6 Conformance to EC Directives

6-1 Applicable Directives

•EMC Directives

• Low Voltage Directive

6-2 Concepts

EMC Directives

OMRON devices are designed so that they comply with the related EMC Directives 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 Directives (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 61000-6-2 EMI (Electromagnetic Interference): 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 EN 61131-2.

(Radiated emission: 10-m regulations)

Conformance to Shipbuilding Standards 7

6-3 Conformance to EC Directives

The CompoNet Master Units comply with EC Directives. To ensure that the machine or device in which a CompoNet Master Unit is used complies with EC Directives, the CompoNet Master Unit must be installed as follows:

1,2,3... 1. The CompoNet Master Unit must be installed within a control panel.

2. You must use reinforced insulation or double insulation for the DC power supplies used for the communications power supply and I/O power supplies.

3. CompoNet Master Units complying with EC Directives also comply with the Common Emission Standard (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.

1-1 CompoNet Networks

1-1-1 Overview

CompoNet Networks feature easy operation and installation in a componentlevel network connecting PLCs and on-site I/O.

The PLC and CompoNet Slave Units cyclically exchange I/O information through a CompoNet Master Unit, refreshing I/O in sync with the PLC scan.

Message communications can also be used from host computers or the CPU Unit of the PLC to read and write CompoNet Slave Unit data.

1-1-2 Overall System Configuration and Elements

A CompoNet Network is a remote I/O system that consists of the following elements.

CompoNet Networks Section 1-1

Communications Cables CompoNet Networks use Round Cable I, Round Cable II, Flat Cable I (DCA4-

4F10 Standard Flat Cable), and Flat Cable II (DCA5-4F10 Sheathed Flat Cable) for Communications Cables.

Master Unit The Master Unit manages the CompoNet Network and transfers I/O data

between the PLC and the Slave Units.

There is only one Master Unit per network. The Master Unit must be connected to the end of the trunk line.

Slave Units Some Slave Units receive output data from the Master Unit across the Com-

poNet Network and output it. Other Slave Units send data that has been input across the network to the Master Unit. There are two types of Slave Unit according to the I/O capacity of the Slave Unit.

• Word Slave Units: A Word Slave Unit is allocated 16 bits (i.e., 16 I/O points) in the I/O memory of the CPU Unit.

• Bit Slave Units: A Bit Slave Unit is allocated 2 bits (i.e., 2 I/O points) in the I/O memory of the CPU Unit.

Repeater Unit Using Repeater Units enables expanding network connections as follows:

• Extending the Communications Cable

• Increasing the number of nodes (Units)

• Creating long-distance T-branches from the trunk line and sub-trunk lines (See note.)

• Converting between different types of cable (round cable I, round cable II, Flat Cable I, and Flat Cable II)

A sub-trunk line downstream from a Repeater Unit can be connected with the same communications specifications (i.e., distances and number of Slave Units) as the trunk line.

Up to 64 Repeater Units can be connected per network (i.e., per Master Unit). When Repeater Units are connected in series from the Master Unit, up to two layers can be created.

Note The physical layer is not connected across a Repeater Unit. The

connection is thus different from a branch connection, which branches the same physical layer.

Terminating Resistors With a CompoNet Network, the Master Unit is located at one end of the trunk

line and a Terminating Resistor is connected to the other end of the trunk line. If Repeater Units are used, each Repeater Unit is treated like a Master Unit, i.e., Terminating Resistor is connected to the most remote end of the subtrunk line downstream from the Repeater Unit.

Note A Terminating Resistor reduces signal bouncing to stabilize com-

munications and must always be connected to the most remote end of the network lines below the Master Unit and each Repeater Unit. Always connect a Terminating Resistor to ensure the quality of the transmission path.

Trunk Lines and Branch Lines

The trunk lines and branch lines in a CompoNet Network are defined as follows:

• Trunk line: The transmission path between the Master Unit and the Terminating Resistor.

• Sub-trunk line: The transmission path between the Repeater Unit and the Terminating Resistor (when a Repeater Unit is used)

• Branch line: The transmission path created using a T-branch from the trunk line or sub-trunk line.

CompoNet Networks Section 1-1

• Sub-branch line: The transmission path created using a T-branch from a branch line. (T-branching is not possible from sub-branch lines.)

Note Due to differences in functionality, the same type of cable must be

used between the trunk line and a branch line, a sub-trunk line and a branch line, and a branch line and a sub-branch line. Different types of cable can be used between the trunk line and a sub-trunk line.

Branches There are two ways to create branch lines.

1) T-branch Connections

• T-branch connections using Flat Connectors (when Flat Cable I or Flat Cable II is used)

• T-branch connections using commercially available relay terminals (when round cable I or round cable II is used)

2) Multidrop Connections

• Multidrop connections using Flat Connectors and Multidrop Connectors (when Flat Cable I or Flat Cable II is used)

• Multidrop connections using Open Type Connectors (when round cable I or round cable II is used)

Note Flat Connectors can also be used to extend the Communications

Cable.

Communications Power Supply

This is the power supply for communications and internal operations for each Unit.

A commercially available 24-VDC power supply is used for communications and internal operations in each Unit.

One communications power supply can be connected for a trunk line or a subtrunk line. Communications power is supplied to the trunk line from the Master Unit and to a sub-trunk line from the Repeater Unit.

One power supply cannot be used to supply communications power to more than one line (i.e., to the trunk line and sub-trunk line or to two sub-trunk lines).

I/O Power Supply A commercially available 24-VDC power supply is used to power the I/O oper-

ations of the external I/O device connected to a Unit. It is connected to the I/O power supply terminal of the Unit.

1-1-4 Features of CompoNet Networks

Programless Communications

High-speed Multi-point Processing

Repeater Units for Greater Flexibility

With the use of only Round Cable I, Round Cable II, Flat Cable I and Flat Cable II cables, cyclic data exchange or remote I/O communications can be achieved between a Master Unit mounted in a PLC and multiple Slave Units.

Remote I/O communications for up to 2,560 I/O points can be achieved at approximately 1,000 points per millisecond (at 4 Mbps, see note). This enables configuring CompoNet Network systems to replace systems previously configured with Basic I/O Units.

Note Branch lines cannot be used at 4 Mbps. Slave Units with Cables

(i.e., Bit Slave Units) can thus not be used.

Easy Introduction

Remote I/O communications can be started merely by connecting the Master Unit and Slave Units with communications cables, setting the switches on the Master Unit, and turning ON the power to the Slave Units and PLC.

Repeater Units can be used in a network to enable the following network expansions.

• Extending the cable length

• Increasing the number of nodes

• Branching from the trunk line

• Changing the type of cable

Repeater Units can be used to extend up to two segment layers (called subtrunk lines) from the trunk line. Up to 64 Repeater Units can be connected per Master Unit and up to 32 Repeater Units can be connected to the trunk line.

Note Communications power is supplied to a sub-trunk line from the Re-

peater Unit.

Bit-level Distribution Slave Units with industry-standard e-CON connectors or clamping terminal

blocks can be used to distribute I/O at the bit level. This enables distributed control in distributed devices, such as sensors and other devices located over a wide area on conveyors or in warehouses.

Bit Slave Units are available in two types: IP20 and IP54.

Five Communications Modes According to Number of Nodes, I/O Points, and Allocated Memory

Data Exchange with Message Communications

Easy Maintenance with Complete System Monitoring Functions

There are five communications modes that can be used according to number of Slave Units, the number of I/O points, and the location of allocated memory. Memory can be allocated to Slave Units in the Special I/O Unit portion of the CIO Area or, if the CX-Integrator software settings are used, in any part of the CIO, DM, Work, and Holding Areas.

This enables efficient application of memory according to the size of the system.

Message communications can be used from the CX-Integrator running on a host computer or from the CPU Unit of the PLC to access Slave Units and Repeater Units on the CompoNet Network. This enables easily improving network and system maintenance.

The CompoNet Network is constantly monitored to enable confirming system safety by quickly isolating errors and checking communications status.

■ CX-Integrator

The CX-Integrator provides the following network functionality.

• Uploading the network configuration

• Editing and transferring software setting tables

CompoNet Networks Section 1-1

• Editing and transferring registration tables

• Setting Input Data Zero Clear Mode for when communications error occur

• Setting I/O Communications Manual Startup Mode

• Monitoring Master Unit status

• Monitoring the Master Unit error history

• Monitoring Slave Unit network participation status

• Setting and transferring Slave Unit parameters

• Monitoring Slave Unit information

• Managing files

• Managing hardware (EDS files)

■ Smart Slave Unit Functions

The Slave Units provide Smart Functions that can record various added-value information in addition to the ON/OFF signals (I/O data). This enables preventive system maintenance (including operation time monitoring and contact operation counter monitoring) and aids in faster system introduction (including communications power voltage monitoring and I/O power status monitoring). Settings are possible from either the CX-Integrator or through message communications.

■ Master Unit Detection of Network Participation, Errors, and Status

When a Slave Unit joins the network, a bit corresponding to the node address called a Participation Flag will turn ON. If a Slave Unit that has been participating in the network leaves the network, a bit corresponding to the node address called an Error Flag will turn ON.

Network status, such as communications errors and redundant Slave Unit node address, and Slave Unit diagnostic results are detected by the Master Unit and display on the seven-segment display on the front panel and reflected in the Status Flags.

■ Registration Tables

Tables of the Slave Unit that should be participating at each node (i.e., the node address and corresponding Slave Unit model number) can be registered from the CX-Integrator to verify the Slave Units actually participating in the network and prevent unregistered Slave Units from participating in the network. A monitoring time for registered Slave Unit participation after power is turned ON can also be set.

Remote I/O communications can be stopped until all registered Slave Units are participating and remote I/O communications can be started as soon as all registered Slave Units are participating (called Registered Slave Unit Participation Standby Mode).

■ Stopping Communications at Communications Errors

A DIP switch on the front of the Master Unit can be set to stop remote I/O communications when a communications error has occurred in any of the Slave Units.

■ I/O Communications Manual Startup Mode

I/O Communications Manual Startup Mode can be set from the CX-Integrator so that remote I/O communications are not started when the power is turned ON. Remote I/O communications will not start until the Remote I/O Communications Start Switch is turned ON in memory.

CompoNet Network Specifications Section 1-2

■ Communications Error Input Data Zero Clear Mode

Input Data Zero Clear Mode can be set from the CX-Integrator for communications error. If a communications error occurs for a Slave Unit in this mode, all input data for that Slave Unit will be cleared to zeros. This can be used to suppress triggering operations when communications errors have occurred in systems where ON input data signals are used as triggers for operation.

■ Communications Status on Master Unit Seven-segment Display

The seven-segment display on the front of the Master Unit can be used to check communications status.

The baud rate is normally displayed, but if an error occurs, the error code is displayed in hexadecimal and the error node address is displayed in decimal.

Automatic Baud Rate Detection

The Slave Units will automatically detect and use the baud rate set on the DIP switch on the Master Unit. Setting the baud rate is not necessary for any of the Slave Units.

1-2-3 Allocating Slave Units in the CPU Unit Memory Area by

Communications Mode Number

Slave Unit I/O information and status information is allocated in the Special I/O Unit memory area or a user-specified area of the CPU Unit to which the Master Unit is mounted.

The area is determined by the unit number of the Master Unit as a Special I/O Unit and by the communications mode number. The user specifies the communications mode number using the CX-Integrator. The bits used by Slave Units are determined by the node address for each Slave Unit.

The relationship between communications mode numbers, the number of connected nodes, and the number of points that can be controlled is described next.

Overview of Design Flow Section 1-4

1-4 Overview of Design Flow

Perform the following steps to design the system.

1. Determine the number of I/O points. ...Refer to 1-2 CompoNet Net-

Determine the number of I/O points in the entire system.

▼

2. Match up the I/O points with specific Slave Units.

Determine the specific Slave Unit for each input and output.

▼

3. Determine the number of nodes.

Determine how many nodes are to be connected.

▼

4. Determine the layout. ...Refer to SECTION 3 Wiring

• Determine the wiring form (trunk line-branch lines or unrestricted branching).

• Determine the wiring distances.

• Determine the method for providing communications and I/O power supplies to the Slave Units (with minimal wiring).

• Determine the type of cable to be used.

▼

5. Temporarily determine the communications mode number and the baud rate.

Note Branching is not possible at a baud rate of 4 Mbps, so Bit Slave Units with Flat

Cable cannot be used.

▼

6. Determine the communications cycle.

The communications cycle is determined from the communications mode number and the baud rate. (With communications mode 8, it also depends on the type and number of Slave Units.)

Determine whether the required I/O response time can be achieved at that baud rate.

▼

7. Consider using more than one Master Unit.

If the desired distance and communications cycle cannot both be achieved even after rechecking the communications mode number, the baud rate, and the use of Repeater Units, then use more than one Master Unit.

■ Remarks

Wiring Form

• When there is no branching, any combination of cable types and baud rates are supported.

• When there is a branch, Round Cable I, Round Cable II, Flat Cable I and Flat Cable II cables cannot be used at a baud rate of 4 Mbps. This means you cannot use a Bit Slave Unit with a pre-attached cable at 4 Mbps. When a Round Cable I cable is used at a baud rate of 1.5 Mbps, the trunk line and the sub-trunk line must be no longer than 30 m.

• When a branch line has a sub-branch line, Round Cable II, Flat Cable I, or Flat Cable II cables must be used either at a baud rate of 1.5 Mbps or

93.75 kbps.

Design and Operating Procedure Examples Section 1-6

Maximum Length for Trunk Lines and Sub-trunk Lines

• When the lines are 30 m or less: Any combination of cable types and baud rates is supported.

• When a distance longer than 30 m is required:

• Round Cable I: The baud rate must be 1.5 Mbps, with no branching. (The cable length can be up to 100 m.)

• Round Cable II, Flat Cable I, or Flat Cable II: The baud rate must be

93.75 bits/s. (The cable length can be up to 200 m when unrestricted branching is used.)

Design and Operating Procedure Examples Section 1-6

Types of Cables Flat Cable is used in this example, because IP20 Bit Slave Units are used and

the communications power supply is provided collectively through the communications cables.

Trunk Line-Branch Line Formation

Unrestricted Wiring Formation

Master Unit: The Master Unit does not necessarily have to be on one end of the network.

Slave Unit

Slave Unit Slave Unit

With this wiring formation, the trunk line is differentiated from branch lines.

There are restrictions on the number of branches and the number of Units that can be connected.

Master Unit: The Master Unit must be on one end of the networ k.

Only one level of branching is possible from the trunk line.

Tr unk line

Branch line

Slave Unit

Branch line

Slave Unit

Ter minating Resistor

With this wiring formation, there is no differentiation between the trunk line and branch lines.

There are no wiring restrictions as long as the total cable length does not exceed 200 m. There is also no limit on the number of branches.

There is no differentiation between a trunk line and branch lines, and there are no restrictions in branching as long as a maximum of 32 Slave Units and a total line length of 200 m are not exceeded.

Repeater Unit

3-2 CompoNet Network Wiring

A CompoNet Network requires wiring of following lines.

• Two communications signal lines: BDH (communications data high) and BDL (communications data low),

• Two communications power supply lines: one for communications, and the other for internal circuits of Slave Units. Terminals are BS+ (+ terminal of communications power supply) and BS power supply).

The wiring method depends on the cable type.

− (−terminal of communications

3-2-1 Round Cable I

• The two communications signal lines are connected in parallel between the Master Unit or a Repeater Unit and multiple Slave Units.

• A DCN4-TB4 Open Type Connector is used to connect the communications cable between the Master Unit or a Repeater Unit and a Slave Unit.

• The two communications power supply lines are connected to each Slave Unit. The supply lines must be different lines from the communications lines. The communications power supply lines supply 24-VDC communications power.

• The Master Unit and the connected Repeater Units are not supplied with power.

• A DRS1-T Terminating Resistor must be connected at the end of the network.

ble have been adjusted to the specific application of the conductor as listed in the table. Check the insulator colors, and use them only for the specified application.

Selecting Cable Types Refer to Types of Cables on page 24, and select applicable cables.

Using Different Cable Types

Cable Separation between Multiple CompoNet Network

All cables downstream from the Master Unit must be the same type. That means the same type of cable must be used for the trunk line and their branch lines; for sub-trunk lines and their branch lines; and branch lines and their sub-branch lines.

If a Repeater Unit is used, however, cables can be different upstream and downstream from the Repeater Unit, i.e., for the trunk line and sub-trunk lines, and for a sub-trunk line and another sub-trunk line. Refer to the following illustration.

Master Unit

Slave Unit

The same type of cable must be used.

Note Round Cable I, Round Cable II, Flat Cable I and Flat Cable II cables

are all treated as different types of cables.

When more than one CompoNet network uses Flat Cable I or II cables, electrical interference may disturb stable system operation. To prevent interference, do not bundle Flat Cables from different CompoNet networks. Instead, separate the Cables for one network by at least 5 mm from cables for other networks.
