6 Conformance to EC Directives

6-1 Applicable Directives

•EMC Directives

• Low voltage directive EN 61131-2:1994+A12:2000

6-2 Concepts

EMC Directives OMRON Units complying with EC Directives also conform to related EMC standards making them eas ie r t o i ncorporate in other Un its or machines. The 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 confir m th at units a nd th e overall system conforms to EMC standards.

Note Applicable EMS (Electromagnetic Susceptibility) and EMI (Electromagnetic

Interference standards in the EMC (Electromagnetic Compatibility) standards are as follows:

Unit EMS EMI

CS1W-PRM21 EN 61000-6-2:2001 EN 61000-6-2:2001 CJ1W-PRM21

6-3 Conformance to EC Directives

PROFIBUS-DP Units that meet EC directives must be installed as follows:

Conformance to EC Directives

Units that meet EC directives also meet the common emission standard (EN50081-2). The measures necessary to ensure that the standard is met will vary with the overall configuration. You must therefore confirm that EC directives are met for the overall configuration, par ticularly any radiated emission requirement (10 m).

1-1 Overview of PROFIBUS

1-1-1 Introduction

Standard EN50170r 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 wh ich PROFIBUS adheres, guarantees vendor independence and transparen cy 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 a nd 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 s am e 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 (O SI) reference model in accordance with the international standard ISO-7498 (see the following illustration). It defines c ommunication layers 1, 2, and 7.

• Layer 1, the Physical Layer o f this model, defines the physical transmission characteristics.

• Layer 2, the Data Link Layer of this model, defines the bus access protocol. This protocol also includ es data security and the handling of transmission protocols and telegrams.

Overview of PROFIBUS

Section 1-1

• Layer 7, the Application Layer of this model, defines the application functions. This Layer is only applic able to PROFIBUS-FMS.

DP-Extensions User Interface Layer DP Basic Functions (7) Applicati on Layer (6) Presentation Layer (5) Session Layer NOT DEFINED (4) Transport Layer (3) Network La yer (2) Data Link Layer Fiel dbus Data Link (FDL) (1) Physi cal Layer RS485 / Fibre Optics

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 appl ication functions whi ch 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: T ransmission 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 h igh transmiss ion spee d and s imple inexpensive installation are required. PROFIBUS modules are interconnected by single twisted-pair shielded copper wires.

RS-485 tech n olo g y 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 stations or step-by-step commissioning of the system without influencing the other stations. Later expansions have no effect on stations 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 sel ected for all devices on the bus (master and slave devices) when the system is commissioned

Baud rate (kbit/s) Distance / segment (m)

9.6 1200

19.2 1200

45.45 1200

93.75 1200

187.5 1000 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

). 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 stations 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 stations (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 pur poses.

The CS1W-PRM21 and the CJ1W-PRM21 are bot h PROFIBUS-DP Class 1 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. Slaves are also called passive stations

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 def ined in so called pro files. 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.

1-1-4 Bus Access Protocol

OSI Layer 2: Bus access protocol

Medium Access Control The Medium Access Control (MAC) specifies the procedures which determine

Token passing The token passing procedure guarantees that the bus access right (the token)

The PROFIBUS bus access protocol is implemented by OSI layer 2. This protocol also includes data security and the ha ndling of the transmission protocols and messages.

when a station 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 h andle the communication b etween a master device and its assigned slave device(s).

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. A user can only change the target rotation time, but is not recommended.

Polling procedure The po lling or m aster-slave proce dure perm its the m aster, currently in pos-

session of the token, to access its assigned slaves. The figure below shows a possible configuration The configuration shows three active stations (masters) and six passive stations (slaves).

The three masters form a logical token ring. When an active station 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 stations in a master-slave communication relationship, and a DPM 2 master can take th e i nitiative to communicate with DPM1 master stations 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 station sends an unac-

knowledged message to all other stations (masters and slaves).

Multicast communication In the case of multicast comm unication a master station s ends an unacknow-

ledged message to a predetermined group of stations (masters and slaves).

1-1-5 Diagnostic functions

Extensive Diagnostics Extensive 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 levels of diagnostic messages are defined:

Device Related Diagnostics

Module Related Diagnostics

Channel Related Diagnostics

• Messag es conc erning the general operat ional s tatus of the whole device, e.g. over temperature, low voltage.

• Messages indicating that an error is present in a specific I/O range of a station, 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-DP 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 inter val. The user is informed when this happens. If the automatic error reaction (Auto-CLEAR) has been enabled, the PROFIBUS-DP 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 wi thin 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 States

PROFIBUS-DP distinguishes four different network states:

OFF-LINE • Communi cation with al l PROFIBUS-DP participants (masters and slaves)

is stopped. The Master ceases to access the PROFIBUS network.

STOP • Communica tion bet ween the master and its slaves is stopped. O nly com -

munication between the master and other masters is still possible.

CLEAR • The ma ster tries to s et 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 as signe d s laves, inputs are read a nd

outputs are written. Also, the master cyclically sends its local status to all its assigned PROFIBUS-DP slaves (using a broadcast message).

Auto-CLEAR

Fail-safe State

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 state. If the function has been enabled, the master automat ically changes the network to the CLEAR state, in which the outputs of the assigned P ROFIBUS-DP slaves are switched to zero, i.e. the ‘fail-safe’ state. The master continues to read the inputs of the slaves.

Setting up a PROFIBUS-DP Network

Section 1-2

1-2 Setting up a PROFIBUS-DP Network

1-2- 1 Configuring the PROFIBUS-DP Master

In order to operate a PROFIBUS network, each m aster in the ne twork needs to be configured. This process of PROFIBUS master configuration involves

• setting up the network topology, i.e. assigning the slave stations with which the master will be exchanging data,

• def ining the para meter iz atio n dat a, w hich t he m ast er w ill se nd to each of the slave devices, before process data exchange can commence

• defining the c onfiguration 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 Com puter 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 enginee ring 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 opens up interfaces for device configuration, monitoring and maintenanc e solutions, which before were largely manufacturer-specific interfaces. 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 appl ication. It is described in detail in the following sections.

Device DTM DTMs are provided by the manufac turer of the device. A DTM is comparable

to a printer driver, which allows interactive configuration and diagnostics. 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.

Setting up a PROFIBUS-DP Network

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 tr ansfer 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 containe r application can request specific user input f rom the DT M, 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 X ML-data formats for the transfer of application specific data, such as PROFIBUS data.

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-DP Master Unit and/or for retrieving monitoring information from PROFIBUS-DP Master Unit. It may incorporate the specific communication protocol, or rely on other available drivers.

Section 1-2

CX-Profibus CX-Profibus is a FDT container application. Together with this container appli-

cation, OMRON provides two DTMs:

• A DTM to facilitate configuration of the CS1W-PRM21/CJ1W-PRM21 PROFIBUS Master Units

• A DTM to facilitate integration of GSD file based devices in to CX-Profibus (see section

1-2-3 GSD file Technology

for more information)

1-2-3 GSD file Technology

GSD file technol ogy The older and most com mon ly us ed co nfiguration tech nology is the bas ed on

GSD files (Gerätestammdaten 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 configurato r and downloaded to the master device.

GSD files are usually sup plied with e ach unit. Alter natively, GSD files can be downloaded from the Inter net , either f rom the manufacturer's site, or from the GSD library of the PROFIBUS Nutzer Organisation at http://www.profibus.com.

GSD file language The language used in the GS D file is indicated by the last letter of the file

extension, *.GS?: Default = GSD

English = GSE German = GSG Itali a n = GSI Portuguese = GSP Spanish = GSS

PROFIBUS-DP Master Unit

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 divide d into three parts:

General section • General specifications

This section contains the vendor name, the device name, hardware- and software release versions, station type and identification number, protocol specification and supported baud rates.

DP-master section • DP master-related specifications

This section contains all parameters which onl y apply to DP master devices (e.g. maximum memory size for the master parameter set, maximum number of entries in the li st of active stations, 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).

DTM versus GSD file When comparing the two configuration technologies, a GSD file only provides

information on the device characteristics and conf iguration options. It has no GUI of its own, nor can it connect to the device itself. A GSD file always requires a separate configu rator program to interpret t he 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.

Section 1-3

1-3 PROFIBUS-DP Master Unit

1-3-1 PROFIBUS-DP Master Unit Features

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

a CS1/CJ1 PLC System. Th ere are two available models of the PROFIBUSDP Master unit: the CS1W-PRM21 for connection to a CS1 PLC System and the CJ1W-PRM21 for connection to a CJ1 PLC System . Both mode ls provide identical functionality.

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

Expansion Rack. The total of 16 must include all PROFIBUS-DP 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-DP Master Unit and a dedicated CI O memor y area, of whi ch the location is related to the Unit Number. Control bits, allow the PLC program to switch the Unit between OFF-LINE, 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_Con trol messa ge over the PROFIBUS network to any group of Slave stations.

The remaining CIO words provide status and di agnostics information on the Unit itself, the PROFIBUS network and the Slave stations allocated to the PROFIBUS-DP Master unit.

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

up to 7168 words, whic h i t ca n exchange wi th th e PLC memor y. The I/O data

PROFIBUS-DP Master Unit

can be distributed over up to two input areas and 2 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-DP Master Uni t suppor ts FINS message exchange with the

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

PROFIBUS-DP functions The PROFIBUS-DP Master Unit suppor ts all mandatory ser vices 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_Contr o l (FREEZE, UNFREEZE, SYNC, UNSYNC , C LE AR)

The PROFIBUS-DP Master Unit suppor ts cyclic Master - Slave communications for networks with up to 125 Slave stations. With each Slave station it can exchange up to 244 bytes of input data and up to 244 bytes of output data.

For diagnostics purposes t he PROFIBUS-DP Master Unit collects all Slave Diagnostics messages, which i t ca n be transferred to the P LC memory, using FINS commands. From every allocated Slave station it can receive up to 244 bytes of diagnostics data.

Section 1-3

Configuration Before t he P ROFIBUS-DP Ma ster Unit can control the PROFIBUS networ k, it

must be configured, using the dedicated configuration program CX-Profibus. Without this configuration, the Unit will not be able to achieve data exc hange.

Troubleshooting Functions

The Configurator is explained in section The PROFIBUS-DP Master Unit is provided with a variety of troubleshooting

functions for prompt recovery in case of errors:

• Extensive self-diagnostic function at start up

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

• Diagnos tics flags, indicating if new Slave diagnostics data is available

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

• Error log for recording error history data

1-4 CX-Profibus Configurator

1-4-1 CX-Profibus Fe atu r es

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

exchange I/O data with the Slave stations. For this purpose OMRON provides the CX-Profibus Configuration program, which runs under Microsoft Windows™ NT 4.0, Windows™ 2000 or Windows™ XP

Together with the CX-Profibus Container applicat ion, OMRON provides two DTM COM Objects:

• A DTM to configure the CS1W-PRM21 / CJ1W-PRM21

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

The following presents a quick overview of the functions.

CX-Profibus FDT Container application

CS1W-PRM21/CJ1-PRM21 DTM

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 con taining 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 func tions: CX-Profibus provides the functions to create, save and open project files. It also facilitates user access control, allowing the limitation of use to authorized personnel only, using password protection.

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

The CS1W-PRM21/CJ1W-PRM21 DTM consists of three parts:

• The Setting s DTM, which handles the configuration for the PROFIBUSDP 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 DTM, which handles the status monitoring and control over the PROFIBUS-DP 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-DP Master Unit’s mode on the PROFIBUS network.

• The com munication DTM, which provides the interface between the t wo DTMs mentioned above and CX-Server. Cox-Server, which is provided with the CX-Profibus packages is the driver providing communication between the PC and the PLC CPU.

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

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

• The Settings D TM will provide the user interface to display the device’s information and the selectable values, as defined in the GSD. After making the neces sary confi guration settin gs, these will be trans ferred to t he Master DTM automatically.

CX-Profibus Configurator

Section 1-4

• The monitoring DTM 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-DP Master Unit’s monitoring DTM.

Downloading th e configuration

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

• CS1W-PRM21/CJ1W-PRM21: Connection to the Unit is achieved through the serial port of the PLC CPU, using CX-Server. Cox-Server also allows routing the download through multiple systems, if supported by these systems. The CS1W-PRM21/CJ1W-PRM21 Units do not support message routing.

The signals DGND and V P are used to power the bus ter minator 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-DP Master Unit on the PLC system, observe the following handling precautions

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

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

• Leave the label on top o f the Unit attached when wirin g. 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.

Initial Setup Procedure

2-3-1 Selecting a unit number

1. Make sure that the PLC Po wer 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 dama ge the rotary switch. Th e un it number is factory-set to 0. Make sure that the unit num ber is uni que 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 CP U must now register the PROFIBUS-DP Master Unit, by creating an I/O table.

2-3-2 Creating an I/O ta ble

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 with the PLC CPU, and loaded at start up. If any change is made to the Unit c onfiguration of a CS/CJ-series PC, the I/O table must be created again to register the Units to the CPU Unit.

After creating the I/O table, the Unit is ready to be configured for first use on the PROFIBUS-DP 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-DP Master Unit is designed to interface directly to this type of medium. T his s ection wi ll discuss the s etup of networks based on this medium.

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

The PROFIBUS-DP Master U nits does not provide a direct interface to this type of medium. However, by using third party coup lers an interface between EIA RS-485 and optical fibre networks can be made.

Linear Bus Topology PROFIBUS-DP defines the use of the Linear Bus Networ k Topology. T he B us

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 stations - master and slave stations - per line segment. If more than 32 stations 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.

Setting up a Network

Section 2-4

Note Repeaters are devices which connect two segme nts. They do not have a sta-

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

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

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

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 bas ed 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 Cor e c ross sec t ion

0.34 mm

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

different cable characteristics. This Type B cable is no longer recommended for us e .

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.

Baud rate

(kbit/s)

9.6 1200 500 400

19.2 1200 1500 200

Note If the network must be extended beyond the range of the advised cable

length, the use of a fibre optic segment to cross the larger distance shoul d be considered.

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 stations with termination, it is recommended to always use plug connec tors 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 dat a communication between other stations.

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 c orrect functioning up to the highest baud rate, the bus cable must be terminated at both its ends.

A missing bus term ination can cause errors during data t ransfer. Problems can also arise if too many bus terminators are fitted, since each bus terminator represents an electr ical load and reduces the signal levels and thus the signal-to-noise ratio. Too many or missing bus terminators can also cause intermittent data transfer errors, particularly if the bus segment i s operated close to the specified limits for maximum numbers of stations, maximum bus segment length and maximum data transfer rate.

ensure proper operation at high baud rates, i.e. baud rates of 500 kbit/s and higher. Due to the capacitive load of the station and the resulting cable reflections, bus connectors must be provided with built-in seri es inductors, of 110 mH each, as shown in the figure on the left.

Installing the inductors applies to all stations on t he network, and not only to the stations 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-DP Master

Unit is a 9-pin male sub-D type, preferably encased in metal and h aving a facility to connect the shield of the cable to the c ase or to pin 1. The cable should be connected to the receive / transmit lines, pin 3 (B-line) and pin 8 (Aline).

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 term ination 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, pro vides an example of such a bus cable connector.

A standard 9-pin sub-D p lug can only be used if the P ROFIBUS-DP 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.

The two PROFIBUS data lines are designated A and B. There are no regulations on which cable core color should be connected to which of the two data terminals on each PROFIBUS device; the sole requirement is to ensure that the same core color is connected to the same terminal (A or B) for all stations throughout the entire system (across all stations and bus segments). The

Defining PROFIBUS-DP in the Software

PROFIBUS Organization recommends the following rule for data line color codes: PROFIBUS cables in general will use the colors 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.

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

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 ri ght up to the PROFIBUS device.

Ensure that the PLC an d the control cabinet in which it is mounted have the same ground potential by providing a large-area metall ic contact to ground, e.g. galvanized steel to ensure a goo d electrical connection. Grou nding 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:

• Deter mi ning loop resistance.

• Tes ting for correct bus termination.

• Deter mi ning the segment length and cable route.

• Other test methods.

• Example of an equipment re port in the PROFIBUS guideline.

2-5 Defining PROFIBUS-DP in the Software

Defining the Configuration After making the physical co nnections of the n etwork, the c onfiguration then

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

• Define the master(s).

• Assign slaves to their respective master(s).

• Assign slaves to groups for broadcast/multicast messages.

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

Downloading th e 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.

Section 3-2

Device Catalogue main components

The Device Catalogue is one of the main components in CX-Profibus. Its main functions are

• to maintain a list of installed DTM and GSD files.

• to provide convenient sorting and categorizing of the list.

• to allow updating the list, after installation of new DTMs or GSD files.

• to provide detailed information on selected DTMs

The main layout of the Device Catalogue is shown below.

DTM categories

Device name

Version number

Add selected device to the network

Invoking the Device Catalogue

The Device Catalogue window is opened by either selecting the icon in the CX-Profibus toolbar or by selecting the View - Device Catalogue m enu

option. Both options have toggle function: selecting one of them again will close the Device Catalogue.

DTM window layout The left window pane allows selection of specific groups of DTMs to be dis-

played. The right window pane lists the DTMs, which are installed on the PC and which are available for setting up a network. A selection of DTMs is made by selecting a specific group in the left window pane.

Note The list makes no distinction between normal DTMs and GSD files which

have been loaded through the Generic Slave Device DTM.

DTM list window The list items in the right window pane are described in the following table.

CX-Profibus

Section 3-2

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 de vice is defined by a GSD file, t he 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 DTM or the

GSD. If the device is defi ned by a GSD file, the Generic Sla ve 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 Vend or name is provided by the DTM or the GSD files.

Description

The left window pane allows selection o f spe cific groups of device DTM s with common attributes, e.g. Vendor name, Protocol type etc. If a group is selected, all device DTMs which belong t o that group wi ll be listed i n t he right window pane.

3-2-4 Updatin g th e Devi ce Cat alo gu e

If a new DTM has been installed, it will not automatically be included in the Device catalogue. In order to add newly installed DTMs to the list, the Device Catalogue must be updated by selecting the Update button at the b ottom of the window.

Section 3-2

Updating the Device Catalogue

Installing GSD files The Device Catalogue also allows the installation, i.e. copying of new GSD

Note 1. Updat ing the Device Catalog after copying GSD file can only be done if

Updating the Device Catalogue may take some time, depending on the amount of DTMs installed. A dialogue window with a progress bar will be shown during the update process. After updating the Dev ice Catalogue, it will be stored on hard disk. The next time CX-Profibus is started the updated list will be used.

After selecting the GSD file, and selecting the Open button in the File selection win dow, the GSD file will be copied to t he GSD file d irectory under CX-Profibus.

After copying the GSD file, a warning window will be displayed, indicating that the Device Catalogue needs to be updated. This can be accomplished by selecting the Yes button in the warning window.

there is a new project opened, i.e. with no DTMs allocated to the network. This is to prevent corruption of an existing network in case a GSD file is removed or replaced.

2. The Install GSD Files... option allows installation of more than one file at the same time.

3-2-5 Saving and Opening Proj ects

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 Fil e selection window, allowing the user to enter a file name.

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

CX-Profibus

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 th e Project file by the DTM itse lf.

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 constr ucted. However,

for performance reasons, the DTMs are not di rectly 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 the extension *.CPR will invoke CX-Profibus and open the selected file.

3-2-6 Adding Devices to the Network

The Unit goes to the OPERATE mode whenever the PLC

goes to the RUN / MONITOR mode.

The table below defines the behavior in case the PLC changes to PROGRAM mode.

Control Description

Keep Current Mode Unit keeps t he current mode if the PLC goes to PRO-

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 behavior in case an error occurs in one of the

allocated slave stations, which causes it to stop data exchange with the Master Unit. If Auto-C L EA R is enabled, the Unit will aut omatically transit ion to the CLEAR state and force all its allocated slave stations to the ‘safe’ state, i.e. all outputs are set to 0.

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

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

Section 3-3

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 behavior and timing on the PROFIBUS network. The Bus Parameters depend on the selected baud rate, cer tain slave communication parameters as well as the number of I/O data bytes exchanged between the Master Unit and each of the slave stations.

The required combination o f Bus Parameters is calculated by the program, based on the dependencies mentioned above. However, the us er can chan ge selected Bus Parameter manually if the application requires this.

!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 behavior.

Note When making changes to certain Bus Parameters, selecting the Optimize but-

tons, allows toggling between the optimized values and the changed values. Selecting an other baud rate after changing certain pa rameters, will reset the Bus Parameters to default values for the new baud rate.

Generic Slave Device DTM

3-4 Generic Slave Device DTM

Most of the current PROFIBUS-DP slave devices are supplied with a GSD file in order to allow a configurator to setup a configuration for that particular slave device. OMRON’s Generi c Slave Device DTM is provided to allow integration of the GSD file based conf iguration options in to an FDT Co ntainer application, l ike CX- Profibus.

The GSD files are stored in a separate sub-directory under CX-Profibus. Upon updating the Device Catalogue, the Generic Slave Device DTM will scan this sub-directory and present an entry in the Device Catalogue for each of the GSD files found.

Upon adding the GSD based slave device to the network, an instance of the Generic Slave Device DT M will be made in the PC me mory, which will re ad the GSD file contents. The instance of the Generic Slave Dev ice DTM will provide the User Interface necessary to make the settings for the associated slave device.

3-4-1 Configuration User Interface

Section 3-4

Opening the configuration DTM

The configuration DTM is opened by

• Selecting the slave DTM entr y in the Network Window, and double-clicking the left mouse button.

• Selecting the slave DTM in the Network Window, and right-clicking the mouse. From the context menu, select Configuration.

The slave DTM Configuration User Interface, which is displayed in the CXProfibus DTM window is shown below. The figure shows the User interface for an OMRON CJ1W-PRT21 PROFIBUS-DP Slave Unit. By default the Configuration tab is opened.

Generic Slave Device DTM

The Configuration User Interface for the Generic Slave Device DTM, contains three tabbed windows. Above these windows the Device, the Manufacturer, the GSD file and the Unit’s PROFIBUS ID number are displayed.

Section 3-4

Configuration Tab The Configuration tab contains the Device settings and the I/O Module Con-

figuration.

Device Settings The Device Settings contain the station address, i.e. the Unit’s PROFIBUS

address and the Watchdog time for the Unit. The station address is normally set automatically by the Master DTM, when the slave DTM is added to its tree. However, the User has the opportunity to change the address. The changed address will be transferred to the Master DTM.

Note In case a changed address is invalid, for example if there is already another

slave device with the same new address, the Master DTM will set the number back to its old value.

The Watchdog value is the value used by the slave device to monitor communication from the Master Unit. If no messages are sent to the slave by its Master within the Watchdog timeout time, the slave device will stop data exchange and switch back to the fail safe mode.

Module Configuration The I/O Module Configuration defines the I/O Data which the slave will be

exchanging with the Master Unit, when it is in data exchange mode. The upper window in the Configuration tab contains all possible modules, which are in the GSD file. The lower window holds all selected I/O modules.

The User has to select the m odules, which are associated with the physical configuration of the slave device. Selecting, i.e. copying the module from the upper window of the lower window can be done in several ways.

• Double-click the left mouse button on the selected module in the u pper window.

• Select the module in the upper window and click the Insert button or Append button. Insert will insert the module above the row selected in the lower window. Append will add the module to the end of the selected module list.

Note 1. The User can select multiple rows (in both windows) by simultaneously

holding the SHIFT or CTRL key on the keyboard and selecting the rows using the left mouse button.

2. The amount of I/O modules and data whi ch can be selected d epends on the slave device. The four rows of infor mation above the module display the maximum amounts as well as the selected totals.

Removing one or more selected modules from the list is done by

• double-clicking the left mouse button on the module in the lower window.

• selecting the module in the lower window and click the Remove button. In this case selecting multiple modules is also possible.

Generic Slave Device DTM

Section 3-4

Parameter Tab The Parameter tab lists all settings to b e made for the Parameter message.

The Parameter tab is shown below (Example shown is the Parameter tab for an OMRON CJ1W-PRT21 PROFIBUS-DP Slave Unit).

Common Parameters The PROFIBUS-DP parameter message contains a number of settings for the

slave device. It is transmitted to the slave device before the I/O Configuration message. In most cases a slave device required a block of Common Parameter settings, i.e. settings which apply to the whole device.

Module Parameters However, there are also more sophisticated - modular - devices which require

parameter settings per I/O module selected. The specific parameters blocks can be selected from the drop-down list at the top of the Parameter tab. In the figure above, the Common parameters are shown. This particular device does not support module parameters, so the parameters shown are the only ones.

The Parameter list consist of a left column containing the name of the Parameter and a right column containing the settings options. In order to change the parameter setting, double-click the row, with the left mouse button. Depending on the type of parameter and the selection options, either the field can be edited directly, or a dr op-dow n list with options w ill appe ar.

Note The parameter settings must be performe d carefully. Any faulty parameter in

the message and the slave device will in general reject th e message and it will not reach I/O data exchange with the Master.

The parameter values are by default displayed in Hexadecimal format. By checking the check box at the bottom, the values are converted to decimal values.

Group Tab In the Group tab the user can define to which group the slave device will

belong. This group definition is used to define multi-cast groups of slave device to which a Global_Control message can be transmitted. The window is shown below.

Generic Slave Device DTM

Sele cting the Grou ps The User can check the check boxes for each group the slave device will

belong to. The group setting is transferred to the slave device as part of the parameter message.

Section 3-4

3-4-2 Diagnostics User Interface

The Generic Slave Device DTM provides a Diagnostics User Interface to display diagnostics data sent by the slave dev ice to the PROFIBUS-DP Master Unit. In general a slave device can send two type of diagnostics.

Basic Diagnostics • Basic Diagnostics

The first six bytes of each diagnostic message sent by a slave device contain mandatory status and error flags. The flags are defined by the PROFIBUS standard. refer to a detailed overview of diagnostics. The basic diagnostics information is displayed in the Diagnostic tab of the Diagnostics User Interface.

Extended Diagnostics • Extended Diagnostics

Depending on the type of slave device, it may additionally send Extended diagnostic bytes in a format defined in the PROFIBUS standard. The Extended diagnostics usually contain device specific diagnost ics information. The Extended diagnostics information is displayed in the Extended Diagnostics tab of the Diagnostics User Interface.

Updating the Diagnostics The Diagnostics User Interface contains two tabbed windows. It also contains

an Update button, which will - when pressed - refresh the diagnostics data, by

When set, the slave station reports static diagnostics , i .e. the error event is serious enough that the diagnostics is continuously reported. No data exchange will be performed.

When set, the slave indicates that it requires a new parameter setting. The slave station is not in Data_Exchange with the Master Unit. The indicator remains ON as long as the slave device has not been parameterized successfully. The slave device has more diagnostics to report than it can fit i n to its transmission buffer.

Diagnostics information is being lost .

Section 3-4

Extended Diagnostics Tab

The Extended Diagnostic tab contai ns any extended diagnostics reported by the slave station. The figure below shows an example of Extended diagnostics.

The first row of the Extended diagnostics window contains the raw data as received from the slave station. Depending on the GSD file, it may provide text strings for each Extended diagnostics events entry, i.e. if the event occurs and the diagnostics information is received by the DTM, it can d isplay a text string in stead of onl y the raw bytes. This makes troubleshooting the device easier.

If the strings are not supported, the user must determ ine the event from the raw data byte s.

Overview of Word Allocations

4-1 Overview of W ord Allocations

The words shown in the following diagram are allocated according to the unit number setting. For each CPU Bus Unit, there are 25 words allocated in the CIO Area and 100 words allocated in the DM Area.

First word allocated in the CIO Area: n = CIO 1,500 + (25 x unit number) First word allocated in the DM Area: m = D30,000 + (100 x unit number)

Note The allocated DM words are not used by the PROFIBUS-DP Master Unit.

However, exchange of data to the allocated DM words is reser ved for future use, and it is therefore not recomm ended to use the allocated DM words for other purposes.

Overview of Word Allocations

4-1-1 CIO Area Word Allocations

Software switches, PROFIBUS-DP Master Unit status, and Slave Status data are allocated in the CIO Area a ccording to the unit number, as shown below. Software switches are bits used as commands from the PLC CPU to the PROFIBUS-DP Master Unit to enable executing Unit functions.

4-1-2 DM Area Word Allocations

The DM area words which are allocated for the PROFIBUS-DP Master Unit are not used, i.e. no data is exchanged between an allocated DM area and the Unit. However, the allocated area is reserved for use in a future extension of the Unit. Therefore, using this area for user data is not recommended.

4-2 Allocated CIO Area Words

For each CPU Bus Unit, the CS/CJ-series PLC allocates up to 25 words in the CIO area. Data is stored in the offset position defined by the uni t number and shown in the following figure, starting from the first allocated word to the Unit in the CIO Area. First word n = CIO 1500 + (25 x Unit number).

The C IO Wo rds contain two Reserved Words:

• CIO Word n+1 is reserved for future extension of switch functions. The Unit will alw ays set the b i ts i n th is Word to OFF.

• CIO Word n+3 is reserved for future extension of data to be transferred to the Unit.

These words are reserved for future use, and it is therefore not recommended to use them for temporary data storage by a User program. The other CIO Words are explained in the following sections.
