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.
