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.
