Figure 11.2: Alpha-numeric Keypad
Once the desired value is entered, pressing the Enter key moves that value into the object (and the
corresponding OCS register) and the alpha-numeric keypad disappears. Alternately, pressing the ESC
key any time before the Enter key cancels the operation, leaves the objects current value unchanged, and
the alpha-numeric keypad disappears.
Note: Each numeric entry object has a configured minimum and maximum value. If the operator enters a
value outside of the configured range, the new value is ignored when Enter is pressed and the current
object value is NOT changed.
Since the alpha-numeric keypad services several different graphical objects, certain keys on the alpha-
numeric keypad may be disabled (grayed) when the keypad is invoked for certain objects. The following
describes the alpha-numeric keypad variation based on object.
Numeric Object
When editing a numeric value, the [+/-] or the [.] key are disabled (grayed) if the object is NOT configured
for floating-point value or a signed value.
Password Object
When editing a password value, the arrow keys, [+/-], and the [.] keys are disabled. Additionally,
overwrite mode is disabled. When entering digits, the pop-up keypad hides the value by displaying ‘*’
alternately for each digit.
ASCII Object
When editing an ASCII value, each press of the same key generates a different value. For example, the
[1 _QZ] key generates the following sequence:
, Q, Z, q, z, 1,
The digit keys (except zero) sequence the corresponding 3 alphabetical characters first in upper case
followed by the same 3 characters in lower case followed by the corresponding numeric digit. Thereafter,
continued presses of the same key repeat the sequence.
