SECTION 1

Introduction

This section gives a brief overview of the history of Programmable Controllers and explains terms commonly used in ladderdiagram programming. It also provides an overview of the process of programming and operating a PC and explains basic terminology used with OMRON PCs. Descriptions of peripheral devices used with the C200HX/HG/HE PCs, a table of other manuals available to use with this manual for special PC applications, and a description of the new features of the C200HX/ HG/HE PCs are also provided.

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.

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.

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.

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 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, 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 Program, Section 7 Program Monitoring and Execution, and Section 9 Troubleshooting)

1-8-2 Program Compatibility

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 Cassette 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 capacity.

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.

SECTION 2

Hardware Considerations

This section provides information on hardware aspects of the C200HX/HG/HE that are relevant to programming and software operation. These include CPU Unit Components, the basic PC configuration, CPU Unit capabilities, and Memory Cassettes. This information is covered in detail in the C200HX/HG/HE Installation Guide.

2-1 CPU Unit Components

The following diagram shows the main CPU Unit components.

Communications Board (The C200HW-COM06-E is mounted to this CPU Unit.)

2-1-1 CPU Unit Indicators

CPU Unit indicators provide visual information on the general operation of the PC. Although not substitutes for proper error programming using the flags and other error indicators provided in the data areas of memory, these indicators provide ready confirmation of proper operation.

2-1-2 Peripheral Device Connection

Host Link Unit

Note The connector of the XW2Z-200S/500S Connecting Cable is a male 25-pin terminal. An adapter is required for the 9-pin male D-sub terminal on the IBM PC/AT or compatible side.

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.

2-4 Memory Cassettes

Note 1. Data stored in EEPROM won’t be reliable after the contents have been overwritten 50,000 times.

2.Use a standard PROM writer to write a program to the EPROM Memory Cassette. Connect an EPROM to the EPROM Memory Cassette before installing the EPROM Memory Cassette to the CPU Unit. The EPROM Memory Cassette will lose its data if it is removed from the CPU Unit.

2-4-1 Hardware and Software Settings

One-time Transfer using a Peripheral Device:

1, 2, 3… 1. Install the Memory Cassette containing the data into the C200HX/HG/HE.

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 SR 27001 (the Load UM from Cassette Bit). The data will be read from the Memory Cassette to the PC. SR 27001 will be turned OFF automatically after the data transfer has been completed.

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 Cassette

Note In C200HS PCs, the data transfer will be performed even if the memory capacities 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.

Reading IOM Data from a Memory Cassette

Note There is no function that automatically reads IOM data from the Memory Cassette.

1, 2, 3… 1. Install the Memory Cassette containing the data into the C200HX/HG/HE.

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 SR 27301 (the Load IOM from Cassette Bit). The data will be read from the Memory Cassette to the PC. SR 27301 will be turned OFF automatically after the data transfer has been completed.

CPU Unit DIP Switch Section 2-5

Note 1. The UM area contains the ladder program, fixed DM (including the PC Setup), expansion DM, I/O comments, the I/O table, and the UM area allocation information.

2. All six pins are set to OFF when the PC is shipped.

2-6 Operating without a Backup Battery

An EEPROM or EPROM Memory Cassette can be used together with various memory settings to enable operation without a backup battery. The following conditions must be met.

1, 2, 3… 1. The user program must be written to an EPROM or EEPROM Memory Cassette.

2.The clock cannot be used. (A battery is required to run the internal clock.)

3.The PC Setup must be set to not detect low battery voltage.

4.The system must be designed to run properly even if DM area data is lost.

5.The Output OFF Bit (SR 25215) must be programmed to remain OFF. (The status of this bit will be unstable without a battery.)

25314 (Always OFF Flag)

25215

6.The Forced Status Hold Bit (SR 25211) and Data Retention Control Bit (SR 25212) must be set to be cleared in the PC Setup. (The status of these bits will be unstable without a battery.)

7.The DIP switch on the CPU Unit must be set so that pin 1 is OFF and pin 2 is ON.

If these conditions can be met, use the following procedures to operate without a backup battery.

SECTION 3

Memory Areas

Various types of data are required to achieve effective and correct control. To facilitate managing this data, the PC is provided with various memory areas for data, each of which performs a different function. The areas generally accessible by the user for use in programming are classified as data areas. The other memory area is the UM Area, where the user’s program is actually stored. This section describes these areas individually and provides information that will be necessary to use them. As a matter of convention, the TR area is described in this section, even though it is not strictly a memory area.
