12.1.8.1 Examples to display PLC data in an HTML page
FP Web-Server V2.810 EN
(STRING[])
S = string without "Header". Generated like with F95. (WORD[])
c = a single ASCII character
long Type
ld = 32-bit decimal, whole-numbered (DINT)
li
= 32-bit decimal, whole-numbered (DINT)
lu = 32-bit unsigned decimal, whole-numbered (DWORD)
lo = 32-bit unsigned octal (DWORD)
lx = 32-bit unsigned hexadecimal, lower case (DWORD)
lX = 32-bit unsigned hexadecimal, upper case (DWORD)
precision
A number that defines the number of decimal positions for displaying
floating point numbers (types: 'f' 'e' 'E' 'g' 'G').
When used with 16- or 32-bit integers (types: 'd' 'i' 'u' 'o' 'x' 'X' 'ld' 'li'
'lu' 'lo' 'lx' 'lX') a decimal point is placed in the integer number string.
The number of decimal places defined with the 'precision' ranges from
1 to 9. Refer to Example f.) in Examples to display PLC data in an
HTML Page (see p. 91).
width
A number that gives the minimum length of the field. If the number is
shorter, the field is filled up with spaces (or zeroes).
flags
The following characters are permitted:
+ = The algebraic sign (+ or -) is always indicated.
0 = Leading zeroes are indicated.
' ' = (blank character) Prefix the output value with a blank if the
output value is signed and positive.
# = Forces the output value of the e, E, or f format to contain a
decimal point (but only if digits follow). When used with the g or G
format, the # flag also prevents the truncation of trailing zeros.

pages (see "Defining input fields for PLC data on HTML pages" on p. 101)'.
