Manual

2. Overview and Operation

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 dis-

played. 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 at-

tribute 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 KV-

D20 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.

Error messages

The following table shows the error messages that may appear during the display

setting of DM1580 through DM1599.

* For other devices, their values are displayed even if they are not used.
