B3 Sine Wave Generator
Sine wave generator
FB: LIB.CORE.V1_0.B3_SINUS_GENERATOR:= (T:= T#10S, MINIMUM:= -10, MAXIMUM:= 10);
FB(OUT => O1, TRES => O2);
The block generates a sine signal at which period, and minimum and maximum values can be set. Remaining time until end of the period is also indicated at the output.

The output signal OUT provides a sine wave signal with period of T a and lower/upper peaks MINIMUM and MAXIMUM respectively. There is a Tres signal which is time remaining until the end of the period T, see figure below. The block has a Boolean input ENABLE, which stops the generator (stopped: ENABLE: = false). The behavior after the block has been stopped depends on the PAUSING parameter (see figure below):
- PAUSING=FALSE and ENABLE=FALSE: the output OUT is set to MINIMUM + MAXIMUM / 2. As soon as ENABLE goes to TRUE, the period time starts from the beginning.
- PAUSING=TRUE and ENABLE=FALSE: the output OUT is frozen. As soon as ENABLE goes to TRUE, the sine wave continues from where it has been stopped.
Function B3 generates a sine signal at the O1 output with period of 10 seconds, minimum value of -10, and maximum value of 10.
