you can reference other WWW servers and display images from other
sources without affecting your usage of data table memory (except for
the size of the HTTP reference)
Referencing Data Table Memory - reference data table memory locations
by placing custom tags into your HTML source which specify the data table
location and optional formatting information. Use the following format for
the custom tag:
<!ABDTR-file_type{file_number}:{file_element}[,#elements]
[%format]>
The items surrounded by {} are sometimes optional. The items
surrounded by [] are always optional.
You must always specify the basic file reference. Depending on which
file is being referenced, file_number or file_element may be defaulted.
If the file_type is I, O or S, the file_number does not need to be
specified, but the file_element must be specified. If the file_type is not
one of the three special files, the file_number must be specified and the
file_element may default to zero (the input, output and status files have
fixed numbers).
Other considerations:
#elements - if not specified, this defaults to one. If less than one, also
defaults to one. Each element gets output using the same format
(whether specified with %format or defaulted).
%format - legal values are %d for decimal and %x for hexadecimal. The
following file types allow the format to be specified:
• Input •
• Output •
• Status •
Display format defaults - Input and Output file elements are output in
octal format. Status and BCD file elements are output in hexadecimal
format with a leading 0x. Integer file elements are output in decimal
format. Complex data types (Timer, Counter, MSG, BT, Control, PID,
SCF) are output as a table with bits and important words specified.
Fixed display formats - float files are always output in floating point
format ("C"%g format). ASCII and string files are always output as a
null terminated text string. Binary files are always output as two binary
bytes.
