B-46 Model 49i Instruction Manual
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 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.
