The Origins of PC Logic Section 1-2
1-1 Overview
A PC (Programmable Controller) is basically a CPU (Central Processing Unit)
containing a program and connected to input and output (I/O) devices. The program controls the PC so that when an input signal from an input device turns ON,
the appropriate response is made. The response normally involves turning ON
an output signal to some sort of output device. The input devices could be photoelectric sensors, pushbuttons on control panels, limit switches, or any other device that can produce a signal that can be input into the PC. The output devices
could be solenoids, switches activating indicator lamps, relays turning on motors, or any other devices that can be activated by signals output from the PC.
For example, a sensor detecting a passing product turns ON an input to the PC.
The PC responds by turning ON an output that activates a pusher that pushes
the product onto another conveyor for further processing. Another sensor, positioned higher than the first, turns ON a different input to indicate that the product
is too tall. The PC responds by turning on another pusher positioned before the
pusher mentioned above to push the too-tall product into a rejection box.
Although this example involves only two inputs and two outputs, it is typical of the
type of control operation that PCs can achieve. Actually even this example is
much more complex than it may at first appear because of the timing that would
be required, i.e., “How does the PC know when to activate each pusher?” Much
more complicated operations, however , are also possible. The problem is how
to get the desired control signals from available inputs at appropriate times.
To achieve proper control, the C200HX/HG/HE PCs use a form of PC logic
called ladder-diagram programming. This manual is written to explain ladderdiagram programming and to prepare the reader to program and operate the
PC.
1-2 The Origins of PC Logic
PCs historically originate in relay-based control systems. And although the integrated circuits and internal logic of the PC have taken the place of the discrete
relays, timers, counters, and other such devices, actual PC operation proceeds
as if those discrete devices were still in place. PC control, however, also provides computer capabilities and accuracy to achieve a great deal more flexibility
and reliability than is possible with relays.
The symbols and other control concepts used to describe PC operation also
come from relay-based control and form the basis of the ladder-diagram programming method. Most of the terms used to describe these symbols and concepts, however, have come in from computer terminology.
Relay vs. PC Terminology The terminology used throughout this manual is somewhat different from relay
terminology, but the concepts are the same.
The following table shows the relationship between relay terms and the PC
terms used for OMRON PCs.
Relay term PC equivalent
contact input or condition
coil output or work bit
NO relay normally open condition
NC relay normally closed condition
2
PC Terminology Section 1-3
Actually there is not a total equivalence between these terms. The term condition is only used to describe ladder diagram programs in general and is specifically equivalent to one of a certain set of basic instructions. The terms input and
output are not used in programming per se, except in reference to I/O bits that
are assigned to input and output signals coming into and leaving the PC. Normally open conditions and normally closed conditions are explained in 4-4 Basic
Ladder Diagrams.
1-3 PC Terminology
Although also provided in the Glossary at the back of this manual, the following
terms are crucial to understanding PC operation and are thus explained here.
PC Because the C200HX/HG/HE PCs are Rack PCs, there is no one product that is
a C200HX/HG/HE PC. That is why we talk about the configuration of the PC,
because a PC is a configuration of smaller Units.
To have a functional PC, you would need to have a CPU Rack with at least one
Unit mounted to it that provides I/O points. When we refer to the PC, however, we
are generally talking about the CPU Unit and all of the Units directly controlled by
it through the program. This does not include the I/O devices connected to PC
inputs and outputs.
If you are not familiar with the terms used above to describe a PC, refer to Sec-
tion 2 Hardware Considerations for explanations.
Inputs and Outputs A device connected to the PC that sends a signal to the PC is called an input
device; the signal it sends is called an input signal. A signal enters the PC
through terminals or through pins on a connector on a Unit. The place where a
signal enters the PC is called an input point. This input point is allocated a location in memory that reflects its status, i.e., either ON or OFF. This memory location is called an input bit. The CPU Unit, in its normal processing cycle, monitors
the status of all input points and turns ON or OFF corresponding input bits accordingly.
There are also output bits in memory that are allocated to output points on
Units through which output signals are sent to output devices, i.e., an output
bit is turned ON to send a signal to an output device through an output point. The
CPU Unit periodically turns output points ON or OFF according to the status of
the output bits.
These terms are used when describing different aspects of PC operation. When
programming, one is concerned with what information is held in memory , a nd s o
I/O bits are referred to. When talking about the Units that connect the PC to the
controlled system and the places on these Units where signals enter and leave
the PC, I/O points are referred to. When wiring these I/O points, the physical
counterparts of the I/O points, either terminals or connector pins, are referred to.
When talking about the signals that enter or leave the PC, one refers to input
signals and output signals, or sometimes just inputs and outputs. It all depends
on what aspect of PC operation is being talked about.
Controlled System and
Control System
The Control System includes the PC and all I/O devices it uses to control an external system. A sensor that provides information to achieve control is an input
device that is clearly part of the Control System. The controlled system is the
external system that is being controlled by the PC program through these I/O
devices. I/O devices can sometimes be considered part of the controlled system, e.g., a motor used to drive a conveyor belt.

Overview of PC Operation Section 1-5
1-4 OMRON Product Terminology
OMRON products are divided into several functional groups that have generic
names. Appendix A Standard Models list products according to these groups.
The term Unit is used to refer to all of the OMRON PC products. Although a Unit
is any one of the building blocks that goes together to form a C200HX/HG/HE
PC, its meaning is generally, but not always, limited in context to refer to the Units
that are mounted to a Rack. Most, but not all, of these products have names that
end with the word Unit.
The largest group of OMRON products is the I/O Units. These include all of the
Rack-mounting Units that provide non-dedicated input or output points for general use. I/O Units come with a variety of point connections and specifications.
High-density I/O Units are designed to provide high-density I/O capability a n d
include Group 2 High-density I/O Units and Special I/O High-density I/O Units.
Special I/O Units are dedicated Units that are designed to meet specific needs.
These include some of the High-density I/O Units, Position Control Units, Highspeed Counter Units, and Analog I/O Units.
Link Units are used to create Link Systems that link more than one PC or link a
single PC to remote I/O points. Link Units include Remote I/O Units, PC Link
Units, Host Link Units, SYSMAC NET Link Units, and SYSMAC LINK Units.
SYSMAC NET Link and SYSMAC LINK Units can be used with the CPU11-E
only.
Other product groups include Programming Devices, Peripheral Devices,
and DIN Rail Products.
1-5 Overview of PC Operation
The following are the basic steps involved in programming and operating a
C200HX/HG/HE PC. Assuming you have already purchased one or more of
these PCs, you must have a reasonable idea of the required information for
steps one and two, which are discussed briefly below. This manual is written to
explain steps three through six, eight, and nine. The relevant sections of this
manual that provide more information are listed with each of these steps.
1, 2, 3... 1. Determine what the controlled system must do, in what order, and at what
times.
2. Determine what Racks and what Units will be required. Refer to the
C200HX/HG/HE PC Installation Guide. If a Link System is required, refer to
the appropriate System Manual.
3. On paper , assign all input and output devices to I/O points on Units and determine which I/O bits will be allocated to each. If the PC includes Special I/O
Units or Link Systems, refer to the individual Operation Manuals or System
Manuals for details on I/O bit allocation. (Section 3 Memory Areas)
4. Using relay ladder symbols, write a program that represents the sequence
of required operations and their inter-relationships. Be sure to also program
appropriate responses for all possible emergency situations. (Section 4
Writing and Inputting the Program, Section 5 Instruction Set, Section 6 Program Execution Timing)
5. Input the program and all required operating parameters into the PC. (Section 4-7 Inputting, Modifying, and Checking the Program.)
6. Debug the program, first to eliminate any syntax errors, and then to find
execution errors. (Section 4-7 Inputting, Modifying, and Checking the Pro-
gram, Section 7 Program Monitoring and Execution, and Section 9 Troubleshooting)
4
Peripheral Devices Section 1-6
7. Wire the PC to the controlled system. This step can actually be started as
soon as step 3 has been completed. Refer to the C200HX/HG/HE PC Instal-
lation Guide and to Operation Manuals and System Manuals for details on
individual Units.
8. Test the program in an actual control situation and carry out fine tuning as
required. (Section 7 Program Monitoring and Execution and Section 9 Trou-
bleshooting)
9. Record two copies of the finished program on masters and store them safely
in different locations. (Section 4-7 Inputting, Modifying, and Checking the
Program)
Control System Design Designing the Control System is the first step in automating any process. A PC
can be programmed and operated only after the overall Control System is fully
understood. Designing the Control System requires, first of all, a thorough understanding of the system that is to be controlled. The first step in designing a
Control System is thus determining the requirements of the controlled system.
Input/Output Requirements The first thing that must be assessed is the number of input and output points
that the controlled system will require. This is done by identifying each device
that is to send an input signal to the PC or which is to receive an output signal
from the PC. Keep in mind that the number of I/O points available depends on
the configuration of the PC. Refer to 3-3 IR Area for details on I/O capacity and
the allocation of I/O bits to I/O points.
Sequence, Timing, and
Relationships
Unit Requirements The actual Units that will be mounted or connected to PC Racks must be deter-
Next, determine the sequence in which control operations are to occur and the
relative timing of the operations. Identify the physical relationships between the
I/O devices as well as the kinds of responses that should occur between them.
For instance, a photoelectric switch might be functionally tied to a motor by way
of a counter within the PC. When the PC receives an input from a start switch, it
could start the motor. The PC could then stop the motor when the counter has
received a specified number of input signals from the photoelectric switch.
Each of the related tasks must be similarly determined, from the beginning of the
control operation to the end.
mined according to the requirements of the I/O devices. Actual hardware specifications, such as voltage and current levels, as well as functional considerations,
such as those that require Special I/O Units or Link Systems will need to be considered. In many cases, Special I/O Units, Intelligent I/O Units, or Link Systems
can greatly reduce the programming burden. Details on these Units and Link
Systems are available in appropriate Operation Manuals and System Manuals.
Once the entire Control System has been designed, the task of programming,
debugging, and operation as described in the remaining sections of this manual
can begin.
1-6 Peripheral Devices

1-8-2 Program Compatibility
C200HS programs and Memory Cassettes can be used as is in the C200HX/
HG/HE and programs developed for the C200H can be transferred for use in the
C200HX/HG/HE very easily.
Detailed procedures for the individual steps involved in transferring programs
can be found in the SSS Operation Manuals. You will also require a
CQM1-CIF02 Connecting Cable to connect the computer running SSS to the
C200HS.
Precautions Observe the following precautions when transferring C200H programs to the
C200HX/HG/HE.
• If a C200H program including the SET SYSTEM instruction (SYS(49)) is transferred to the C200HX/HG/HE, the operating parameters set by this instruction
will be transferred to the C200HX/HG/HE’s PC Setup area (DM 6600, DM
6601, and DM 6655) and overwrite any current settings. Be sure to confirm
that the settings in these words are correct before using the PC after program
transfer.
8
C200HX/HG/HE Features Section 1-8
• If the C200H program accesses the C200H’s error log in DM 0969 to DM 0999,
the addresses of the words being accessed must be changed to DM 6000 to
DM 6030, which is the error log area for the C200HX/HG/HE.
• Any programs that rely on the execution cycle time (i.e., on the time required to
execute any one part of all of the program) must be adjusted when used on the
C200HX/HG/HE, which provides a much faster cycle time.
Using Internal Memory The following procedure outlines the steps to transfer C200H programs to the
user memory inside the C200HX/HG/HE.
1, 2, 3... 1. Transfer the program and any other required data to the SSS work area.
This data can be transferred from a C200H CPU Unit, from floppy disk, or
from a C200HS Memory Unit.
To transfer from a C200H CPU Unit, set the PC for the SSS to the C200H,
connect the SSS to the C200H, go online, and transfer the program and any
other required data to the SSS work area. You will probably want to transfer
DM data and the I/O table, if you have created an I/O table for the C200H.
or To transfer from floppy disk, set the PC for the SSS to the C200H in the
offline mode and load the program and any other require data to the SSS
work area. You will probably want to load DM data and the I/O table, if you
have created an I/O table for the C200H.
or To transfer from a C200H-MP831, set the PC for the SSS to the C200H in the
offline mode and read data from the Memory Unit into the SSS work area.
2. Go offline if the SSS is not already offline.
3. Change the PC setting for the SSS to the C200HX/HG/HE.
4. If you want to transfer I/O comments together with the program to the
C200HX/HG/HE, allocate UM area for I/O comments.
5. Connect the SSS to the C200HX/HG/HE and go online.
6. Make sure that pin 1 on the C200HX/HG/HE’s CPU Unit is OFF to enable
writing to the UM area.
7. Transfer the program and and any other required data to the C200HX/HG/
HE. You will probably want to transfer DM data and the I/O table, if you have
created an I/O table for the C200H.
8. Turn OFF the C200HX/HG/HE and then back ON to reset it.
9. Test program execution before attempting actual operation.
Using Memory Cassettes The following procedure outlines the steps to transfer C200H programs to the
C200HX/HG/HE via EEPROM or EPROM Memory Cassettes. This will allow
you to read the program data from the Memory Cassette automatically at
C200HX/HG/HE startup. The first four steps of this procedure is the same as
those used for transferring directly to the C200HX/HG/HE’s internal memory
(UM area).
1, 2, 3... 1. Transfer the program and any other required data to the SSS work area.
This data can be transferred from a C200H CPU Unit, from floppy disk, or
from a Memory Unit.
To transfer from a C200H CPU Unit, set the PC for the SSS to the C200H,
connect the SSS to the C200H, go online, and transfer the program and any
other required data to the SSS work area. You will probably want to transfer
DM data and the I/O table, if you have created an I/O table for the C200H.
or To transfer from floppy disk, set the PC for the SSS to the C200H in the
offline mode and load the program and any other required data to the SSS
work area. You will probably want to load DM data and the I/O table, if you
have created an I/O table for the C200H.
or To transfer from a C200H-MP831, set the PC for the SSS to the C200H in the
offline mode and read data from the Memory Unit into the SSS work area.

C200HX/HG/HE Features Section 1-8
2. Go offline if the SSS is not already offline.
3. Change the PC setting for the SSS to the C200HX/HG/HE.
4. If you want to transfer I/O comments together with the program to the
C200HX/HG/HE, allocate UM area for I/O comments.
5. Allocate expansion DM words DM 7000 to DM 7999 in the UM area using the
UM allocation operation from the SSS.
6. Copy DM 1000 through DM 1999 to DM 7000 through DM 7999.
7. Write “0100” to DM 6602 to automatically transfer the contents of DM 7000
through DM 7999 to DM 1000 through DM 1999 at startup.
8. To transfer to an EEPROM Memory Cassette, use the following procedure.
a) Connect the SSS to the C200HX/HG/HE and go online.
b) Make sure that pin 1 on the C200HX/HG/HE’s CPU Unit is OFF to enable
writing to the UM area.
c) Transfer the program and any other require data to the C200HX/HG/HE.
You will probably want to transfer DM data and the I/O table, if you have
created an I/O table for the C200H. Make sure you specify transfer of the
Expansion DM Area and, if desired, the I/O Comment Area.
d) Turn ON SR 27000 from the SSS to transfer UM data to the Memory Cas-
sette and continue from step 9.
or To transfer to an EPROM Memory Cassette, use the following procedure.
a) Connect a PROM Writer to the SSS and write the data to the EPROM
chip using the SSS EPROM writing operation.
b) Set the ROM type selector on the Memory Cassette to the correct capac-
ity.
c) Mount the ROM chip to the Memory Cassette.
d) Mount a EPROM Memory Cassette to the C200HX/HG/HE.
9. Turn ON pin 2 on the C200HX/HG/HE’s DIP switch to enable automatic
transfer of Memory Cassette data to the CPU Unit at startup.
10. Turn OFF the C200HX/HG/HE and then back ON to reset it and transfer
data from the Memory Cassette to the CPU Unit.
11. Test program execution before attempting actual operation.

CPU Unit Capabilities Section 2-3
2-2 PC Configuration
The basic PC configuration consists of two types of Rack: a CPU Rack and Expansion I/O Racks. The Expansion I/O Racks are not a required part of the basic
system. They are used to increase the number of I/O points. An illustration of
these Racks is provided in 3-3 IR Area. A third type of Rack, called a Slave Rack,
can be used when the PC is provided with a Remote I/O System.
CPU Racks A C200HX/HG/HE CPU Rack consists of three components: (1) The CPU Back-
plane, to which the CPU Unit and other Units are mounted. (2) The CPU Unit,
which executes the program and controls the PC. (3) Other Units, such as I/O
Units, Special I/O Units, and Link Units, which provide the physical I/O terminals
corresponding to I/O points.
A C200HX/HG/HE CPU Rack can be used alone or it can be connected to other
Racks to provide additional I/O points. The CPU Rack provides three, five, eight,
or ten slots to which these other Units can be mounted depending on the backplane used.
Expansion I/O Racks An Expansion I/O Rack can be thought of as an extension of the PC because it
provides additional slots to which other Units can be mounted. It is built onto an
Expansion I/O Backplane to which a Power Supply and up to ten other Units are
mounted.
An Expansion I/O Rack is always connected to the CPU Unit via the connectors
on the Backplanes, allowing communication between the two Racks. Up to three
Expansion I/O Racks (two with the C200HE PCs) can be connected in series to
the CPU Rack.
Unit Mounting Position Only I/O Units and Special I/O Units can be mounted to Slave Racks. All I/O
Units, Special I/O Units, Group-2 High-density I/O Units, Remote I/O Master
Units, PC and Host Link Units, can be mounted to any slot on all other Racks.
Interrupt Input Units must be mounted to Backplanes with the “-V2” suffix on the
model number.
Refer to t h e C200HX/HG/HE Installation Guide for details about which slots can
be used for which Units and other details about PC configuration. The way in
which I/O points on Units are allocated in memory is described in 3-3 IR Area.
2-3 CPU Unit Capabilities

Memory Cassettes Section 2-4
2-4 Memory Cassettes
The C200HX/HG/HE comes equipped with a built-in RAM for the user’s program, so a normal program be created even without installing a Memory Cassette. An optional Memory Cassette can be used to store the program, PC Setup, I/O comments, DM area and other data area contents. Refer to the C200HX/
HG/HE Installation Guide for details on installing Memory Cassettes.
Memory Cassette Functions The Memory Cassette can be used to store and retrieve UM and IOM data; UM
stored in the Memory Cassette can also be compared to the UM in the PC.
1, 2, 3... 1. The contents of UM (user memory) can be stored in the Memory Cassette
for later retrieval or verification. If pin 2 of the CPU Unit DIP switch is set to
ON, the contents of the Memory Cassette are automatically retrieved when
the PC is turned ON.
The UM area contains the ladder program, fixed DM (such as the PC Setup),
expansion DM, I/O comments, the I/O table, and th e UM ar ea allocation information.
2. The contents of the PC’s I/O memory (IOM) can be stored in the Memory
Cassette for later retrieval.
Compatible Memory
Cassettes
IOM includes the IR area, SR area, LR area, HR area, AR area, timer and
counter PVs, DM 0000 through DM 6143, and EM 0000 through EM 6143.
UM and IOM data is completely compatible between the C200HX/HG/HE and
the C200HS data, except the portion of the C200HX/HG/HE data areas that exceed the capacity of the C200HS and the new instructions (BXF2(––),
IEMS(––), IORD(––), IOWR(––), PMCR(––), STUP(––), and XFR2(––)) that
aren’t supported by the C200HS CPU Unit. Data area addresses and instructions that aren’t supported by the C200HS can’t be used in the C200HS. IOM
data can ’t be retrieved to the PC’s RAM unless the size of the IOM in the Memory
Cassette matches the size of the IOM in the PC.
There are two types of Memory Cassette available: EEPROM and EPROM. The
following table shows the Memory Cassettes which can be used with the
C200HX/HG/HE PCs.

5. If you want to write-protect the data on the Memory Cassette, turn OFF the
PC and set switch 1 of the Memory Cassette to ON. If this switch is ON, data
in the Memory Cassette will be retained even if SR 27000 is turned ON.
There are two ways to read UM data from a Memory Cassette: automatic transfer at startup or a one-time transfer using a Peripheral Device.
(There is no function that automatically writes data to the Memory Cassette.)
Automatic Transfer at Startup:
2. Install the Memory Cassette containing the data into the C200HX/HG/HE.
3. Turn ON the C200HX/HG/HE’s power supply. The contents of the Memory
Cassette will be transferred to the CPU Unit automatically . A memory error
will occur if the data couldn’t be transferred.
One-time Transfer using a Peripheral Device:
2. Turn ON the C200HX/HG/HE and switch it to PROGRAM mode.
3. Use a host computer running SSS or a Programming Console to turn ON

1, 2, 3... 1. Switch the C200HX/HG/HE to PROGRAM mode.
2. Use a host computer running SSS or a Programming Console to turn ON
SR 27002 (the Compare UM to Cassette Bit). The data will be compared between the PC and the Memory Cassette. SR 27002 will be turned OFF automatically after the data comparison has been completed.
3. Use a host computer running SSS or a Programming Console to check the
status of SR 27003 (the Comparison Results Flag).
Note If data verification is executed in a mode other than the PROGRAM mode, an
operation continuance error (FAL90) will occur and 27002 will turn ON (1). Although 27003 will also turn ON, comparison will not be performed. If data comparison is executed without mounting the Memory Cassette, 27003 will turn ON
(1).
2-4-3 Writing/Reading IOM Data
Use the following procedures to transfer IOM data to or from a Memory Cassette. (A PROM writer is required to write data to an EPROM Memory Cassette.
Refer to the SYSMAC Support Software Operation Manual for details.)
IOM includes the IR area, SR area, LR area, HR area, AR area, timer and counter PVs, DM 0000 through DM 6143, and EM 0000 through EM 6143.
The capacity of the Memory Cassette must match the memory capacity of the
CPU Unit when IOM data is transferred to or from a Memory Cassette. The
memory requirements are as follows:
Writing IOM: CPU Unit’s capacity ≤ Memory Cassette’s capacity
Reading IOM: CPU Unit’s capacity = Amount of IOM data in Memory Cas-
sette
Note In C200HS PCs, the data transfer will be performed even if the memory capaci-
ties don’t match, an error which can easily go unnoticed.
The following table shows the Memory Cassette capacity required to store 1 or
more banks of EM.

Bits 08 through 15 of SR 273 indicate the EM bank number of the IOM data
stored in the Memory Cassette.
Content of
SR 27308 to SR 27315
00 There is no Memory Cassette installed, no IOM data in
the Memory Cassette, or no EM data in the Memory Cassette.
01 The Memory Cassette contains IOM data that includes
EM bank 0 only.
04 The Memory Cassette contains IOM data that includes
EM banks 0 through 2.
Meaning
Use the following procedure to write IOM data to an EEPROM Memory Cassette.
1, 2, 3... 1. Before turning ON the C200HX/HG/HE’s power supply, make sure that
switch 1 on the Memory Cassette is set to OFF.
