display.inputvalue
Function Displays a formatted input field that the operator can edit.
TSP-Link
accessibility
This function can be accessed from a remote TSP-Link node.
Usage There are four ways to use this function:
value = display.inputvalue(format)
value = display.inputvalue(format, default)
value = display.inputvalue(format, default, min)
value = display.inputvalue(format, default, min, max)
format
Defines format string for the input field using 0,
the decimal point (.), polarity sign (+) and ‘E’
for exponent.
default
Set the default value for the parameter.
min
Set the minimum input value that can be set.
max
Set the maximum input value that can be set.
Remarks • Examples of the input field:
+0.0000+00.0000E+000.0
• Value field :
+ Include a “+” sign for positive/negative value entry. Not including
the “+” sign prevents negative value entry.
0 Defines the digit positions for the value. Up to six 0 can be used for the value (as
shown above in the third and fourth examples).
• .If used, include the decimal point (.) where needed for the value.
•
Exponent field (optional) :
E Include the “E” for exponent entry.
+ Include a “+” sign for positive/negative exponent entry. Not including
the “+” sign prevents negative exponent entry.
0 Defines the digit positions for the exponent.
• Along with specifying the
format
for the input field, there are options to specify minimum and
maximum limits for the input field. When NOT using the “+” sign for the value field, the minimum
limit cannot be set to less than zero. When using the “+” sign, the minimum limit can set to less
than zero (for example, -2).
• There is also an option to specify a default value. When this command is executed, the initially
displayed value for the field will be the
default
value.
• The input value is limited to ±1e37.
Remarks
(cont.) • After sending this command, script execution waits for the operator to enter a value and press
ENTER :
• If limits are used, the operator will not be able to input values outside the minimum and maximum
limits.
• For positive and negative entry (“+” sign used for the value field and/or the exponent field),
polarity of a non-zero value or exponent can be toggled by positioning the cursor on the polarity
sign and turning the wheel. Polarity will also toggle when using the wheel to decrease or
increase the value or exponent past zero. A zero value or exponent (for e00) is always
positive and cannot be toggled to negative polarity.
• After sending this command and pressing the EXIT key,
value
will return
nil

Example Displays an editable field (“+0.50”) for operator input – Valid input range is -0.10 to +2.00, with a
default of 0.50:
display.clear()
value = display.inputvalue("+0.00", 0.5, -0.1, 2.0)
