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. Doing so may break the cables.

6 Conformance to EC Directives

The

CV

-series PCs that comply with EC Directives must be installed as follows:

1, 2, 3...

1. The

CV

-series PCs are designed for installation inside control panels. The

PC must be installed within a control panel.

2. Use

reinforced insulation or double

insulation for the DC power supplies to
be connected to the DC I/O Units for CV500-PS211. Use separate power
supplies

as the external power supplies for the Relay Output Units and the

power supplies for the DC I/O Units.

3. To

meet the EC Directives (Low V

oltage Directive), the maximum switching

capacity while the CV500-PS211 is being operated is 24 VDC/2 A.

6Conformance to EC Directives

xv

4. PCs

complying with EC Directives also conform to the Common Emission

Standard

(EN50081-2). When a PC is built

into a machine, however

, noise
can be generated by switching devices using relay outputs and cause the
overall machine to fail to meet the Standards. If this occurs, surge killers
must be connected or other measures taken external to the PC.

The following methods represent typical methods for reducing noise, and
may not be sufficient in all cases. Required countermeasures will vary
depending

on the devices connected to the

control panel, wiring, the config

-

uration of the system, and other conditions.

Countermeasures

Refer to EN50081-2 for more details.
Countermeasures are not required if the frequency of load switching for the

whole system including the PC is less than 5 times per minute.
Countermeasures

are required if the frequency of load switching for the whole

system including the PC is 5 or more times per minute.

Countermeasure Examples

When

switching an inductive load, connect a surge protector

, diodes, etc., in par

-

allel with the load or contact as shown below.

Circuit Current Characteristic Required element

AC DC

CR method

Power
supply

Inductive

load

Yes Yes If the load is a relay or solenoid, there

is a time lag between the moment the
circuit is opened and the moment the
load is reset.

If the supply voltage is 24 or 48 V,
insert the surge protector in parallel
with the load. If the supply voltage is
100 to 200 V, insert the surge
protector between the contacts.

The capacitance of the capacitor must
be 1 to 0.5

µF per contact current of

1

A and resistance of the resistor must

be 0.5 to 1

Ω per contact voltage of
1 V. These values, however, vary with
the load and the characteristics of the
relay. Decide these values from
testing, and take into consideration
that the capacitance suppresses spark
discharge when the contacts are
separated and the resistance limits
the current that flows into the load
when the circuit is closed again.

The dielectric strength of the capacitor
must be 200 to 300 V. If the circuit is
an AC circuit, use a capacitor with no
polarity.

Diode method

Power
supply

Inductive

load

No Yes The diode connected in parallel with

the load changes energy accumulated
by the coil into a current, which then
flows into the coil so that the current
will be converted into Joule heat by
the resistance of the inductive load.

This time lag, between the moment
the circuit is opened and the moment
the load is reset, caused by this
method is longer than that caused by
the CR method.

The reversed dielectric strength value
of the diode must be at least 10 times
as large as the circuit voltage value.
The forward current of the diode must
be the same as or larger than the load
current.

The reversed dielectric strength value
of the diode may be two to three times
larger than the supply voltage if the
surge protector is applied to electronic
circuits with low circuit voltages.

Varistor method

Power
supply

Inductive

load

Yes Yes The varistor method prevents the

imposition of high voltage between the
contacts by using the constant voltage
characteristic of the varistor. There is
time lag between the moment the
circuit is opened and the moment the
load is reset.

If the supply voltage is 24 or 48 V,
insert the varistor in parallel with the
load. If the supply voltage is 100 to
200 V, insert the varistor between the
contacts.

1-1 Control Systems

A

Control

System is the electronic equipment needed to control a particular pro

-

cess.

It may include everything from a process control computer

, to the factory

computer,

down through the PCs, and then on down through the network to the

I/O

devices: control components like the switches, stepping motors,

solenoids,

and sensors which monitor and control mechanical operations.

I/O devices

A

Control System can involve very large applications where many dif

ferent mod

-

els

of PC are networked together or it could be an application as small as a single

PC controlling a number of output devices.

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 con

-

nected

to other PCs or to a host computer in order to integrate the control of a

complex process.

The Role of the PC Section 1-2

3

1-2-1 Input Devices

PCs

can receive inputs from either automated or

manual devices. The PC could

receive

data from the user via a pushbutton

switch, keyboard, or similar device.

Automated

inputs could come

from a variety of devices: micro-switches, timers,

encoders,

photoelectric sensors, 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 sensor and proximity sensor shown

below,

use other means, such as light or inductance, in order to get information

about the equipment being monitored.

Photoelectric

Sensor

Limit Switch

Proximity Sensor

1-2-2 Output Devices

A

PC can output to a myriad of devices for use in automated control. Almost

any

-

thing

that you can think of could be controlled by a PC. Some of the most com

­mon 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,

af

fect

the

controlled system directly

. Others, such as the indicator lights, buzzers, and

alarms,

provide outputs to notify personnel operating or monitoring the system.

Servomotor

Stepping Motor

The Role of the PC Section 1-2

1-3 PC Operation

PCs operate by monitoring input signals and providing output signals. When
changes are detected in input signals, the PC reacts through the user-pro­grammed

internal

logic to produce output signals. The PC continually executes

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.

Execution Cycle When a PC operates, i.e., when it executes its program to control an external

system, a series of operations are performed inside the PC. These internal oper

­ations can be broadly classified into the following four categories. Refer to the

CV-series PCs Operation Manual: Ladder Diagrams

for details.

1, 2, 3...

1. Common

(or overseeing) processes, such as watchdog timer operation and

testing the program memory.

2. Data input and output.

3. Program 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.
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?

PC Operation Section 1-3

5

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. Refer to the

CV

-series PCs Opera

­tion

Manual: Ladder Diagrams

for details on internal PC processing and to

the

CVSS Operation Manuals

for details on monitoring the cycle time.

duced

in this section. Refer

to the operation manuals for the Systems for details.

The

SYSMAC NET Link System is

a LAN (local area network) for use in factory

automation

systems. The SYSMAC NET Link System can consist of up to 128
nodes among which communications may be accomplished via datagrams,
data transfers, or automatic data links.

Datagrams

transmit and receive data using a

command/response format. Com

­mands can be issued from the user program by the DELIVER COMMAND in­struction (CMND(194)).

Data can also be transmitted and received using the NETWORK SEND and
NETWORK RECEIVE (SEND(192)/RECV(193)) instructions in the user pro­gram. Up to 256 words of data can be transferred for each instruction.

Automatic data links allow PCs and computers to create common data areas.

1-9-1 Upgraded Specifications

The following improvements are applicable to all CV500-CPU01-E and
CV1000-CPU01-E CPUs with lot numbers in which the rightmost digit is 3
(jjj3) or higher.

1, 2, 3...

1. The MLPX(110) (4-TO-16 DECODER) instruction has been improved to
also

function as a 8-to-256 decoder and the DMPX(111) (16-T

O-4 ENCOD

-

ER)

instruction has been improved to also function as a 256-to-8 encoder

.

To

enable this improvement, the digit designator

(Di) has been changed as

shown below.

3. The

operation of Completion Flags for timers has been changed so that the
Completion Flag for a timer turns ON only when the timer instruction is
executed

with a PV of 0000

and not when the timer’s PV is refreshed to a PV

value of 0000, as was previously done.
Only

the timing of the activation of the Completion Flag

has been changed,

and

the

timer’s PV is still refreshed at the same times (i.e., when the timer
instruction is executed, at the end of user program execution, and every
80 ms if the cycle time exceeds 80 ms).

4. The

READ(190) (I/O READ) and WRIT(191) (I/O WRITE) instructions have
been improved so that they can be used for Special I/O Units on Slave
Racks under the following conditions.

a) The

lot number of the Remote I/O Master Unit and Remote I/O Slave Unit

must be the same as or latter than the following.

1992
October (Y

: November; Z: December)

1st

01 X 2

b) The DIP switch on the Remote I/O Slave Unit must be set to “54MH.”
c) The Special I/O Unit must be one of the following: AD101, CT012,

CT021,

CT041, ASC04, IDS01-V1, IDS02, IDS21, IDS22, or LDP01-V1.

(The

NC221-E, NC222, CP131, and FZ001 cannot be mounted to Slave

Racks.)

1-9-2 Version-1 CPUs

CV-series CPUs were changed to version 1 from December 1993. The new
model numbers are as follows: CVM1-CPU01-EV1, CVM1-CPU11-EV1,
CV500-CPU-EV1, CV1000-CPU-EV1, and CV2000-CPU-EV1. (Of these, all
CVM1

CPUs were changed to version 2 from December 1994; refer to the next

sections for details.)
The following additions and improvements were made to create the version-1

CPUs.

PT Link Function The

host

link interface on the CPU can be used to connect directly to Program

-

mable Terminals (PT

s) to create high-speed data links. T

o use the PT links,

turn

ON

pin 3 of the DIP switch on the CPU. Pin 3 must be turned OFF for host link

connections.

EEPROM Writes With

the new CPUs, you can write to EEPROM Memory Cards mounted to the

CPU

by using the file write operation from a

Peripheral Device. A Memory Card

Writer

is no longer required for this write operation. W

riting is possible in PRO

-

GRAM mode only.

New Command A

new I/O REGISTER command (QQ) has been added so that words from dif

fer-

ent data areas can be read at the same time.

Faster Host Links The

communications response time for the built-in host link interface

on the CPU

has been improved by a factor of approximately 1.2.

Faster Searches The search speed from Peripheral Devices for instructions and operands has

been nearly doubled.

1-9-3 Version-2 CVM1 PCs

CVM1 CPUs were changed to version 2 and a new CPU was added from De­cember 1994. The new model numbers are as follows: CVM1-CPU01-EV2,
CVM1-CPU11-EV2, and CVM1-CPU21-EV2.

Improved Specifications Section 1-9

The following additions and improvements were made to create the version-2
CPUs.

CMP/CMPL New versions of the CMP(020) and CMPL(021) have been added that are not

intermediate

instructions. The new instructions are CMP(028) and CMPL(029)

and

are programs as right-hand (final) instructions. A total of 24 other new com

-

parison

instructions have also been

added with symbol mnemonics (e.g., >, +,

and <).

XFER(040) This instruction has been upgraded so that source and destination areas can

overlap.

DMPX(111) This instruction has been upgraded so that either the MSB or the LSB can be

specified

for use as the end code. Previously only the

the MSB could be used.

New Flags Underflow and Overflow Flags have been added at A50009 and A50010, re-

spectively.

These flags can be turned ON or OFF when executing ADB, ADBL,

SBB, and SBBL and can be saved or loaded using CCL and CCS.

New Instructions A total of 125 new instructions have been added. These instructions are sup-

ported by version-2 CPUs only.

Faster Online Editing The

time that operation is stopped for online editing has been reduced and is no

longer added to the cycle time. The following are just a couple of examples.

Edit Time operation is stopped

Adding or deleting one instruction block at the
beginning of a 62K-word program

Approx. 0.5 s

Deleting an instruction block containing JME
from the beginning of a 62K-word program

Approx. 2.0 s

The

above speed increase

also applies to all V1 CPUs with lot numbers in which

the rightmost digit is 5 (jjj5) or higher.

New Host Link Commands New

C-mode

commands for the CPU Host Interface have been added and the

functionality of existing commands has been improved as follows:

New Commands

• RL/WL: Read and write commands for the CIO Area.

• RH/WH: Read and write commands for the CIO Area.

• CR: Read command for the DM Area.

• R#/R$/R%: SV read commands.

• W#/W$/W%: SV change commands.

• *: Initialization command.

Improved Commands

• The Link Area (CIO 1000 to CIO 1063) and Holding Area (CIO 1200 to
CIO 1299) can now be specified for the KS, KR, KC, and QQ commands.

• CVM1-CPU21-EV2 can now be read for the MM command.

The above new and improved commands can also be used with all V1 CPUs
with lot numbers in which the rightmost digit is 5 (jjj5) or higher.

Note Only the following Programming Devices support version-2 CPUs: SSS

(C500-ZL3AT1-E) and the CVM1-PRS21-EV1 Programming Console
(CVM1-MP201-V1).

Of these, the SSS does not support SFC

and thus cannot

be used for the CV500, CV1000, and CV2000. Use the CVSS for these PCs.

2-1 System Configuration

This

section provides illustrations of CV

-series PC Systems, which can be clas

-

sified into five different types of configuration.

• Systems with only a CPU Rack

• Systems with only CV-series Expansion I/O Racks.

• Systems with an Expansion CPU Rack.

• Systems with a Single CV-series Expansion I/O Rack.

• Systems with C500 Expansion I/O Racks.

If

only a CPU Rack is used, an I/O Control Unit is not required, but the CPU Rack
is otherwise the same as those in the following examples. The specific Units
used in the configuration are described in more detail later.

The maximum I/O capacity with any configuration is 512 points (32 words) for
the CV500 or CVM1-CPU01-EV2; 1,024 points (64 words) for the CV1000 or
CVM1-CPU11-EV2; and 2,048 points (128 words) for the CV2000 or
CVM1-CPU21-EV2.

The I/O capacity will be less depending on the Racks and

the types of Units mounted.
The

following figure shows an assembled CV

-series CPU Rack and seven Ex

pansion

I/O Racks. Up to seven Expansion I/O Racks may be connected in one

or

two series from the CPU Rack. The total length of I/O Connecting Cable must

be

50 m or less for each series and a T

ermination Resistance Unit must be be

connected to the last Rack or to the unused I/O Control Unit connector.
Units can be mounted to any slot on the Racks shown for them below.

When nine or more CPU Bus Units (Temperature Controller Data Link Units,
SYSMAC

NET Link Units, SYSMAC LINK Units, SYSMAC BUS/2 Remote I/O

Master Units, Ethernet Units,

BASIC Units, and Personal Computer Units) are

required

in a System, the CPU Rack may be extended by connecting an Expan

-

sion CPU Rack to enable mounting up to 16 CPU Bus Units.
Only

one Expansion CPU Rack may be connected to a CPU Rack. A system that

includes

an Expansion CPU Rack can be extended by connecting up to six Ex

-

pansion

I/O Racks.

The Expansion I/O Racks may be connected in one or two
series from the CPU Rack. The total length of I/O Connecting Cable must be
50 m or less for each series and a Termination Resistance Unit must be con­nected to the last Rack or to the unused I/O Control Unit connector.

Using

an Expansion CPU Rack does not increase the maximum

I/O capacity of

the PC; it only increases the number of CPU Bus Units that can be used.
Units can be mounted to any slot on the Racks shown for them below.
