6 Conformance to EC Directives

6-1 Applicable Directives

•EMC Directives

• Low Voltage Directive

6-2 Concepts

EMC Directives

OMRON devices that comply with EC Directives also conform to the related EMC standards so that they can be more easily built into other devices or the overall machine. 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 the OMRON devices that comply with EC Directives will vary depending on the configuration, wiring, and other conditions of the equipment or control panel on which the OMRON devices are installed. The customer must, therefore, perform the final check to confirm that devices and the overall machine conform to EMC standards.

Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:

EMS (Electromagnetic Susceptibility): EN 61131-2 and EN 61000-6-2 EMI (Electromagnetic Interference): EN 61131-2 and EN 61000-6-4

Low Voltage Directive

Always ensure that devices operating at voltages of 50 to 1,000 V AC and 75 to 1,500 V DC meet the required safety standards for the PLC (EN61131-2).

6-3 Conformance to EC Directives

The OMRON products described in this manual comply with the related EMC Directives. To ensure that the machine or device in which the products are used complies with EC Directives, the products must be installed as follows:

1,2,3... 1. The products must be installed within a control panel.

2. A DC power supply with reinforced insulation or double insulation that can maintain a stable output even if the input is interrupted for 10 ms must be used for communications power, internal power, and I/O power. The OMRON S82J-series Power Supply is recommended. (See note.)

3. Products complying with EC Directives also conform to the Emission Standards (EN 61131-2 and EN 61000-6-4). Radiated emission characteristics (10-m regulations) may vary depending on the configuration of the control panel used, other devices connected to the control panel, wiring, and other conditions. You must therefore confirm that the overall machine or equipment complies with EC Directives.

(Radiated emission: 10-m regulations)

Conformance to EC Directives 6

4. Conformance with the EC Directives was confirmed with a system configuration using I/O wiring lengths of less than 30 m.

Note Conformance with the EMC Directive was confirmed when using

the recommended power supply.

SECTION 1

Feature of EtherNet/IP Slave Units Section 1-1

1-1 Feature of EtherNet/IP Slave Units

1-1-1 Overview

EtherNet/IP is an industrial multi-vendor network that uses Ethernet components. The EtherNet/IP specifications are open standards managed by the ODVA (Open DeviceNet Vendor Association), just like DeviceNet.

EtherNet/IP is not just a network between controllers; it is also used as a field network. The EtherNet/IP Slave Unit have the following features.

High-speed, High-capacity Data Exchange through Tag Data Links

The EtherNet/IP protocol supports implicit communications, which allows cyclic communications (called tag data links in this manual) with EtherNet/IP devices.

The default settings for remote I/O communications with the PLC are the same as for previous Slaves, whereby real I/O is allocated for each node address. One difference with previous Slaves is that an area for Smart Slave status information can be allocated to the Smart Slaves within the IN Area of the Master. This is in addition to real I/O. (Settings are performed using the Network Configurator or explicit messages.)

Tag Data Link (Cyclic Communications) Cycle Time

Tag data links (cyclic communications) can operate at the cyclic period specified for each application, regardless of the number of nodes. Data is exchanged over the network at the refresh cycle set for each connection, so the communications refresh cycle will not increase even if the number of nodes is increased, i.e., the synchronicity of the connection’s data is preserved.

Since the refresh cycle can be set for each connection, each application can communicate at its ideal refresh cycle. For example, a processes interlocks can be transferred at high speed while the production commands and the status monitor information are transferred at low speed.

Note The communications load to the nodes must be within the Units’ al-

lowed communications bandwidth.

Note The CIP (Common Industrial Protocol) is a shared industrial protocol for the

OSI application layer. The CIP is used in networks such as EtherNet/IP, ControlNet, and DeviceNet. Data can be routed easily between networks that are based on the CIP, so a transparent network can be easily configured from the field device level to the host level.

The CIP has the following advantages.

• Destination nodes are specified by a relative path, without fixed routing tables.

• The CIP uses the producer/consumer model. Nodes in the network are arranged on the same level and it is possible to communicate with required devices whenever it is necessary. The consumer node will receive data sent from a producer node when the connection ID in the packet indicates that the node requires the data. Since the producer can send the same data with the same characteristics in a multicast (either multicast or unicast can be selected), the time required for the transfer is fixed and not dependent on the number of consumer nodes.

EtherNet/IP Slaves Section 1-2

1-1-2 Features

EtherNet/IP Slaves have the following features.

Common Features

Node Addresses Set Using Rotary Switches

Automatically Detected Baud Rate

I/O Power Status Monitor The I/O Power Status Monitor is used to detect whether the I/O power supply

Input Filter (Input Units Only)

Detection Functions (Standard Feature)

Node addresses are set using rotary switches, which are clearer than the previous DIP switch settings.

Smart Slaves do not require the baud rate to be set. The Smart Slave automatically operates at the baud rate of the switching hub.

is connected and provide notification in the Status Area. The Configurator or explicit messages can be used to read the information.

The input filter is used to read the input value several times during the set interval and remove irregular data caused by noise and switch chattering.

This function can also be used to create ON/OFF delays.

These settings are made by using the Network Configurator.

Detection results can be read by using explicit messages if the sensor shortcircuit/disconnected and external load short-circuit/disconnected detection functions are used. The error location can be rapidly specified and restored.

Features of Screw-less Clamp Terminals

Labor-saving Clamp Terminal Block

For I/O wiring, a screw-less clamp terminal block is provided. Wiring is reduced by the use of ferrules that can be easily inserted and then later removed by simply pressing a release button.

Features of Environment-resistive Terminals

Dust-proof and Waterproof Construction (IP67) for High Resistance to Environment

No Power Supply Wiring for Input Devices

The environment-resistive construction enables usage in locations subject to oil and water splashes (IP67). An environment-resistive box is not required, enabling greater downsizing and reducing wiring labor.

Power for communications, internal circuits, and input devices is shared, making wiring necessary only for the communications power supply.

1-2 EtherNet/IP Slaves

The EtherNet/IP Slaves are classified into the following categories.

• General-purpose Slaves Slaves with digital I/O functions using standard connectors for communications cables.

• Environment-resistive Slaves Slaves with I/O functions using round waterproof connectors for communications cables.

4-2 Screw-less Clamp Terminals

The screw-less clamp terminal has a structure designed for clamping to a terminal block. It is a reduced-wiring, labor-saving Slave that can make wiring easy by simply inserting ferrules (with sleeves). The Unit and terminal block can be detached, making it possible to replace the Unit in the event of a failure without removing the wiring.

A detection function is also provided to help quickly discover short-circuits and disconnections for sensors or other devices.

4-2-1 Wiring to a Screw-less Clamp Terminal Block

Screw-less clamp terminals provide clamp-type terminal blocks that allow wiring without screws. When connecting a sensor or an external device, a ferrule must be attached to the cable for the sensor or device. The following ferrules are applicable.

Status Areas Section 5-1

5-1 Status Areas

An Environment-resistive Slave Unit has two internal status areas: the Generic Status Area and the I/O Status Area. The status flags in these areas are turned ON and OFF based on the threshold values set by the user for each function in that Unit.

5-1-1 Generic Status Area

The Environment-resistive Slave Unit's Generic Status Area contains the following 16 bits. These bits indicate minor errors in the Unit.

6-1 Functions Common to All Slave Units

This section describes the functions common to all EtherNet/IP Slave Units and the procedures for using these functions.

6-1-1 Automatic Baud Rate Detection

Description The EtherNet/IP Slave Units are automatically set to the same baud rate as

the hub. It is not necessary to set the baud rate separately for any Slave Unit.

The baud rate is set when communications is established with the hub after the power is turned ON. The baud rate setting is stored in memory until the power is turned ON again or until the Master Unit baud rate setting is changed.

6-1-2 Hold/Clear Outputs

Description Output Units can be set to hold or clear outputs when an error occurs.

Procedure Using Network Configurator

1,2,3... 1. Turn ON the power to the EtherNet/IP Slave Unit.

2. Double-click the icon of the Slave Unit to set in the Network Edit Device Parameters Window to open the Configuration Window. (Alternatively, rightclick the icon and select Parameters - Edit from the pop-up menu.)

3. The fault action (holding or clearing an output for a communications error) will be displayed for each output in the Fault Action Setting Group. Select Hold Last State or Clear Data for the terminals and then click the OK But- ton.

Clear Clears all output data from the Master Unit to 0 when a communica-

tions error occurs.

Hold Holds all output data from the Master Unit at its current status when a

communications error occurs.

6-1-3 I/O Power Status Monitor

Description Outputs can be set to be held or cleared when an error occurs in the Output

Unit.

Status Areas

6-1-4 Input Filter (Input Units Only)

Description An input value is read more than once during a set time interval. The input

value can be set to be enabled only when all the read values are the same. This function operates for all input points in one Slave Unit.

The following settings are possible: No delay (no filter), or 4, 8, 16, 32, 64, 128, or 256 ms.

OFF-ON Delay When the input data turns ON, the input data is read 4 times at a set time (1/4

of the time setting). The internal input data turns ON only when all four values are ON. The ON timing is delayed by the value of the input time constant.

4 3

The internal input

data turns ON because the read input data was ON all 4 times.

OFF

Input data

OFF

The internal input data

remains OFF because the read input data was not ON all 4 times.

ON delay (= input filter time)

ON-OFF Delay When the input data turns OFF, the input data is read 5 times at a set interval

(1/5 of the OFF response time setting). The internal input data turns OFF only when all values are OFF. The OFF timing is delayed by the value of the OFF response time.

This function can also be used to implement an OFF delay.

To enable reading pulses shorter than the communications cycle time, set the OFF response time to a value longer than the communications cycle time. (The input may remain ON if the input pulse interval is too short.)

2. Double-click the icon of the Slave Unit to set in the Network Configuration Window to open the Edit Device Parameters Window. (Alternatively, rightclick the icon and select Parameters - Edit from the pop-up menu.)

3. Select an input in the Input Point Group Setting Group and set the Off-On Delay or On-Off delay from the pull-down menu.

Functions Common to All Slave Units Section 6-1

6-1-5 Power Short-circuit Detection (Input)

Description This function monitors the sensor power supply current. If the current is

50 mA or higher per input contact, a power short-circuit is detected.

The Slave Unit I/O indicator can be used to check whether a power short-circuit has been detected. When a power short-circuit is detected, a flag in a status area in the Slave Unit turns ON to notify the Master Unit. The notification details can be read using explicit messages. When the cause of the short-circuit is removed, the Slave Unit is automatically reset, and the power output to the connector that had the short-circuit is turned ON again.

Setting Using the

Refer to bit 4 in 4-1-1 Generic Status Area and to 4-1-2 I/O Status Area.

Status Areas

6-1-6 Load Short-circuit Detection (Output)

Description This function monitors the load current for the output section and detects an

load short-circuit if the current per contact (or common) exceeds a specific value. When a load short-circuit is detected, all Unit outputs are turned OFF to prevent damage to the Unit's output circuits.

The I/O power for the Unit turns OFF if a short-circuit is detected for even just one of the contacts being used.

When a load short-circuit is detected, a flag in a status area in the Slave Unit turns ON to notify the Master Unit. The notification details can be read using explicit messages.

When the cause of the short-circuit is removed, the Slave Unit is automatically reset, and the power output to the connector for which the short-circuit was detected is turned ON again.

Checking Using the Status Areas

Refer to bit 4 in 4-1-1 Generic Status Area and to 4-1-2 I/O Status Area.

Problem Cause and possible corrections

MS indicator is lit red. • The Slave Unit is malfunctioning. Replace the Slave Unit.

MS indicator is flashing red.

The NS indicator lights red without flashing green.

• The rotary switch or other setting is illegal. Check the switch settings then restart the Slave Unit.

• There is an error in the Slave Unit's EEPROM memory data. To restore the default setting, set the rotary switches to FF hex, cycle the power supply, and then set the rotary switches to 00 hex. Replace the Slave Unit if the MS indicator keeps flashing red even after the data has been returned to the default settings.

Check the following item and then restart the Slave Unit.

• Check the node addresses of all nodes and change the settings as required so that each node has a unique node address.
