The function returns the difference between the minimum and
maximum values of given object for the time period elapsed.
Declaration
REAL %MaxDif(
REAL in Arg,
INT in timeInt
UNIVAL in trigger
)
Parameters
Arg
Variable which value increment / decrement is to be
calculated.
timeInt
Time interval [s] - calculation
time depth.
trigger
Object - a change of its value causes the function to be recalculated. Its type is optional.
Description
The function calculates the difference between minimum and maximum values
within the time interval defined by the parameter timeInt.
Return value
If minimum value is written before maximum one - the function returns a positive difference, i.e. increment.
If maximum value is written before minimum one - the function returns a negative difference, i.e. decrement.
If the object values within the given interval are the same, i.e. the same object values at the moment of
trigger change, the function returns the value of 0.
