1-1 Features
Miniature High-performance The SP-series PCs are extremely compact yet have a programming capacity
of about 100 instructions in the SP10 or about 240 instructions in the SP16
and SP20. The SP10 is equipped with 34 different instructions and the SP16
and SP20 are equipped with 38 instructions. With real programming capability in such a small package, these compact PCs are ideal for mounting in a
control box or in the device being controlled.
High-speed Processing The minimum instruction execution time is as short as 0.2 microseconds. The
input delay is only 400 microseconds.
Low Maintenance The user program is automatically transferred from RAM to EEPROM, elimi-
nating the need to back up memory, which can be rewritten up to 5,000
times.
Input Signal Filter To prevent errors due to chattering or external noises on input signals, the
input circuits are provided with filter timers that can be set to 0, 1, 5, or 10
ms.
Efficient Distributed Control Up to four SP-series PCs can be connected with a Link Adapter. A total of
128 points can be linked between the PCs, which means that up to 32 points
can be processed by one SP-series PCs. Each PC still operates according to
its own program.
Easy-to-use Analog Timers One analog timer is provided with the SP10 and two analog timers are pro-
vided with the SP16 and SP20. The set time of these analog timers can be
changed even while the PC is operating, with adjustment screws located inside the front cover.
Reversible Drum Counter A reversible drum counter can be programmed for various counter present
value ranges.
Step Instructions Up to five steps (four processes) of instructions can be created, making it
easy to program start-stop control.
Shift Register A 16-bit shift register can be used to control various operations easily.

1-2 PC Basics
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.
2
PC Basics Section 1-2
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 SP-series PCs use a form of PC logic called
ladder-diagram programming. The next few sections will explain ladder-diagram programming and to prepare you to program and operate the SP-series
PCs.
Relay Circuits: The Roots
of PC Logic
Relay vs. PC Terminology
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.
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 terms used for OMRON PCs.
contact input or condition
coil output or work bit
NO relay normally open condition
NC relay normally closed condition
The terms used for PC will be described in detail later.
1-2-1 PC Terminology
Although also provided in the
ing terms are crucial to understanding PC operation and are thus explained
here.

Inputs and Outputs
A device connected to the PC that sends a signal to the PC is called an input device; the signal it sends is called an input signal. A signal enters the
PC through terminals or through pins on a connector on a Unit. The place
where a signal enters the PC is called an input point. This input point is allocated a location in memory that reflects its status, i.e., either ON or OFF. This
memory location is called an input bit. The CPU, in its normal processing
cycle, monitors the status of all input points and turns ON or OFF corresponding input bits accordingly.
3
PC Basics Section 1-2
There are also output bits in memory that are allocated to output points on
Units through which output signals are sent to output devices, i.e., an output bit is turned ON to send a signal to an output device through an output
point. The CPU periodically turns output points ON or OFF according to the
status of the output bits.
These terms are used when describing different aspects of PC operation.
When programming, one is concerned with what information is held in
memory, and so I/O bits are referred to. When talking about the Units that
connect the PC to the controlled system and the places on these Units where
signals enter and leave the PC, I/O points are referred to. When wiring these
I/O points, the physical counterparts of the I/O points, either terminals or connector pins, are referred to. When talking about the signals that enter or
leave the PC, one refers to input signals and output signals, or sometimes
just inputs and outputs. It all depends on what aspect of PC operation is being talked about.
Controlled System and
Control System
The Control System includes the PC and all I/O devices it uses to control an
external system. A sensor that provides information to achieve control is an
input device that is clearly part of the Control System. The controlled system
is the external system that is being controlled by the PC program through
these I/O devices. I/O devices can sometimes be considered part of the controlled system, e.g., a motor used to drive a conveyor belt.
1-2-2 Overview of PC Operation
The following are the basic steps involved in programming and operating the
SP-series PCs. 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. The rest of the steps are described later in this manual.

1. Determine what the controlled system must do, in what order, and at
what times.
2. Determine what size of system is required, i.e.,will a single CPU suffice
or will a Link Adapter be required to join multiple CPUs.
3. On paper, assign all input and output devices to I/O points on the CPUs
and determine which I/O bits will be allocated to each. (

Control System Design
4
Designing the Control System is the first step in automating any process. A
PC can be programmed and operated only after the overall Control System is
understood. Designing the Control System requires, first of all, a thorough
understanding of the devices that are to be controlled. The first step in de-
Units Section 1-3
signing a Control System is thus determining the requirements of the controlled system.
Once the entire Control System has been designed, the task of programming, debugging, and operation as described in the remaining sections of
this manual can begin.
Input/Output Requirements
Sequence, Timing, and
Relationships
Note Programs and Peripheral Devices are not compatible between the SYSMAC
1-3 Units
1-3-1 CPU
The first thing that must be assessed is the number of input and output points
that the controlled system will require. This is done by identifying each device
that is to send an input signal to the PC or which is to receive an output signal from the PC.
Next, determine the sequence in which control operations are to occur and
the relative timing of the operations. Identify the physical relationships between the I/O devices as well as the kinds of responses that should occur
between them.
For instance, a photoelectric switch might be functionally tied to a motor by
way of a counter within the PC. When the PC receives an input from a start
switch, it could start the motor. The PC could then stop the motor when the
counter has received a specified number of input signals from the photoelectric switch.
Each of the related tasks must be similarly determined, from the beginning of
the control operation to the end.
SP-series PCs and C-series PCs.
This section presents the names and functions of the various components of
the CPU, Programming Console, and Link Adapter.
The SP-series PCs are shown below. Four models are available for each:
two powered by a 100- to 240-VAC power supply and the other two powered
by a 24-VDC power supply. Refer to

Units Section 1-3
The Programming Console is used to write and transfer programs to the PC.
It is also used to monitor operation and modify data. The Programming Console can be connected directly to the PC for single PCs. It can also be connected via a Link Adapter when PCs are connected in a PC Link configuration to access each PC individually without reconnection.
Note PCs connected to a Link Adapter cannot be directly connected to a Program-
ming Console. The Programming Console is connected to the Link Adapter.
1-3-3 Link Adapter
The Link Adapter is shown below. The Link Adapter is used to link up to four
CPUs so that data can be transferred between the CPUs and so that all of
the CPUs can be accessed from the Programming Console from a single
connection point. For details refer to
1-4 PC Configuration

1-3-4 Memory Cards
The Programming Console provides the ability to backup programs. The
Memory Card slot located at the base of the keyboard allows programs to be
transferred directly to and from the Programming Console. Each Card has a
built-in battery to preserve data.
Only one model of Memory Card, HMC-ES141, may be used. Each Memory
Card has 16 Kbytes of S-RAM. One Memory Card can hold up to 26 SP10
programs or up to 18 SP16 or SP20 programs.
A battery is built-in to the Memory Card to allow the data to be retained. The
battery must be replaced within five years to ensure data is not lost. To remove the battery, insert a sharp object, like a pen tip, into the hole at the bottom right of the card. The new battery must be inserted within one minute of
removing the old one.
Memory Cards have a write-protect switch. When the switch is ON, writing
operations to the memory card will not be possible.
Caution While the Memory Card is being accessed, the M/C ON LED on the Program-
!
ming Console will be lit. If the Memory Card is removed out from the Programming Console while the LED is ON, the data contained in memory on the Card
may be damaged.
WARNING Do not short the positive and negative terminals, charge, take apart, or throw
!
into fire a Memory Card. The battery inside the card may explode, burst into fire,
or leak, causing a potentially dangerous or even fatal accident.

PC Configuration Section 1-4
1-4 PC Configuration
The SP-series PCs can be configured to control a control system of from 10
through 80 I/O points. An SP10 provides 10 I/O points (6 input and 4 output
points), an SP16 provides 16 I/O points (10 input and 6 output points), and
an SP20 provides 20 I/O points (12 input and 8 output points). A maximum of
4 SP-series PCs can be linked together via a Link Adapter, making a maximum of 80 I/O points with 4 SP20s.
1-4-1 Basic Configuration
When only one SP-series PC is used, the number of I/O points available is
10 with the SP10, 16 with the SP16, or 20 with the SP20. Here, the Programming Console is connected directly to the CPU for programming and operation.
Connecting Cable
SP10-CN__1

SP10-PRO01-V1
1-4-2 Expanded System Configuration: PC Links
Up to four PCs can be linked with a Link Adapter to increase the number of
I/O points to 80 maximum. Although each PC still operates on its own program, no special programming is needed to transfer data between the PCs
via LR bits. Up to 128 bits of data (32 bits per PC) can be shared between
the PCs through their LR areas. Refer to

PC Configuration Section 1-4
Note 1. When two or more PCs are linked, apply power to all of the PCs at once
or to PC #0 last.
2. When using a Link Adapter, one PC must be connected to connector
number 0 on the Link Adapter.
3. Once CPUs are connected to the Link Adapter and turned ON, unit num-
bers are automatically assigned to the CPUs by the Link Adapter. Do not
change the point of connection of any CPU after a unit number has been
assigned to it. If CPUs are connected to a connecter for a different unit
number, unpredictable errors will occur during operation.
Unit Numbers When four PCs are linked, each are given a number from 0 through 3 de-
pending on which connector on the Link Adapter is used. PC #0 controls LR
data transfers between the PCs. The Programming Console is connected to
the Link Adapter and can program and monitor any of the four PCs.

2-2 Installation
2-2-1 Installation Environment
Although the SP-series Programmable Controllers are highly reliable and
durable, a number of factors should be considered when installing them. Do
not expose an SP-series PC to the following conditions.
13
Installation Section 2-2
• An ambient temperature that falls below 0° or exceeds 55°C for the CPU, or
that falls below 0°or exceeds 45°C for the Programming Console.
• Abrupt changes in temperature that cause condensation.
• A relative humidity less than 10% or greater than 90%.
• Corrosive or flammable gas.
• Dust, salt, or iron particles.
• Direct vibration or shock.
• Direct sunlight.
• Splashes of water, oil, or chemicals.
2-2-2 Cooling
There are two points to consider in order to ensure that the PC does not
overheat. The first is the clearance between the CPUs and control panel surround them, and the second is the installation of a cooling fan.
Clearance The CPUs need to have sufficient room between them to allow for I/O wiring,
and additional room to ensure that the wiring does not hamper cooling. The
CPU’s must be mounted close enough so that the length of the Connecting
Cable between any CPU and the Link Adapter does not exceed 4 meters.
Cooling Fan Ensure adequate ventilation is provided for the PCs. A cooling fan is not al-
ways necessary, but may be needed if the PC is mounted in a warm or enclosed area or over a source of heat. Although it is best to avoid installing the
PC in a warm area, use a cooling fan or an air conditioner, as shown in the
following illustration, to maintain the ambient temperature within specifications.
2-2-3 Preventing Noise
In order to prevent noise from interfering with the operation of the PC, use
AWG 14 twisted-pair cables (cross-sectional area of at least 2 mm
mount the PC in a control panel in which high-power equipment is installed
and make sure the point of installation is at least 200 mm away from power
cables, as shown in the following diagram. Ground the panel to which the PC
is mounted.

Wiring Section 2-3
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.
2-2-4 Mounting Requirements
The system consists of from one to four CPUs and, if more than one CPU is
used, a Link Adapter. The Units may be mounted horizontally or vertically, as
desired. Do not mount a Unit on its side. The Unit should be mounted with
the printing on the front panel oriented as it would normally be read. The PC
can be mounted using DIN Track or mounted directly to any sturdy support
meeting the environmental specifications listed in
Track Mounting The PC may be mounted using DIN Track if desired. Use DIN Track 35 mm
wide. There is a groove on the back of the Unit that is used to attach it to the
DIN Track. When mounting to DIN Track, be sure to remove the mounting
screws.
Appendix B Specifications.
RemovalMounting
Note Remove the mounting screws when mounting on a track.
2-3 Wiring
Note Do not wire the terminal marked “NC.”
2-3-1 Power Supply
Screwdriver
Engage the top hook to the
track and push the PC in until
the bottom hook locks onto the
track.
Push down the bottom hook
with a screwdriver and push
the PC upward.
Attach an End Plate to the left and right sides of the Unit to hold it in place.

Use independent power sources for the inputs, the output loads, and the PC.
Voltage fluctuations caused by current surges to motors may affect operation
of the PC. When using more than one PC, use a separate power supply for

each PC, firstly to prevent voltage drops caused by surge currents and secondly, to prevent the breaker from malfunctioning.
The following diagrams show the proper way to connect the power source to
the PC. Refer to

area of 1.04 to 2.63 mm
self-rising pressure plates. Connect the lead wires to the terminals as shown
below. Tighten the screws with a torque of 8 kg-cm maximum.
If you wish to attach solderless type terminals to the ends of the lead wires,
use terminals having the following dimensions.

The power source of the SP10 for external supply is rated at 0.1 A, 24 VDC
max., and the power source of the SP16 and SP20 is rated at 0.2 A, 24 VDC
max. The input circuit consumes about 7 mA (typ. at 24 VDC) per input point.
Transistor outputs with a current consumption up to 0.2 A can be used with
the SP10, and a current consumption up to 0.32 A with the SP16 and SP20.
Relay contact outputs require a current of 0.013 A each, so when all of the
relays are ON, the external power supply capacity is 0.1 A for the SP10 and
0.2 A for the SP16 and SP20. When using the SP10 as the power source for
Wiring Section 2-3
input devices such as sensors, etc., make sure that the power consumption
of the devices does not exceed the ratings of the PC.
DC Input Examples The following diagrams show the correct way to wire the terminals on the
CPU. When wiring, work carefully to ensure that all terminals are wired correctly. If an input device is connected to an output point, damage may result.

The DC inputs in the following diagrams are NPN (positive common). Reverse the polarity if PNP (negative common) is used.
Use the CPU’s 24 VDC power supply output to supply power to inputs. If the
maximum output current of 0.3 A is not sufficient, use a separate DC power
supply.

OFF). Proper operation for power interruptions will not be possible if NC contacts are used in conjunction with counter, shift, or keeping (latching) instructions.
2-3-3 Precautions
Unit Sticker A sticker is provided on the upper face of the CPU to prevent foreign objects,
such as wire clippings, from entering the CPU. Leave this protective sticker
on until the CPU is ready for operation. The sticker must be removed before
operation to enable proper cooling.
Contact Outputs High inductance on for contact outputs will reduce relay life. Keep inductance
low and use an arc suppressor (such as a diode for DC loads). This is particular important with inductive DC loads.
Vibration Relay operation may be adversely affected if the relay is located near contac-
tors, valves, motors, or other devices that produce vibration.
Protective Circuits We recommend the use of arc suppressors to increase contact life and allevi-
ate the affects of noise. Arc suppressors, however, will delay release time
somewhat and, if used incorrectly, they can inhibit proper operation. The
most common arc suppressors for AC are capacitor-resistor circuits and varistor circuits; for DC: capacitor-resistor circuits, diode circuits, and varistor
circuit. Do not use a capacitor without a resistor as the charging current flow
to the capacitor when current is turned ON can cause the contacts to fuse.
