Real Time Average Calculates the average value of a parameter over a user-configurable duration. The output of the
math block is updated at the end of the set duration only. A reset signal can be configured to
restart the calculation of the average value.
The average value is stored in case of power failure. If the duration of the power failure is longer
than the Average Duration (see page 66), the math block output value is set to zero.
Max Hold The math block output represents the highest value of the signal since it was reset.
Min Hold The math block output represents the lowest value of the signal since it was reset.
Multiplexer Enables 1 of 2 analog signals or constant values to be selected using a digital signal.
Square Root Calculates the square root of the selected sources value. If the input is less than 0, the output is
set to zero and the math block output state set to invalid.
