Foundation Block Set

Foundation Control Block Set

First Time Block:

The first time block sends a true signal out the first time the subsystem it is in is triggered. All other executions of that subsystem will have this block output a false signal.

Compare To:

The Compare To block allows the user to compare an inputted value vs. the given value in the mask. It will output a true signal when the values match.

Falling Edge:

This block detects a falling edge and outputs a value when it does so.

Derivative:

This block takes the derivate of an inputted signal.

Saturation:

The saturation block takes a min, max and inputted value. It then outputs the inputted signal when it is between the min max. When the inputted signal goes over the boundaries it outputs the min or max values.

First Order Low Pass:

The 'alpha' input is T/t. So when alpha = 1, the block simply passes the input through to the output, and when alpha = 0, the block forever holds its last output value.

Median Filter:

This filter block stores the number of data points that the user requests and gives the median of those values.

Time Since Enabled:

The Time Since Enabled block outputs the amount of time that has elapsed since the enable input has gone high. It holds its value when the enable input goes low, but resets again when it goes high.

Saturate Divide:

When the divisor is less than the numerator or zero, saturate and output one.

Integrator

The integrator block takes an incoming signal and integrates it. You can set a Min and Max value for the output. You can also enable the signal with the Rst signal, and it will output the IC value.

Simple PI, PD, and PID Blocks:
