2. Overview and Operation

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