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.
T—Indicates a button which pops up a selection list with output
translation. The number of the option selected is used as an index into
the translation table to generate an output string.
N—Indicates a button which only sends the subsequent command to
the instrument. No user-prompting happens.
The following string through an optional ‘|’ or the end of the line is the
command which is to be sent to the instrument upon the completion of the
button selection. The command string should normally contain print-style
formatting to include the user input. If a ‘|’ is present, it indicates a
command which is sent to the instrument upon successful completion of
the button command to update the value field.
