If you choose the PLC controlled decimal point, you must assign a
Decimal Point Position Address, a PLC input or output address. This
three-bit binary code indicates the number of digits to the right of the
decimal.
For example, a value of zero (000 binary) means that there will be no
digits displayed after the decimal point (and the decimal itself will not
be displayed); a value of three (011 binary) means there will be three
digits to the right of the decimal point; a value of seven (111 binary)
means that seven digits will be displayed to the right of the decimal
point. The remaining bits in the word address can be assigned to other
functions.
Decimal Key Controlled allows the operator to enter the number and
decimal point. The terminal interprets the decimal point position in the
window and sets the Decimal Point Position Address to that value.

To send a decimal point value to the PLC controller, define a Decimal
Point Position Address. In this case, only a PLC input can be used. The
three-bit value stored at this address determines the number of digits to
the right of the decimal point. Thus, the relationship between the
number and decimal point is implied; the number sent to the PLC
controller does not contain a decimal point.
When the Enter Key Control Address and the Enter Key Handshake
Address are assigned for Numeric Entry Keypads, the application file
created will only be compatible with Version 2 and later firmware.
IMPORTANT: The Numeric Entry Keypads are retentive objects. Your
PanelView terminal will retain the current value of Numeric Entry
Keypads 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 set for both.
