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.

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.

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.

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.

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.
