display.inputvalue
Function Displays a formatted input field that the operator can edit.
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 Define format string for the input field using ‘0’s, 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
• This function will make use of text to create an editable input field on the user screen
at the present cursor position. The first write to the display after poweron will clear
the user screen.
• Examples of the input field:
+0.00 00 +00.0000E+00 0.00000E+0
Value field:
+ Include a “+” sign for positive/negative value entry. Not including the “+” sign
prevents negative value entry.
0’s‘ Defines the digit positions for the value. Up to six ‘0’s 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’s‘ 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 (e.g., -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.
• Message prompts to instruct the operator should be displayed prior to calling this
function. Make sure to position the cursor where the edit field should appear.
• The input value is limited to ±1e37.
