ALGORITHM REQ IN Java :
OUT.value = (IN.value < 50)?
100 - 2 * Math.abs(IN.value - 25) :
2
* Math.abs(IN.value - 75);
END_ALGORITHM
An instance of this Function Block type converts a sawtooth waveform
in the range
{0..100}
to a triangular waveform of the same frequency and the same signal
range, i.e., amplitude and offset of 50 units. Its operation is
modeled by the Execution Control Chart (ECC) and algorithm shown
above.
See the WAVEFORMS system
configuration for an example of the use of instances of this and
other waveform generation FB types.
