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.

Stepping Motor

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.

etc.

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.

with a total current consumption of 7A to a Rack supplied by a 7 A Power Supply.
As shown in the table above, the available current for I/O Units is only 6.5 A. For
details concerning current consumption, refer to Section 4 System Connections.
