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.

xvii

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).

SmartSlice I/O Units

Up to 64 SmartSlice I/O Units can be connected to one PROFIBUS

Communication Unit (Up to 1,024 inputs or outputs can be connected)

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.

The GRT1-Series of SmartSlice I/O Units and Communication Units is constantly being expanded with new Units. Refer to the latest revisions of the

GRT1 Series SmartSlice I/O Units Operation Manual (W455) and the GRT1DRT DeviceNet Communication Unit Operation Manual (W454) for currently available units in the GRT1-Series.

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.

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.

Cyclic I/O data exchange is used to exchange I/O data between the PROFIBUS 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.

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.

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.

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.

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.

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.

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.

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.

PROFIBUS Configuration

Means

GRT1-PRT Configuration

DTM

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

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.

Note

Downloading the

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.

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.

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.

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 thatunlike 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.

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.

1.The GRT1-PRT DTM can also be used in third-party configuration software 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.

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 configuration 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 communication 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 configurations 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.
