  • Page 28: Enhanced Functional Blocks

    Enhanced Functional Blocks The following sections provide descriptions of the enhanced functional blocks. Timer The timer generates a pulsed digital signal with a configurated frequency and duty cycle. The timer can be configured to emit a continuous (periodic) pulse. The timer can also be configured to emit a single pulse after receiving an input trigger signal.
  • Page 29 Rescaler You can use the rescaler to change the frequency of a periodic input signal. The rescaler can multiply the period by up to 4096 or divide it by up to 4095. The rescaler samples the frequency of the input signal, calculates the new output frequency, and emits a clock with a 50% duty cycle.

  • Page 30: Plc Signal Descriptions

    The delayer uses the rising edges of a periodic reference signal for timing. On each rising edge of the reference signal, the delayer samples the input signal. After n pulses (up to 65535) of the reference signal, the delay outputs the sampled value. The delayer can store up to 128 transitions (64 pulses). Because the delayer uses the reference timing signal for sampling, input pulses that are shorter than the period of the reference timing signal could be missed.
