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.

• Force-setting/-resetting bits from a Programming Device.

• Transferring I/O memory files from a Memory Card or EM file memory to
the CPU Unit.

• Transferring I/O memory from a host computer or from another PLC on a
network.

Application Precautions 5

• Take appropriate measures to ensure that the specified power with the
rated voltage and frequency is supplied. Be particularly careful in places
where the power supply is unstable. An incorrect power supply may result
in malfunction.

• Install external breakers and take other safety measures against short-cir­cuiting in external wiring. Insufficient safety measures against short-cir­cuiting may result in burning.

• Fail-safe measures must be taken by the customer to ensure safety in the
event of incorrect, missing, or abnormal signals caused by broken signal
lines, momentary power interruptions, or other causes.

• Confirm voltage specifications when wiring communications, the power
supply, and I/O crossovers. Incorrect wiring may result in malfunction.

• Do not apply voltages or connect loads to the Output Units in excess of
the maximum switching capacity. Excess voltage or loads may result in
burning.

• Do not apply voltages to the Input Units in excess of the rated input volt­age. Excess voltages may result in burning.

• After replacing Units, resume operation only after transferring to the new
CPU Unit and/or Special I/O Units the contents of the DM Area, HR Area,
and other data required for resuming operation. Not doing so may result in
an unexpected operation.

• Check the user program for proper execution before actually running it on
the Unit. Not checking the program may result in unexpected operation.

• Check all wiring and switch settings to be sure they are correct.

• Always turn OFF the power supply to the PLC and Slave Units before
attempting any of the following. Not turning OFF the power supply may
result in malfunction or electric shock.

• Removing or attaching terminal blocks to Slave Units and Expansion
Units

• Removing or attaching the terminal blocks or connectors

• Replacing components (e.g., relays)

• Setting the DIP Switches and Rotary Switches

• Connecting cables or wiring the system.

• Confirm that no adverse effect will occur in the system before attempting
any of the following. Not doing so may result in an unexpected operation.

• Changing the operating mode of the PLC

• Force-setting/force-resetting any bit in memory

• Changing the present value of any word or any set value in memory
from the user program

• Touch a grounded piece of metal to discharge static electricity from your
body before touching any Unit.

• When replacing relays or other parts, be sure to confirm that the ratings of
the new part are correct. Not doing so may result in malfunction or burn­ing.

• Do not attempt to disassemble, repair, or modify any Units. Any attempt to
do so may result in malfunction, fire, or electric shock.

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

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

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

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.

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.

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.

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

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.

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.

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

Enables storing the error condition (communication failure details, the com­munications power supply voltage at the time of failure, and the Unit conduc­tion time) for the most recent 4 communication failures, within the slave unit.

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.

Power Short-circuit
Detection

Load Short-circuit
Detection

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.

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.

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.

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.

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.

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.

Node addresses can now be set much more easily using rotary switches.
(except some models)

Slave Units are available with 2 inputs, 2 outputs, 4 inputs, 4 outputs, 1 input/1
output, 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.

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.

Models of Bit Slave Units are available with a Flat Cable included (standard or
sheathed). Models with a Flat Cable included, however, do not support a baud
rate of 4 Mbps. (Branching is not possible.)

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

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.

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

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.

Slave Unit Models Section 1-2

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 : Bit Slave Units are Slave Units with 2 points or 4

points of digital I/O. They come with a Standard or
Sheathed Flat Cable included.

Bit Slaves with Compact Connectors:

Bit Slave Units with Compact Connectors are Slave
Units with 2 points or 4 points of digital I/O. They
have built-in compact connectors for the I/O inter­face that support connections with communications
cables using internal hook communications con­nectors.

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

branching.

CRS1-RPT01 • For trunk line-branch line formations, sub-trunk

lines can be connected under a Repeater Unit
just like they can be under the Master Unit.

• For unrestricted branching formations, there are
no restrictions on the connections.

• Repeater Units enable branching the trunk line,
adding more nodes, increasing the connection
distance, and changing the type of cable
upstream and downstream of the Repeater Unit.

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.

32

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.

33

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

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

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).

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.
Therefore, up to two extra segment layers can be created from the Master
Unit using Repeater Units. Accordingly, you can expand the length of one
trunk line and one branch line to up to 1,500 m (500 m × 3, 93.75 kbps).

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).

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.

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.

In a CompoNet Network, Units can be connected and cables can be branched
and extended by using Communications Cable and mounting connectors to
Units. The methods for connecting Communications Cables and Units and for
branching depend on the cable type and branching formation used.
