Chapter 2. OUTLINE OF FUNCTIONS
• If the character string cannot be changed using the [ ] key while the
entire character string is flashing, press the [ ] key.
On the contrary, if the character string cannot be changed using the
[
] key, press the [ ] key .
• When pressing the [para] key while the display is flashing, the next
data is displayed without changing of the data. Additionally, when
pressing the [mode] key while the display is flashing, the display is
returned to the operation display without changing of the data.
• The MV (manipulated variable) display in the MANUAL mode
continues the flashing status even after pressing of the key has been
stopped. At this time, the flashing value is output as MV.
■ [mode] key operating procedures
When the [mode] key is kept pressed for 1 sec. or longer on the operation display,
the selection operation, which has been set using the [mode] key function (C72) of
the setup setting, can be performed.
The Figure on the right shows an example that the
[mode] key is pressed in the RUN/READY selection
(C72 = 2) setting.
(1) If the current mode is the READY mode when the
PV/SP is shown on the operation display, the
character string "rUn" on the display No. 2 starts
flashing.
(2) When the [mode] key is kept pressed for 1 sec. or
longer, the READY mode is changed to the RUN
mode and the flashing of the character string "rUn"
is stopped.
(3) When pressing of the [mode] key is stopped, the
display is returned to the PV/SP display.
Handling Precautions
• If the MODE key function of the setup setting is set disabled (C72 = 0)
or if the set selection operation is invalid, the selection operation
cannot be performed using the [mode] key.
• When pressing the [mode] key on the parameter setting display or
setup setting display instead of the operation display, the display is
returned to the operation display. However, even though the [mode]
key is kept pressed continually, the selection operation cannot be
performed. In this case, stop pressing the key once, and then press
the [mode] key.
