FP Web-Server V2.810 EN
The setup of the field for PLC data display always has the format
{TTxxxy_aa_bb}
(for FP7
{TTxxxxy_aa_bb}
) with the following
parameters:
TT
PLC Data Type. Implemented PLC data identifiers:
DT, FL, LD, WI, R, X, Y
xxxy
xxxxy
Address of the PLC Data, e.g. DT200 or Y7.
The address range supported by the FP Web-Server is 0–32765.
For internal flags, the last position of the address is a hexadecimal number
from 0–F, e.g. R2F
For FP7, the supported address range is 0–999424. MEWTOCOL 7 must be
set for addresses above 32765.
aa
Numbers: Number of characters reserved in HTML. The rest will be cut off.
Internal flags: Text that should be displayed at internal flag state 0, e.g.
OFF
.
bb
Numbers: Number format, i.e. type of the display. See below.
Internal flags: Text that should be displayed at internal flag state 1, e.g.
ON
.
The data type and address part
TTxxx(x)y
can be replaced by the
corresponding variable name (see p. 96) from the FPWIN Pro project, e.g.
{'VarName'_aa_bb}
or
{'name'_5_i}
.
There is no space allowed between the curly bracket and the first
character. For example
{ DT3_4_u}
or
{ 'name'_5_i}
is not allowed.
It will be interpreted as a Java Script command and copied unchanged into
the final HTML file.
The setup of the format specification bb for numbers is
[flags][width][.precision][l]type
Only the specification 'type' is obligatory. The other inputs are optional. In
the following list the corresponding FPWIN Pro types are listed in brackets:
Type
d
= decimal, whole-numbered (16-bit,
INT
)
i
= decimal, whole-numbered (16-bit,
INT
)
u
= unsigned decimal, whole-numbered (16-bit,
WORD
)
o
= unsigned octal (16-bit,
WORD
) (only display, not for data entry)
x
= unsigned hexadecimal, lower case (16-bit,
WORD
)
X
= unsigned hexadecimal, upper case (16-bit,
WORD
)
f
= floating point number without exponent (32-bit,
REAL
)
e
= floating point number with exponent (small
e
for exponent,
REAL
)
E
= floating point number with exponent (capital
E
for exponent,
REAL
)
g
= either
e
or
f
, depending on what seems to be more compact
(
REAL
)
G
= like
g
, but the exponential display also taken into account
(
REAL
)
s
= FPWIN Pro strings with current string length in the "Header"
