Figure 13.2 – Alpha-numeric Keypad and ASCII 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, an ASCII keypad is displayed as shown figure 13.2. The ASCII keypad has
3 modes, numeric, symbols and alpha. In Alpha mode the Caps Lock button may be pressed to access
capitol letters. When you first enter this editor typing a character will overwite the entire old string and
start a new entry. You may press the back space arrow to delete the previous character. Pressing Enter
will save the entry, pressing ESC will cancel the edit and return the string to the previous value.
Text Table Object
When editing a Text Table Object, all the keys except the Up and Down arrow keys are grayed and
disabled. The next text selection is made by pressing either the Up or Down arrow.
