6 Conformance to EC Directives
6-1 Applicable Directives
•EMC Directives
• Low voltage directive
6-2 Concepts
OMRON units complying with EC Directives also conform to related product
standards making them easier to incorporate in other units or machines. The
actual products have been checked for conformity to product standards.
Whether the products conform to the standards in the system used by the
customer, however, must be checked by the customer.
Product 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 product standards.
A Declaration of Conformity for the GRT1-PRT PROFIBUS Communication
Unit can be requested at your nearest OMRON representative.
6-3 Conformance to EC Directives
PROFIBUS units should be installed as follows, for the complete configuration
to meet the EC directives:
1,2,3... 1. The units are designed for installation inside control panels. All units must
be installed within control panels.
2. Use reinforced insulation or double insulation for the DC power supplies
used for the communication power supply, internal circuit power supply,
and the I/O power supplies.
3. The GRT1-PRT PROFIBUS Communication Unit product meets the generic emission standard. However as EMC performance can vary in the final installation, additional measures may be required to meet the
standards. It should therefore be verified that the overall machine or device
also meets the relevant standards. You must therefore confirm that EC directives are met for the overall machine or device, particularly for the radiated emission requirement (10 m).

Unit. The figure below shows a typical I/O configuration.
SmartSlice I/O configurations can be very compact, consisting of only a few
I/O points, but they can also be extended, to up to 64 I/O slices. The slice configuration can also be subdivided over two or more blocks using local extension units and extension cables, as shown in the figure above.

GRT1-PRT PROFIBUS Communication Unit
Section 1-2
1-2 GRT1-PRT PROFIBUS Communication Unit
1-2-1 Features
The GRT1-PRT PROFIBUS Communication Unit for SmartSlice I/O controls
data exchange between the PROFIBUS DP-V1 Master and SmartSlice I/O
Units over the PROFIBUS DP network. For an overview of the PROFIBUS
technology refer to Appendix A PROFIBUS Technology.
Manage Multiple
SmartSlice I/O Units as
One Slave
A single PROFIBUS Communication Unit with up to 64 connected SmartSlice
I/O Units can be managed as a single slave device from the PROFIBUS DPV1 Master.
I/O Data Exchange Cyclic I/O data exchange is used to exchange I/O data between the PROFI-
BUS Master and SmartSlice I/O Units through the PROFIBUS Communication Unit. In addition to I/O data, various status information in the PROFIBUS
Communication Unit as well as in the individual I/O slices can be accessed
from the PROFIBUS DP-V1 Master Unit.
Simplified Startup The PROFIBUS Communication Unit can be set up easily, just by wiring the
Unit, setting the PROFIBUS station address on the Unit’s rotary switches, and
making simple DIP switch settings.
The Unit’s configuration is read automatically when the power is turned ON
and I/O is also automatically allocated in the SmartSlice I/O Units. It is not
necessary to make any settings with a special Programming Device.
Simplified I/O Wiring All of the SmartSlice I/O Units that connect to a PROFIBUS Communication
Unit are equipped with screw-less clamp terminal blocks. Wiring to external
I/O is accomplished just by inserting the wire into the terminals, eliminating
the need to tighten terminal screws.
Table Registration The configuration of the SmartSlice I/O Units (mounting order and I/O size)
connected to a PROFIBUS Communication Unit can be registered in a table
simply by switching a pin on the PROFIBUS Communication Unit’s DIP
switch. Once the table has been registered, the actual configuration is compared to the registered configuration each time that the power is turned ON. If
the configuration does not match, a status flag can be turned ON in the
PROFIBUS DP-V1 Master to indicate the error.
Communication Error Log
Monitor
The communication error log in the PROFIBUS Communication Unit can
record the four most recent communication errors in the PROFIBUS DP network and the 64 most recent SmartSlice I/O Unit errors. The communication
error information (communication error cause code and communication power
supply voltage when error occurred) can be read with an explicit message
command or from the Configurator.
Online Replacement of I/O
Units
The SmartSlice I/O Unit’s circuit section can be removed, so it is not necessary to turn OFF the power to replace a Unit. Communication can be maintained in the remaining (connected) Units.
Parameter Backup and
Restore
Before replacing a SmartSlice I/O Unit for maintenance, the parameter data
set in the I/O Unit can be backed up in the PROFIBUS Communication Unit
by switching a pin on the Communication Unit’s DIP switch. After the I/O Unit
has been replaced, another DIP switch operation can be used to select the
mode that automatically writes the backed-up parameter data to the appropriate Units.

GRT1-PRT PROFIBUS Communication Unit
Section 1-2
Automatic Baud Rate
Recognition
The PROFIBUS Communication Unit automatically detects the Master’s communication baud rate, so it is not necessary to set the baud rate. (If the Master’s baud rate has been changed, the PROFIBUS Communication Unit must
be turned OFF and then ON again to change its baud rate.)
1-2-2 System Configuration
The PROFIBUS Communication Unit connects to the Master by a network
cable and it connects to the SmartSlice I/O Units by directly coupling the Units
with slide connectors.
I/O Data Exchange The I/O Unit data in the PROFIBUS Communication Unit is shared with the
Master’s Input and Output Areas through the PROFIBUS DP network. The I/O
Units’ data is collected in the PROFIBUS Communication Unit and exchanged
with the Master asynchronously.
Messaging Services The GRT1-PRT PROFIBUS Communication Unit also supports messaging
services, allowing the user to send acyclic message commands addressed to
the GRT1-PRT Unit or individual SmartSlice I/O Units.
Note Always install an End Unit on the last I/O Unit in the system.

1-3 GRT1-PRT Configuration
PROFIBUS Configuration
Means
The PROFIBUS DP Master Unit requires a configuration before it can
exchange I/O data with any of its slave devices. For this configuration information on the slave device must be available. OMRON provides two means
to facilitate Master Unit configuration.
•A GRT1-PRT DTM
• A GRT1-PRT GSD file
GRT1-PRT Configuration
DTM
The GRT1-PRT DTM is an executable component, provided by OMRON,
which requires an FDT Container program like OMRON’s Cx-Profibus (refer
also to Appendix A-9 FDT/DTM Technology). The DTM runs inside this FDT
Container and provides its own User Interfaces. It can access GRT1-PRT and
SmartSlice I/O Unit data through the PROFIBUS Master unit and present that
to the user. It can also save the settings, using the features of the FDT Container program.
The GRT1-PRT DTM, provides the user with the following features.
• Parameter configuration
• I/O Configuration
• Configuration of individual SmartSlice I/O Units
• Monitoring of the SmartSlice I/O System
Note In order to configure individual SmartSlice I/O Units, the PROFIBUS Master
Unit must support PROFIBUS DP-V1, Class 2 functionality. The OMRON
CS1/CJ1W-PRM21 PROFIBUS Master Units support this functionality as of
revision 3.

GRT1-PRT Configuration
Section 1-3
GRT1-PRT Parameter
Configuration
The PROFIBUS Parameter User Interface allows the user to set operational
parameters for the communication between the PROFIBUS Master and the
GRT1-PRT. The User Interface provides entries to set
• the device address (i.e. defining it for communication)
• the PROFIBUS group allocation for the GRT1-PRT.
• the FINS fragment length, used in acyclic communication.
• Specific PROFIBUS Master Unit behaviour with respect to this slave
device.
GRT1-PRT I/O
Configuration
The I/O Configuration User Interface allows the user to define the configuration of SmartSlice I/O Units attached to the PROFIBUS Communication Unit.
It also allows the user to make parameter settings for individual SmartSlice
I/O Units.
The I/O Configuration is used by the PROFIBUS Master Unit when mapping
the I/O data of individual SmartSlice I/O Units on to the PLC memory areas. It
is also sent by the PROFIBUS Master Unit to the GRT1-PRT for verification
when establishing communication. The I/O Configuration sent by the Master
Unit must match the physical configuration attached to the GRT1-PRT
PROFIBUS Communication Unit, in order to proceed with I/O data exchange.
Monitoring the SmartSlice
I/O System
The Monitoring User Interfaces allows the user to read information from individual SmartSlice I/O Units. It also provides a means to read the Error Log of
the GRT1-PRT PROFIBUS Communication Unit.
Configuration via GSD File The GSD file concept is the older, and consequently more widely used means
of configuration. The GSD file for the GRT1-PRT is a text based file, which
contains all options required to configure a PROFIBUS Master Unit. The file
can be loaded by the configuration software of the Master Units, which will
then present the information to the user to allow the appropriate selections to
be made.
The drawback of the GSD file is that- unlike the GRT1-PRT DTM - it only provides setting options for PROFIBUS DP and PROFIBUS DP-V1. The GSD file
does not provide the means to initiate parameter data transfer via PROFIBUS
DP-V1 Class 2 messages. These have to be programmed in the Master Unit it
self.
Third-Party Master Units The GSD file for GRT1-PRT can be used to configure most third-party Master
Units. The GRT1-PRT GSD file contains all the necessary parameters to
allow the user to configure the Master Unit for I/O data exchange.
Note 1. The GRT1-PRT DTM can also be used in third-party configuration soft-
ware provided that this software supports the FDT/DTM concept.
2. With the Cx-Profibus FDT Container OMRON also provides a Generic
Slave DTM, an FDT/DTM interface between the FDT Container program
and GSD files. Alternatively, this DTM can be used to setup a Master Unit,
using the GRT1-PRT GSD file. This Generic Slave DTM however, does
not provide the means to initiate PROFIBUS DP-V1 messages.
Downloading the
Configuration
After setting up the configuration, it must be downloaded to the PROFIBUS
Master Unit. The download process depends on the Master Unit used.

Basic Operating Procedure
Section 1-4
1-4-2 Preparations for Use
The following procedure shows the basic steps required before using the
PROFIBUS Communication Unit and the SmartSlice I/O Units.
Initial Setup Procedure
1,2,3... 1. Mount the GRT1-PRT Unit and the SmartSlice I/O system on the DIN rail
The maximum number of SmartSlice I/O Units can be 64.
2. Wire the SmartSlice I/O Units and the GRT1-PRT Unit’s power supply.
3. Wire the PROFIBUS network, to connect the Unit to the PROFIBUS Master Unit.
4. Set the rotary switches on the front of the GRT1-PRT to the desired
PROFIBUS address.
5. Turn ON the power to the Unit and the I/O.
6. Turn ON (from OFF to ON) DIP switch 1 on the front of the PROFIBUS
Communication Unit. When switch 1 is turned ON, the existing SmartSlice
I/O Unit configuration (connection order and I/O size) is registered in the
PROFIBUS Communication Unit as a registered table. After the table is
registered, leave pin 1 ON to enable the table.
Note The next time the power is turned ON, the actual SmartSlice I/O Unit configu-
ration at power on is automatically compared to the registered table. Any
SmartSlice I/O Units that do not match the registered table (connection order
or I/O size) will not participate in I/O communication. I/O communication will
start with the other SmartSlice I/O Units.
Configuration Procedure Use the following procedure to configure the PROFIBUS Master Unit for com-
munication with the PROFIBUS Communication Unit, using the Cx-Profibus
FDT Container program and the GRT1-PRT DTM:
1,2,3... 1. In Cx-Profibus, create a network and define the parameters and I/O con-
figurations for the PROFIBUS Master Unit settings and the allocated slave
devices. Determine the baud rate and the bus parameter setup. Make sure
that the “Go to OPERATE mode “option is selected, to force the Unit to OPERATE mode upon a PLC mode change to RUN / MONITOR mode.
2. Download the network configuration to the PROFIBUS Master Unit. After
downloading the configuration, Cx-Profibus will restart the PROFIBUS DP
Master Unit.
3. After restarting the PROFIBUS DP Master Unit it will automatically start
communication.
