Detect Rise Nonnegative
Detection of a rising edge, provided that the value of the signal increases to a non-negative value, and its previous value was strictly negative.

Description
Block Detect Rise Nonnegative determines that the current value of the input signal is greater than or equal to zero, and its previous value was less than zero.
-
The output signal takes the value
true (1)when the value of the input signal is greater than or equal to zero, and its previous value was less than zero. -
The output signal takes the value
false (0)if the value of the input signal is less than zero, or if it is non-negative and its previous value was also non-negative.
This block can only be used with discrete solvers.
