Figure 10.2 – Alpha-numeric Keypad
Once the desired value is entered, 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.
