!WARNING The CPU Unit refreshes I/O even when the program is stopped (i.e., even in

PROGRAM mode). Confirm safety thoroughly in advance before changing the
status of any part of memory allocated to I/O Units, Special I/O Units, or CPU
Bus Units. Any changes to the data allocated to any Unit may result in unex­pected operation of the loads connected to the Unit. Any of the following oper­ation may result in changes to memory status.

• Transferring I/O memory data to the CPU Unit from a Programming
Device.

• Changing present values in memory from a Programming Device.

• Force-setting/-resetting bits from a Programming Device.

• Transferring I/O memory files from a Memory Card or EM file memory to
the CPU Unit.

• Transferring I/O memory from a host computer or from another PC on a
network.

!WARNING Execute online edits only after confirming that no adverse effects will be

caused by extending the cycle time. Otherwise, the input signals may not be
readable.

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

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.

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.

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).

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.

1-3 PROFIBUS Master Unit

1-3-1 PROFIBUS Master Unit Features

PROFIBUS Master Unit The PROFIBUS Master Unit is a CPU Bus Unit, which can be installed on a

CS1/CJ1 PLC System. There are two available models of the PROFIBUS
Master Unit: the CS1W-PRM21 for connection to a CS1 PLC System and the
CJ1W-PRM21 for connection to a CJ1 PLC System. Both models provide
identical functionality.

CPU Bus Unit A total of up to 16 CPU Bus Units can be mounted on the CPU Rack or an

Expansion Rack. The total of 16 must include all PROFIBUS Master Units and
all other CPU Bus Units

Unit Control and Status Up to 25 words of control and status words are exchanged between the

PROFIBUS Master Unit and a dedicated CIO memory area, of which the loca­tion is related to the Unit Number. Control bits, allow the PLC program to
switch the Unit between OFFLINE, STOP, CLEAR and OPERATE mode,
which represent the main PROFIBUS DP modes of operation. The control
words also allow for user initiated transmission of a Global-Control message
over the PROFIBUS network to any group of slave devices.

The remaining CIO words provide status and diagnostics information on the
Unit itself, the PROFIBUS network and the slave devices.

I/O Data The total size of I/O data however, must not exceed the maximum I/O size of

up to 7168 words, which it can exchange with the PLC memory. The I/O data
can be distributed over up to two input areas and two output areas. Each of
the input and output areas can be mapped to any location in the DM Area,
CIO Area, WR Area, HR Area, or the EM banks.

FINS Messages The PROFIBUS Master Unit supports FINS message exchange with the PLC

CPU to allow the transfer of Slave diagnostics data, the Error log, or to enable
or disable communication with specific allocated slave devices, so that they
can temporarily be taken out of the network for maintenance, without the
PROFIBUS Master Unit reporting an error.

As of Unit version 2.0, FINS commands have been implemented to support
the transfer of data via acyclic PROFIBUS messages over the network. These
messages can be used to change a slave device address, read slave device
configuration, or to send and receive extended parameter data information.

As of Unit version 3.0, a FINS command containing CIP data can be sent to
other OMRON devices on the PROFIBUS network, using PROFIBUS DP-V1
Class 2 services. CIP or Common Industrial Protocol is protocol defined by
ODVA, the Open Devicenet Vendor Association. Refer to their website for
more information: http://www.odva.org/.

PROFIBUS DP Class 1
Services

The PROFIBUS Master Unit supports all mandatory Class 1 services defined
in the PROFIBUS DP standard EN50170, Volume 2 for Master - Slave Com­munication. These functions includes the following services:

• Set_Prm

• Chk_Cfg

• Slave_Diag

• Data_Exchange

• Global-Control (FREEZE, UNFREEZE, SYNC, UNSYNC, CLEAR)

The PROFIBUS Master Unit supports cyclic Master - Slave communications
for networks with up to 125 slave devices. With each slave device it can
exchange up to 244 bytes of input data and up to 244 bytes of output data.

10

PROFIBUS Master Unit

Section 1-3

For diagnostics purposes the PROFIBUS Master Unit collects all Slave Diag­nostics messages, which it can transfer to the PLC memory, using FINS com­mands. From every allocated slave device it can receive up to 244 bytes of
diagnostics data.

from the PLC CPU or from the associated DTM.

must be configured, using the dedicated configuration program CX-Profibus.
Without this configuration, the Unit will not be able to achieve data exchange,
neither to send any acyclic messages. The configurator is explained in section
1-4 CX-Profibus Configurator.

The PROFIBUS Master Unit is provided with a variety of troubleshooting func­tions for prompt recovery in case of errors:

• Extensive self-diagnostic function at startup

• Data exchange flags, indicating if I/O data is being exchanged with the
slave devices

• Diagnostics flags, indicating if new Slave diagnostics data is available

• Extensive status and error flags, indicating the status of the Unit and the
PROFIBUS network

CX-Profibus Configurator

Section 1-4

1-4 CX-Profibus Configurator

1-4-1 CX-Profibus Features

CX-Profibus The PROFIBUS Master Unit requires a configuration before it can exchange

I/O data with the slave devices. For this purpose OMRON provides the CX­Profibus Configuration program, which runs under Microsoft Windows™ NT

4.0, Windows™ 2000 or Windows™ XP

Together with CX-Profibus, OMRON provides five DTM COM Objects:

• A DTM to configure the CS1/CJ1W-PRM21 PROFIBUS DP-V1 Master

• A DTM to configure the CS1/CJ1W-PRM21 PROFIBUS DP Master

• A DTM to configure the C200HW-PRM21 PROFIBUS DP Master

• A DTM to configure the SmartSlice GRT1-series GRT1-PRT.

• A DTM to allow the handling of classic GSD files in CX-Profibus

The following provides a quick overview of the functions.

CX-Profibus FDT
Container Application

CS1/CJ1W-PRM21 DTM The two CS1/CJ1W-PRM21 DTMs provided to configure the CS1/CJ1W-

CX-Profibus provides an FDT environment in which DTMs can be executed.
The main function of CX-Profibus is to facilitate the DTMs and the data
exchange between them. It provides:

• Network setup functions: A tree view shows the relations between the
DTMs, i.e. the relation between the Master and slave devices.

• Device Catalogue functions: A Device Catalogue containing the installed
DTMs is maintained, to which the user can add new DTMs or delete
them. Device DTMs can be added to the network from this Catalogue.

• Project maintenance functions: CX-Profibus provides the functions to cre­ate, save and open project files. It facilitates user access control, which
limits of use to authorized personnel only, using password protection.

• Additional functions: CX-Profibus provides additional functions like print­ing, error logging, FDT Communication logging and help files.

PRM21 PROFIBUS DP Master Units and the CS1/CJ1W-PRM21 PROFIBUS
DP-V1 Master Units both provide the same basic PROFIBUS DP functions.
These DTMs consist of three parts:

• The Settings User Interface, which handles the configuration for the
PROFIBUS Master Unit. This includes the bus parameters settings, the
I/O data mappings and Master specific settings. The Settings DTM pro­vides its own user interface.

• The Monitoring User Interface, which handles the status monitoring and
control over the PROFIBUS Master Unit, when it is on-line and communi­cating over the PROFIBUS network. It provides its own user interface to
read out Master status flags and Error log, as well as Slave status flags
and the Slave diagnostics messages received by the Unit. It also allows
the user to send Global-Control messages over the network and to
change the PROFIBUS Master Unit’s mode on the PROFIBUS network.

• The communication interface between the CS1/CJ1W-PRM21 DTMs and
CX-Server. CX-Server, provided with the CX-Profibus package, is the
driver for communication between the PC and the PLC CPU.

CS1/CJ1W-PRM21
PROFIBUS DP-V1 DTM

C200HW-PRM21 DTM The C200HW-PRM21 DTM allows configuration of the C200HW-PRM21

In addition to the PROFIBUS DP functions, the CS1/CJ1W-PRM21 PROFI­BUS DP-V1 DTM provides:

• A communication channel to the user to change a remote slave device
address. This channel has its own user interface.

• Communication channels to facilitate data transfer through PROFIBUS
DP-V1 MSAC1 acyclic message transfer between a PROFIBUS DP-V1
slave device DTM and the physical slave device.

• Communication channels to facilitate data transfer through PROFIBUS
DP-V1 Class 2 acyclic message transfer between a PROFIBUS DP-V1
slave device DTM and the physical slave device. This also allows direct
connection to third-party PROFIBUS slave devices supporting PROFI­BUS DP-V1 Class 2, e.g. PROFIBUS PA devices.

PROFIBUS DP Master Unit. This predecessor of the CS1/CJ1W-PRM21 can
be used on existing C200H PLC CPU Systems as well as CS1 PLC Systems,
except for the CS1D.

The C200HW-PRM21 DTM consist of three parts:

• The Settings User Interface, which handles the settings for the C200HW­PRM21 PROFIBUS DP Master Unit, including the bus parameters set­tings, and the I/O data mappings.

• The Monitoring User Interface, to handle the Unit’s status monitoring. The
DTM’s user interface displays the Master status and Slave status.

• The communication interface between the two DTMs mentioned above
and the serial communication driver, to the C200HW-PRM21 PROFIBUS
DP Master Unit.

Note 1. This Operation Manual does not contain a detailed description of the

C200HW-PRM21 Unit, only a description of the DTM. For more details on
the C200HW-PRM21 refer to C200H-series PROFIBUS DP Master Units
Operation Manual (W349-E2-@).

2. The C200HW-PRM21 Unit and DTM do not support PROFIBUS DP-V1.

GRT1-PRT DTM

Generic Slave DTM The Generic Slave DTM allows the handling of classic GSD files of up to GSD

SmartSlice GRT1-series GRT1-PRT DTM allows configuration of the GRT1­PRT PROFIBUS Communication Unit and SmartSlice I/O Units. The DTM
provides the following user interfaces:

• The Configuration User interface to define the I/O configuration and
parameter setting for I/O data exchange with the PROFIBUS Master Unit.

• Configuration User Interfaces to configure individual SmartSlice I/O Units
attached to the GRT1-PRT.

• A monitoring User interface to monitor the status of the GRT1-PRT and
individual SmartSlice I/O Units.

revision 3 within CX-Profibus. Upon allocating a slave device, for which only a
GSD file is available to a Master Unit in the network, this DTM will be invoked.
This DTM consists of two parts:

• The Settings User Interface will provide the user interface to display the
device’s information and the selectable values, as defined in the GSD.
After making the necessary configuration settings, and saving them,
these will be transferred to the Master DTM.

• The Monitoring User Interface will provide a diagnostics interface to the
user, allowing him to check the Slave’s status. This DTM obtains the nec­essary information from the PROFIBUS Master Unit’s monitoring DTM.

Downloading the
Configuration

CS/CJ-series

ROFIBUS DP

Master Unit

After setting up the configuration, it must be downloaded to the PROFIBUS
Master Unit. The type of serial connection to use for downloading, depends
on the Unit:

• CS1/CJ1W-PRM21: Connection to the Unit is achieved through the serial
port of the PLC CPU, using CX-Server. CX-Server also allows routing the
download through multiple systems, if supported by these systems. The
CS1/CJ1W-PRM21 does not support message routing.

• C200HW-PRM21: Connection to the C200HW-PRM21 is achieved
through a serial RS-232c Connection between one of the PC’s Serial
COM Ports and the dedicated configuration connector at the front of the
Unit. For details, refer to the C200HW-PRM21 Manual: W349-E2-2. The

With CS/CJ-series PLCs, words are automatically allocated in the CIO Area
and the DM Area. The PROFIBUS Master Unit uses these words for receiving
control data from the CPU Unit and for notifying the CPU Unit of PROFIBUS
Master Unit and communications status. The word addresses in the allocated
areas for the CPU Bus Unit are important when creating the user program for
using the PROFIBUS Master Unit. This must be considered when setting the
unit number.

The CIO and DM Word allocations are discussed in detail in 4-2 Allocated

The signal RTS (TTL signal) is for the direction control of repeaters, which do
not have a self-controlling capability.

The signals DGND and VP are used to power the bus terminator located in
the cable connector.

Note The orientation of the sub-D connector allows the use of PROFIBUS connec-

tors with a 90° angle cable outlet, e.g ERNI, Delconec and Phoenix.

Note The 9-pin sub-D connector uses #4/40 UNC thread, for mechanical fixation of

the cable connector. Make sure that if non-standard PROFIBUS connectors
are used, the corresponding thread is used on the cable connector.

2-2-1 Handling Precautions

When installing the PROFIBUS Master Unit on the PLC system, observe the
following handling precautions

• Always turn OFF the power supply to the PLC before mounting or dis­mounting a Unit or connecting or disconnecting cables.

• Provide separate conduits or ducts for the I/O lines to prevent noise from
high-tension lines or power lines.

• Leave the label on top of the Unit attached when wiring. Removing the
label prior to wiring may result in malfunction if foreign matter enters the
Unit.

• Remove the label after the completion of wiring to ensure proper heat dis­sipation. Leaving the label attached may result in malfunction.

2-2-2 Mounting the CS1W-PRM21

The CS1W-PRM21 PROFIBUS Master Unit can be mounted to any slot in
either a CS-series CPU Rack, a CS-series Expansion CPU Rack or a CS1
Duplex CPU Rack. The CS-series PLC supports up to 7 Expansion CPU
Racks, in addition to the CPU rack.

The number of slots to which PROFIBUS Master Unit can be mounted
depends on the Backplane. Up to 16 PROFIBUS Master Units can be

Initial Setup Procedure

2-3-1 Selecting a unit number

1. Make sure that the PLC Power Supply is turned OFF before setting the
Unit number.

2. Set the switch to the desired unit number. Use a small screwdriver to make
the setting, taking care not to damage the rotary switch. The unit number
is factory-set to 0. Make sure that the unit number is unique on the PLC,
i.e. there must be no other CPU Bus Units with the same unit number.

3. Turn ON the PLC Power Supply.

After setting the unit number, the PLC CPU must now register the PROFIBUS
Master Unit, by creating an I/O table.

2-3-2 Creating an I/O table

An I/O table is used to identify Units connected to the PLC and to allocate I/O
to them. The I/O table is stored within the PLC CPU, and loaded at start up. If
any change is made to the Unit configuration of a CS/CJ-series PC, the I/O
table must be created again to register the Units to the CPU Unit.

Procedure for Creating an
I/O Table

To create the I/O table, connect a Programming Device (such as a Program­ming Console or CX-Programmer) to the PLC.

The following Programming Devices can be used with CS/CJ-series PLCs.

Programming Console

Model number Key Sheet (required) Recommended cable (required)

C200H-PRO27-E CS1W-KS001-E CS1W-CN224 (cable length: 2.0 m)

CS1W-CN624 (cable length: 6.0 m)

CX-Programmer and CX-Net

Model number: WS02-CXP@@-EV2

The operations are explained here using a Programming Console. For details
regarding the CX-Programmer and the CX-Net, refer to the CX-Programmer
User’s Manual.

CX-Net is software that comes with CX-Programmer and is automatically
installed when CX-Programmer is installed.

To connect a Programming Console, attach a CS/CJ-series Key Sheet and
then connect the Console to the CPU Unit’s peripheral port. (It cannot be con­nected to the RS-232C port.)

The procedure for creating an I/O table is shown here, taking as an example
an I/O table that is generated automatically for a PLC connected online. In this
example, a Programming Console is used for creating the I/O table. For an
explanation of how to create an I/O table using a CX-Programmer, refer to the
CX-Programmer User’s Manual.

Use the following procedure to create the I/O table.

After creating the I/O table, the Unit is ready to be configured for first use on
the PROFIBUS network.

Note After mounting the Unit and starting it up for the first time, the Unit’s Configu-

ration is empty. This will cause the red ERC LED on the front of the Unit to be
switched ON. In this situation, the Unit can still be configured.

2-4 Setting up a Network

2-4-1 Network Structure

Communication Medium The PROFIBUS standard defines the use of EIA RS-485 as the main commu-

nication transport medium. The PROFIBUS Master Unit is designed to inter­face directly to this type of medium. This section will discuss the setup of
networks based on this medium.

Note The other communication medium specified for PROFIBUS is optical fibre.

The PROFIBUS Master Units does not provide a direct interface to this type of
medium. However, by using third party couplers an interface between EIA RS­485 and optical fibre networks can be made.

Linear Bus Topology PROFIBUS DP defines the use of the Linear Bus Network Topology. The Bus

must be terminated at both ends, and must not contain network branches.
The total cable length of the bus depends on the cable and the selected baud
rate. Also, RS-485 specifies a maximum of up to 32 devices - master and
slave devices - per line segment. If more than 32 devices are to be con­nected, or if the total length of the segment must be extended beyond its max­imum, repeaters must be used to link the separate segments.

37

Setting up a Network

Section 2-4

Note Repeaters are devices which connect two segments. They do not have a

device address of their own, but they do count in the total number of devices
in a segment.

Repeaters A maximum of up to three repeaters between two devices in a network can be

used, i.e. a network can consist of up to 4 segments. The maximum number
of PROFIBUS devices in such a network is then 122. The figure below shows
an example of a two-segment network.

ments into a Tree topology. In a tree topology more than three repeaters are
allowed, provided that there are no more than three repeaters between any
two devices in the network. The following figure presents an example of a net­work with more than three segments and repeaters.

Section 2-4

Cable Type The PROFIBUS standard EN 50170 specifies Type A shielded, twisted- pair

cable as the recommended cable type for use in an RS-485 based PROFI­BUS network. This cable type has the following characteristics:

Characteristic Value

Impedance 135 - 165 ohms

Capacitance per unit length < 30 pF/m

Loop resistance 110 ohms/km

Core diameter 0.64 mm

Core cross section

0.34 mm

Note The PROFIBUS standard EN 50170 also specifies a Type B cable with differ-

ent cable characteristics. Use of Type B cable is no longer recommended.

Maximum PROFIBUS
Cable Length

The transmission speed defines the maximum advised cable distance or
cable segment in metres before the use of a repeater is recommended. The
cable lengths specified in the following table are based on PROFIBUS type A
cable.

Note 1. If network extension beyond the range of the advised cable length is re-

quired, the use of fibre optic cable to cross the larger distance should be
considered.

2. The recommended minimum cable length is 1 m.

Stub Lines Passive Stub lines (branches from the main line) should be avoided for data

transmission speeds of more than 500 kbit/s. Except at end devices with ter­mination, it is recommended to always use plug connectors that permit two
data cables to be connected directly to the plug. This method allows the bus
connector to be plugged and unplugged at all times without interrupting data
communication between other devices.

data lines, the data transfer cable must be terminated at both ends with a ter­minating resistor combination. The bus termination diagram is shown on the
left.

The bus terminator connects the two data lines via a 220 ohm resistor which,
in turn, is connected to VP 5Vdc and DGND via two 390 ohm resistors. Pow­ering the terminator resistor via VP 5V and DGND ensures a defined idle state
potential on the data lines.

To ensure the correct functioning up to the highest baud rate, the bus cable
must be terminated at both its ends.

A missing bus termination can cause errors during data transfer. Problems
can also arise if too many bus terminators are fitted, since each bus termina­tor represents an electrical load and reduces the signal levels and thus the
signal-to-noise ratio. Too many or missing bus terminators can also cause

39

Section 2-4

intermittent data transfer errors, particularly if the bus segment is operated
close to the specified limits for maximum numbers of devices, maximum bus
segment length and maximum data transfer rate.

Inductors In addition to the bus termination, additional precautions must be taken to

ensure proper operation at high baud rates, i.e. baud rates of 500 kbit/s and
higher. Due to the capacitive load of the device and the resulting cable reflec-

tions, bus connectors must be provided with built-in series inductors, of 110
mH each, as shown in the figure on the left.

Installing the inductors applies to all devices on the network, and not only to
the devices at both ends of the bus cable.

2-4-3 PROFIBUS Cable Connector

Bus Cable Connector The plug connector to be used on the CS/CJ-series PROFIBUS Master Unit is

a 9-pin male sub-D type, preferably encased in metal and having a facility to
connect the shield of the cable to the case or to pin 1. The cable should be
connected to the receive / transmit lines, pin 3 (B-line) and pin 8 (A-line).

The use of special PROFIBUS DP cable connectors, which are available from
several manufacturers, is highly recommended. Various models are widely
available, with or without the bus termination and inductors built-in. If provided
in the connector, the Bus termination can often be enabled or disabled
through a switch on the connector.

The special PROFIBUS DP cable connectors often provide a convenient way
of connecting the cables. The figure on the left, provides an example of such
a bus cable connector.

A standard 9-pin sub-D plug can only be used if the PROFIBUS Master Unit is
not at the start or the end of a bus segment, or on a stub line at a baud rate of
500 kbit/s or less.

To next
station

From

station

The two PROFIBUS data lines are designated A and B. There are no regula­tions on which cable core colour should be connected to which of the two data
terminals on each PROFIBUS device; the sole requirement is to ensure that
the same core colour is connected to the same terminal (A or B) for all
devices throughout the entire system (across all devices and bus segments).
The PROFIBUS Organization recommends the following rule for data line
colour codes: PROFIBUS cables in general will use the colours red and green
for the data lines, with the following assignment:

• Data cable wire A - green

• Data cable wire B - red

This rule applies to both the incoming and the outgoing data lines.

Defining PROFIBUS DP in the Software

Section 2-5

2-4-4 Shielding Precautions

Cable Shield Connection To ensure electro-magnetic compatibility (EMC), the shield of the cable

should be connected to the metal case of the plug connector.

Inside cabinet

Ground Rail

Outside cabinet

If the Unit is installed in a control cabinet, the bus cable shield should be
brought into physical contact with a grounding rail using a grounding clamp or
similar device. The cable shield should continue in the cabinet right up to the
PROFIBUS device.

Ensure that the PLC and the control cabinet in which it is mounted have the
same ground potential by providing a large-area metallic contact to ground,
e.g. galvanized steel to ensure a good electrical connection. Grounding rails
should not be attached to painted surfaces.

For further information regarding PROFIBUS network installation, please refer
to “Installation Guideline for PROFIBUS DP/FMS” (PNO Order No. 2.112),
which is available at every regional PROFIBUS Organization. The information
covers:

• Commissioning of PROFIBUS equipment.

• Testing the PROFIBUS cable and bus connectors.

• Determining loop resistance.

• Testing for correct bus termination.

• Determining the segment length and cable route.

• Other test methods.

• Example of an equipment report in the PROFIBUS guideline.

2-5 Defining PROFIBUS DP in the Software

Defining the Configuration After making the physical connections of the network, the configuration then

has to be defined in the software. OMRON provides a dedicated PC-based
configuration program, called CX-Profibus, as well as the required DTMs for
this purpose. It can be used to:

• Define the master(s).

• Assign slaves to their respective master(s).

• Define I/O Configuration and parameters of individual slave devices.

• Define bus parameters, e.g. baud rate, target rotation time etc.

Downloading the
Configuration

The system must be downloaded to the Master Unit after configuring it at the
PC. This is made possible by either connecting the serial COM port of the PC
to the CS1/CJ1 PLC with a serial interface cable, or use an ethernet connec­tion between the PC and the CS1/CJ1 PLC via an ethernet unit or Controller
Link unit.

Section 3-2

DTM List Window The list items in the right view are described in the following table.

DTM Group Selection
Window

Column

Device The Device column contains the names of the DTMs, as provided by

the DTM or the GSD file. If the device is defined by a GSD file, the
Generic Slave Device DTM reads out the GSD file entry “Model
Name”. The string provided by this variable is the name displayed in
the list.

Version The version number defines the revision number of the device. If the

device is defined by a GSD file, the Generic Slave Device DTM reads
out the GSD file entry “Revision”. The string provided by this variable is
the version number displayed in the list.

Date For DTMs, Date is the date associated with the revision. For GSD file

based slaves, the date listed in this column is the date the GSD file
was last modified.

Vendor The Vendor name is provided by the DTM or the GSD files.

Description

The left view allows selection of specific groups of device DTMs with common
attributes, e.g. Vendor name, Protocol type etc. If a group is selected, all

the same time.

59

CX-Profibus

3-2-5 Adding Devices to the Network

Setting up a network in CX-Profibus involves adding and configuring single
device DTMs. The device DTMs as listed in the Device Catalogue can be
added to the network in three ways:

• Using the context menu
A context menu will pop up when selecting the CS1/CJ1W-PRM21
PROFIBUS Master DTM and right clicking the mouse. By selecting the
menu option Add Device, a simplified Device Catalogue is displayed,
allowing only a selection of DTMs which can be added to the PROFIBUS
Master DTM.

• Using the Drag & Drop function
A Device DTM listed in the standard Device Catalogue window can be
dragged and dropped from the Device Catalogue to a desired position in
the Network view.

• Using the Add Device button
A device DTM selected in the Device Catalogue can be added to a
selected Master DTM in the Network view by clicking the Add Device but­ton in the Device Catalogue window.

Section 3-2

3-2-6 Saving and Opening Projects

A project, containing various DTMs can be saved and opened to and from
hard disk. Saving a project file is accomplished by selecting the File - Save or
File - Save As... menu option. This will display the standard Windows File
selection window, allowing the user to enter a file name.

The Project File is saved with the extension *.CPR.

Saving the data is initiated from CX-Profibus, but every DTM must support the
save function as well. The settings of each DTM are added to the Project file
by the DTM itself.

A Project file can be opened using the File - Open menu option. This will
open the standard Windows File selection window, after which the Project file
can be selected and opened.

Note When opening a Project file, the network tree view is constructed. However,

for performance reasons, the DTMs are not directly instantiated. The advan­tage is that the tree view is constructed fast, but opening a DTM from the tree
view may take longer, depending on the performance of the PC used.

A Project File can also be opened from Windows Explorer. Double-clicking a
file with extension *.CPR will invoke CX-Profibus and open the selected file.

3-2-7 Exporting to HTML

CX-Profibus provides automatic generation of project documentation upon
command of the user. The documentation is generated in HTML format, and
can cover either single DTMs or the whole project. After generation of the
HTML document, it will automatically launch the default Internet browser, to
display the result.

Exporting Project to HTML Exporting the project information to HTML can be achieved in two ways.

• Select the main menu File - Export Project as HTML option.
A window will pop up displaying the progress of the export process.

mouse to display the context menu. A window will pop up displaying the
progress of the export process.

After exporting the information, the default browser is launched, showing the
result of the export process. Links are available to open the information pages
for the individual DTMs.

The extent of the information made available depends on the individual
DTMs. This can range from device type and version information up to all set­tings and selections made for the device.

Exporting DTM
Information to HTML

1,2,3... 1. Select the DTM in the Network view.

Exporting single DTM information to HTML is achieved by the following
sequence.

2. Right click the mouse to bring up the context menu.

3. Select the Export to HTML option from the context menu.

A window will pop up displaying the progress of the export process. When fin­ished, CX-Profibus will launch the default browser to display the result. In this
case however, no links will be available to other DTMs in the network.

3-2-8 Error Logging and FDT Monitoring

CX-Profibus provides two logging windows at the bottom of the application
window. Both windows are used for displaying events.

Error Log view The Error Log view displays error messages reported by the DTMs and by the

CX-Profibus FDT container application. All messages include the Time and
Date of occurrence, as well as the DTM Name, as shown in the Network view.

Purpose of the Error Log The purpose of the Error Log view is error reporting as well as troubleshoot-

ing. The contents of the window can be copied to the clipboard, to allow it to
be pasted into another document or into an E-mail. The errors themselves as
well as the sequence of errors may hold additional clues in case of problems.

Error Log Format The format used in the Error Log view is

Time: <Time> Date: <Date> - <DTM name> <message>

The message displayed, originates from the DTM in which the error occurred.

The figure below shows an example of an error message sequence. This
example sequence is generated after attempting to change a slave address to
that of another slave already assigned to the same Master Unit.

By right-clicking the mouse cursor in the Error Log view, a context menu is
displayed. This context menu provides the options listed below.

Section 3-3

Device Setup Tab The Device setup tab (see figure above) provides the controls to achieve

communication between the PC and the PROFIBUS Master Unit. It allows
setting of the unit number to identify it on the PLC system and the device
address to identify it on the PROFIBUS network. It also will invoke the CX­Server interface to setup and test the communication between the PC and the
PLC to which the Unit is attached.

The Device Setup tab has the following components.

Settings Box The Settings box contains the setting the user must make before setting up

the communication and before testing the communication.

Control Description

Station Address Address of the Unit in the PROFIBUS network. Default value is

1, but it should be changed if there is already another device
with that number.

Unit Number This number must be the same as the number selected with the

Configure Button The Configure button invokes the CX-Server communications settings dia-

log. CX-Server is the driver software, providing the communication functional­ity between a PC and the PLC CPU. It is the basis for the OMRON’s CX-One
programs.

CX-Server is provided with CX-Profibus, but it may already be installed on the
PC, if other programs, for example CX-Programmer have been installed.

Unit Number Selector switch on the front of the Unit (refer to
2-3-1 Selecting a unit number). This number is used in the com­munication between the PC and the PLC to transmit the mes­sages to the targeted PROFIBUS Master Unit

Note The CX-Server is designed to manage the communication between the PC

and the PLC and also configure the connected PLC. CX-Server currently sup­ports CS1G-H, CS1H, CS1H-H, CJ1G-H, CJ1H-H CJ1M and CS1G/CJ1G
PLC types.

Section 3-3-3 Connecting to the CS1/CJ1W-PRM21 will provide more details
on how to configure CX-Server.

Test Button The purpose of the Te st button is to test the communication setup, after CX-

Server has been configured. If the PC and the PLC are connected, selecting
the Test button, will invoke a FINS request message to the PROFIBUS Mas­ter Unit via the PLC, to read its name and firmware version. If the request suc­ceeds, both will be displayed in the Device Information Box.

If the FINS request fails (no response), an error message will be displayed in
the Error Log view. In this case the Firmware version field will revert back to
its default contents, i.e. “--- “.

GRAM modem (e.g. stay in OPERATE mode).

Go to CLEAR Mode
(default setting)

The Unit goes to the CLEAR mode whenever the PLC
goes to the PROGRAM mode.

Auto-CLEAR Box Auto-CLEAR defines the Unit’s behaviour in case an error occurs in one of the

allocated slave devices, which causes it to stop data exchange with the Mas­ter Unit. If Auto-CLEAR is enabled, the Unit will automatically transition to the
CLEAR state and force all its allocated slave devices to the ‘safe’ state, i.e. all
outputs are set to 0, using the Global-Control CLEAR command.

Control Description

Auto-CLEAR Mode ON Selected Unit transitions to the CLEAR mode in the event

of a network error, e.g. because one or more configured
slaves are not in the Data Exchange mode.

Auto-CLEAR Mode OFF

(default setting)

Selected Unit does not transition to CLEAR mode, but
attempts to re-parameterize the slave device.

Support Box The Auto Addressing in the Support Box defines the I/O Mapping process

when adding/removing I/O modules or when editing an existing I/O Mapping.
Refer to section 6-5-2 Mapping I/O Data for more details on I/O mapping.

New I/O modules are appended to the existing mapping.
Changed I/O modules will be re-allocated to the end of the

Bus Parameters Tab The Bus Parameters tab contains the parameters for the communication on

the PROFIBUS network. The Bus Parameters tab is shown below.

The Bus Parameters are a number of settings which define the communica­tion behaviour and timing on the PROFIBUS network. The Bus Parameters
depend on the selected baud rate, certain slave communication parameters
as well as the number of I/O data bytes exchanged between the Master Unit
and each of the slave devices.

The required combination of Bus Parameters is calculated by the program,
based on the dependencies mentioned above. However, the user can change
selected Bus Parameter manually if the application requires this.

Section 3-3

!Caution Changing the calculated Bus Parameters manually is not recommended, and

should only be performed if this is really necessary. Changing the Bus Param­eters to an invalid combination, may result in Unit malfunctioning and unex­pected behaviour.

Note When making changes to Bus Parameters, selecting the Optimize buttons,

allows toggling between the optimized values and the changed values.
Selecting another baud rate after changing parameters, will reset the Bus
Parameters to default values for the new baud rate.

The table below lists the parameters, shown in the Bus Parameter tab.

Slave Area Tab The Slave Area tab displays the mapping of the I/O data from/to the allocated

slave devices on to the PLC memory areas. The mapping can be made auto­matically, but can also be changed by the user, before downloading.

The Slave Area tab is shown below. Only the Output Allocation tab is shown.

Allocation Areas The Slave Area allocation tabs define how the I/O data of each of the slave

devices is mapped on to the PLC memory. The Slave area tab contains two
tabs, one for Output Allocation and one for Input Allocation. Each tab contains
an overall module list, showing all the output or input data per slave, along
with the Module names, sizes, data types and start addresses. This data has
been transferred to the Master DTM by each of the allocated slave DTMs. If
no slave devices have been allocated, or configured, the list will be empty.

Module List Box The Module List Box list contains the following information (refer to figure

above, the table applies to the lists in the Input and Output Allocation tabs).

Column Description

#Addr. Station address on the network, obtained from the slave DTM.

Index Index number of the I/O module.

Device Device name, obtained from DTM.

Module System generated name.

Size Module data size, unit of type mentioned in next column.

Type Module data type, e.g. Byte, Word etc.

Addr Mapped address area in PLC memory. For example: CIO3200,

equals CIO Area, start address 3200.

I/O Mapping Areas Each Output/Input Allocation tab also contains two areas on to which the I/O

data can be mapped. The areas will in turn be mapped to the PLC memory.
By default all data is mapped to Area 1, in order of ascending slave device
address.

72

Note 1. When mapping, the modules are copied from the module list to the map-

ping Area and not moved. This means that the module list acts as a re­source for the two Mapping Areas, below the module list.

CS1/CJ1W-PRM21 PROFIBUS Master DTM

Section 3-3

2. When adding/removing slaves/modules, and Auto Addressing has been
enabled, the modules in the Areas will be remapped. This usually results in
I/O data being re-mapped. Therefore it is recommended to select all slaves
and modules, before setting up the PLC memory mapping configuration.

!Caution The default mapping of areas on to the PLC memory is the same default map-

ping as used in the CS1/CJ1W-DRM21 Devicenet Master/Slave Unit. Care
should be taken to avoid data overlap, if such a Unit is part of the same PLC
CPU system as the CS1/CJ1W-PRM21 PROFIBUS Master Unit.

Mapping Area Controls Each mapping Area in the Allocation tab is equipped with four controls and an

information field located below the Area. The controls and information field
are listed and explained in the table below.

2. If an invalid setting is made the Occupied length value will change its co­lour to red, indicating an invalid setting. In addition, a warning message will
be displayed, upon saving the changes. Invalid settings are for example

• The start address and length definitions of the data block will cause it
to exceed the area in the PLC.

• The data mapping of two or more I/O Areas (Output and/or Input) will
be overlapping each other partly or totally in the PLC memory.

3. The Compress button will be disabled, i.e. grayed out, when Auto-Ad­dressing (see Master Setup Tab on page 68) has been enabled.

the slave device. If a response is not received with the specified timeout inter­val, the connection will be aborted by the Master unit.

The value can be set in the range of 1 to 32767, and is expressed in units of
10 ms.

Additional functions Two additional functions are provided to the user, via the DTM context menu:

• Slave DTM Address Assignment.

• Set Device Station Address (only available on DTM version 0.2.0.0 or
higher and for CS1/CJ1W-PRM21 Unit versions 2.0 or higher).

To select these options perform the following steps:

1,2,3... 1. Select the Master DTM in the Network view.

2. Right click the mouse, and select the Additional functions entry from the
context menu.

3. Select the desired function.

CS1/CJ1W-PRM21 PROFIBUS Master DTM

Section 3-3

Slave DTM Address
Assignment

Selecting the Slave DTM Address Assignment displays a list of DTMs
assigned to the PROFIBUS Master DTM, together with their Station address:

When assembling the network, the PROFIBUS Master DTM will automatically
assign a station address to each new slave DTM. The purpose of the Slave
DTM Address Assignment function is to allow the user to change the DTM
address of one or more devices, to make it the same as the actual physical
address of the device on the network.

In order to change an address perform the following steps:

1,2,3... 1. Select the slave device in the list.

2. Enter the new address in the field Address in the lower right corner of the
window.

3. Press the Set button. The Status field will display the status of this service,
i.e. whether or not the slave device responded without error.

Set Device Station
Address

The Set Device Station Address function is provided for slave devices of
which the PROFIBUS address is not set through switches, but by using the
PROFIBUS DP Set Slave Address service. Slave devices which support this
service also provide a means to store the address in internal non-volatile
memory. In case this non-volatile memory does not contain an entry, the
slave device will assume the default address 126.

Note 1. The PROFIBUS DP Set Slave Address service is supported by the CS1/

CJ1W-PRM21 Units as of Unit version 2.0.

2. In order to be able to change a device’s address, the CS1/CJ1W-PRM21
PROFIBUS Master DTM must be on-line.

Selecting the Set Device Station Address displays the window shown below:

77

CS1/CJ1W-PRM21 PROFIBUS Master DTM

In order to change the address of a slave device perform the following steps
(Make sure that the DTM is on-line with the CS1/CJ1W-PRM21 Unit):

1,2,3... 1. Enter the device’s current address and its PROFIBUS Ident Number.

The PROFIBUS Ident Number can be found in the Generic Slave DTM or
through the device’s documentation. By default the device’s current ad­dress will be 126. If necessary, change this to the actual current address.

2. Enter the new device address in the New Address field.

3. Optionally, select the Lock checkbox, if the address change must be made
permanent.

4. Press the Set button to invoke the PROFIBUS DP Set Slave Address ser­vice. The Status field will display the status of this service, i.e. whether or
not the slave device responded without error.

!WARNING Selecting the Lock option makes any future changes of the address impossi-

ble, even after power-down/power-up of the slave device.

Note After successful completion of the address change, the device DTM address

in the Network view has to be changed as well.

Section 3-3

3-3-2 Diagnostics User Interface

Diagnostics User Interface The PROFIBUS Master DTM provides a second user interface, to display the

Diagnostics information available in the PROFIBUS Master Unit. This infor­mation concerns

• Unit and PROFIBUS DP Interface status flags.

• Slave status flags and common slave diagnostics.

• The Unit’s Error Log.

Furthermore, the Diagnostics User Interface allows changing the Master’s
PROFIBUS operational mode and the transmission of Global-Control mes­sages.

In order to access the Diagnostics User Interface, the DTM has to be on-line,
i.e. a communication channel between the DTM and the PROFIBUS Master
Unit must have been established.

Opening the DTM
Diagnostics User Interface

1,2,3... 1. To go on line, perform one of the following actions.

In order to open the DTM Diagnostics User Interface perform the following
sequence.

• Select the DTM in the Network view.

• Select the Device - Go Online option from the main menu, or from the
DTM context menu, or

• Select the button from the Tool Bar.

78

2. A communication channel will be opened through CX-Server. The name of
the DTM in the Network view, will turn to Italic font, to indicate that the Unit
is on-line.

3. Select the Device - Diagnosis option from the main menu, or from the
DTM context menu. The Diagnostics User Interface will now be displayed.

CS1/CJ1W-PRM21 PROFIBUS Master DTM

The figure below shows an example of the DTM Diagnostics User Interface.

Section 3-3

The DTM Diagnostics User Interface contains two tabs:

• The Monitor tab
This tab displays all Master Unit status and error information as well the
overall slave status information, which resides in the Master Unit.

• The Online Operations tab
This tab contains controls to initiate state changes in the Master Unit as
well as transmit Global-Control messages over the PROFIBUS network.

Monitor Tab The DTM Diagnostics User Interface - Monitor tab contains three sub-tabs:

• Master Status tab.

• Slave Status tab.

• Error History tab.

Also, the Diagnostics data refreshing mode can be selected.

• Automatic
The Diagnostics data is constantly retrieved from the Unit.

• Manual
The Diagnostics data is retrieved only once from the Unit, when pressing
the Manual button.

Master Status Tab The Master Status tab (shown in the figure above) contains Diagnostics infor-

mation regarding the Master Status. Each of the four status boxes, is related
to one of the Unit’s status words in the PLC CIO Area Memory (see sections
4-2-3 Unit Status (Word n+4) to 4-2-6 Slave Status (Word n+7)).

The status is indicated by red or green LED indicators. Red indicates an error
situation, green indicates a status indication. The LED indicators are listed in
the table below.
