These blue keys include numbers, letters, and symbols used for addresses,
password, file numbers, and other data. The data you enter always appears
on the prompt/data entry/error message area of the display.
In general, you obtain the upper character of a key by pressing the
[SHIFT]
key first. You do not have to hold it and press next key. Just press and
release
[SHIFT]
and then press the next key.
If you make an error while entering data, press
[ESC]
and re–enter the data,
or use cursor keys and the space key. To complete a data entry, press
[ENTER]
. You can also use the
[ESC]
key to exit the data entry and return to
the next higher (previous) menu level.

SHIFT mode. This mode is indicated by a small arrow in the bottom right
hand corner of the display.

Cursor Keys

Use these four green, arrow keys to:
•
Correct data entry errors (either type over or use space key).

Move the cursor left, right, up, and down in a ladder program. Rungs not
shown in the HHT display will automatically scroll into view as you
cursor down (or up) in the program.
•
Scroll through controller and I/O configuration selections.
•
Scroll through program file directories.
•
Scroll through the elements and bits of individual data files.
ZOOM and RUNG Keys
The
[ZOOM]
key brings up a display that shows the parameters of an
instruction (helpful with timers, counters, sequencers, etc.; also helpful
during editing).
The
[RUNG]
key moves the cursor to a particular rung. Using the
[RUNG]

[RUNG]

you are prompted for the rung number that you want to edit or monitor. You
enter the rung number and press
[ENTER]
, then the cursor moves to the
selected rung and the rung appears at the top of the screen.
