Controller), including the following items, in order to ensure safety in the system if an abnormality occurs due to malfunction of the PC or another external
Safety Precautions3
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.
!WARNING Do not attempt to disassemble, repair, or modify any Units. Any attempt to do
so may result in malfunction, fire, or electric shock.
!WARNING Do not touch the Power Supply Unit while power is being supplied or immedi-
ately after power has been turned OFF. Doing so may result in burns.
!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.
!Caution Tighten the screws on the terminal block of the AC Power Supply Unit to the
torque specified in the operation manual. The loose screws may result in
burning or malfunction.

xviii
Application Precautions5
!Caution Failure to observe the following precautions could lead to faulty operation of
the PC or the system, or could damage the PC or PC Units. Always heed
these precautions.
• 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.
• Fail-safe measures must be taken by the customer to ensure safety in the
event that outputs from Output Units remain ON as a result of internal circuit failures, which can occur in relays, transistors, and other elements.
• Always turn ON power to the PC before turning ON power to the control
system. If the PC power supply is turned ON after the control power supply, temporary errors may result in control system signals because the
output terminals on DC Output Units and other Units will momentarily turn
ON when power is turned ON to the PC.
• Do not turn OFF the power supply to the PC when data is being transferred. In particular, do not turn OFF the power supply when reading or
writing a Memory Card. Also, do not remove the Memory Card when the
BUSY indicator is lit. To remove a Memory Card, first press the memory
card power supply switch and then wait for the BUSY indicator to go out
before removing the Memory Card.
• If the I/O Hold Bit (SR 25212) is turned ON, the outputs from the PC will
not be turned OFF and will maintain their previous status when the PC is
switched from RUN or MONITOR mode to PROGRAM mode. Make sure
that the external loads will not produce dangerous conditions when this
occurs. (When operation stops for a fatal error, including those produced
with the FALS(07) instruction, all outputs from Output Unit will be turned
OFF and only the internal output status will be maintained.)
• Install the Units properly as specified in the operation manuals. Improper
installation of the Units may result in malfunction.
• Mount Units only after checking terminal blocks and connectors completely.
• When assembling the Units or mounting the end cover, be sure to lock
them securely as shown in the following illustrations. If they are not properly locked, desired functionality may not be achieved.
• Be sure to mount the end cover to the rightmost Unit.
• Be sure that all the mounting screws, terminal screws, and cable connector screws are tightened to the torque specified in the relevant manuals.
Incorrect tightening torque may result in malfunction.
• Be sure that the terminal blocks, Memory Units, expansion I/O cables,
and other items with locking devices are properly locked into place.
Improper locking may result in malfunction.
• Be sure to confirm the orientation and polarities when connecting terminal
blocks and connectors.
• Leave the label attached to the Unit when wiring. Removing the label may
result in malfunction if foreign matter enters the Unit.
• Remove the label after the completion of wiring to ensure proper heat dissipation. Leaving the label attached may result in malfunction.
• Wire all connections correctly.
• When supplying power at 200 to 240 V AC from a CQM1-PA216 Power

• Always use the power supply voltages specified in the operation manuals.
An incorrect voltage may result in malfunction or burning.
• 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.
• Disconnect the functional ground terminal when performing withstand
voltage tests. Not disconnecting the functional ground terminal may result
in burning.
• Check switch settings, the contents of the DM Area, and other preparations before starting operation. Starting operation without the proper settings or data 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 an unexpected operation.
• Double-check all wiring and switch settings before turning ON the power
supply. Incorrect wiring may result in burning.
• 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 PC.
• Force-setting/force-resetting any bit in memory.
• Changing the present value of any word or any set value in memory.
• Before touching a Unit, be sure to first touch a grounded metallic object in
order to discharge any static build-up. Not doing so may result in malfunction or damage.
• Do not pull on the cables or bend the cables beyond their natural limit.
Doing either of these may break the cables.
• Do not place objects on top of the cables or other wiring lines. Doing so
may break the cables.
• Resume operation only after transferring to the new CPU Unit the contents of the DM Area, HR Area, and other data required for resuming
operation. Not doing so may result in an unexpected operation.
• Do not short the battery terminals or charge, disassemble, heat, or incinerate the battery. Do not subject the battery to strong shocks. Doing any
of these may result in leakage, rupture, heat generation, or ignition of the

to shock may leak if they are used.
• UL standards required that batteries be replaced only by experienced
technicians. Do not allow unqualified persons to replace batteries.
• When replacing parts, be sure to confirm that the rating of a new part is
correct. Not doing so may result in malfunction or burning.
• When transporting or storing circuit boards, cover them in antistatic material to protect them from static electricity and maintain the proper storage
temperature.
• Do not touch circuit boards or the components mounted to them with your
bare hands. There are sharp leads and other parts on the boards that
may cause injury if handled improperly.
• Before touching a Unit or Board, be sure to first touch a grounded metallic
object to discharge any static build-up from your body. Not doing so may
result in malfunction or damage.
• Provide sufficient clearances around the Unit and other devices to ensure
proper heat dissipation. Do not cover the ventilation openings of the Unit.
• For wiring, use crimp terminals of the appropriate size as specified in relevant manuals.
• Do not allow metallic objects or conductive wires to enter the Unit.
• Set the operating settings of the Temperature Controller properly according to the system to be controlled.
• Provide appropriate safety measures, such as overheat prevention and
alarm systems, in separate circuits to ensure safety of the entire system
even when the Temperature Controller malfunctions.
• Allow at least 10 minutes after turning ON the Temperature Controller as
warmup time.
• Do not use thinner to clean the product. Use commercially available
cleaning alcohol.
• Mount the I/O Control Unit on the right of the CPU Block.
• When using Expansion I/O Blocks, configure the system so that the current consumptions for the CPU Block and each of the Expansion I/O
Blocks do not exceed the specified values, and that the total current consumption does not exceed the current capacity of the Power Supply Unit.
• Configure the system so that the number of Units in both the CPU Block
and Expansion I/O Blocks do not exceed the maximum number of connectable Units for the Block.

Conformance to EC Directives6
6Conformance to EC Directives
6-1Applicable Directives
•EMC Directives
• Low Voltage Directive
6-2Concepts
EMC Directives
OMRON devices that comply with EC Directives also conform to the related
EMC standards so that they can be more easily built into other devices or
machines. The actual products have been checked for conformity to EMC
standards (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 in which the OMRON devices are installed.
The customer must, therefore, perform final checks to confirm that devices
and the overall machine conform to EMC standards.
Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:
Always ensure that devices operating at voltages of 50 to 1,000 V AC or 75 to
1,500 V DC meet the required safety standards for the PC (EN61131-2).
6-3Conformance to EC Directives
The CQM1H-series PCs comply with EC Directives. To ensure that the
machine or device in which a CQM1H-series PC is used complies with EC
directives, the PC must be installed as follows:
1, 2, 3...
1. The PC must be installed within a control panel.
2. Reinforced insulation or double insulation must be used for the DC power
supplies used for the communications and I/O power supplies.
3. PCs complying with EC Directives also conform to the Common Emission
Standard (EN61000-6-4). When a PC is built into a machine, however,
noise can be generated by switching devices using relay outputs and
cause the overall machine to fail to meet the Standards. If this occurs,
surge killers must be connected or other measures taken external to the
PC.
The following methods represent typical methods for reducing noise, and
may not be sufficient in all cases. Required countermeasures will vary depending on the devices connected to the control panel, wiring, the configuration of the system, and other conditions.
(Radiated emission: 10-m regulations)
6-4Relay Output Noise Reduction Methods
The CQM1H-series PCs conforms to the Common Emission Standards
(EN61000-6-4) of the EMC Directives. However, noise generated by relay out-
xxii
Conformance to EC Directives6
put switching may not satisfy these Standards. In such a case, a noise filter
must be connected to the load side or other appropriate countermeasures
must be provided external to the PC.
Countermeasures taken to satisfy the standards vary depending on the
devices on the load side, wiring, configuration of machines, etc. Following are
examples of countermeasures for reducing the generated noise.
Countermeasures
Refer to EN61000-6-4 for more details.
Countermeasures are not required if the frequency of load switching for the
whole system including the PC is less than 5 times per minute.
Countermeasures are required if the frequency of load switching for the whole
system including the PC is 5 times or more per minute.
Countermeasure Examples
When switching an inductive load, connect a surge protector, diodes, etc., in
parallel with the load or contact as shown below.

the load changes energy accumulated
by the coil into a current, which then
flows into the coil so that the current will

longer than that caused by the CR
method.
imposition of high voltage between the
contacts by using the constant voltage
characteristic of the varistor. There is
time lag between the moment the
circuit is opened and the moment the
load is reset.
If the supply voltage is 24 or 48 V, insert
the varistor in parallel with the load. If
the supply voltage is 100 to 200 V,
insert the varistor between the
contacts.
The capacitance of the capacitor must
be 1 to 0.5 µF per contact current of
1 A and resistance of the resistor must
be 0.5 to 1 Ω per contact voltage of 1 V.
These values, however, vary with the
load and the characteristics of the
relay. Decide these values from testing,
and take into consideration that the
capacitance suppresses spark
discharge when the contacts are
separated and the resistance limits the
current that flows into the load when
the circuit is closed again.
The dielectric strength of the capacitor
must be 200 to 300 V. If the circuit is an
AC circuit, use a capacitor with no
polarity.
The reversed dielectric strength value
of the diode must be at least 10 times
as large as the circuit voltage value.
The forward current of the diode must
be the same as or larger than the load
current.
The reversed dielectric strength value
of the diode may be two to three times
larger than the supply voltage if the
surge protector is applied to electronic
circuits with low circuit voltages.

SECTION 1
Introduction
This section describes the CQM1H’s special features and functions, describes the system configurations, and outlines the
steps required before operation. It also provides a list of CQM1H functions by purpose and a comparison between the
CQM1H and the CQM1. Read this section first if you have not previously used the CQM1H.
Refer to the CQM1H Programming Manual for information on programming.
The CQM1H is a compact Programmable Controller (PC) that supports communications and other advanced functions. It is a package-type PC that is
mounted to DIN Track to control small to medium-size machines.
A flexible system configuration is enhanced by serial communications with a
protocol macro function, user-installed boards called Inner Boards, network
communications, a wide range of monitoring and setting methods, higher
speed, and larger capacity. These features enable added-value machine control.
• Mount up to two Inner Boards to add communications or control functions.
Communications Functions: Serial Communications Board
Control Functions: High-speed Counter Board, Pulse I/O Board, Absolute
Encoder Interface Board, Analog Setting Board, and Analog I/O Board
• Mount a Controller Link Unit to connect to a Controller Link Network.
• Connect simultaneously to both a Programming Device and a Programmable Terminal (PT).
• Obtain higher speed and capacity in comparison to the CQM1: 1.25 times
faster, twice the program capacity (15.2 Kwords), twice the I/O capacity
(512 points), and twice the data memory capacity (12 Kwords).
• Use new instructions.
• Maintain compatibility with previous models of PC.
Flexible System
Configuration
Higher Speeds and
Greater Capacity
The CQM1H does not require a Backplane and is constructed by connecting
Units via connectors on the sides of the Units, allowing flexible system configuration. The CPU Unit contains 16 built-in DC input points. Two Inner Boards
can be mounted in the CPU Unit. One Controller Link Unit (a Communications
Unit) and a combined maximum of eleven I/O Units and Dedicated I/O Units
can also be connected. If an Expansion I/O Block is used, a maximum of 16
Units can be connected. (See 1-2-1 Basic Configuration.)
Note1. The CQM1H is mounted to DIN Track.
2. Only the CQM1H-CPU51/61 CPU Units support Inner Boards and the
Controller Link Unit.

cycle time by approximately 25%.
• The program capacity, the I/O capacity, and the data memory capacity
have all been approximately doubled. The program capacity has been
increased to 15.2 Kwords (from 7.2 Kwords for the CQM1); the I/O capac-

ity, to 512 points (from 256 points); and the data memory capacity, to
6 Kwords of DM and 6 Kwords of EM (from 6 Kwords of DM only).
• A 16-Kword Memory Cassette can be mounted in the CQM1H to handle
large user programs or more data. These features ensure a higher level
of machine control and greater ease of use.
Increased Functionality
with Inner Boards
The CQM1H features Inner Boards that allow serial communications, multipoint high-speed counter (rotary encoder) inputs, simple positioning (trapezoidal acceleration/deceleration pulse outputs), speed changes, PWM (variable
duty-factor pulse) outputs, absolute rotary encoder inputs, analog I/O (4
inputs, 2 outputs), and analog settings.
A Serial Communications Board, High-speed Counter Board, Pulse I/O
Board, Absolute Encoder Interface Board, Analog I/O Board, and Analog Setting Board are available. These Inner Boards can be combined, mounted and
used as required for the machine being controlled. (There are mounting
restrictions for some of the Inner Boards.)
Note The CPU Unit also provides16 built-in inputs, as well as high-speed counter
and input interrupt functions. Pulse outputs are also supported using a standard Transistor Output Unit.

Better Connections to
Machine Components with
Serial Communications
Connections can be easily made to general-purpose machine components
and dedicated controllers. The Serial Communications Board (an Inner
Board) supports a protocol macro function. You can create macros for protocols according to the communications specifications of the external device,
allowing data transfers with general-purpose devices to be executed with a
single PMCR instruction. Essentially any device with a serial port can be communicated with, such as temperature controllers, bar-code readers, and dedicated numeric controllers.

A Controller Link Unit can be included in the CQM1H. Data can be exchanged
between several PCs using a Controller Link Network. Data links are supported to create shared data areas and message communications are supported to enable sending required data and commands using network
communications instructions. The Controller Link Network can be easily constructed using twisted-pair cable. Data exchange is also supported with
C200HX/HG/HE, CS-series, CVM1, and CV-series PCs, as well as with personal computers.
Note Data links can be created with another CQM1H or with a CQM1, CPM1,
CPM1A, CPM2A, CPM2C, SRM1, C200HX/HG/HE, or C200HS simply by
making a 1:1 connection between the built-in RS-232C ports in the CPU
Units.

from a PT while monitoring or programming from a Programming Console or a
personal computer.

You can also program and monitor from a personal computer at a remote
location via a modem. When used in combination with the protocol macro
function, it is also possible to call the personal computer from the CQM1H
using the PMCR(––) instruction, and when the connection is made, switch the
serial communications mode to Host Link (for remote programming/monitoring) using the STUP(––) instruction.
If an Analog Setting Board is mounted, fine adjustments of settings, such as
rotational speed or timer settings, are possible on-site using the adjustments
on the front of the Board.
The ON/OFF status of a user-programmable DIP switch pin is stored in the
AR area. The setting of this pin can be used on-site to switch between trial
operation and actual operation, to switch set values, or to perform any other
function that can be programmed in response to the changes in status of the
AR bit corresponding to this DIP switch pin.

Included
Math instructions (such as floating-point math, exponential functions, logarithmic functions, and trigonometric functions), a TOTALIZING TIMER
(TTIM(––)) instruction, a CHANGE RS-232C SETUP (STUP(––)) instruction,
and network communications instructions have been added. In addition, complete interrupt functions for the CPU Unit are supported, including input interrupts, high-speed counter interrupts, and interval timer interrupts (with
scheduled interrupts and one-shot interrupts). Interrupts from serial communications using a protocol macro (interrupt notification) are also supported.
These interrupts enable easier and more flexible machine control.
A Memory Cassette (EEPROM or flash memory) can be mounted in the front
of the CPU Unit. User programs, data memory (read-only DM, PC Setup) and
expansion instruction information can be saved and read in batch. It is also
possible to make settings so that data contained in the Memory Cassette is
loaded automatically at startup. This feature means that, in the event of battery expiration or careless programming/monitoring operations, data for user
programs and data memory is not lost. It also means that changes in user
programs required for different controlled machines can be made easily. Further, by using a Memory Cassette with a clock, times and dates can be used
in the user program.

The Power Supply Units, Basic I/O Units, and Dedicated I/O Units for the
CQM1 can be used in the CQM1H. Consequently, Dedicated I/O Units like
Temperature Control Units, Sensor Units, B7A Interface Units, and CompoBus/D (DeviceNet) Link Units can all be used. In addition, user programs used
on the CQM1, Programming Consoles for the CQM1 and conventional Memory Cassettes can also be used. (A conversion adapter is necessary to use
the Programming Console.)

When only a CPU Block is used, a maximum of 11 I/O Units and Dedicated I/
O Units can be connected to the CQM1H-series CPU Unit. When an Expansion I/O Block is also used, a maximum of 5 I/O Units and Dedicated I/O Units
can be connected to the CQM1H-series CPU Unit and a maximum of 11 I/O
Units and Dedicated I/O Units can be connected to the Expansion I/O Block. If
these limits are exceeded, the CQM1H may not operate properly because of
drops in the voltage of the 5-V internal power supply. The CQM1H will detect if
the maximum number of I/O points has been exceeded (as explained below),
but will not detect if the maximum number of Units has been exceeded. Therefore, design the system so that the maximum number of Units is not
exceeded.
Exceeding Maximum
Number of I/O Points
When the maximum number of I/O points is exceeded, an “I/O UNIT OVER”
message will be displayed and operation will stop. For details on I/O UNIT
OVER errors, refer to the CQM1H Programming Manual.
The relationship between the maximum number of I/O points and Unit word
allocation is shown in the following table. The CPU Unit has 16 built-in inputs
for which one word is allocated.

Expanded System ConfigurationSection 1-3
Refer to the CQM1H Programming Manual for the number of words allocated
to each Unit and other information on memory allocation to Units.
Note1. It is possible to exceed the maximum number of Units without exceeding
the maximum number of I/O points (and words allocated). For example,
with the CQM1H-CPU61, if 12 Units that are allocated 1 word each are
connected, the total number of words allocated will be 13 (including the 1
word allocated for the CPU Unit built-in inputs), which is less than the specified maximum. The number of Units, however, exceeds the maximum of
11.
2. It is also possible to exceed the maximum number of I/O points (and words
allocated) without exceeding the maximum number of Units. For example,
with the CQM1H-CPU61, if 8 Units that are allocated 4 words each are
connected, the maximum number of Units is not exceeded. However, the
total word allocation will be (4
× 8) + 1 = 33 words (including the 1 word
allocated for the CPU Unit built-in inputs), and so consequently the maximum number of 32 words is exceeded.

The Host Link System allows the I/O memory of the PC to be read/written,
and the operating mode to be changed from a host computer (personal computer or Programmable Terminal) by executing Host Link commands. Other
Programming Devices can also be connected via a computer using this mode.
Alternatively, it is also possible to send data from the CPU Unit of the CQM1H
to the host computer using TXD(––) instructions to initiate communications
from the PC. This mode is supported by the peripheral port and the RS-232C

CQM1H
No-protocol
Communications
The TXD(––) and RXD(––) instructions in the ladder program can be used
with no communications protocol or conversion to transfer data with a generalpurpose external device equipped with an RS-232C port. It is possible to
attach a start code to the beginning and an end code to the end of data (or
specify the amount of data) when sending/receiving. Unlike protocol macro, it
is not possible to construct a communications frame (message) according to
the communications specifications of the communications partner. Also, there
are no procedures for retry processing, data format conversion processing or
branch processing for receiving data. This communications mode is thus used
for simple data transmissions, such as inputting bar code data and outputting
printer data. This mode is supported by the peripheral port and the RS-232C
port on the CPU Unit, as well as the RS-232C port and RS-422A/485 port on
the Serial Communications Board.

1:1 Data Link SystemIf two PCs are linked one-to-one by connecting them together through their
RS-232C ports, they can share up to 64 words of LR area. One of the PCs will

NT Link SystemIf a PC and Programmable Terminal (PT) are connected together using RS-
232C or RS-422A/485, the allocations for the PT’s status control area, status
notify area, and objects (such as touch switches, indicators, and memory
maps) can be allocated in the I/O memory of the PC. The NT Link System
allows the PT to be controlled by the PC, and the PT can periodically read
data from the status control area of the PC to perform necessary operations if
there are any changes in the area. The PT can communicate with the PC by
writing data to the status notify area or the I/O memory of the PC from the PT.
The NT Link system allows the PT status to be controlled and monitored without using the PC’s ladder program.
There are two NT Link modes: One is for communications between one PC
and one PT (1:1 mode), and the other is for communications between one PC,
and one or many PTs (1:N mode). These modes support completely different
communications.

Protocol MacrosThe CX-Protocol is used to create sets of data transmission procedures called
protocols for general-purpose external devices according to the communications specifications of the general-purpose external devices. Communications
must be half-duplex and must use start-stop synchronization. The protocols
that have been created are recorded in a Serial Communications Board,
enabling data to be sent to and received from the external devices by simply
executing the PMCR(––) instruction in the CPU Unit. Protocols for data communications with OMRON devices, such as Temperature Controllers, Intelligent Signal Processors, Bar Code Readers, and Modems, are supported as
standard protocols (see note 1). These protocols can be changed to suit user
needs. Protocol macros are supported by the RS-232C port and RS-422A/
485 port on the Serial Communications Board (see note 2).
25
Expanded System ConfigurationSection 1-3
Note1. The standard protocols are provided as standard features with the CX-Pro-
tocol and Serial Communications Boards.

Note CompoWay/F (Host Function)
A CQM1H CPU Unit can operate as a host to send CompoWay/F commands
to OMRON components connected in the system. CompoWay/F commands
are executed by using the CompoWay/F send/receive sequences in one of the
standard protocols provided in the protocol macros.
1-3-2Communications Networks
With the CQM1H CPU Unit, networks can be created using the following
Communications Units:
• CompoBus/S Master Unit
• Controller Link Unit (CQM1H-CPU51/61 only)
CompoBus/S NetworkCompoBus/S is a high-speed ON/OFF bus for remote I/O communications.
Connecting a CQM1-SRM21-V1 CompoBus/S Master Unit (a Dedicated I/O
Unit) to the network allows remote I/O communications, without programming
in the CPU Unit, between the PC and Slaves. High-speed communications
are performed with 256 points in a cycle time of 1 ms max. With the CQM1HSRM21-V1, a long-distance communications mode is also available in addition to the previous high-speed communications mode, enabling communications on a trunk line of up to 500 m.

Controller Link NetworkThe Controller Link Network is the basic network of the OMRON PC FA Net-
works. When using a CQM1H-CPU51/61 CPU Unit, the CQM1H can be connected to the network using a Controller Link Unit. This enables the flexible
and simple transfer of large amounts of data with other OMRON PCs (e.g.,
CQM1H, CS-series, C200HX/HG/HE, CVM1, and CV-series PCs) or with personal computers. Data links can be created between PCs so that data can be
shared without programming and FINS message communications can be per-

system with effective use of data areas.

Mounted from the front of the CPU Unit. Memory Cassettes are used to store and read the
user’s program, DM (read-only data and PC Setup), and expansion instruction information (as
one block of data).
It is possible to set the CPU Unit so that when power is turned ON, data stored in the Memory
Cassette (user’s program, DM, expansion instruction information) is automatically transferred,
in one block, to the CPU Unit (auto-boot). Two-way transfer, and comparison of data between
the CPU Unit and Memory Cassette is possible using AR area settings.

1-6Overview Application Procedure
The following procedure outlines the steps necessary to set up, program, and
operate a CQM1H control system.
1,2,3...1. Determine the system configuration.
Decide if one or more Inner Boards are required in the system and whether
they are to be mounted in the left or right slot. The following boards are
available.
• Serial Communications Board for serial communications.
• High-speed Counter Board or Pulse I/O Board for high-speed counter
inputs.
• Pulse I/O Board or pulse outputs.
• Absolute Encoder Interface Board for inputs from an absolute encoder.
• Analog Setting Board to input settings via variable resistors.
• Analog I/O Board for analog I/O.
Also, decide if it will be necessary to connect to a Controller Link System.
2. Allocate I/O.
Nothing is required to allocate I/O with the CQM1H. I/O tables are not required and all I/O is allocated automatically. Words are allocated to I/O
Units starting at the CPU Unit and going to the right, with Input Units being
allocated words starting at IR 001 and Output Units being allocated words
starting at IR 100.
3. Set settings in the PC Setup.
The PC Setup can be used to control the functions of the CPU Unit and
Inner Boards. The default settings in the PC Setup must be confirmed and
if any changes are required, they must be made from a Programming Device before starting operation. The PC Setup must be changed to use Inner
Boards.
41
Overview Application ProcedureSection 1-6
4. Assemble the PC.
5. Turn ON the power supply.
6. Write the ladder program.
7. Transfer the program to the CPU Unit.
8. Test operation.
The following steps must be performed in trial operation.
a) Check I/O wiring.
b) Set the required bits in memory (such as the I/O Hold Bit).
c) Monitor operation and debug the system in MONITOR Mode.
9. Correct the program and return to step 7., above.
10. Store/print the program.
11. Begin actual operation.

Input Interrupt Mode: Interrupt is executed in response to input from an external
source to the CPU Unit’s built-in input points.
Counter Mode: Interrupt is executed in response to input received a certain
number of times (counted down) via the CPU Unit’s internal built-in input points
(4 points).
Scheduled Interrupt Mode: Program is interrupted at regular intervals measured by
one the CPU Unit’s internal timers.
One-shot Interrupt Mode: One interrupt is executed after a certain time, measured
by one of the CPU Unit’s internal timers.
Target Value Comparison: Interrupt is executed when the high-speed counter PV
is equal to a specified value.
Range Comparison: Interrupt is executed when the high-speed counter PV lies
within a specified range.
Note Counting is possible for high-speed counter inputs from the CPU Unit’s inter-
nal input points, Pulse I/O Boards, or Absolute Encoder
Interface Boards. (The High-speed Counter Board has no interrupt function,
and can only output bit patterns internally and externally.)
(Because there are no I/O tables, it is not necessary, and not possible, to create
I/O tables from a Programming Device.)
