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 pro- gram 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 photo- electric sensors, pushbuttons on control panels, limit switches, or any other de- vice 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 mo- tors, 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, posi- tioned 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 ladder- diagram 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 inte- grated 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 pro- vides 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 pro- gramming method. Most of the terms used to describe these symbols and con- cepts, 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
Actually there is not a total equivalence between these terms. The term condi- tion is only used to describe ladder diagram programs in general and is specifi- cally 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. Nor- mally 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 loca- tion in memory that reflects its status, i.e., either ON or OFF. This memory loca- tion 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 ac- cordingly.
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, and so 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.
The Control System includes the PC and all I/O devices it uses to control an ex- ternal 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 sys- tem, e.g., a motor used to drive a conveyor belt.
Controlled System and Control System
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 gen- eral 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 and 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, High- speed 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.
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 de- termine 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 Pro- gram Execution Timing)
5. Input the program and all required operating parameters into the PC. (Sec- tion 4-7 Inputting, Modifying, and Checking the Program.)
6. Debug the program, first to eliminate any syntax errors, and then to find ex- ecution errors. (Section 4-7 Inputting, Modifying, and Checking the Pro- gram, Section 7 Program Monitoring and Execution, and Section 9
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 Troubleshooting)
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 un- derstanding 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.
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.
Unit Requirements The actual Units that will be mounted or connected to PC Racks must be deter- mined according to the requirements of the I/O devices. Actual hardware specifi- cations, 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 con- sidered. 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 Programming Devices
The following Programming Devices can be used in programming, either to in- put/debug/monitor the PC program or to interface the PC to external devices to output the program or memory area data. Model numbers for all devices listed below are provided in Appendix A Standard Models. OMRON product names have been placed in bold when introduced in the following descriptions.
Programming Console A Programming Console is the simplest form of programming device for OM- RON PCs. All Programming Consoles are connected directly to the CPU Unit without requiring a separate interface.
The SYSMAC-CPT Support Software is the only support software currently compatible with the C200HX/HG/HE 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 modifi- Sequence, Timing, and

The following improvements have also been made for the ZE-version CPU Units.
• Function codes have been changed to three digits so that almost all of the in- structions can be used without allocating function codes.
• The SYSMAC-CPT Support Software can be used to greatly increase pro- gramming/monitoring functionality. (The previous Support Software cannot be used.)
• EM Area addresses can be directly address in instruction operands. This es- sentially doubles the word memory that can be accessed directly from the pro- gram (6,655 DM Area words plus 6,143 EM Area words).
• The maximum user memory capacity has been doubled from 32K words to 64K words.

1-8-3 Program Compatibility
Programs developed for the C200H, C200HS, and C200HX/HG/HE can be used in the C200HX/HG/HE(-ZE) PCs. Detailed procedures for the individual steps involved in transferring programs can be found in the SYSMAC Support Software Operation Manual and the SYSMAC-CPT Support Software Opera- tion Manual.
C200HX/HG/HE Precautions Observe the following precautions when transferring C200H programs to a C200HX/HG/HE PC.
• If a C200H program including the SET SYSTEM instruction (SYS(49)) is trans- ferred 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.
• 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.
Observe the following precautions using a C200HX/HG/HE-CPU-ZE CPU Unit.
• Comment lines in ZE-version programs created using the SYSMAC-CPT Sup- port Software are stored in CMT instructions (instructions that store line com- ment position information) in the CPU Unit. The size of C200HX/HG/HE pro- grams with line comments will thus increase if the programs are copied to a ZE-version C200HX/HG/HE CPU Unit using the SYSMAC-CPT Support Soft- ware. (The CMT instructions will be displayed on a Programming Console, but they cannot be added, changed, or deleted from a Programming Console.)
• The ZE-version C200HX/HG/HE CPU Units do not support the differentiated form of the TEN KEY instruction (@TKY), although it can be input from the SYSMAC-CPT. Do not use this instruction.
• Care must be taken when converting expansion instructions in C200HX/HG/
HE programs when importing, copying, or pasting them into ZE-version C200HX/HG/HE programs. If the default expansion instruction function codes are used, they will automatically be converted to 3-digit function codes. The instructions listed in the right column in the following table will not convert prop- erly and a message saying that there are no function codes for them will be displayed. Ether use the instructions listed in the right column or correct the program after conversion. (Even the instructions that don’t convert can be used by assigning function codes to them as expansion instructions.)

• The SYSMAC-CPT cannot be connected via a Host Link Unit.
• If the cycle time is longer than 100 ms when editing online from the SYSMAC- CPT, change the increment for the communications monitoring time (i.e., the timeout offset) to 10 s.
• It requires some time to write data to a Memory Casettes mounted to the CPU Unit. When using the SYSMAC-CPT to write data to a Memory Cassette from the user memory or I/O memory, change the increment for the communica- tions monitoring time (i.e., the timeout offset) to 15 s before turning ON the re- quired Control Bit in the SR Area.
ZE-version C200HX/HG/HE Precautions
To transfer from a C200H CPU Unit, set the PC to the C200H, connect the Support Software to the C200H, go online, and transfer the program and any other require data to the Support Software 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 a hard disk, set the Support Software to offline mode and load the program, DM data, and I/O table data to the Support Software work area. These will need to be loaded separately. You will probably want to load DM data and the I/O table, if you have created an I/O table for the C200H.
2. Go offline if the Support Software is not already offline.
3. Change the PC setting for the Support Software.
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 Support Software 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 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.
8. Turn the C200HX/HG/HE OFF 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 Support Software 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 Support Software to the C200H, connect the Support Software to the C200H, go online, and transfer the pro- gram and any other require data to the Support Software 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.

2. Go offline if the Support Software is not already offline.
3. Change the PC setting for the Support Software.
4. Change the PC setting for the Support Software to the C200HX/HG/HE.
5. If you want to transfer I/O comments together with the program to the C200HX/HG/HE, allocate UM area for I/O comments.
6. Allocate expansion DM words DM 7000 to DM 7999 in the UM area using the UM allocation operation from the Support Software.
7. Copy DM 1000 through DM 1999 to DM 7000 through DM 7999.
8. Write “0100” to DM 6602 to automatically transfer the contents of DM 7000 through DM 7999 to DM 1000 through DM 1999 at startup.
9. Use the following procedure to transfer to an EEPROM Memory Cassette.
a) Connect the Support Software 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 Support Software to transfer UM data to the Memory Cassette and continue from step 10.
10. 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.
11. Turn the C200HX/HG/HE OFF and then back ON to reset it and transfer data from the Memory Cassette to the CPU Unit.
12. Test program execution before attempting actual operation.

2-2 PC Configuration
The basic PC configuration consists of two types of Rack: a CPU Rack and Ex- pansion 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 back- plane 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 the 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.

2-4 Memory Cassettes
The C200HX/HG/HE comes equipped with a built-in RAM for the user’s pro- gram, so a normal program be created even without installing a Memory Cas- sette. An optional Memory Cassette can be used to store the program, PC Set- up, 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 the UM area allocation in- formation.
2. The contents of the PC’s I/O memory (IOM) can be stored in the Memory Cassette for later retrieval.
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 ZE-versions of the C200HX/HG/HE and other C200HX/HG/HE PCs, except the new instructions (symbol math and input comparison instructions) that aren’t supported by the original C200HX/HG/HE CPU Units.
There are two types of Memory Cassette available: EEPROM and EPROM. The following table summaries the Memory Cassettes which can be used with the C200HX/HG/HE PCs. Refer to Appendix A Standard Models for actual Memory Cassette model numbers and specifications.
Memory Capacity Comments
EEPROM 4K, 8K, 16K, 32K, or 64K words
The EEPROM Memory Cassette can be used to write and read UM and I/O data to the CPU Unit. It does not require any backup power supply and will retain its data even after it is removed from the CPU Unit.
EPROM 16K or 32K words
An EPROM Memory Cassette can be used only to back- up and read UM data.
Use a standard PROM writer to write the program to the EPROM Memory Cassette.
