• Changing the present value of any word or any set value in memory.

• 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 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.

• Use crimp terminals for wiring. Do not connect bare stranded wires directly to
terminals. Connection of bare stranded wires may result in burning.

• 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.

• Before touching a Unit, be sure to first touch a grounded metallic object in order
to discharge any static built-up. Not doing so may result in malfunction or dam­age.

Introduction

This section provides general information about Programmable Controllers
(Systems) and how they fit into a Control System.

1-1 What is a Control System?

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

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

In the typical Control System example shown above, a PC controls the move­ment of the workpiece bed across two horizontal axes using Limit Switches
and Servomotors to monitor and control movement.

1-2 The Role of the PC

The PC is the part of the Control System that directly controls the manufac­turing process. According to the program stored in its memory, the PC ac­cepts data from the input devices connected to it, and uses this data to moni­tor the controlled system. When the program calls for some action to take
place, the PC sends data to the output devices connected to it to cause that
action to take place. The PC may be used to control a simple, repetitive task,
or it may be connected to other PCs, or to a host computer in order to inte­grate the control of a complex process.

3

1-2-1 Input Devices

PCs can receive input from either automated or manual devices. The PC
could receive data from the user via a pushbutton switch, keyboard, or simi­lar device. Automated input could come from a variety of devices: micro­switches, timers, encoders, photosensors, and so on. Some devices, like the
Limit Switch shown below, turn ON or OFF when the equipment actually
makes contact with them. Other devices, like the Photoelectric Switch and
Proximity Switch shown below, use other means, such as light or inductance,
in order to get information about the equipment being monitored.

Section 1Introduction

Photoelectric Switch

1-2-2 Output Devices

A PC can output to a myriad of devices for use in automated control. Almost
anything that you can think of could be controlled (perhaps indirectly) by a
PC. Some of the most common devices are motors, Solenoids, Servomotors,
Stepping Motors, valves, switches, indicator lights, buzzers, and alarms.
Some of these output devices, such as the motors, Solenoids, Servomotors,
Stepping Motors, and valves, affect the controlled system directly. Others,
such as the indicator lights, buzzers, and alarms, provide output to notify per­sonnel.

1-3 How Does a PC Work?

PCs operate by monitoring input signals and providing output signals. When
changes are detected in the signals, the PC reacts, through the user-pro­grammed internal logic, to produce output signals. The PC continually cycles
the program in its memory to achieve this control.

A program for your applications must be designed, and stored in the PC. This
program is then executed as part of the cycle of internal operations of the
PC.

When a PC operates, that is, when it executes its program to control an ex­ternal system, a series of operations are performed inside the PC. These in­ternal operations can be broadly classified into the following four categories:

1. Common (or overseeing) processes, such as watchdog timer operation

and testing the program memory.

2. Data input and output.

Cycle Time

3. Instruction execution.

4. Peripheral device servicing.

The total time required for a PC to perform all these internal operations is
called the cycle time. The flowchart and diagram on page 7 illustrate these
internal operations for a typical PC.

Timing is one of the most important factors in designing a Control System.
For accurate operations, it is necessary to have answers to such questions
as these:

• How long does it take for the PC to execute all the instructions in its mem­ory?

5

Section 1Introduction

• How long does it take for the PC to produce a control output in response to
a given input signal?

The cycle time of the PC can be automatically calculated and monitored, but
it is necessary to have an understanding of the timing relationships within the
PC for effective System design and programming.

The CPU is equipped with one connector for peripheral devices. A peripheral
device, such as the CPU-Mounting Programming Console, can be mounted
directly to the CPU and does not require a connecting cable. To mount the
CPU-Mounting Programming Console or any other peripheral device directly
to the CPU, follow these steps:

1. Detach the cover of the peripheral device connector with a standard

screwdriver.

2. Connect the CPU-Mounting Programming Console to the peripheral de-

vice connector.

3. To ensure a positive connection, secure the Programming Console to

the CPU by tightening the mounting screws located on the surface of the
CPU.

2-8 Memory Packs

The Memory Pack fits into the slot located on the left side of the CPU. Be­cause the Memory Pack is not provided with the PC upon delivery, a Memory
Pack must be selected and installed in the CPU. There are two Memory
Packs available, either RAM or ROM, that can be used in the C500H PC.

RAM Pack

Data can be randomly written to and read from the RAM Pack, making it pos­sible to enter your own program into the CPU. However, because this is not a
fixed program, the memory of the RAM Pack is erased when power is not
supplied to the CPU or when the RAM Pack is removed from the CPU.

Caution Do not remove the battery in the CPU when the RAM Pack has been removed

from the CPU.

Introduction

When we speak of a PC, we usually think of it as a single object. But actually
even the simplest PCs are usually composed of several different devices. In
fact a single PC can be physically spread throughout a building, but we still
call it one PC.

In this section, we will start with a Backplane and use all the Units discussed

Section 2 Description of All Components

in

3-1 Mounting the Units

There is no single Unit that can be said to constitute a Rack PC. To build a
Rack PC, we start with a Backplane. The Backplane for the C500 is shown
below.

Section 3Assembly

to build a PC.

C500 Backplane

The Backplane is a simple device having two functions. The first is to provide
physical support for the Units to be mounted to it. The second is to provide
the connectors and electrical pathways necessary for connecting the Units
mounted to it.

The first device we will add to the Backplane is a Power Supply. The Power
Supply fits into the rightmost position on the Backplane and provides electric­ity at the voltages required by the other Units of the PC. It can also be used
to power devices other than the PC if necessary.

Power Supply

The core of the PC is the CPU. The CPU contains the program consisting of
the series of steps necessary for the control task. The CPU fits into the posi­tion directly to the left of the Power Supply.

22

CPU

Section 3Assembly

Unlike the CPU of the Package-type PC, the CPU of the Rack PC has no I/O
points built in. So, in order to complete this kind of PC we need to mount one
or more I/O Units to the Backplane. Mount the I/O Units to the Backplane by
pressing the I/O Unit firmly into position, making sure the connectors are
properly mated. Secure the Unit by tightening the mounting screws located
on the top and bottom of the Unit.

Mounting screws
Provided at the top and
bottom of the Unit

Connector
Make sure the connectors
are properly mated.

The figure below shows one I/O Unit mounted directly to the left slot of the
CPU Rack.

I/O Unit

I/O Units are where the control connections are made from the PC to all the
various input devices and output devices. As you can see from the figure,
there is still some space available on the right side of the Backplane. This
space is for any additional I/O Units that may be required.

The figure above shows a total of eight I/O Units mounted to the Backplane.
Backplanes are available in different lengths, and can hold a different number
of I/O Units accordingly. Of course, not all I/O Units look exactly alike, but the
ones in the figure show their typical appearance. This configuration of Back­plane, Power Supply, CPU, and I/O Units is called a CPU Rack. This term
refers to the Backplane and all the Units mounted to it. However, if we want
to include more than eight I/O Units in our configuration we can add an addi-

23

Section 3Assembly

tional Backplane. First, though, we have to mount an I/O Control Unit to the
leftmost slot of the CPU Rack.

I/O Control Unit

Now we can use a cable to connect the CPU Rack to another Backplane.
This Backplane has a Power Supply and I/O Units mounted to it, but it has no
CPU of its own. The additional Backplane must also have an I/O Interface
Unit mounted to its leftmost position. This configuration of additional Back­plane, Power Supply, I/O Units, and I/O Interface Unit is called an Expansion
I/O Rack.

CPU Rack

Expansion I/O Rack

I/O Interface Unit

The CPU Rack and Expansion I/O Rack shown above are connected by a
cable. Remember that this whole configuration is still referred to as one PC.
It is possible to keep adding Expansion I/O Racks in this way until the maxi­mum number of I/O points for the system is reached. Each Expansion I/O
Rack needs an I/O Interface Unit.

The CPU has a removable Memory Pack that stores the user program. Two
Memory Packs are available, in either RAM or ROM. You can write your own
program into the RAM Pack or you can copy a program that has already
been written to an EPROM chip and mount it in the ROM Pack. The EPROM
Chip must be mounted to the PROM Writer in order for the program to be
written to it. Then the EPROM Chip must be mounted to the ROM Pack.

Mounting the EPROM
Chip to the ROM Pack

Depending on the amount of memory required for your application, use 1, 2,
or 3 chips. Refer to
EPROM chips.

Using the diagram and the table below as a reference, mount the EPROM
chips to the correct IC sockets.

The terminal block of an I/O Unit can be removed by loosening the mounting
screws. You do not have to remove the lead wires from the terminal block in or­der to remove it from an I/O Unit.

Note Putting I/O Lines and high-tension lines or power lines in the same

duct or conduit may cause the I/O Lines to be affected by noise. This
may cause a malfunction in the I/O Unit or may cause damage to the
I/O Unit or I/O devices.

Loosen the terminal block mounting screws to remove
the terminal block from the I/O Unit. Make sure the
mounting screws on the terminal block are tightened af­ter wiring is complete, and the terminal block is re­mounted to the I/O Unit.

Wiring Examples

DC Input Units

Note When a Triac Output Unit is used to drive a low-current load, the load

may not turn completely OFF due to a leakage current. To compen­sate for the leakage current, connect a bleeder resistor in parallel
with the load.

The following are examples of how to connect I/O devices to I/O Units. During
wiring, work slowly and carefully. If an input device is connected to an Output
Unit, damage may result. Check all I/O devices to make sure they meet the
specifications (refer to

Section 5Installation Environment

This section details the necessary environment and conditions for installation
of the PC. For specific instructions on mounting Units and wiring for I/O and
power, refer to

electrostatic charge, especially when the humidity is low . Before touching the PC
be sure to first touch a grounded metallic object, such as a water pipe, in order to
discharge any static build-up.

There are two points to consider in order to ensure that the PC does not
overheat. The first is the clearance between the Racks, and the second is
installation of a cooling fan.

The Racks need to have sufficient room between each other to allow for I/O
wiring, and additional room to ensure that the I/O wiring does not hamper
cooling. However, the Racks must be mounted so that the length of the con­necting cable does not exceed 2 m, and the total length of the Connecting
Cables between all Racks does not exceed 12 m. For details about cable
lengths, refer to

devices, and output devices. All Racks of the PC may be connected to one
power source.

The Line Ground (LG) terminal is a noise-filtered neutral terminal that does
not normally require grounding. If electrical noise is a problem, however, this
terminal should be connected to the Ground (GR) terminal.

Power Failure

To avoid electrical shock, attach a grounded (earth ground) AWG 14 wire

ground must be less than 100 Ω. Do not use a wire longer than 20 m. Care
must be taken, because ground resistance is affected by environmental con­ditions such as soil composition, water content, time of year, and the length
of time since the wire was laid underground.

PC operation may be adversely affected if the ground wire is shared with
other equipment, or if the ground wire is attached to the metal structure of a
building. When using an Expansion I/O Rack, the Rack must also be
grounded to the GR terminal. The same ground can be used for all connec­tions.

A sequential circuit is built into the PC to handle power interruptions. This
circuit prevents malfunctions due to momentary power loss or voltage drops.

The PC ignores all momentary power failures if the interruption lasts no

of the rated voltage for longer that 25 ms (less for the DC Power Supply), the
PC will stop operating and the external outputs will be automatically turned
OFF. Operation is resumed automatically when the voltage is restored to
more than 85% of the rated value.

The following diagrams show the proper way to connect the power source to
the PC. The terminals marked “NC” are not connected internally.

Introduction

Interlock Circuits

Section 7Safety Considerations

There are certain safety requirements to be considered when installing the
PC. Some of these, such as the emergency stop circuit (refer to

), are part of the initial wiring. The considerations described below should

ply

be kept in mind when operating the PC and when connecting I/O devices to
the PC.

When the PC controls an operation such as the clockwise and counterclock­wise operation of a motor, provide an external interlock such as the one
shown below to prevent both the forward and reverse outputs from turning
ON at the same time.

This circuit prevents outputs MC1 and MC2 from both being ON at the same
time. Even if the PC is programmed improperly or malfunctions, the motor is
protected.

The 24 VDC output of the CPU and Expansion I/O Power Supply may be
used to power other devices. The output current of these supplies is limited
to 0.3 A. A separate Power Supply must be provided if the devices being
powered require a higher current.

When two-wire sensors, such as photoelectric sensors, proximity sensors or
limit switches with LEDs are connected to the PC as input devices, the input
bit may be turned ON erroneously by leakage current. In order to prevent
this, connect a bleeder resistor across the input as shown below.

If the leakage current is less than 1.3 mA, there should be no problem. If the
leakage current is greater than 1.3 mA, determine the value and rating for the
bleeder resistor using the following formulas.

When connecting a transistor or triac Output Unit to an output device having
a high surge current (such as an incandescent lamp), care must be taken to
avoid damage to the Output Unit. The transistor and triac Output Units are
capable of withstanding a surge current of ten times the rated current. If the
surge current for a particular device exceeds this amount, use the circuit
shown below to protect the Output Unit.

Another way of protecting the Output Unit lets the load draw a small current
(about one third the rated current) while the output is OFF, significantly re­ducing the surge current. This circuit (shown below) not only reduces the
surge current, but also reduces the voltage across the load at the same time.

When connecting TTL circuits to transistor Output Units, connect a pull-up
resistor and a CMOS IC between the two. This is because of the residual
voltage left on the transistor output after the output turns OFF.

Section 7Safety Considerations

When an inductive load is connected to an I/O Unit, connect a surge sup­pressor or diode in parallel with the load as shown in the following diagram.
This is so that the back electromagnetic field generated by the load will be
absorbed.

Take appropriate measures when any electrical device likely to produce
noise is connected to the PC as a load. Devices generating noise of more
than 1,200 V (such as electromagnetic relays and valves) require noise sup­pression. For noise sources running on AC power, connect a diode in parallel
with the coil of each device.

52

When mounting a CPU Rack and an Expansion I/O Rack together on a
mounting plate, provide a solid ground to the mounting plate. The mounting
plate must be plated with a highly conductive surface in order to ensure noise
immunity.

DC Input Unit
3G2A5-ID212

Connection Example 1
(Keyboard)

Appendix BSpecifications

In the case where a large number of bits must be controlled, an ID212 DC
Input Unit can simplify wiring by controlling up to 64 bits through only 16
points. Using digital switches or a specially wired keyboard, different combi­nations of points can access specific bits and words. Two examples of con­nections using digital switches or a keyboard are given.

The table below shows how the ID212 DC Input Unit can be wired using a
specially wired keyboard. For example, if A on the keyboard is pressed, the
combination of DATA0 and STB 9 turn ON bit 00, word n. Similarly, the com­bination of DATA 7 and STB 7 turn ON bit 15, word n+3. The value of word n
depends on where the Unit is mounted on the Rack. For details, refer to the
C500 Operation Manual.

Note Because the DC Input Unit is operated on an extremely small cur-

rent, make sure there is adequate distance between the DC Input
Unit wires and high-tension equipment or power lines. If this cannot

66

Specifications Appendix B

be avoided, use shielded cables when wiring the DC Input Unit. Be
sure to keep the total length of the wires less than 10 m.

Connection Example 2
(Digital Switches)

This example shows how the ID212 DC Input Unit can be wired using digital
switches. Just as the keys on the keyboard can access different combina­tions of words and bits, the digital switches can access different combinations
of words and bits. For example, the combination of switch no. 1 and point 00
access word bit 00, word n.

However, for the sake of simplicity the figure below shows the digital switches
wired to control 32 bits instead of 64 bits as was shown in Example 1. Wire
STB 4, STB 5, STB 6, and STB 7 to access an additional 32 bits.

By using the OD211 DC Output Unit, a large number of bits can be controlled
through only 16 points. Just like the ID211 DC Input Unit, different combina­tions of points can access bits and words to control different outputs. Using
this type of Unit can simplify wiring when many bits must be controlled. Up to
64 bits can be accessed.

Because the output data is positive logic, the terminal output goes high when
the output data is logical 1. The strobe output is negative logic, so when a
signal is output, the corresponding terminal goes low. Use positive logic out­put devices for the load of this Unit. The strobe output is cyclically and auto­matically output.

Note Because the DC Input Unit is operated on an extremely small cur-

rent, make sure there is adequate distance between the DC Input
Unit wires and high-tension equipment or power lines. If this cannot
be avoided, use shielded cables when wiring the DC Input Unit. Be
sure to keep the total length of the wires less than 10 m.

The maximum current value allowed per point differs depending on the ambi­ent temperature and the number of points per common that are ON simulta­neously. The graph below shows the relationship between the allowable cur­rent per point and the number of points ON per common. Be sure not to ex­ceed the values depicted in the graph.

The graph below shows the value of an surge current and the time it takes
the current to level to a steady stream of current (current-carrying time). The
curved line in the graph represents the maximum value of surge current at
which the Unit can operate properly. It is suggested that when opening and
closing a load with a large surge current, to keep the value of the surge cur­rent to half the value shown the graph (within the shaded area).

I/O Connecting Cables

Use an I/O Connecting Cable to connect the CPU Rack to an Expansion I/O
Backplane or to connect an Expansion I/O Backplane to additional Expansion
I/O Backplane.

Fasten the connectors with the locks provided on the connectors to secure
the connection between the cable connector and the connector on the Back­plane. If the connectors are not properly connected or the I/O Connecting
Cable is disconnected during CPU operation, errors such as I/O BUS error
and I/O SETTING error will occur.

Lock springLock spring

The length of the connecting cable depends on the distance between the two
Racks to be connected. The length of the cable should be approximately 20
cm longer than the distance between the two Racks.
