Input PLC Parameters

Input​

  • The Input parameter is used for physical inputs on the PLC.

    • This parameter is only available for CM3 PLC CPUs.

  • Pulse Input Catch:

    • This is used for high-speed counting inputs.

  • Digital Input Filter:

    • The digital input filter is a feature that eliminates noise from input signals.
      • This is useful when on-site conditions are noisy or pulse-width is an important factor.
      • By controlling the digital input filter, it can increase the reliability on input pulse.
        • If the input signal is shorter than the pre-defined digital input filter time, the signal is recognized as an invalid signal and ignored by the module.
      • The digital input filter also applies to noisy or chattering pulses.
    • The selected addresses will apply the user input filter value.
      • The minimum input filter value is 1ms.
    • The unselected addresses will apply the standard input filter value.
