GEN (FB)

FUNCTION_BLOCK GEN

Generates periodic functions of different, given types

The generation may be done relative to a specific time base or a given call-count base (BASE). An example set of available types of periodic functions are shown in the following image.

InOut:

Scope	Name	Type	Initial	Comment
Input	MODE	GEN_MODE		Types available: TRIANGLE: Triangular from -AMPLITUDE to +AMPLITUDE TRIANGLE_POS: Triangular from 0 to +AMPLITUDE SAWTOOTH_RISE: Sawtooth increasing from -AMPLITUDE to +AMPLITUDE SAWTOOTH_FALL: Sawtooth decreasing from +AMPLITUDE to -AMPLITUDE RECTANGLE: Rectangular switching from -AMPLITUDE to +AMPLITUDE SINE: Sine COSINE: Cosine
	BASE	BOOL		FALSE: Period referring to call ( CYCLES) TRUE: Period referring to time ( PERIOD)
	PERIOD	TIME	TIME#1s0ms	Period time, only relevant if BASE = TRUE
	CYCLES	INT	1000	Number of calls per period, only relevant if BASE = FALSE
	AMPLITUDE	INT		Amplitud of the function to be generated
	RESET	BOOL		TRUE: Sets OUT to zero
Output	OUT	INT		Generated function value
