Results in 1.0 (Pseudo-True) continuously, if the S input is Pseudo-True for at least one sample period, or results in 0.0 (Pseudo-False) continuously, if the R input is Pseudo-True for at least one sample period.

Flip-Flop (set/reset)

Overview

This operator functions as a set-reset flip-flop, using signal values of 0 (pseudo-false) or 1 (pseudo-true). If the Set input is 1 or greater than 1 for at least one sample period, the output becomes 1. If the Reset input becomes 1 or greater than 1 for at least one sample period, the output becomes 0.

Details

Pseudo-boolen signal values are values that are defined to be boolean False if they are 0, and boolean True if they are greater than or equal to 1. If boolean values are defined this way, a logical AND operation equals multiplication, and a logical OR operation equals addition. The set-reset flip-flop can be used to convert a short pseudo-boolean True value in a continuous pseudo-boolean True or False signal.

This operator expects both inputs to have an equal number of channels, or one input to have one channel. The output has the highest number of channels of both input channels.

If one input has one channel, the flip-flop is set or reset for all output channels at once. If both inputs have an equal channel count, the operation is carried out for every corresponding channel separately.

The first, or S input has priority above the second input. Output channel naming and numbering are copied from the S input. Therefore a feedback loop should be connected to the second (or R) input, in order to get consistent functionality.
