Numeric Input Configuration
How you configure the numeric input determines the values the
operator can enter at runtime.
Field Meaning
Decimal Point ISpecify whether the operator can enter a number with decimal
points.
Disabled—the operator cannot enter a decimal point.
Implicit—allows the operator to enter the number and decimal point.
Use an analog tag with Floating Point data type.
Fixed Position—you specify where the decimal point is positioned in
the scratchpad display.
PLC Controlled—allows the PLC to determine the number of digits
that appear after the decimal point by specifying a value at the
Numeric Decimal Point Position control.
The PLC Controlled decimal position can display 1 to 15 decimal
digits. If the value returned by the Numeric Decimal Point Position
control is outside this range, the decimal point character is replaced
by a single asterisk (*).
Decimal Key Controlled—allows the operator to enter the number
and decimal point. The terminal calculates the decimal point position
and writes this value to the Numeric Decimal Point Position control.
See “Using the Decimal Point” later in this chapter for more
information.
Digits after
Decimal Point If you have selected the decimal point as Fixed Position, specify the
number of digits to follow the decimal point, up to a maximum of 15.
Auto-Repeat Rate
(per second) When the operator holds down the Raise or Lower key, the terminal
begins changing the value in the Keypad Numeric Input control by
the specified Amount per Increment/Decrement value, at the rate
entered in this field. Specify a number between 0 and 20 (per
second).
A value of 0 disables auto-repeat.
Auto-Repeat Start
Delay Specify the time, between 200 ms and 2.5 seconds, that the operator
must hold down the Raise or Lower key before the auto-repeat
function starts.
Amount per
Increment/
Decrement Enter a value between 1 and 2,147,483,647 if the decimal point is
disabled. If the decimal point is enabled, enter any value between
0.0000000001 and 2,147,483,647. The number can have a
maximum of 10 digits. The decimal point is not considered a digit.
The value at the Keypad Numeric Input control will change by this
amount each time the operator presses the Raise or Lower key.
