IMPORTANT: The Numeric Keypad Enable Buttons are retentive
objects. Your PanelView terminal will retain the current value of Numeric
Keypad Enable Buttons even after you’ve turned the terminal off, or
switched to Configuration mode. This is true for both the Keypad Control
Address and the Decimal Point Position Address. Presets can be defined
for both.
Small or Large Numeric Entry Keypads
(Touch Screen terminals only)
The Small or Large Numeric Entry Keypads enable an operator to send
numeric data to the PLC controller from a Touch Screen terminal.
The two keypads differ only in size: the large keypad is 48 characters wide;
the small keypad is only 24 characters wide. Both keypads are 24 lines
high, and both keypads operate in exactly the same way

Both keypads include Digit keys, Enter, Delete, Clear, the decimal point (if
decimal point operation is enabled) and the minus sign (if the keypad’s
data type is Signed Integer).
A maximum of 8 digits are displayed in the keypad’s scratchpad; the
decimal point and minus sign use one digit each. The data type, together
with the number of bits assigned to the Keypad Control Address and a PLC
input, determine the range of PLC values.
