Random will output random values with a linear probability distribution between the specified lower and upper limits.

Parameter

Description

Lower Limit

Random value outputs will not go below this setting

Upper Limit

Random value outputs will not go above this setting

Example Usage as an Expression:

Random(0,1) - Returns random value s that vary between 0 and 1.

Random(-4.2,15.8) - Returns random values that vary between -4.2 and 15.8.

Example Reference Chart:

The following example shows Random(0,1) overlaid with indicators of the high, low, and mean values. A distribution from 0 to 1 has a highest value near 1, lowest value near 0, and a mean near the middle point between the bounds, which in this case is 0.5.

The example below shows random noise being added to a tank level, and then smoothed out afterwards. This illustrates that Random can be added to signals, and fed as input to other functions.
