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 configured 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 85), 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.
