•
suppression_values
Space separated numeric values to be used in suppression.
•
suppression_time_ms
Suppression time in milliseconds.
•
operation
Mathematical or logical operation to be used for signals defined in
source_signal_alias
column. Following mathematical operations for source signal values can
be used:
avg
(average of all values),
min
(lowest value),
max
(highest value),
median
(median
value) and
sum
(all values accumulated to a single number). Logical operations, intended for
unsigned integers only, are
or
and
and
operations.
•
bit_select
selecting an individual bit of an integer number; bit numeration starts from zero.
•
math_expression
a mathematical expression for signal value to be evaluated against.
Explained in detail in section 17.2.7.
17.2.3 Signal recalculation operation priority
A value generated by some protocol usually has to be recalculated in one way or another. This
might mean changing the value of an argument as well as adding flags needed for other protocols
to correctly interpret results. As recalculation is a sequential process, some actions are done before
others. The sequence of operations done to a value is as follows:
•
Edition of attributes
. Attributes for further interpretation are added. This might, for example,
include flag to show that a signal resembles an answer to a command;
