Abstract

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.

First claim

We claim:

1. A module for an industrial controller, comprising:
a plurality of terminals, each terminal configured to transfer a signal between the terminal and a remote device, wherein the signal is in one of a first state and a second state;
a clock circuit generating a time signal;
a memory device configured to store a series of instructions, at least one first register corresponding to each of the terminals, and at least one second register corresponding to each of the ter…
