Floating-point numbers can be followed with an optional precision
specifier which will be used as an argument to printf’s %f format (for
example, a field of ‘4’ would be translated into the printf command of
‘%.3f’). Alternately, the special character ‘*’ can precede the precision
specifier; this causes an indirection on the precision specifier (which
now becomes a field number).
This is useful when formatting, for example, numbers which have
varying precision depending on the mode of the instrument.
Binary numbers can also have an optional precision specifier which is
used to determine how many bits to print. For example, the specifier ‘b4’
will print the lowest four bits of the parsed number.
There are serious restrictions on where an ‘s’ field may appear: currently
sources 1 and 2 must be ‘s’, and no others may be ‘s’.
The value source is followed by optional alarm information, indicated
by a commercial at sign ‘@’ with a source indicator and a starting bit
indicator. All alarm information is presumed to be two bits long (low
and high). The bitfield extraction is performed on the integer part of the
source. Typical alarm information would appear as ‘@6.4’.
Then, there appears an optional translation table within braces ‘{}’.
This is a string of words separated by spaces. An example translation
table would be ‘{Code_0 Code_1 Code_2 Code_3}’. The value, once
extracted, is used as a zero-based index into the translation table to
determine the string to display.
Then there appears an optional selection table within parentheses ‘(...)’.
This is a string of numbers separated by spaces ‘(0 1)’. The selection
table lists the translation table entries which the user may select from
when setting the parameter. This is not necessarily the same as the
entries which may be displayed.
Then there appears an optional button designator. This will be one of ‘B’,
‘I’, ‘L’, ‘T’, or ‘N’.
B- Indicates a button which pops up an input dialog prompting the
user for a new value using the designated input format. The input
format is specified from the ‘B’ through the subsequent semicolon.
I—Indicates a button which pops up a selection list with input
translation. That is, the values read are translated before they are
compared to the selection list options.
L—Indicates a button which pops up a selection list without any
translation. The output value is the number of the selected option.
