This manual provides information for programming and operating the Unit. Be sure to read this manual before attempting to use the Unit and keep this manual close at hand for reference during operation. Be sure this manual is delivered to the persons actually using the CompoNet Slave Units and Repeater Units.

!WARNING It is extremely important that a PLC and all PLC Units be used for the speci-

fied purpose and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult with your OMRON representative before applying a PLC System to the above-mentioned applications.

3 Safety Precautions

!WARNING Do not attempt to take any Unit apart and do not touch the interior of any Unit

while the power is being supplied. Also, do not turn ON the power supply while the cover is open. Doing any of these may result in electric shock.

!WARNING Do not input voltages or currents exceeding the rated range to the Unit.

Exceeding the rated range may cause Unit failure or fire.

Operating Environment Precautions 4

!WARNING Provide safety measures in external circuits (i.e., not in the Slave Units),

including the following items, to ensure safety in the system if an abnormality occurs due to malfunction of the PLC or another external factor affecting the PLC operation. (“PLC” includes CPU Units, other Units mounted in the PLC, and Remote I/O Terminals.) Not doing so may result in serious accidents.

• Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must be provided in external control circuits.

• The PLC will turn OFF all outputs when its self-diagnosis function detects any error or when a severe failure alarm (FALS) instruction is executed. As a countermeasure for such errors, external safety measures must be provided to ensure safety in the system.

• The PLC outputs may remain ON or OFF due to deposits on or burning of the output relays, or destruction of the output transistors. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the system.

• When the 24-VDC output (service power supply) is overloaded or shortcircuited, the voltage may drop and result in the outputs being turned OFF. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the system.

!WARNING The CPU Unit refreshes I/O even when the program is stopped (i.e., even in

PROGRAM mode). Confirm safety thoroughly in advance before changing the status of any part of memory allocated to I/O Units, Special I/O Units, or CPU Bus Units. Any changes to the data allocated to any Unit may result in unexpected operation of the loads connected to the Unit. Any of the following operation may result in changes to memory status.

• Transferring I/O memory data to the CPU Unit from a Programming Device.

• Changing present values in memory from a Programming Device.

6-2 Concepts

EMC Directives

The OMRON products described in this manual are designed so that they individually 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 note). Whether the products conform to the standards in the system used by the customer, however, cannot be checked by OMRON and 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

(Radiated emission: 10-m regulations)

Low Voltage Directive

Always ensure that devices operating at voltages of 50 to 1,000 VAC and 75 to 1,500 VDC meet the required safety standards.

Applicable standard: EN 61131-2

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.

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.

1-1 Features of CompoNet Slave Units

1-1-1 Overview

CompoNet Slave Units do not simply input and output ON/OFF signals, they can also collect a variety of information that can improve equipment operating rates.

They can also be used to build maintenance systems separate from control systems. Coexisting control and maintenance systems can contribute to reducing equipment startup time, recovery time after problems, and preventative maintenance of equipment.

■ Control System:

For remote I/O communications with the PLC, I/O is allocated for each node address by default. In addition, Slave Unit status information other than I/O is allocated in an input area in the Master Unit. The allocation can be set using the CX-Integrator or explicit messages.

■ Maintenance System:

Slave Units can store several kinds of equipment data. This data can be read from or written to the Slave Unit’s memory using the CX-Integrator or by sending explicit messages from the Master Unit (PLC) to the Slave Unit.

1-1-2 Features of CompoNet Slave Units

CompoNet Slave Units have the following features.

Main Features

The functions that can be used depend on the type of Slave Unit. For details, refer to 1-1-3 CompoNet Slave Unit Functions.

Operation Time Monitor The Slave Unit can quickly measure the ON/OFF timing of input and output

contacts without relying on the ladder program. Contact types (IN - OUT, OUT

- IN, IN - IN, OUT - OUT) and trigger patterns (ON

→ OFF, OFF → ON, ON →

ON, OFF → OFF) can be freely combined for measurement. A time can be set in the Slave Unit memory to enable notification of the status when the measured time exceeds the set time.

This data can be set or read by using the CX-Integrator.

Contact Operation Monitor

The number of times each input contact or output contact is turned ON can be counted at a sampling frequency of 50 Hz maximum and stored. A value can also be set in the Slave Unit to enable notification of the status if the number of contact operations reaches the set value.

This data can be set or read by using the CX-Integrator.

Note The contact operation monitor and the total ON time monitor can-

not both be used for the same contact at the same time.

Total ON Time Monitor The total ON time of sensors, relays, and other devices are stored in the Slave

Unit memory. A value can also be set in the Slave Unit to enable notification of the status if the total time reaches the set value.

These values can be set or read by using the CX-Integrator.

Note The total ON time monitor and the contact operation monitor can-

not be used at the same time for the same contact.

Automatic Baud Rate Detection

The baud rate is automatically set to the same baud rate as the Master Unit; therefore, there is no need to set the baud rate of the Slave Units.

Page 26

Features of CompoNet Slave Units Section 1-1

Unit Conduction Time Monitor

The total ON time of the Slave Unit's internal circuit power supply can be stored. This value can be read using the CX-Integrator or explicit messages. A value can also be set in the Slave Unit to enable obtaining notification of the status if the total time reaches a set monitor value.

This data can be read or written by using the CX-Integrator.

Naming Units The user can set any name for each Unit as a comment. The names are

stored in Slave Unit memory. This data can be read or written by using the CX-Integrator.

Naming Connected Devices

Any name can be set for each I/O contact (e.g., sensor or valve) connected to a Slave Unit. The names are stored in Slave Unit memory.

This data can be read or written by using the CX-Integrator.

Network Power Voltage Monitoring

The network power supply voltage (present, maximum, and minimum values) can be stored in the Slave Unit memory. A monitor voltage can also be set in the Slave Unit to enable notification of the status if the voltage drops to the preset value.

These values can be set or read by using the CX-Integrator.

I/O Power Status Monitor The I/O power status monitor function checks if the I/O power is ON or not,

and provides notification in a status area. This data can be checked by using the CX-Integrator.

Communications Error History Monitor

The previous four error records (communications error codes and the power voltage when the error occurred) can be held in the Slave Unit memory.

This data can be read by using the CX-Integrator.

Input Filters The Slave Units read input values multiple times during the set period to elim-

inate the effect of switch chattering and data omissions caused by noise. An ON delay or OFF delay can also be implemented by using this function.

These settings are made by using the CX-Integrator.

Communications Error Output Setting

The output value when a communications error occurs can be set for each word of an Output Unit.

These settings are made by using the CX-Integrator.

Preventing Malfunctions Caused by Inrush Current at Startup

This function holds inputs from when the power is turned ON until the Unit stabilizes, i.e., inputs are not received while the I/O power is OFF and for 100 ms after the I/O power is turned ON. This contributes to eliminating input errors caused by inrush current when the I/O power is turned ON.

These settings are made by using the CX-Integrator.

Power Short-circuit Detection

The I/O power current is monitored. If an excessive current is detected, it is assumed that a power short-circuit has occurred and the sensor power output is turned OFF forcibly.

The status can be checked by using the LED indicators on the Slave Unit or by using the CX-Integrator.

Load Short-circuit Detection

The output load current is monitored. If an excessive current is detected, it is assumed that an load short-circuit has occurred and the output is turned OFF forcibly to prevent damage to the Unit's output circuit.

The status can be checked by using the LED indicators on the Slave Unit or by using the CX-Integrator.

Removable Terminal Block The terminal block can be removed.

Page 27

Features of CompoNet Slave Units Section 1-1

Expansion Using Expansion Units

One Expansion Unit can be added to a Digital I/O Slave Unit (with 2-tier terminal block and 16 points). This extends the range of possible system configurations by making it possible to expand to a variety of I/O combinations, e.g., 16 inputs and 8 outputs or 24 inputs (16 inputs + 8 inputs).

Scaling Converted data can be scaled to any value by the user. Ladder program cal-

culations for the Master Unit are not required if the scaling function is used with the Slave Unit. The offset compensation function can also be used to offset scaled values.

These settings are made by using the CX-Integrator.

Last Maintenance Date (Maintenance Function)

The date that maintenance was performed can be written in the Slave Unit by using the CX-Integrator.

Cumulative Counter The cumulative counter function calculates the integral time for input (or out-

put) analog values and reads the cumulative value. Monitor values can be set in Units. If the cumulative counter value exceeds the set monitor value, the Cumulative Counter Monitor Flag in general status turns ON.

These values can be set and read by using the CX-Integrator.

Moving Average An Analog Input Unit or Temperature Input Unit can calculate the moving aver-

age of the last eight inputs and use it as the converted data. Smooth input values can be obtained by averaging the inputs if there are rapid fluctuations in the input.

Settings for averaging are made by using the CX-Integrator.

Setting the Number of AD Conversion Points

The conversion cycle is 4 ms max. when using all 4 analog inputs. The AD conversion cycle can be made faster if fewer AD conversion points are used.

Rate of Change Calculations

You can find the rate of change during the set data sampling cycle for the input value to an Analog Input Unit or Temperature Input Unit.

The rate of change settings are made by using the CX-Integrator.

Comparator The input to an Analog Input Unit or Temperature Input Unit or the calculated

data for a Unit can be compared with alarm settings (upper upper limit, upper limit, lower limit, and lower lower limit) and the result stored in the Analog Status Flags. The Normal Flag (pass signal) turns ON for values that are in set range.

The alarm settings are made by using the CX-Integrator.

Peak/Bottom Hold The peak/bottom hold function holds the maximum (peak) or the minimum

(bottom) input value to an Analog Input Unit or Temperature Input Unit. The maximum (peak) or minimum (bottom) value can be compared with an alarm set value and used to turn ON an alarm flag as status data. This is called the comparator function.

The peak/bottom hold settings are made by using the CX-Integrator.

Top/Valley Hold The top/valley hold function holds the top or valley input value to an Analog

Input Unit or Temperature Input Unit. The Top/Valley Detection Timing Flag can be used to check when top and valley values were detected. The top and valley values can be compared with an alarm set value and used as status data to turn ON alarm flags (comparator function).

The top/valley hold settings are made by using the CX-Integrator.

Page 28

Features of CompoNet Slave Units Section 1-1

Disconnected Line Detection

With Analog Input Units, the Disconnected Line Detection Flag for each input can be used in the Master Unit to check whether the analog input lines (for voltage inputs or current inputs) are disconnected for analog inputs that are enabled under the setting of the number of AD conversion points.

This function is supported only when the input range is 1 to 5 V or 4 to 20 mA. With Temperature Input Units, disconnections can be detected for each sensor input. The status can be checked at the Master Unit using the Disconnected Line Detection Flag.

User Adjustment The user adjustment function can be used to compensate offsets in input (or

output) values that occur due to the features of or connection method used for input or output devices to adjust the input (or output). The conversion line is adjusted at two points: 0% and 100%.

The adjustments can be made by using the CX-Integrator.

Top/Valley Count With Temperature Input Units, the maximum or minimum number of times the

top or valley value is reached can be counted for an application that has fixed cycles of temperature changes. Explicit messages can be used to see if the number of cycles has exceeded a monitoring set value.

The settings are made by using the CX-Integrator.

Temperature Range Total Time Count

With Temperature Input Units, the length of time that the temperature input value is within a user-set temperature range can be measured in seconds. Explicit messages can be used to see if the measured time has exceeded a monitoring set value.

The temperature range total time count settings are made by using the CXIntegrator.

Input Temperature Variation Detection

With Temperature Input Units, the temperature difference between two inputs for inputs 0 to 3 can be detected and compared with a monitoring set value. Explicit messages can be used to see if the temperature difference has exceeded the monitoring set value.

The input temperature variation detection settings are made by using the CXIntegrator.

Input Error Detection Disable Function

With Temperature Input Units, if there is an unused input, detection of input errors (including disconnection) can be disabled.

Input error detection is disabled by using the CX-Integrator.

Other Features

Rotary Switch Setting of Node Addresses

Node addresses can now be set much more easily using rotary switches.

Bit-level Distribution (Bit Slaves)

Slave Units are available with 2 inputs, 2 outputs, 4 inputs, or 2 inputs/2 outputs. These enable bit-level distribution of Slave Units. At the same time, unused Slave Unit I/O can be suppressed.

IP54 Dust-tight, Splashproof Units (Bit Slaves)

The CRT1B-@D@@SP(-1) Units conform to the IEC IP54 dust-tight, splashproof degree of protection (see note).

Note For protection against human bodies and solid foreign objects,

IP54 requires that dust will not penetrate inside the device to a degree that would affecting operation. For protection against water ingress, water splashing from any direction must have no adverse effect.

Page 29

Features of CompoNet Slave Units Section 1-1

Flat Cable Connected as a Standard Feature (Bit Slaves)

Bit Slave Units are sold with Standard or Sheathed Flat Cable already connected. Bit Slaves cannot be used, however, at a baud rate of 4 Mbps (no branch lines).

No I/O Power Supply Wiring Required (Bit Slaves)

External I/O (sensors or actuators) connected to Bit Slaves using e-CON connectors or clamp terminals are supplied power through the Flat Cable. No separate wiring is required for I/O power supply.

Industry Standard Sensor e-CON Connectors (CRT1-V@D08S(-1)/ CRT1-@D@@S(-1)/ CRT1-@D16SH(-1)/ CRT1B-@D02S(-1)/ CRT1B-@D0@SP(-1))

No special tools are required for connections because industry standard eCON connectors are used. Electrical cables do not need to be stripped and are simply inserted with pliers. When using e-CON connectors, there is no need to prepare special tools for wiring, and connectors from different makers can be used interchangeably.

Units with MIL Connectors (CRT1-V@D@@ML(-1))

MIL connectors, widely used in the electronic components and semiconductor industries, help reduce wiring requirements.

Units with Clamp Terminal Blocks (CRT1-@D@@SL(-

1)/CRT1B-MD04SLP(-1))

There is no need to tighten the screws because these Units use screw-less clamp terminal blocks. Connections are made simply by inserting the pin terminals. Wiring can be completed in one step.

1-2 Slave Unit Models

CompoNet Slave Units can be classified into the following groups.

Word Slave Units Word Slave Units are Slave Units that are allocated units of 16 bits (i.e.,

1 word) in I/O memory of the CPU Unit. Digital I/O Slave Units: Slave Units with digital I/O Analog I/O Slave Units: Slave Units with analog I/O Temperature Input Units: Slave Units with temperature inputs Expansion Units: Units that can be used to expand the number of I/O

points for Digital I/O Slave Units (with 2-tier terminal blocks and 16 points).

Bit Slave Units Bit Slave Units are Slave Units that are allocated units of 2 bits in I/O memory

of the CPU Unit. Bit Slave Units provide 2 or 4 digital contact I/O points and have Standard or Sheathed Flat Cable already connected.

Repeater Units Units that can be used to expand the network by extending trunk lines or

branching.

2-1 CompoNet Networks

2-1-1 Overall System Configuration and Elements

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

System Configuration Example

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 con-

nected to the trunk line.

CompoNet Networks Section 2-1

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.

• 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.

Page 55

CompoNet Networks Section 2-1

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.

2-1-2 Segments

Segment Layers When Repeater Units are used, the CompoNet Network is divided into seg-

ments by the Repeater Units. Each segment is connected to the network, but is isolated electrically. Three layers of these isolated segments can be configured, called segments 1, 2, and 3, counted in order from the Master Unit. Repeater Units can be used to add a maximum of two extra segment layers. Including Repeater Units connected using multidrop connections, a maximum of 64 Repeater Units can be connected in a single network (i.e., to a single Master Unit).

Number of Units Per Segment

A maximum of 32 Slave Units and Repeater Units can be connected in one segment.

2-2 Wiring Formations

There are two possible wiring formations for a CompoNet Network.

Trunk Line-Branch Line Formation

With this wiring formation, the trunk line is differentiated from branch lines and there are restrictions on the number of branches and the number of connections.

Unrestricted Wiring Formation

With this wiring formation, there is no distinction 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 in the number of branches.

The formation to be used is determined automatically by the type of cable to used and the required baud rate.

2-3-2 Criteria for Selecting Cables

Selecting Cable Types Select the cable type using the following items as conditions.

Note Bit Slaves come with a Flat Cable already connected. If this cable is removed,

the Unit cannot be connected.

Using Different Cable Types

The same type of cable must be used for all lines downstream from the Master Unit (i.e., the trunk line and branch lines, sub-trunk lines and their branch lines, and branch lines and sub-branch lines must use the same type of cable).

When Repeater Units are used, however, different cables can be used for the trunk line and sub-trunk lines, and for sub-trunk lines and sub-trunk lines, above and below a Repeater Unit.

Note Round cable I, round cable II, Flat Cable I (Standard) and Flat Cable II

(Sheathed) are treated as different types of cable.

Restrictions in Distance between Cables of Multiple CompoNet Systems

When using more than one CompoNet System with Flat Cable I or II, operation may be unstable due to interference. To prevent this, the Flat Cables for the different CompoNet Systems must be separated from each other by at least 5 mm.

Item Cable type

Round cable I Round cable II Flat Cable I Flat Cable II

Application • When using com-

mercially available cable is desirable.

• To provide communications power separately.

• When using commercially available cable is desirable.

• To supply communications power to all Slave Units with the communications cable.

• Applications in environments that required IP54 compliance (drip-proof, splash-proof).

Communications Cable Wiring Examples Section 2-4

2-4 Communications Cable Wiring Examples

The following wiring is required in a CompoNet Network.

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

• Two communications power supply lines (power for communications and internal Slave Unit circuits): BS+ (communications power supply plus side) and BS

− (communications power supply minus side)

The wiring method depends on the type of cable that is used.

2-4-1 Round Cable I

• Connect the two communications signal lines in parallel between the Master Unit or Repeater Unit and multiple Slave Units.

• Use Open Type Connectors (DCN4-TB4, for connecting Units) to connect Communications Cables to Master Units, Repeater Units, and Slave Units.

• To supply the communications power (24 VDC), connect the two communications power supply lines to each Slave Unit separately from the Communications Cables.

• Power is not supplied to the Master Unit or Repeater Units.

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

Slave Units can also be connected in parallel using multidrop connections.

Page 97

Power Supply Wiring Section 3-5

The method for supplying communications power and I/O power depends on the types of cable and Slave Unit that are used. The differences are shown in the following table.

Multi-power Supply Slave Units

Using Round Cable I • Communications Power Supply

Supply power to the power supply terminals of the communications connectors of individual Units (or to the PORT1 connector for Repeater Units).

• I/O Power Supply

Supply I/O power to the I/O power supply terminals of individual Units, separately from the communications power supply. To prevent noise, be sure to use separate power supplies for I/O and communications.

Using Round Cable II or Flat Cable I/II

• Communications Power Supply Supply communications power to the Master Unit's communications power

supply connector (or to the downstream port communications power supply connectors on Repeater Units).

• I/O Power Supply

Supply I/O power to the I/O power supply terminals of individual Units, separately from the communications power supply.

Power Supply Wiring Section 3-5

An OMRON S82-series Power Supply for the communications power supply for CompoNet Slave Units is recommended.

Note For network power supply Slave Units, the external I/O power supply is also

provided through the Flat Cable from the communications power supply connected to the Master Unit or the Repeater Unit. When calculating the output current of the communications power supply, always include the external I/O current consumption and actual load current for network power supply Slave Units. For example, the power supply current consumption for Bit Slave Unit is expressed by the following formula.

• Input Bit Slave Units: Communications power supply current consumption = Bit Slave Unit communications current consumption + (Bit Slave Unit input current

× number

of inputs used) + (sensor current consumption

× number of sensors used)

• Output Bit Slave Units: Communications power supply current consumption = Bit Slave Unit communications current consumption + (actual load current

× number of actu-

ators used)

• I/O Bit Slave Units: Communications power supply current consumption = Bit Slave Unit communications current consumption + (Bit Slave Unit input current

× number

of inputs used) + (sensor current consumption

× number of sensors used)

+ (actual load current

× number of actuators used)

For details on current consumption for each Unit, refer to Appendix D Current Consumption Summary.

Before connecting the power supply, first connect a DCN4-TB4 Open Type Connector to the communications connector to convert it to a screw terminal block.

When using a Repeater Unit, supply power through the BS+ and BS

− termi-

nals of the Repeater Unit's PORT1 connector.

Round Cable II or Flat Cable I/II

Connect a 24-VDC power supply to the Master Unit's communications power supply connector (BS+ and BS

−). This provides communications power to

each Slave Unit and Repeater Unit connected by round cable II or Flat Cable I/II. Connect only one communications power supply for the trunk line. The cable between the communications power supply and the communications power supply connector must be no longer than 3 m.

When Repeater Units are used, communications power to sub-trunk lines is supplied by the downstream port communications power supply connectors (BS+ and BS

−) of the Repeater Units. The cable between the communica-

tions power supply and the communications power supply connector must be no longer than 3 m.
