Pulse Width Modulated Outputs for an Output Module in an Industrial Controller

摘要

An output module for an industrial controller configurable to simplify setup and commissioning is disclosed. The output module includes configurable PWM outputs that may be scheduled to start at different times within the PWM period, that may be configured to generate a fixed number of PWM pulses, and that may have an extendable PWM period. The output terminals are configurable to enter a first state upon generation of a fault and further configurable to enter a second state after a configurable time delay following the fault being generated. The output module may receive inputs signals directly from another module and set output signals at the terminals responsive to these signals.

1. An output module for an industrial controller, comprising:
a plurality of output terminals configured to generate an output signal; a memory device configured to store a series of instructions and a plurality of configuration parameters, wherein the configuration parameters define at least one pulse width modulated waveform; anda processor configured to execute the series of instructions to:
read the configuration parameters, generate each pulse width modulated output waveform as a function of the configuration parameters, and output each pulse width modulated waveform at one of the output terminals, wherein the configuration parameters define at which of the plurality of output terminals each pulse width modulated waveform is output.
