Note: The built-in display may show the error message "Error 40" blinking the very
first time you turn on the power supply to the Visual KV Series. Press any key
around the display to cancel this message.
The Visual KV Series shows this message when no program is loaded.

Note to User

When using the Visual KV Series in the following conditions or environments, be
sure to use the Visual KV Series with sufficient margin regarding the rating and
functions, take appropriate safety precautions such as fail-safe, and contact our
sales personnel if any questions arise.

• Use in conditions or environments not described in this manual

• Use for nuclear power control, railway facilities, air service facilities, vehicles,
combustion devices, medical equipment, amusement machines, safety equip­ment, etc.

• Use for applications where large effects are predicted to be given on human lives
and properties and safety is especially requested.

Restriction on Acquiring the CE Marking

■ Restriction to be compatible with EMC directives

• When using a relay output type unit (whose model name ends with "R"), connect
spark killers having the appropriate withstand voltage against the load to the
output terminals in parallel to contacts (because the unit discharges when a relay
contact becomes open and noise is generated). In our experiments, we use the
following models of spark killers.

XEB0101 0.1 µF-10 Ω manufactured by OKAYA DENKI SANGYO
The following 1-turn ferrite core is added to the AC power input circuit of the KV-

40AR/T, the KV-24AR/T and to the DC power input circuit of the KV-40DR/T.
ZCAT3035-1330 manufactured by TDK

Note: The contents above do not by themselves ensure that the entire machine
manufactured in accordance with the above contents is compatible with EMC
directives.

You must judge by yourself whether or not the entire machine is compatible with
EMC directives because compatibility may change depending on the component
configuration, wiring and location inside of the machine.

■ Restriction on compatibility with low-voltage directives (IEC-1010-1)

• Use insulated type crimp-style terminals.

• For wiring materials, use lead wires whose sheath is 0.4 mm or more.

• The Visual KV Series is allowed to be installed in a vertical position only.
(Spacers for expansion units are not available.)

• Be sure to use the Visual KV Series inside the control panel.

Features of the Visual KV Series

● Extremely small

The Visual KV Series is the smallest in the world among AC type PLCs equipped
with screw terminal blocks, and saves installation space.

● Extremely fast

The minimum scan time is 140 µs and minimum instruction execution time is 0.7
µs, which is the fastest control in its class.

● AC power built-in type newly added

AC power built-in type units are newly added. This type can be used in small
spaces where a switching power supply unit cannot be installed.

● Excellent Access Window

An Access Window with two-color backlight is adopted in all models to facilitate
changing and monitoring of device data. Changing between RUN mode and
PROGRAM mode, checking the error code when an error has occurred, etc. can
be performed in a Visual KV Series unit without the need for any handheld
programmer.
The analog trimmer, which has been popular in the conventional KV Series, is
digitized to enable more detail settings. [Digital trimmers]

● User message setting function

In the Access Window, 256 different user messages can be displayed. This
function can be used to give instructions on works on the production line, indicate
abnormalities in the units, etc.

● Program write in RUN mode

Ladder programs can be changed even while the system is running.

● Equipped with two serial ports

Visual KV Series basic units are equipped with two serial ports to connect periph­eral units, improving the debug environment.
(The KV-10xx is equipped with only one serial port.)

● Easy Ramp-up/down control function

The one-axis motor control function is offered separately from high-speed
counters so that feedback control is enabled.

● Equipped with two 24-bit high-speed 30 kHz, two-phase counters

The Visual KV Series is equipped with two high-speed counters each with a two­point comparator output function that enables high-speed encoder input.

● Specified frequency pulse output function

High-speed counters can function as pulse oscillators of 50 kHz maximum with
easy setting, without creating a complicated ladder program.

● Frequency counter function

High-speed counters can function as frequency counters with easy setting,
without creating complicated ladder programs.

● Cam switch function

High-speed counters can function as cam switches with easy setting, without
creating complicated ladder programs.

(3)

● Interrupt function

The Visual KV Series is equipped with four high-speed interrupt inputs of
10 µs maximum.

● Input time constant change function

The time constant can be set in 7 steps from 10 µs to 10 ms.

● Double memory backup functions

In addition to a conventional SRAM battery backup function, the Visual KV Series
is also equipped with an EEPROM backup function.

Compatibility with Conventional KV Series Peripheral Units

The Visual KV Series functions as a high-end compatible model of the conventional
KV Series. Peripheral units of the conventional KV Series such as the ladder support
software "KV IncrediWare (DOS)" and "LADDER BUILDER for KV" and the
handheld programmer KV-P3E(01) can be used since they are part of the Visual KV
Series.
However, it should be noted that the contents have changed as follows.

• The internal clock cycle of high-speed counters consists of three types: 1 µs, 10
µs, and 100 µs.

• The time constant for an input relay specified by the HSP instruction is 10 µs.

• The analog trimmer function is set with the Access Window built into the basic
unit.

• The available device setting range of the TMIN instruction is from 0 to 65535.
[Handheld programmer KV-P3E(01) can display 0 to 9999 .]

• The RUN/PROGRAM LED is displayed in the Access Window provided on the
front face of the basic unit.

• Transistor output is not independent, but is common.

• With the transistor type, the output terminal layout is different.

• The specifications for output current of transistor outputs Nos. 500 to 502 is 100
mA.

• Conventional KV Series expansion units are not available as expansion units for
the Visual KV Series.

• The channel setting switch is not provided for expansion units. Channels are
determined in connection order.

• Scans in expansion I/O units are not synchronous with the scan time in Visual KV
Series basic units.

• Assignment of special utility relays has partially changed.

• Data memory device Nos. DM1000 to DM1999 are assigned as special data
memories.

(4)

Cautions when using the previous version of ladder support software

Pay strict attention to the following items when using the ladder support software.

• When using the ladder support software "KV IncrediWare (DOS)" or "LADDER
BUILDER for KV Ver. 1.0x", set the model to "KV-300".

• DM0 to DM1999 are only available.

CAUTION

When the ladder support software "LADDER BUILDER for KV Ver. 1.0x" is
used, do not use the monitor’s Change All function. If the Change All function
is used, the basic unit may be damaged. Never use the Change All function.

Peripheral units and other units incompatible with the Visual KV Series

Peripheral units in the conventional KV Series and other units shown below are not
compatible with the Visual KV Series.

• Expansion I/O units for the conventional KV Series: KV-8ER/8ET/8EX/16EX/
8EYR/8EYT/16EYR/16EYT

• Analog I/O units for the conventional KV Series: KV-AD4/DA4

Cautions when Using the Serial Port

The KV-16xx/24xx/40xx units are equipped with two RJ-11 modular connectors for
serial communication.
When using them, pay strict attention to the following contents:

• Programs can be transferred and monitored using either communication port A or
B. However, never connect the ladder software and a handheld programmer to
the two ports at the same time.

• The KV-D20 operator interface panel can be connected to either communication
port A or B. However, only one KV-D20 unit can be connected to a single basic
unit.

• Never leave both the KV-D20 operator interface panel and KV-P3E(01) handheld
programmer on simultaneously for a long period of time.

(5)

Cautions when writing in RUN mode

WARNING

• In the Visual KV Series, a program can be changed using the ladder sup­port software "LADDER BUILDER for KV" even while the program is run­ning.

• Pay strict attention to safety when performing any writes in RUN mode.

• The situation may become extremely dangerous depending on the status of
the controller device connected to the PLC or the program used.

When writing in RUN mode, each function is offered as follows:

Note 1: When a ladder program is changed while it is running, it is not saved in the
EEPROM but is saved in the SRAM, then will be saved in the EEPROM when the
power is next turned on. If the power OFF period is 2 months or longer at 25°C (20
days or longer at 25°C for the KV-10xx) after a ladder program is changed in RUN
mode, the changed ladder program may become corrupted. To prevent inconsisten­cies, turn on the power once so that the changed program is saved in the EEPROM.

Note 2: If an error occurs in the Visual KV Series basic unit while a program is being
written in RUN mode, the Visual KV Series basic unit changes to PROGRAM mode
and the existing program which is being written may be deleted. In such a case,
transfer the program again.

Chapter 1 Introduction

1.2.2 Features and functions of the Ladder Builder for KV

The Ladder Builder for KV is a software program that allows you to create sequence
programs. It offers excellent functionality and advanced programming processing
ability.

Features of the Ladder Builder for KV

1

■ The multi-file edit function and simple mouse operation improve work
efficiency.

Because two or more files can be edited at a time, a block diagram can be cut
and pasted between files. Symbols and connection lines can be easily copied
and moved using the mouse. Each function can be started by pressing a button
on the tool bar, which promotes efficient operation.

■ Selection of instruction words and devices from a list ensures the correct
input of symbols.

Because the instruction word and device can be selected from a list for each
type, symbols can be entered with little error. A symbol can also be entered
directly by typing the corresponding instruction word to facilitate rapid program­ming.

2-4

■ Ladder data can be shared with the KV IncrediWare (DOS).

Because the ladder data created using the KV IncrediWare (DOS) can be used
as it is, the ladder property created thus far can still be used effectively. The
ladder data created using the Ladder Builder for KV can also be used in the KV
IncrediWare (DOS).

Chapter 1 Introduction

■ Allows quick selection of the device to be monitored by dragging and
dropping from the ladder diagram.

The device to be monitored can be easily and quickly selected by dragging and
dropping it from the ladder diagram.

■ Allows quick confirmation of the ladder diagram, the contacts and the
timing chart.

Each of the three windows can be positioned anywhere on the screen, allowing
you to simultaneously monitor and simulate the operation of the program. The
three windows are the Ladder Monitor window which displays the ladder dia­gram, the Monitor All window which displays the device list, and the Registration
Monitor window which allows you to check the movement of the contacts in the
timing chart.

1

■ Allows use of the simulator functions even when not connected to a PLC.

You can monitor and simulate the operation of the program even when a PLC is
not connected. Debugging efficiency is improved because program operation can
be checked without transferring the program to the PLC. As well, the reverse
step execution function is provided both for execution of scans and execution of
steps.

■ Provides 5 different screen sizes for different applications.

There are 5 different screen display sizes that can be selected as required for
different applications. For example, the reduced size can be selected to confirm
the entire flow, and the enlarged size can be selected to edit each contact.

Chapter 1 Introduction

Functions of the Ladder Builder for KV

The following functions are provided in the Ladder Builder for KV.

■ Editor function

• Creates the ladder diagram using diversified instruction words of the ladder
language.

• Registers comments to contacts. Comments can be transferred to a Visual KV or

1

a KV-300 (Except for KV-10/80 Series).

• Converts the ladder diagram into machine code.

• Displays the ladder diagram, mnemonic list, label comment and device use
status list, etc., on the screen and prints them out to the printer

■ Simulator function

• Simulates the operation of the ladder diagram even if a Visual KV or a conven­tional KV is not connected, and allows debugging of the program.

• Provides a continuous scan execution mode, one scan execution mode, one step
execution mode, etc. so that errors be confidently located.

• Enables execution of a step in the reverse direction once or continuously.

2-6

■ Monitor function

• Monitors the contact ON/OFF status on a real-time, on-line basis using the ladder
diagram created.

• Displays the timing chart, and transfers programs to a Visual KV or a conven­tional KV.

1.3 Before Programming

The personal computer should be connected to a Visual KV or a conventional KV to
transfer the programs to the Visual KV or the conventional KV and to use the moni­tor function.

Machines to be prepared

You must prepare the following machines before beginning programming.

1.5 Cautions for Use

This section describes the cautions for using the Ladder Builder for KV. Be sure to
read this section.

■ When a notebook personal computer is used

When a notebook personal computer is used, ensure that the RS-232C is set up. If it
is not, a communication error will occur while the monitor is operating and monitor
operation may not be correct.
For the setup procedure, refer to your personal computer’s instruction manual.

■ While the monitor is operating

Never turn off the power of the Visual KV, the conventional KV or unplug the con­nection cable while the monitor is operating. This may cause a communication error
to occur and the monitor to be forcibly terminated.

■ Monitor after the ladder diagram is changed

Be sure to select "Convert ➞ Transfer ➞ Monitor" from the menu and transfer
programs to the PLC when operating the monitor after changing the ladder diagram.

■ Resolution of the screen

Ensure that the resolution of the screen is at least 640 x 480. It is recommended that
the highest possible resolution be used to ensure comfortable operation. (1,024 x
768 or higher is recommended.)

■ Long file names

The Ladder Builder for KV runs in Windows 95, but it does not support long file
names. File names can only consist of up to 8 half-width characters and the file
extension (3 characters).

1.6 Basic Operations

This section describes what you should know before using the Ladder Builder for
KV, such as the programming flow, available modes, software startup procedure,
and software termination procedure.

1.6.1 Program creation flow and available modes

Three modes are available in the Ladder Builder for KV. These are the editor,
monitor and simulator modes. The actual programming procedure, the modes used
in each procedure and the major functions available in each mode are described
below.

1. Creating the ladder diagram

Create the ladder diagram based on the design drawing indicating the operations to
be performed by the PLC.

3. Debugging the program

Read the machine code created by the editor, and confirm the operation status
including changes in devices. This allows errors to be detected and the ladder
program to be changed accordingly.

• You can use either the simulator or the monitor when debugging the program.
When using the simulator, you can simulate the status in which a Visual KV or a
conventional KV is connected. When using the monitor, you actually connect a
Visual KV or a conventional KV and write programs to it.

• The method for using the ladder monitor, the monitor all and registration monitor
which indicate the device status; the method for setting up the current value/
preset value/attribute from the dialog bar; and the method for printing out the
registration monitor are shared between the simulator and the monitor with the
exception of certain functions. These methods are described in the simulator
section.

When a CPU unit is not connected: Simulator

• Set the break condition, the wait time, the scan time, etc.

• Execute scan continuously or once.

• Executes a step continuously, a step continuously in the reverse direction, a step
once or a step once in the reverse direction.

• Change the timing chart size.

• Display the mnemonic list.

• Search for devices.

When a CPU unit is connected: Monitor

• Serial port setting

• Start and stop the monitor, and reconstruct the record.

• Set up the PLC mode.

• Disable input refresh, disable output (Visual KV Series and KV-300)

• Transfer programs (When the menu is selected from the editor and executed,
programs are transferred to the monitor.)

• Search for devices.

2.1 Outline of the Editor Functions

This section outlines each function available in the editor. For detailed descriptions
of each function, refer to the corresponding page.

The editor allows you to create ladder diagrams, and provides editing functions
including input of instruction words and registration of comments.

The editor offers the following functions.

2

2.1.1 Cautions for editing ladder programs

• Creates ladder diagrams using diversified instructions of the ladder language.

• Performs editing functions including copy and move.

• Registers a comment for a contact and transfers it to the Visual KV or the con­ventional KV.

• Converts ladder diagrams, and transfers the converted diagrams to a PLC.

• Prints out ladder diagrams, mnemonic lists, label comments, device status lists,
etc.

The maximum number of editable lines is 9,999.

The maximum number of lines that can be edited for one ladder program window by
the Ladder Builder for KV is 9,999. The maximum size of one block is 100 lines.
Keep in mind that a ladder program exceeding 9,999 lines cannot be created.

When the program is running slowly

When many applications are simultaneously running on a personal computer with
low memory capacity, the memory and the source become insufficient. As a result,
the swap file is frequently accessed and operating speed deteriorates. If this occurs,
close other applications to decrease the load on the system.
It is also effective to increase the memory.

4. Under the macro start declaration line, enter the symbol to be processed by the
macro. At this time, describe the devices to be treated as arguments as tempo­rary devices.

What are temporary devices?

Temporary devices indicate devices described temporarily when actual devices
are not yet determined. Up to 1,000 temporary devices from "@0" to "@999" can
be described. Each temporary device will be automatically replaced while a
macro is developed.

Note: Up to 10 devices from "@0" to "@9" can be used in each macro. When using
them, make sure to assign temporary devices sequentially starting from "@0".

5. In the last line, enter two "@" symbols from "Edit Line Comment" as the macro
end declaration line.

Example
