necting to a ground of 100 Ω or less may result in electric shock.

• Always turn OFF the power supply to the PC before attempting any of the fol-

lowing. Not turning OFF the power supply may result in malfunction or electric
shock.

• Mounting or dismounting I/O Units, CPU Units, Memory Units, or any other
Units.

• Assembling the Units.

• Setting DIP switches or rotary switches.

• Connecting cables or wiring the system.

• Connecting or disconnecting the connectors.

Caution Failure to abide by 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.

• Interlock circuits, limit circuits, and similar safety measures in external circuits
(i.e., not in the Programmable Controller) must be provided by the customer.

• Always use the power supply voltages specified in this manual. 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.

• Install external breakers and take other safety measures against short-circuit­ing in external wiring. Insufficient safety measures against short-circuiting may
result in burning.

5Application Precautions

• Do not apply voltages to the Input Units in excess of the rated input voltage.
Excess voltages may result in burning.

• Do not apply voltages or connect loads to the Output Units in excess of the
maximum switching capacity. Excess voltage or loads may result in burning.

• Disconnect the functional ground terminal when performing withstand voltage
tests. Not disconnecting the functional ground terminal may result in burning.

• Be sure that all the mounting screws, terminal screws, and cable connector
screws are tightened to the torque specified in this manual. Incorrect tighten­ing torque may result in malfunction.

• Double-check all wiring and switch settings before turning ON the power sup­ply. Incorrect wiring may result in burning.

• Mount Units only after checking terminal blocks and connectors completely.

• Be sure that the terminal blocks, Memory Units, expansion cables, and other

items with locking devices are properly locked into place. Improper locking
may result in malfunction.

• Check the user program for proper execution before actually running it on the
Unit. Not checking the program may result in an unexpected operation.

• 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.

• 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.

• Check the direction and polarity of all terminal blocks and connectors before
attempting to connect them.

What is a Control System? Section 1-1

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.

Control Components

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

The Role of the PC Section 1-2

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: micro-switches, 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.

1-2-2 Output Devices

Photoelectric Switch

Proximity Switch

Limit Switch

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.

How Does a PC Work? Section 1-3

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 scans the
program in its memory to achieve this control.

Signals to

etc.

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.

Scanning Cycle 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, 2, 3... 1. Common (or overseeing) processes, such as watchdog timer operation and

testing the program memory.

2. Data input and output.

3. Instruction execution.

4. Peripheral device servicing.

Cycle Time The total time required for a PC to perform all these internal operations is called

the cycle time. The flowchart and diagram on the following page 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?

• 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.

2-1 CPU Rack

The following figures show the names of all the parts of the CPU Racks used in
C1000H and C2000H Systems. Note that the Backplanes used for each system
are different.

C1000H System There are seven models of CPU Racks available for C1000H systems. Choose

a Backplane with 3, 5 (2 models), 6, 8 (2 models), or 9 I/O slots, depending on
your application. Connect the CPU Backplane to an Expansion I/O Rack via the
Expansion I/O Connector.

CPU Power Supply

C2000H Simplex System The C2000H Simplex CPU Rack is different from the C1000H CPU Rack in that

there are six slots available for I/O Units rather than eight. The CPU Rack for the
Simplex and Duplex Systems have a special slot, to the left of the I/O Units, for
an I/O Remove Unit. Connect the CPU Rack to an Expansion I/O Rack via the
Expansion I/O connector. For more details concerning the Simplex System,
refer to Section 3-3 C2000H Simplex System.

C2000H Duplex System The C2000H Duplex CPU Rack is different from both the C1000H and C2000H

Simplex CPU Racks. The CPU Rack houses two CPUs and a Duplex Unit, learn­ing no room for I/O Units. An additional Rack connected to the CPU Rack via the
Expansion I/O Connectors accommodates the I/O Units which would normally
be mounted to the CPU Rack. Note that two connecting cables are required to
connect the CPU Rack to the accompanying I/O Rack that houses the I/O Units.
Just like the Simplex System, the Duplex CPU Rack has a special slot for an I/O
Remove Unit, located on the I/O Backplane.

I/O Backplane Section 2-3

2-3 I/O Backplane

The I/O Backplane is always paired with the CPU Rack in a C2000H Duplex sys­tem. The I/O Backplane houses the I/O Units, which cannot be mounted to the
CPU Rack. Use two cables to connect the I/O Backplane to the CPU Rack. Two
PC Link Units and one Host Link Unit can be mounted to any of the six rightmost
slots on the I/O Backplane. Similar to the C2000H CPU Backplane, the I/O Back­plane also has a special slot for an I/O Remove Unit. Use one cable to connect
the I/O Remove Unit on the I/O Backplane to the I/O Remove Unit on the Expan­sion I/O Rack.

2-4 Expansion I/O Backplane

The Expansion I/O Backplane shown in the following diagram, can be used to
expand the C1000H and C2000H Simplex and Duplex Systems. An Expansion
I/O Rack is just like a CPU Rack, except a CPU is not mounted. However, a
Power Supply is needed for each Expansion I/O Rack. There are three models
of Expansion I/O Backplane available. The Expansion I/O Rack shown below
can only be used with C2000H Systems. This Backplane has a special slot for
the I/O Remove Unit, which allows on-line I/O Unit exchange. two models are
available for C1000H PCs, with either five or eight slots.

2-6 Duplex Unit (C2000H Duplex)

The Duplex Unit shown below must be mounted to the CPU Rack in order to
operate the Duplex System. The following indicators and switches are located
on the front panel.

DUPLEX RUN (Green)
Lit during normal duplex
operation

DUPLEX BUS ERROR (Red)
Lit if an error occurs in the Duplex
System. When a DUPLEX BUS
ERROR occurs the active CPU
switches the system from a Duplex
System to a Simplex System.

VERIFY ERROR (Red)
Lit if the programs in both CPUs are
not the same. When a VERIFY
ERROR occurs, the active CPU
switches the system from a Duplex
System to a Simplex System.

ACTIVE CPU (Green)
Indicates which CPU is active.

CPU RUN (Green)
Lit when the active CPU is
operating normally.

WAITING (Green)
This indicator is lit on three different
occasions:
(1) While the program in the Duplex
System is being verified (1 to 20
seconds)
(2) When the start input is not applied
to the CPU
(3) When there is a failure in starting
the Duplex System

CPU ON/OFF switches
Use these switches to supply power to
each of the CPUs. To operate the CPU,
move the corresponding switch to the
ON position. When replacing the CPU,
move the corresponding switch to the
OFF position, and remove the CPU
from the Rack. Note that power is not
supplied to the CPU whose corre­sponding switch is OFF.

2-7 I/O Control Unit

An I/O Control Unit must be mounted to the CPU Rack in order to connect the
CPU Rack to an Expansion I/O Rack. In C1000H and C2000H Simplex Sys­tems, the I/O Control Unit is mounted to the CPU Rack. In the C2000H Duplex
System, the I/O Control Unit is mounted to the I/O Rack. An I/O Control Unit can
be mounted even if no Expansion I/O Rack is used.

2-8 I/O Interface Unit

An I/O Interface Unit is needed on each Expansion I/O Rack, in order to expand
the PC. If there is not an I/O Interface Unit on each Expansion I/O Rack, data
communication cannot take place. The I/O Interface Unit is mounted to the left­most I/O position on the Expansion I/O Backplane.

18

I/O Remove Unit Section 2-11

2-9 File Memory Unit

When a File Memory Unit is connected to the PC, contents of the Program
Memory and data areas can be transferred to and from File Memory (FM). For
details on operating the File Memory Unit, refer to the C1000H/C2000H Opera-
tion Manual.

The Unit can be mounted to either of the six rightmost slots on the Rack.

2-10 Space Unit

The Space Unit is included with the I/O Backplane to fill the space between the
Power Supply and the rightmost Unit mounted on the Backplane. This Unit only
applies to the I/O Backplane used in C2000H Duplex Systems. When mounting
this Unit be sure to remove the bracket on the Backplane first.

2-11 I/O Remove Unit

The I/O Remove Unit is unique to C2000H Systems. When mounted to a Rack of
a C2000H System, the I/O Remove Unit allows standard I/O Units to be removed
or mounted while the CPU is operating. The I/O Remove Units on each Rack are
connected by an I/O Remove Unit Connecting Cable.

In order to mount an I/O Unit to or remove an I/O Unit from any of the Racks in the
PC system, a Programming Console must be used to release the I/O Unit from
the control of the CPU. For details, refer to the PC Operation Manual.

Depending on the combination of I/O Units, a failed standard I/O Unit can be
replaced without affecting the other Units in the system.

When mounting or removing the I/O Units, the terminal block does not need to be
rewired. Simply mount the I/O Unit to the Backplane and then the terminal block
to the I/O Unit. When removing the I/O Unit, remove the terminal block first and
then remove the I/O Unit from the Backplane.

When an I/O Unit is mounted or removed while the CPU is operating on a Back­plane which has an Interrupt Input Unit mounted to it, the Interrupt Input
(mounted only to C1000H and C2000H Simplex PCs) will be ignored.

Note 1. Remember that only a standard I/O Unit can be mounted or removed during

operation.

2. An I/O Remove Unit must be mounted on every Rack that will require I/O
units to be mounted or removed during operation. Even if none of the I/O
Units on the CPU Rack will be removed or mounted during operation, an I/O
Remove Unit is needed if I/O substitution is to take place on an Expansion
I/O Rack connected to the CPU Rack.

19

I/O Units Section 2-12

Special I/O Units, such as the A/D Conversion Input Unit or the High-speed
Counter Unit, cannot be removed or mounted during operation. In addition, if
Special I/O Units and standard I/O Units are mounted on the same Rack, none of
the Units on that Rack can be removed or mounted without affecting the other
Units. However, there are combinations with other I/O Units that allow substitu­tion during PC operation. The following table explains the instances in which
standard I/O Units, when used in combination with other I/O Units, can be
removed or mounted during PC operation. The groups defined in the table are
used only in this section and do not apply to groups of similar nature in other
manuals.

Group I/O Unit Mounted to 3G2C5-BI082 and 3G2C5-BI083 Backplane

Group A 16-/32-/64-point I/O When only Units from Group A are mounted to a Backplane the I/O Units can

be removed or mounted during PC operation.

Group B PC Link Unit

Host Link Unit

Group C A/D Conversion Unit

D/A Conversion Unit
Remote I/O Master

Others

When Units from Group B are mounted on the same Backplane as Units from
Group A, only the Units from Group A can be removed or mounted during PC
operation. However, this does not apply when using 3G2C5-BI083.

When Units from Group C are mounted on the same Backplane as Units from
Group A, neither Group a Units nor Group C Units can be removed or
mounted during PC operation.

Caution When removing or mounting an I/O Unit while the CPU is operating, be sure to

2-12 I/O Units

A-shape

remove the terminal block from the I/O Unit first and then remove the I/O Unit
from the Backplane. If the entire I/O Unit is removed from the Backplane, output
signals are not cleanly disconnected, but may be sent to external devices, caus­ing a sudden pulse to go the external device. This may in turn cause the device to
shudder. Also, when remounting the I/O Unit to the Backplane, fir st mount the
I/O unit and then the terminal Block to the I/O Unit.

I/O Units come in 5 shapes; A-shape, B-shape, C-shape, D-shape, and
E-shape. Refer to Appendix B Specifications for the dimensions of each Unit.

Memory Packs Section 2-13

2-13 Memory Packs

The Memory Pack fits into the slot located on the right 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 for both the C1000H and C2000H
Systems.

Note Mount a Memory Pack to the CPU on the left and another Memory Pack to the

CPU on the right. These Memory Packs must have the same specifications.
When using the RAM Pack, there must not be any difference in write-protect
switch settings for the left and right CPUs, otherwise a collation error will result
and the PC will not operate.

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 without first being con­nected to a backup battery.

Caution

!

1. When removing the RAM Pack from the CPU, be sure to connect the RAM
Pack to a backup battery before removing it from the CPU or the data will be
lost. Do not use the backup battery located in the compartment above the
Memory Unit Compartment. It is used to backup memory in the CPU.

2. Do not remove the battery in the CPU when the RAM Pack has been
removed from the CPU.

There is a write-protect switch and a write-protect indicator on the RAM Pack, as
shown in the following diagram. Setting the write-protect switch to OFF allows
data to be written to the RAM Pack. Use a peripheral device, such as a Program­ming Console, to write to the RAM Pack.

Battery connector

RAM Pack

To write data to the RAM Pack, move the write-protect switch to the OFF posi­tion. After data is written to the RAM Pack, be sure to move the write-protect
switch to the ON position to protect the data from further alterations. If you try to
write data to the Memory Pack while the write-protect switch is in the ON posi­tion, the message DISABLED ROM will appear on the Programming Console.

Four models of RAM Packs are available, which vary in memory capacity: 8K,
16K, 24K, and 32K words. Refer to Appendix C Standard Models for model num­bers.

Memory Packs Section 2-13

ROM Pack Data contained in the ROM Pack is stored on EPROM chips and cannot be

altered or erased during the CPU’s operation. The ROM Pack can accept four
EPROM chips, which can be programmed for your particular application with the
PROM Writer. The EPROM chip is mounted to the Memory Pack and the entire
pack is installed in the CPU. Once the data is written to the chip the data will not
be lost when the power to the PC is OFF.

SECTION 3

Assembly

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 in Section 2 to build a PC.

Mounting the Units Section 3-1

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 C1000H/C2000H is shown
below.

C1000H/C2000H 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.

26

CPU

Mounting the Units Section 3-1

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 I/O Unit. This space is for any
additional I/O Units that may be required.

27

Mounting the Units Section 3-1

The figure above shows a total of six 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 six I/O Units in our configuration we can add an additional 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

28

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.

C2000H Duplex System Section 3-2

3-2 C2000H Duplex System

The C2000H has a unique feature. The C2000H lets you build a PC that uses
two CPUs. This is called a Duplex System. Either CPU, which is mounted to the
CPU Rack, is capable of assuming the system function. One CPU controls the
system while the other CPU assumes a standby status. Consequently, if a failure
occurs in one of the CPUs, the other CPU can take over the system function,
preventing the entire system from halting, The figure below shows a Duplex Sys­tem. Note that the CPU Rack is connected to the I/O Rack by two cables.

CPUs

CPU Rack

Duplex Unit

I/O Rack

While the Duplex System is in operation, one of the two CPUs has “active” status
and the other CPU has “standby” status. The active CPU executes the program
and controls the I/O Units while the standby CPU merely executes the program,
but does not control the I/O Units. The status of the CPUs can be determined by
setting the selector switch on the front panel of the Duplex Unit.

If an error occurs in the active CPU, making further operation impossible, the
standby CPU automatically becomes active and takes over operation. The
failed CPU can be repaired or replaced without having to shut down the entire
CPU.

Operating Mode The operating mode is set through the active CPU. Once the operating mode of

the active CPU is set, the standby CPU is automatically set in same operating
mode as the active CPU.

Peripheral Devices As mentioned, the operating mode can only be set through the active CPU. How-

ever, peripheral devices such as the Programming Console can be mounted to
the standby CPU to monitor operations.

Initial Settings Take the following steps to prepare the Duplex System for operation.

1, 2, 3... 1. Be sure to install identical Memory Packs in both CPUs. Because one of the

CPUs in the Duplex System acts as a standby system, make sure that identi­cal Memory Packs are installed in both CPUs. IF the active CPU can no
longer control the system, the standby CPU can take over the System using
an identical program.

ROM Packs When using ROM Packs, make sure that the same number and
same type of EPROM chips are mounted to both ROM Packs. In addition,
the same program must be written to both ROM Packs.

RAM Packs When using RAM Packs, make sure the Units have the same
memory capacity. Write the program to the RAM Unit installed in the active
CPU. The program written to the active CPU is automatically written to the
memory of the standby CPU when the Duplex System is put into operation.

29

C2000H Duplex System Section 3-2

Note All information previously stored in the RAM Pack of the standby CPU

will be erased when a new program is written to the RAM Pack of the
active CPU.

2. Set the System Switch, located on the front panel of the Duplex Unit, to DPL
(Duplex System) or SPL (Simplex System). As shown below, the switch is
set to DPL to indicate a Duplex System.

CPU ON/OFF switches
Use these switches to supply power to
each of the CPUs. To operate the CPU,
move the corresponding switch to the
ON position. When replacing the CPU,
move the corresponding switch to the
OFF position, and remove the CPU
from the Rack. Note that power is not
supplied to the CPU whose corre­sponding switch is OFF.

ACTIVE SYSTEM
DPL (Duplex)
SPL (Simplex)

INITIAL SET

3. Next, select the active CPU by setting the Active Switch to RIGHT or LEFT.
In the example above, the right CPU is the active CPU.

4. To complete the initial settings, set both CPU ON/OFF selectors on the front
panel of the Duplex Unit to the ON position. If both CPU selectors are not in
the ON position, the Duplex System cannot operate.

When an Error Occurs in
the Duplex System

30

When the Duplex System is put into operation, both CPUs are in the ON position
and an active CPU, either the right CPU or the left CPU, is selected. A Duplex
System is a control system with two operable CPUs, an active CPU and a stand­by CPU, either of which can take over system operation at any time. However, if
an error occurs causing one of the CPUs to fail, the system automatically
changes to a Simplex System, regardless of the switch settings on the front pan­el of the Duplex Unit. For example, if an error occurs in the standby CPU causing

C2000H Duplex System Section 3-2

it to be inoperable, it can no longer be a Duplex System and therefore automati­cally changes to a Simplex System, with only the active CPU controlling the sys­tem.

If there is an error that causes the active CPU to fail, the system again automati­cally changes to a Simplex System, switching control to the operable CPU (the
standby CPU). For example, the switches on the front panel of the Duplex Unit
indicate that the right CPU is active and controlling the I/O Units in a Duplex Sys­tem. If the active CPU fails, the system changes from a Duplex System to a Sim­plex System and the operable standby CPU (in this example, the left CPU) takes
over the system operation and becomes the active CPU. The change from Du­plex to Simplex and from active CPU to standby CPU takes place regardless of
the settings on the front panel of the Duplex Unit.

Switching from Duplex to
Simplex

Select the active CPU and set the AC­TIVE switch to LEFT or RIGHT de­pending on which CPU is to be active.

Set the CPU ON/OFF switch which cor­responds to the active CPU to the ON
position.

The SYSTEM switch is
set to SPL for Simplex

If you are using a Duplex System but want to use only one CPU to write a pro­gram to the memory of the CPU or test the program in the CPU, switch the Du­plex System to a Simplex System.

The flow chart below illustrates how the Duplex System can be changed to Sim­plex operation. The switches referred to in the flow chart are on the front panel of
the Duplex Unit. Assume that there is a Programming Console already mounted
to the active CPU.

Memory Packs Section 3-4

3-3 C2000H Simplex System

The C2000H Simplex System is a PC that operates with only one CPU. The op­eration of the Simplex System is quite similar to that of the C1000H, in that a
maximum of seven Expansion I/O Racks can be utilized to access a maximum of
2,048 I/O points.

One difference can be seen in the CPU Rack. Only six I/O Units can be mounted
to the CPU Rack of the C2000H Simplex System. Also, an I/O Remove Unit, a
feature unique to the C2000H Systems, can be mounted to the CPU and Expan­sion I/O Racks to allow on-line exchange.

3-4 Memory Packs

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.

C2000H Duplex System The CPU Rack for the C2000H Duplex System, unlike the C1000H and the

C2000H Simplex Systems, has two CPUs and a Duplex Unit mounted to it. The
C2000H Duplex System is configured differently from the Simplex System, be­cause it has an additional I/O Rack connected to the CPU Rack to accommodate
the I/O Units. Note that there are two connecting cables that connect the CPU
Rack to the I/O Rack. A maximum of seven Expansion I/O Racks can be con­nected to the I/O Rack, making 1,024 the maximum number of points available
when 16-point I/O Units are used. The number of I/O points is increased to 2,048
when the system is configured with 32-point I/O Units.

The number of Special I/O Units that can be used depends upon the number of points available and
the number of points the Special I/O Unit requires. Be sure to check the current capacity for each I/O
Unit and the CPU.

When using 3G2A5-LK103(-P)/LK203 Host Link Units, a maximum of two Rack-mounting Host Link
Units can be mounted to the CPU Rack or I/O Rack. An additional CPU-mounting Host Link Unit can
be mounted to the CPU, making the total number of Host Link Units three.

When using 3G2A5-LK101-(P)EV1/LK201-EV1 Host Link Units, only one Rack-mounting Host Link
Unit can be mounted to the CPU Rack or I/O Rack. An additional CPU-mounting Host Link Unit can
be mounted to the CPU, making the total number of Host Link Units two.

These Host Link Units cannot be mounted on Expansion I/O Rack.

If the SYSMAC Net Link Unit is mounted, either 3G2A5-LK103(-P) or 3G2A5-LK203 can be mounted
as Rack-mounting Host Link Unit. Both models cannot be mounted at the same time.

from the Rack if there is an I/O Remove Unit mounted to the Rack. Refer to Section 2 Description of
All Components for details.

Install identical Memory Packs in both CPUs, if you are using a C2000H Duplex PC.

Up to eight Remote I/O Master Units can be mounted to both the I/O Rack and the Expansion I/O
Racks. When the Remote I/O Unit is mounted to a Rack, a Rack number must be set so that the CPU
can identify the Remote I/O Unit. Mount the Remote I/O Slave Unit to the leftmost position (the I/O
Interface Unit position) on the Slave Rack. For details, refer to the C1000H/C2000H Operation
Manual.

tional area: 0.3 to 0.75 mm

) for 19-terminal terminal blocks and AWG 22 to lead wire (cross-sec-

) for 10-terminal terminal blocks. The terminals have
screws with 3.5-mm diameter heads and self-raising pressure plates. Connect
the lead wires to the terminals as shown. Tighten the screws to a torque of 0.8
NSm.

Use ring crimp terminals for wiring. Do not connect bare stranded wires directly
to terminal blocks.

7 mm max.7 mm max.

Terminal Block 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 con-

duit 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.

Terminal block mounting screws
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.

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.

43

I/O Connections Section 4-2

Wiring Examples 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 Appendix B Specifications). Be sure to allow for leakage
current and load inductance.

Installation 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 Section 3-5 System Configurations and 4-2 I/O Connections.

Caution Static electricity can cause damage to PC components. Your body can carry an

!

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.

Mounting Requirements Section 5-2

5-1 Cooling

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.

Clearance Between Racks The Racks need to have sufficient room between each other to allow for I/O wir-

ing, 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 Appendix
C Standard Models. As a general rule, about 70 to 120 mm should be left be­tween any two Racks (50 to 100 mm should be left between any two Racks in the
Duplex System).

Cooling Fan A cooling fan is not always necessary, but may be needed in some installations.

Try to avoid mounting the PC in a warm area, or over a source of heat. A cooling
fan is needed if the ambient temperature may become higher than that specified
(refer to Appendix B Specifications). If the PC is mounted in an enclosure install
a cooling fan, as shown in the following diagram, to maintain the ambient tem­perature within specifications.

PC

Louver

5-2 Mounting Requirements

The PC consists of from one to eight Racks, or from one to nine Racks if you are
using the C2000H Duplex System. Each Rack must be mounted vertically, that
is with the printing on the front panels oriented as it would normally read. The
Racks should be mounted one above the other with the CPU Rack uppermost.

Fan

48

The PC may be directly mounted to any sturdy support meeting the environ­mental specifications (refer to Appendix B Specifications).

The duct work shown in the following diagram is not used for mounting the
Racks. Although optional, the duct work can be used to house the wires from the
I/O Units that run along the sides of the Racks, keeping the wires from becoming
entangled with other machines. The figures illustrate the correct way to mount
the Racks.

5-4 Preventing Noise

In order to prevent noise from interfering with the operation of the PC, use AWG

14 twisted-pair cables (cross-sectional area: 2 mm

min.). Avoid mounting the
PC close to high-power equipment, and make sure the point of installation is at
least 200 mm away from power cables as shown below.

Whenever possible, use wiring conduit to hold the I/O wiring. Standard wiring
conduit should be used, and it should be long enough to completely contain the
I/O wiring and keep it separated from other cables.

51

SECTION 6

Power Considerations

Use a commercially available 100 to 120 VAC, 200 to 240 VAC, or 24 VDC power source, according to the model of PC you
are using (refer to Appendix B Specifications). Expansion I/O Racks, if used, must also be connected to the power source. If
possible, use independent power sources for the PC, input devices, and output devices. All Racks of the PC may be connected
to one power source.

53

Power Considerations Section 6

Grounding 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.

To avoid electrical shock, attach a grounded (earth ground) AWG 14 wire (cross­sectional area: 2 mm
be less than 100 W. 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.

Power Failure A sequential circuit is built into the PC to handle power interruptions. This circuit

prevents malfunctions due to momentary power loss or voltage drops. A timing
diagram for the operation of this circuit is shown below.

The PC ignores all momentary power failures if the interruption lasts no longer
than 10 ms. If the interruption lasts between 10 and 25 ms, the interruption may
or may not be detected. If the supply voltage drops below 85% 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.

Wiring The following diagrams show the proper way to connect the power source to the

PC. The terminals marked “NC” are not connected internally.

SECTION 7

Safety Considerations

There are certain safety requirements to be considered when installing the PC. Some of these, such as the emergency stop
circuit (refer to Power Supply), are part of the initial wiring. The considerations described below should be kept in mind when
operating the PC and when connecting I/O devices to the PC.

59

Safety Considerations Section 7

Interlock Circuits 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.

MC2

MC1

Motor clockwise

MC1

Motor counterclockwise

MC2

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.

Power Supply Output 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.

Input Leakage 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.

Output Surge Current 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.

R

OUT

L

+

COM

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.

61

Safety Considerations Section 7

Inductive Load Surge
Suppressor

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.

Resistor: 50 W
Capacitor: 0.47 F
Voltage: 200 V
Diode: Must withstand voltages of more
than three times the load voltage and an av­erage current of 1 A

Electrical Noise 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.

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

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.

Connection Example 1 (Keyboard)

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 STB9 turn ON bit 00, word n. Similarly, the combina­tion of DATA 7 and STB7 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 C1000H/C2000H Operation Manual.

Note Because the DC Input Unit is operated on an extremely small current, 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.

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.

71

Appendix BSpecifications

However, for the sake of simplicity the figure below shows the digital switches wired to control 32 bits instead of 64

Special Considerations for C500-OA225

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).
