shock.
xii
WARNING Provide safety measures in external circuits (i.e., not in the Programmable
!
Controller), including the following items, to ensure safety in the system if an
abnormality occurs due to malfunction of the PC or another external factor
affecting the PC operation. 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 PC 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 PC outputs may remain ON or OFF due to deposition 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 to the PC) is overloaded or
short-circuited, 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.
Caution Execute online edit only after confirming that no adverse effects will be caused
!
by extending the cycle time. Otherwise, the input signals may not be readable.
Caution Confirm safety at the destination node before transferring a program to another
!
node or changing contents of the I/O memory area. Doing either of these without
confirming safety may result in injury.

6Conformance to EC Directives
6 Conformance to EC Directives
Observe the following precautions when installing the C200HX/HG/HE PCs that
conform to the EC Directives.
1, 2, 3... 1. Since the C200HX/HG/HE PC is defined as an open type, be sure to install it
inside a panel.
2. Provide reinforced insulation or double insulation for the DC power source
connected to the DC I/O Unit and for a CPU Unit with a DC Power Supply
Unit.
3. The C200HX/HG/HE PC that conforms to the EC Directives also conforms,
as an individual unit, to the Common Emission Standard (EN50081-2) of the
EC Directives. When incorporated into a device, however, the C200HX/HG/
HE PC may not satisfy this Standard due to the noise produced by the contact output when it switches on and off. In such a case, it will be necessary to
take countermeasures such as connecting a surge or arc killer, or providing
an external means of protection for the PC. The countermeasures taken to
satisfy the Standard vary depending on the load devices, wiring, machinery
configuration, etc. Described on page 137 are examples of countermeasures to be taken to reduce the noise.
xv
Criteria for Taking Countermeasures
(Refer to EN50081-2 for details.)
Countermeasures are not required if the frequency of load switching for the
whole system with the PC included is less than 5 times per minute.
Countermeasures are not required if the frequency of load switching for the
whole system with the PC included is more than 5 times per minute.

What is a Control System? Section 1-1
1-1 What is a Control System?
A Control System is the electronic equipment needed to control a particular process. It may include everything from a process control computer, if one is used,
to the factory computer, down through the PCs (and there may be many of them
networked together) and then on down through the network to the control components: the switches, stepping motors, solenoids, and sensors which monitor
and control the mechanical operations.

A Control System can involve very large applications where many different models of PC are networked together or it could be an application as small as a single
PC controlling a single output device.

The Role of the PC Section 1-2
1-2 The Role of the PC
The Programmable Controller, or PC, is the part of the Control System that
directly controls the manufacturing process. According to the program stored in
its memory, the PC accepts data from the input devices connected to it, and uses
this data to monitor the controlled system. When the program calls for some
action to take place, the PC sends data to the output devices connected to it, to
cause that action to take place. The PC may be used to control a simple, repetitive task, or it may be connected to other PCs, or to a host computer in order to
integrate the control of a complex process.
1-2-1 Input Devices
PCs can receive input from either automated or manual devices. The PC could
receive data from the user via a pushbutton switch, keyboard, or similar device.
Automated input could come from a variety of devices: microswitches, timers,
encoders, photosensors, and so on. Some devices, like the Limit Switch shown
below, turn ON or OFF when the equipment actually makes contact with it. Other
devices, like the Photoelectric Switch and Proximity Switch shown below, use
other means, such as light or inductance, in order to get information about the
equipment being monitored.
1-2-2 Output Devices
Photoelectric switch Limit switch
Proximity switch
A PC can output to a myriad of devices for use in automated control. Almost anything that you can think of could be controlled (perhaps indirectly) by a PC. Some
of the most common devices are motors, Solenoids, Servomotors, Stepping
Motors, valves, switches, indicator lights, buzzers, and alarms. Some of these
output devices; such as the motors, Solenoids, Servomotors, Stepping Motors,
4

and valves; affect the controlled system directly. Others; such as the indicator
lights, buzzers, and alarms; provide output to notify personnel.
Solenoid
1-3 How Does a PC Work?
PCs operate by monitoring input signals and providing output signals. When
changes are detected in the signals, the PC reacts, through the user-programmed internal logic, to produce output signals. The PC continually scans the
program in its memory to achieve this control.

A program for your applications must be designed, and stored in the PC. This
program is then executed as part of the cycle of internal operations of the PC.
5
How Does a PC Work? Section 1-3
Cycle When a PC operates, that is, when it executes its program to control an external
system, a series of operations are performed inside the PC. These internal
operations can be broadly classified into the following four categories:
1, 2, 3... 1. Common (or overseeing) processes, such as watchdog timer operation and
testing the program memory.
2. Data input and output.
3. Instruction execution.
4. Peripheral device servicing.
Cycle Time The total time required for a PC to perform all these internal operations is called
the cycle time. The flowchart and diagram on the following page illustrate these
internal operations for a typical PC.
Timing is one of the most important factors in designing a Control System. For
accurate operations, it is necessary to have answers to such questions as these:
• How long does it take for the PC to execute all the instructions in its memory?
• How long does it take for the PC to produce a control output in response to a
given input signal?
The cycle time of the PC can be automatically calculated and monitored, but it is
necessary to have an understanding of the timing relationships within the PC for
effective system design and programming.

Peripheral Devices
2-3 Peripheral Devices
There are various Peripheral Devices that can be use to support C200HX/
C200HG/C200HE operation. These Peripheral Devices are introduced in this
section.
2-3-1 Programming Consoles
There are two Programming Consoles that can be used with the C200HX/
C200HG/C200HE: the C200H-PRO27-E and the CQM1-PRO01-E. The following illustration shows the C200H-PRO27-E Programming Console.

As shown in the illustration, the C200H-PRO27-E Programming Console connects to the C200HX/C200HG/C200HE CPU Unit with C200H-CN222 or
C200H-CN422 Connecting Cable, which must be purchased separately.
The CQM1-PRO01-E Programming Console comes with 2 m of Connecting
Cable.
2-3-2 Ladder Support Software (LSS)
The LSS is a powerful support software package for the OMRON C-series Programmable Controllers (PCs). The LSS runs on an IBM PC/AT or compatible
personal computer, and can be use to program, monitor and control PCs. While
some PCs require a SYSMAC NET Link Unit, Host Link Unit, or Peripheral Interface Unit to connect the computer running LSS, the C200HX/C200HG/C200HE
can be connected directly to the LSS via it’s peripheral or RS-232C port.
The LSS provides displays of various useful lists when the computer is operated
offline and can be used to monitor operating conditions of the PC, and to read
and write PC data. PC programs can be developed in a mnemonic or ladder diagram form.
The LSS supports the C200HX/C200HG/C200HE only within the functions
available for the C200HS.
C200H-PRO27-E Programming Console
31
Peripheral Devices
When working in ladder diagram form, not only the program is displayed but also
other information such as I/O, block, and instruction comments can be input and
displayed. Moreover, the LSS allows more than one PC to be connected to and
monitored using a single computer. The monitoring speed can be accelerated if
the optional S3200-NSB11-E SYSMAC NET NSB is used.
For details concerning LSS, refer to the Ladder Support Software Operation
Manual (W237).
2-3-3 SYSMAC Support Software (SSS)
The SSS is an advanced software application that runs on IBM PC/AT or compatibles and is used to program, monitor, and otherwise control OMRON SYSMAC
C-series PCs and SYSMAC CVM1 PCs. The C200HX/C200HG/C200HE can
be connected directly to a computer running the SSS in exactly the same way as
for the LSS.
The SSS can be used with any of the CVM1 PCs and with all of the many C-series PCs. The SSS automatically switches programming styles and other operations between the various PCs when a PC model is set in the SSS’s System
Setup.
All programs written on the Ladder Support Software or on the CV Support Software can be read and used by the SSS. Programs created for the C2000H or
C200HX/C200HG/C200HE families of PCs can be converted for use with CVM1
PCs so that existing programs can be used with the newer PCs.
The SSS naturally supports all of the functionality for C-series PCs as the LSS,
plus some new functions that facilitate fast, efficient programming and operation.
Section 2-3
2-3-4 SYSMAC-CPT Support Software
The SYSMAC-CPT Support Software is the only support software currently
compatible with the C200Hj-ZE PCs. This software is designed to run on IBM
PC/AT or compatibles and allows you to perform all the operations of the Programming Console as well as many additional ones. PC programs can be written on-screen in ladder-diagram form as well as in mnemonic form. As the program is written, it is displayed on a display, making confirmation and modification
quick and easy. Syntax checks may also be performed on the programs before
they are downloaded to the PC.
The SYSMAC-CPT Support Software does not support any of the original
C200HX/HG/HE CPU Units at present.

Installation Environment Section 3-1
3-1 Installation Environment
This section details the necessary environmental conditions for installing the
PC. Proper installation procedures and a proper environment are essential to
getting the best performance and reliability from your PC.
Caution Static electricity can damage PC components. Your body can carry an electros-
!
tatic charge, especially when the humidity is low. Before touching the PC, be
sure to first touch a grounded metallic object, such as a metal water pipe, in order
to discharge any static build-up.
3-1-1 Installation and Wiring Precautions.
Ambient Conditions Do not install the PC in any of the following locations. Doing so will affect PC life
and may adversely affect operating performance.
• Locations subject to direct sunlight.
• Locations subject to ambient temperatures lower than 0°C or higher than 55°C
(or higher than 45°C when using a Programming Console).
• Locations subject to ambient humidity lower than 35% or higher than 85%.
• Locations subject to condensation as the result of severe changes in tempera-
ture.
• Locations subject to corrosive or flammable gases.
• Locations subject to dust (especially iron dust) or salts.
• Locations subject to shock or vibration.
• Locations subject to exposure to water, oil, or chemicals.
• Take appropriate and sufficient countermeasures when installing systems in
the following locations.
• Locations subject to static electricity or other forms of noise.
• Locations subject to strong electromagnetic fields.
• Locations subject to possible exposure to radioactivity.
• Locations close to power supplies.
Cooling There are two points to consider in order to ensure that the PC does not over-
heat. The first is the clearance between the Racks, and the second is installation
of a cooling fan.
Clearance between Racks The Racks need to have sufficient room between each other to allow for I/O wir-
ing, and additional room to ensure that the I/O wiring does not hamper cooling.
The Racks must also be mounted so that the total length of the Connecting
Cable between all Racks in a given series does not exceed 12 m. As a general
rule, about 70 to 120 mm should be left between any two Racks. Consider factors such as the width of the wiring duct, wiring length, ventilation, and ease of
access to Units, when determining the spacing between Racks. Greater space
is required between Racks when using certain CPU Bus and Special I/O Units.
Refer to the operation manuals for the Units you are using for details.
50
Installation Environment Section 3-1
Cooling Fan A cooling fan is not always necessary, but may be needed in some installations.
Try to avoid mounting the PC in a warm area or over a source of heat. A cooling
fan is needed if the ambient temperature may become higher than that specified. If the PC is mounted in an enclosure, install a cooling fan, as shown in the
following diagram, to maintain the ambient temperature within specifications.
Fan
PC
Louver
Noise Resistance Abide by the following precautions to help increase resistance to noise.
• Do not mount the PC in a control panel containing high-voltage equipment.
• Install the PC at least 200 mm from power lines.
• Ground the mounting plate between the PC and the mounting surface.
3-1-2 Installing Racks
The following figures show two views, each consisting of a mounted CPU Rack
and two Expansion I/O Racks. Provide a space of 20 mm minimum on the upper
and lower sides of each duct for ventilation and Unit replacement.
Example Duct Layout

Each Rack must be mounted vertically, that is, with the printing on the front panels oriented as it would normally read. Racks may be mounted to any sturdy support meeting the environmental specifications.
Whenever possible, the Racks should be mounted to metal-plated mounting
plate that are securely grounded. If all of the Racks cannot be mounted to the
same mounting plate, the individual plates should be securely connected
2
together using 3 wires of at least 2 mm
in cross-sectional area. The Backplanes
are mounted to the plate(s) with four M4 screws each.
Whenever possible, use wiring conduit to hold the I/O wiring. Standard wiring
conduit should be used, and it should be long enough to completely contain the
I/O wiring and keep it separated from other cables.
51
Installation Environment Section 3-1
Note Tighten the PC Rack mounting screws, terminal block screws, and cable screws
to the torque of 1.2 N S m.
Caution Racks must be mounted horizontally so that the Units are upright (i.e., not upside
!
down or lying on their backs). The Units can overhead and malfunction if not
mounted properly.
I/O Connecting Cables Each I/O Connecting Cable can be up to 10 m long, but the sum total of all cables
between the CPU Rack and Expansion I/O Racks must be 12 m or less.
The duct work shown in the following diagram is recommended to hold I/O wiring. Although optional, this duct work can be used to house the wires from the I/O
Units that run along the sides of the Racks, keeping the wires from becoming
entangled. This figure illustrates the correct way to mount the Racks.

The CPU Unit of the C200HX/C200HG/C200HE has no I/O points built in. In
order to complete the PC it is necessary to mount at least one or more I/O Units
to the Backplane. Mount the I/O Unit to the Backplane by locking the top of the
I/O Unit into the slot on the Backplane and rotating the I/O Unit downwards as
shown in the following diagram.

3-1-7 I/O Connecting Cables
Each Rack must be mounted vertically, that is with the printing on the front panels oriented as it would normally be read. The Racks should be mounted one
above the other with the CPU Rack uppermost as shown below.
The C200HX/HG/HE is approved by Underwriters Laboratories under the condition that, “The device must be mounted vertically for ventilation purposes.”
Connect the CPU Rack to the first Expansion I/O Rack with an I/O Connecting
Cable and then connect each Expansion I/O Rack in order, again using I/O Connecting Cables. Each I/O Connecting Cable can be up to 10 m long, but the sum
total of all cables between the CPU Rack and Expansion I/O Racks must be 12 m
or less.
Firmly connect the I/O Connecting Cables to the connectors on the Backplanes
and tighten the connector screws. An I/O bus error will occur stopping PC operation if any of the I/O Connecting Cables is disconnected. Be sure to connect
these Cables carefully and securely.
This connector is
not used.
Cover is with a cap.
I/O Connecting
Cable
A hole of 53 mm is diameter is required to pass the connectors on the I/O Connecting Cables through. This hole can be reduced to 33 mm by removing the
hood from the connector, but be sure to reassemble the connector properly and
securely, and secure it with the connector screws.
The pull strength of the Cables is 5 kg. Do not allow more than 5 kg of force to be
applied to the Cables.
Note 1. The sum of the length of all I/O Connecting Cables in one PC must be 12 m
or less.
2. Be careful to connect the Cables in the correct locations.

sectional area of at least 2 mm
) to the GR terminal. The resistance to ground
must be 100 Ω or less. Do not use a wire longer than 20 m. Care must be taken,
because ground resistance is affected by environmental conditions such as soil
composition, water content, time of year, and the length of time since the wire
was laid underground.
The Line Ground (LG) terminal is a noise-filtered neutral terminal that does not
normally require grounding. If electrical noise is a problem, however, this terminal should be connected to the Ground (GR) terminal.
PC operation may be adversely affected if the ground wire is shared with other
equipment, or if the ground wire is attached to the metal structure of a building.

Power Interruptions
Section 3-2
This circuit prevents outputs MC1 and MC2 from ever both being ON at the same
time. Even if the PC is programmed improperly or malfunctions, the motor is protected.
A sequential circuit is built into the PC to handle power interruptions. This circuit
prevents malfunctions due to momentary power loss or voltage drops. A timing
diagram for the operation of this circuit is shown below.
The PC ignores all momentary power failures if the interruption lasts no longer
than 10 ms (no longer than 2 ms for a DC Power Supply). If the interruption lasts
between 10 and 25 ms (between 2 and 5 ms for a DC Power Supply), the interruption may or may not be detected. If the supply voltage drops below 85% of the
rated voltage for longer that 25 ms (less for the DC Power Supply), the PC will
stop operating and the external outputs will be automatically turned OFF.
Operation is resumed automatically when the voltage is restored to more than
85% of the rated value. The diagram below shows the timing of PC operation
and stopping during a power interruption. The time it takes to detect the power
failure is shorter when the power supply is DC. Also, the voltage value for which
the C200HX/HG/HE will stop due to a drop in the power supply voltage will be
lower than that for AC.
