. Its
application area includes all areas in which high transmission speed and simple inexpensive installation are required. PROFIBUS modules are interconnected by single twisted-pair shielded copper wires.
RS-485 Technology The RS-485 transmission technology is very easy to handle. Installation of the
twisted pair cable does not require expert knowledge. The bus structure permits addition and removal of devices or step-by-step commissioning of the
system without influencing the other devices. Later expansions have no effect
on devices which are already in operation.
RS-485 Transmission
Speed
Transmission speeds between 9.6 kbit/s and 12 Mbit/s can be selected as
shown in the table below. One unique transmission speed must selected for
all devices on the bus when the system is commissioned.
Baud rate (kbit/s) Distance / segment (m)
9.6 1200
19.2 1200
45.45 1200
93.75 1200

500 400
1500 200
3000 100
6000 100
12000 100
Cable length The maximum cable length values depend on the transmission speed and are
based on type-A cable (see Cable Type on page 39). The length can be
increased by the use of repeaters.However, it is not recommended to use
more than three repeaters in series in a PROFIBUS network.

Overview of PROFIBUS
Section 1-1
1-1-3 Device Types
PROFIBUS distinguishes between master devices and slave devices.
Master Devices Master devices determine the data communication on the bus. A Master can
send messages without an external request, as long as it holds the bus
access right (the token). Masters are also referred to as active devices in the
PROFIBUS standard.
There are two types of master devices:
Class 1 Master (DPM1) A PROFIBUS DP Class 1 Master (DPM1) device is a central controller, which
exchanges information with the decentralized devices (i.e. DP slaves) within a
specified message cycle.
Class 2 Master (DPM2) PROFIBUS DP class 2 Master (DPM2) devices are programmers, configura-
tion devices or operator panels. They are used during commissioning, for configuration of the DP system, or for operation and monitoring purposes.
As of Unit Version 3.0 the CS1W-PRM21 and the CJ1W-PRM21 are PROFIBUS DP Class 1 as well as Class 2 Master devices.
Slave Devices Slave devices are peripheral devices. Typical slave devices include input/out-
put devices, valves, drives, and measuring transmitters. They do not have bus
access rights and they can only acknowledge received messages or send
messages to the master when requested to do so. Slave devices are also
called passive devices
Device Profile To enable the exchange of devices from different vendors, the user data has
to have the same format. The PROFIBUS DP protocol does not define the format of user data, it is only responsible for the transmission of this data. The
format of user data may be defined in so called profiles. Profiles can reduce
engineering costs since the meaning of application-related parameters is
specified precisely. Profiles have been defined for specific areas like drive
technology, encoders, and for sensors / actuators.
PROFIBUS DP-V1 PROFIBUS DP-V1 is an extension to the PROFIBUS DP protocol standard. It
defines acyclic message services between a PROFIBUS DP-V1 Master and a
PROFIBUS DP-V1 slave device. These acyclic message services allow
exchange of extended parameter settings as well as extended diagnostics
and alarm information, during regular I/O data exchange. PROFIBUS DP-V1
devices must at least support PROFIBUS DP.
PROFIBUS DP-V1 services are designated as MSACn services (M
S
lave Acyclic, Class n), in which n designates the Master Class (i.e. 1 or 2).
The CS1W-PRM21 and the CJ1W-PRM21 both support PROFIBUS DP-V1
Class 1 and Class 2 Master functions as of Unit version 3.0.

1-1-4 Bus Access Protocol
OSI Layer 2: Bus Access
Protocol
The PROFIBUS bus access protocol is implemented by OSI layer 2. This protocol also includes data security and the handling of the transmission protocols and messages.
Medium Access Control The Medium Access Control (MAC) specifies the procedures which determine
when a device is permitted to transmit data. A token passing procedure is
used to handle the bus access between master devices, and a polling procedure is used to handle the communication between a master device and its
assigned slave device(s).
4
Overview of PROFIBUS
Section 1-1
Token Passing The token passing procedure guarantees that the bus access right (the token)
is assigned to each master within a precisely defined time frame. The token
message, a special message for passing access rights from one master to the
next master, must be passed around the logical token ring - once to each
master - within a specified target rotation time. Each master executes this procedure automatically.
Polling Procedure The polling or master-slave procedure permits the master, currently in pos-
session of the token, to access its assigned slaves. The figure below shows a
possible configuration The configuration shows three active devices (masters)
and six passive devices (slaves).
Token Passing
DPM1 DPM2 DPM1
Active stations
Master devices
Passive stations
Slave devices
Polling
PROFIBUS
The three masters form a logical token ring. When an active device receives
the token message, it can perform its master role for a certain period of time.
During this time it can communicate with all assigned slave devices in a master-slave communication relationship, and a DPM2 master can take the initiative to communicate with DPM1 master devices in a master-master
communication relationship.
Multi-peer Communication In addition to logical peer-to-peer data transmission, PROFIBUS DP provides
multi-peer communication (broadcast and multicast).
Broadcast
Communication
In the case of broadcast communication a master device sends an unacknowledged message to all other devices (masters and slaves).
Multicast Communication In the case of multicast communication a master device sends an un-
acknowledged message to a predetermined group of slave devices.
1-1-5 Diagnostic functions
Extended Diagnostics Extended diagnostic functions defined in PROFIBUS DP enable the fast loca-
tion of error at slave devices. Diagnostic messages are transmitted over the
bus and collected at the master. Three diagnostic message types are defined:
Device Related
Diagnostics
• Messages concerning the general operational status of the whole device,
e.g. over temperature, low voltage.
Module Related
Diagnostics
Channel Related
Diagnostics
• Messages indicating that an error is present in a specific I/O range of a
device, e.g. an 8-bit output module.
• Messages indicating an error at a given input or output, e.g. short circuit
on Output 5.

Overview of PROFIBUS
Section 1-1
1-1-6 Protection Mechanisms
Monitoring Time PROFIBUS DP provides effective protection functions against parameteriza-
tion errors or failure of the transmission equipment. Time monitoring is provided both at the master and the slave devices. The monitoring interval is
specified when the system is configured.
Monitoring at the Master The PROFIBUS Master monitors data transmission of the slaves with the
Data-Control-Timer. A separate control timer is used for each slave. This timer
expires if response data is not correctly transmitted by the slave within the
monitoring interval. The user is informed when this happens. If the automatic
error reaction (Auto-CLEAR) has been enabled, the PROFIBUS Master exits
its OPERATE state, switches the outputs of all assigned slaves to the fail-safe
status and changes to the CLEAR state.
Monitoring at the Slave Slave devices use a watchdog to detect failures of the master or the bus. If
data communication with the master does not occur within the set watchdog
time interval, a slave automatically switches its outputs to the fail-safe mode.
Also, access protection is provided for the inputs and outputs of the slaves
operating in multi-master systems. Only authorized masters can access their
slaves.
1-1-7 Network Operation Modes
PROFIBUS DP distinguishes four different network operation modes:
OFFLINE • Communication with all PROFIBUS DP participants (masters and slaves)
is stopped. The Master ceases to access the PROFIBUS network.
STOP • Cyclic communication as well as PROFIBUS DP-V1 Class 1 communica-
tion between the master and its slaves is stopped. Only PROFIBUS DPV1 Class 2 communication and communication between the master and
other masters is still possible.
CLEAR • The master tries to set parameters, check the configuration, and perform
data exchange with its associated slaves. Data exchange involves reading
the inputs of the PROFIBUS DP slaves and writing zeros to the outputs of
the slaves.
OPERATE • The master exchanges data with its assigned slaves, inputs are read and
outputs are written. Also, the master cyclically sends its local status to all
its assigned PROFIBUS DP slaves (using a broadcast message).
The PROFIBUS Master Unit will always be in one of these four modes. Mode
transitions from one mode to another will be performed via intermediate
modes. For example, a mode transition from OFFLINE to OPERATE, will be
Auto-CLEAR
Fail-safe State
performed as OFFLINE
If an error occurs during the data exchange phase of the master, the ‘AutoCLEAR’ function determines the subsequent actions. If this function has been
disabled, the master remains in the OPERATE mode. If the function has been
enabled, the master automatically changes the network to the CLEAR mode,
in which the outputs of the assigned PROFIBUS DP slaves are switched to
zero, i.e. the ‘fail-safe’ state. The master continues to read the inputs of the
slaves.
→ STOP → CLEAR → OPERATE.

Setting up a PROFIBUS DP Network
Section 1-2
1-2 Setting up a PROFIBUS DP Network
1-2-1 Configuring the PROFIBUS Master
In order to operate a PROFIBUS network, each master in the network needs
to be configured. This process of configuration involves
• setting up the network topology, i.e. assigning the slave devices with
which the master will be exchanging data,
• defining the parameterization data, which the master will send to each of
the slave devices, before process data exchange can commence
• defining the configuration data, i.e. defining the process data, which will
be exchanged,
• setting up the bus parameters, which define the baud rate and the bus
timing parameters.
• downloading the configuration setup to the master device.
Configuration Technology The configuration process is usually facilitated by a special Computer based
program, often referred to as a configurator. The configurator requires special
configuration files, defining the configuration options for each device, which is
to participate in data exchange. The files must be provided by the manufacturer of the device.
Two types of configuration technology exist:
• Configuration technology based on FDT/DTM technology
• Configuration technology based on GSD-files
1-2-2 FDT/DTM Technology
FDT/DTM Technology The newer configuration tools are based on FDT/DTM technology.
FDT/DTM Concept The FDT/DTM concept specifies the interfaces between the engineering sys-
tems called Field Device Tools (FDT), and the device-specific software components called Device Type Managers (DTM).
The FDT/DTM concept separates the device dependent functionality (which is
in the DTM) from the application. It provides separate interfaces for device
configuration, monitoring and maintenance solutions, which before largely
depended on the manufacturer of the application. Because of this concept,
FDT/DTM technology is not limited to PROFIBUS applications. In concept,
any type of network can be configured and accessed, provided the appropriate DTMs are available.
FDT Container Application A FDT container application facilitates configuration of network devices and
parameterizing and/or manipulating their operational modes. All device
dependent functionality is concentrated in the DTM.
FDT container applications can be stand-alone tools, or can be part of other
engineering tools such web browsers providing FDT interfaces.Since FDT
standardizes the interfaces, it allows devices from different manufacturers to
be integrated in any automation system, regardless of the fieldbus system.
CX-Profibus is an example of a FDT container application. It is described in
detail in the following sections.
Device DTM DTMs are provided by the manufacturer of the device. A DTM is comparable
to a printer driver, which allows interactive configuration and diagnostics.
7
Setting up a PROFIBUS DP Network
The DTM provides not only the configuration, manipulation and monitoring
functions for a device including the user interface functions, it also provides
the connection technology to the device.
DTM Properties In general, a DTM is a Microsoft COM-component, which can be executed
from within a FDT container application. A DTM is not a stand-alone tool, it
requires a FDT container application to be executed. The DTM provides a
number of interface functions, through which it can be controlled and
accessed in order to transfer data to or from the DTM.
A DTM provides all the options for configuration and monitoring of a device,
which it can present to the user through its own user interface.
ActiveX User Interface The user interface for a DTM is provided using ActiveX windows. Control of
these windows is done by the DTM, but the FDT container application can
request specific user input from the DTM, based on which the DTM will provide the necessary ActiveX windows. In general multi-language user interface
windows, including DTM specific Help files are supported by the DTM.
XML based Data Transfer Data transfer to and from a DTM is provided using XML-documents. The
XML-documents are standardized for the communication between the FDT
container application and for communication between DTMs.
An additional specification covers the definition of XML-data formats for the
transfer of application specific data, such as PROFIBUS data.
Section 1-2
Communication DTM In general, a device configuration DTM is accompanied by a communication
DTM. This specific DTM facilitates device specific communication, e.g. for
downloading a configuration to a PROFIBUS Master Unit and/or for retrieving
monitoring information from PROFIBUS Master Unit. It may incorporate the
specific communication protocol, or rely on other available drivers.
CX-Profibus CX-Profibus is a FDT container application. Together with this container appli-
cation, OMRON provides five DTMs:
• A DTM to facilitate configuration and operation of the CS1/CJ1W-PRM21
PROFIBUS DP-V1 Master Units (As of Unit version 2.0).
• A DTM to facilitate configuration of the CS1/CJ1W-PRM21 PROFIBUS
DP Master Units (Unit version 1.0).
• A DTM to facilitate configuration of the C200HW-PRM21 PROFIBUS DP
Master Unit.
• A DTM to facilitate configuration of the SmartSlice GRT1-series
GRT1-PRT PROFIBUS Communication Unit.
• A DTM to facilitate integration of GSD file based devices into CX-Profibus (see section 1-2-3 GSD file Technology for more information).
1-2-3 GSD file Technology
GSD file Technology The older and most commonly used configuration technology is the based on
GSD files (General Slave Data file). A GSD file is a text file, containing the
characteristic features and configuration options of a device. The device data
base file of each device is loaded in the configurator and downloaded to the
master device.
GSD files are usually supplied with a Unit, or can be downloaded from the
Internet, either from the manufacturer's site, or from the GSD library of the
PROFIBUS International at http://www.profibus.com.
8
Setting up a PROFIBUS DP Network
GSD File Language The language used in the GSD file is indicated by the last letter of the file
extension, *.GS?:
Default = GSD
English = GSE
German = GSG
Italian = GSI
Portuguese = GSP
Spanish = GSS
The GSD files are prepared individually by the vendor for each type of device,
according to a fixed format. Some parameters are mandatory, some have a
default value and some are optional. The device data base file is divided into
three parts:
General Section • General specifications
This section contains the vendor name, the device name, hardware- and software release versions, device type and identification number, protocol specification and supported baud rates.
DP-master Section • DP master-related specifications
This section contains all parameters which only apply to DP master devices
(e.g. maximum memory size for the master parameter set, maximum number
of entries in the list of active devices, or the maximum number of slaves the
master can handle).
Section 1-2
DP-slave Section • DP slave-related specifications
This section contains all specification related to slaves (e.g. minimum time
between two slave poll cycles, specification of the inputs and outputs, and
consistency of the I/O data).
For PROFIBUS DP-V1 devices this section also specifies what services for
PROFIBUS DP-V1 are supported.
DTM versus GSD File When comparing the two configuration technologies, a GSD file only provides
information on the device characteristics and configuration options. It has no
GUI of its own, nor can it connect to the device itself. A GSD file always
requires a separate configurator program to interpret the data. In the FDT/
DTM concept all these device related functions are included in the DTM. The
DTM can be executed from any program, which provides FDT interfaces.
Sending PROFIBUS DP-V1 commands to a device from the configuration tool
is only possible using DTM technology. The GSD file does not provide this
means.
