The KV-D20 may cause malfunctions due to loose modular cable connectors or mounting fixtures during long-term use. Be sure to regularly check the KV-D20 unit and connections. The major items to check are as follows:

Maintenance

CAUTION

• Are the modular cable connectors disconnected or loosened?

• Are the mounting fixtures of the KV-D20 detached or loosened?

Dust adheres to the KV-D20 during long-term use. Wipe the dust off using a clean dry cloth. If dust or dirt adheres to a small part, wipe it off using a cotton swab.

Be sure to turn off the KV-D20 before inspection or maintenance.

Page 15

2. Overview and Operation

2.1 Use Examples for the KV-D20

This section includes examples of uses for the KV-D20.

As a handheld programmer

The KV-D20 allows you to change the KV series’ operating mode (RUN or PROGRAM) or to change the preset values of timers and counters without using the KV-P3E(01) handheld programmer.

As a digital switch

Various values can be input with the KV-D20. You can directly change the values of desired devices without using ladder programs. Moreover, the KV-D20 can be connected with a cable instead of the I/O unit, so that the amount of wiring and I/O points can both be reduced.

As a display unit

The KV-D20 can display the number of products or the tact time. Since the KV-D20 can be connected with a cable instead of the I/O unit, the amount of wiring and I/O points can both be reduced.

As a device to give instructions to workers

When using a rotating beacon, the occurrence of an error can be noted but the contents of the error, such as a clogged workpiece, missing workpiece, or product changeover, may often be unclear. The KV-D20 features a user message function. By using the function, work efficiency can be greatly improved. A beep function is also available to indicate errors with sound.

■ Decimal point position (Bits 0 to 3) [Initial setting: 0 (No decimal point)]

• Specify the number of digits to the right of the decimal point.

• The position of the decimal point can be set within the maximum number of digits to be displayed. The setting of a larger value is ignored.

Example

When the number of bits is set to 16 bits, the maximum number of digits is 5, so that the decimal point position can be set between 0 and 5. Values larger than 5 are regarded as 5.

• The decimal point is fixed at the specified position.

• Values between 0 through 15 can be used (4-bit binary).

• If a device has a preset value such as counters and timers, the decimal point is also set to the preset value at the same position as the current value.

• If a device has no numeric values to the left of the decimal point, "0." is displayed.

Example

When a decimal point position is specified at the third digit from the right, value "123" is displayed as "0.123".

2. Overview and Operation

■ Number of spaces to the right of a numeric value (Bit 4 to 7)

• Normally, numeric values are displayed from the right end. Setting the number of spaces to the right of a numeric value changes the position of the numeric value as desired.

Note: The position of the PRESET value cannot be changed.

• Values from 0 through 15 can be used (4-bit binary). However, the maximum number of spaces is the one at which the maximum value is left flush. The number of spaces is not increased even when a larger number is specified.

Example

When the device display is set to 16 bits with signs, the allowable number of spaces is obtained in the following equation:

• Carefully selecting the number of spaces to the right of a numeric value and the comment results in an easy-to-see display.

Example

"_" represents a space.

Comment: "DEFECTIVE:_ _ _ _ _ _ _ _PACKS" Number of spaces to the right of a numeric value: 5

Displayed comment: "DEFECTIVE:_ _ _ _ _123PACKS"

As shown above, the comment can be added at the end of the numeric value, improving visibility.

■ Show/hide numeric values (Bit 8)

Specify whether or not to display a numeric value on each line.

• To display only the comment on a line, turn on Bit 8.

• Even when Bit 8 is on, PRESET is displayed for devices using two lines (timers and counters). To hide the PRESET display, turn on Bit 12 (Show/hide preset value).

[Initial setting: 0 (No spaces on the right end)]

Sign

5 spaces

Number of digits of numeric value

Number of spaces is limited to 14 even when "15" is specified.

[Initial setting: Show comment and numeric value]

■ Show/hide signs (Bit 9) [Initial setting: Hide signs]

Specify whether or not to display signs for the displayed value.

• To display a minus sign, turn on Bit 9.

• The value is processed with two’s complement number and displayed with a negative sign.

Example

"#65535" is displayed as "-1".

•A negative sign is displayed to the left of the numeric value. (The sign shifts its position as the number of digits increases.)

Page 32

2. Overview and Operation

■ Number of bits (Bit 10) [Initial setting: 16 bits]

Specify the number of bits to be used to display the numeric value.

• To display a value with 32 bits, turn on Bit 10.

• The 32-bit display is available only for devices TM and DM.

• When 32-bit display is set, the specified device is displayed in low-order bits, and the device that has the next device number of the specified device is displayed in high-order bits.

• Devices CTC and CTH can be displayed with 24 bits, which is specified with the MEMSW instruction. (In this case, the Bit 10 setting is ignored.)

■ Notation (Bit 11) [Initial setting: Decimal]

Specify the notation used for the numeric value to be displayed.

• To select hexadecimal notation, turn on Bit 11.

• In the hexadecimal notation, "$" is prefixed to the numeric value and the zerosuppression function is disabled.

• If a device has a preset value such as timers and counters, the same notation is used for both the preset value and the current value.

• The initial setting for relay is turning on/off one bit. When Bit 11 is ON, the status of eight bits is displayed collectively. These eight bits cannot be turned on or off.

• When eight bits are displayed collectively, relays of eight bits starting from the specified relay are displayed.

Example

When relay 00502 is specified, the status of relays 00502 through 00509 is displayed from the right end.

Decimal display

Hexadecimal display

8-bit ON/OFF indication

■ Show/hide preset values (Bit 12) [Initial setting: Show preset values]

Specify whether or not to display a preset value when the device has a preset value such as timers and counters.

• To hide the preset value, turn on Bit 12.

■ Zero-suppression setting (Bit 13) [Initial setting: Use zero suppression]

Specify whether or not to use the zero-suppression function for the displayed preset value.

• To disable the zero-suppression function, turn on Bit 13.

■ Enable/disable changing preset values (Bit 14) [Initial setting: Enable]

If a device has a preset value such as timers and counters, specify whether or not to change the preset value with the KV-D20.

• To disable changes, turn on Bit 14.

■ Enable/disable changing (current) values (Bit 15) [Initial setting: Enable]

Specify whether or not to change the currently displayed value with the KV-D20.

• To disable changes, turn on Bit 15.

Page 33

Priority of attribute display (except for Bits 14 and 15)

1. Show/hide numeric value

2. Notation

3. Others

Note 1: When "Show/hide numeric value" is set to OFF (Bit 8 is ON), the numeric value is not displayed even if other bits are turned ON. Only comments are displayed. However, the display of the preset value for a device using two lines (timers and counters) depends on the Bit 12 setting.

Note 2: When "Notation" is set to "hexadecimal" (Bit 11 is ON), the decimal point, zero-suppression, and sign settings are ignored even if they are specified.

Cautions about the numeric value change mode

• Numeric values can be changed when the KV is in both RUN and PROGRAM modes.

• The KV-D20 automatically exits the numeric value change mode and returns to the normal mode when no keys are pressed for approximately 25 seconds. In such a case, the value being changed is canceled.

• Even if the zero-suppression function is specified in the normal mode, the function is canceled in the numeric value change mode. In such a case, some comments may be hidden by zeros.

•A line does not flash if it is set to disable the value change by the device attribute display setting. If all lines are set to disable the value change, no line flashes.

➮

Refer to "Device attribute display setting" on page 30.

• After values are changed, it takes "one scan + 100 ms" at maximum until the change is reflected.

• All contents of the displayed devices are not actually changed while the KV-D20 is in the numeric value change mode. The contents are updated after the KVD20 returns to the normal mode.

• Do not change the ladder program in the KV while the numeric value is changed with the KV-D20.

• Values outside of the available setting range cannot be entered.

2. Overview and Operation

2.5 Device Mode

Device mode

This section includes an overview and description of operation of the device mode.

This mode corresponds to the device mode of the Access Window of the KV unit. The device mode allows you to display all values of devices: data memory (DM), temporary memory (TM), timers (T), counters (C), high-speed counters (CTH), high-speed counter comparators (CTC), trimmers (TRM), and relays (RLY). (T, C, CTH, and CTC values can be displayed only when they are described in the ladder program). Moreover, you can change the values of all devices except for TRM and the relays set to 8-bit ON/OFF indication.

Data memory (Initial screen)

Temporary data memory

Timer

Counter

• Pressing the (This change switches relays between ON/OFF display and 8-bit ON/OFF indication. When the 8-bit ON/OFF indication is set, these eight bits cannot be turned ON or OFF.)

• When the 8-bit ON/OFF indication is set, the relay numbers 0 through 7 (8 through 15) are assigned from the right to left. When the 8-bit ON/OFF indication is reset to the ON/OFF display, the device that was displayed on the first line comes to the top of the screen.

Example

• In the hexadecimal notation, "$" is prefixed to the numeric value and the zerosuppression function is disabled.

• In the device mode, contact comments are not displayed but only device numbers are displayed.

• Devices of consecutive numbers are displayed on four lines.

• In the device mode, the attributes specified in DM1680 through DM1699 are not reflected.

• CTC and CTH can be changed to a 24-bit display with the MEMSW instruction. In this case, other devices remain at a 16-bit display.

key changes between decimal and hexadecimal notation.

High-speed counter comparator

Relay

Trimmer

(value cannot be changed)

Page 39

• To change from the operator mode to the device mode, special utility relay 2508 must be turned on. (The initial setting disables the change.)

• When changing to the current mode (screen) is disabled during operation, the setting becomes effective after the current mode (screen) is changed to another mode (screen). To activate the setting immediately, turn on special utility relay

2513. The mode is switched to the operator mode.

➮

Refer to "Screen change function" on page 22.

• When high-speed counter is specified, CTH0, CTC0, and CTC1, or CTH1, CTC2, and CTC3 are displayed on one screen.

• If a timer, counter, or high-speed counter that is not described in a ladder program is specified, "- - - - -" is displayed.

Precautions about numeric value change mode (when a device is flashing)

• Numeric values can be changed when the KV unit is in both RUN and PROGRAM modes.

• The KV-D20 automatically exits the numeric value change mode and returns to the normal mode when no keys are pressed for approximately 25 seconds.

• Even if the zero-suppression function is specified in the normal mode, the function is canceled in the numeric value change mode.

• After values are changed, it takes "one scan + 100 ms" at maximum until the change is reflected.

• All contents of the displayed devices are not actually changed while the KV-D20 is in the numeric value change mode. The contents are updated after the KVD20 returns to the normal mode.

• Do not change the ladder program in the KV while the numeric value is changed with the KV-D20.

• Values outside of the available setting range cannot be entered.

• The numeric value change mode is canceled when a user message is displayed during the change.

3.1 Basic Ladder Programs

This section describes basic ladder programs for actual use of the KV-D20.

Before creating ladder programs

Notes on contact comment display

When entering a contact comment, note the following:

• Enter a contact comment using alphanumeric characters.

• To enter a space to the left of a contact comment, input "~" (swung dash) at the left end of the comment with the LADDER BUILDER for KV. Spaces without "~" at the left end will be ignored. When "~" is used in the middle of a contact comment, it is displayed as "➞".

• Contact comments can be displayed only when the LADDER BUILDER for KV Ver. 1.5 or later is used and the compression transfer of contact comments is not selected.

• Even the contact comments for ladder programs created with LADDER BUILDER for KV Ver. 1.0x or KV-LADDER can be displayed on the KV-D20 after being transferred to the KV unit with the LADDER BUILDER for KV Ver.

1.5 or later.

• "Not transfer" is initially set as the contact comment transfer setting of the LADDER BUILDER for KV Ver. 1.5 or later. To display contact comments on the KV-D20, enable the contact comment transfer setting with the LADDER BUILDER for KV Ver. 1.5 or later.
