摘要:
An I/O circuit for use with an industrial controller provides a photovoltaic optical isolator communicating between a controller and a field-side of the I/O circuit, the photovoltaic optical isolator eliminating the need for high wattage power dropping circuits for powering the field-side of the I/O circuit from high-voltage field signals. The field effect transistor type transistors permit use of the low-power photovoltaic optical isolator while allowing flexible connections to various field circuit types.

An I/O module samples an industrial process to acquire data indicative of performance of the industrial process. The I/O module has an internal memory in which the data from multiple samples is stored until readout by, or produced to, an industrial controller. The I/O module assigns a time-stamp identifier to the stored samples thereby providing time information to the industrial controller for the stored data when read out by the industrial controller.

摘要:
An input module for an industrial controller is configurable to simplify setup and commissioning. The input module includes input terminals configurable, for example, as a counter input. Still other input terminals may be configured to trigger events as a function of the input signals present at the terminals. Time signals corresponding to transitions in state of the input terminals, triggering of events, or operation of the counters may be recorded. The input module is further configurable to transmit data back to the processor or to transmit data directly to another module in the industrial control network.

摘要:
A system and/or method for synchronizing one or more modules of an industrial controller relative to a common time base. A module may be programmed and/or configured to employ an activation interval for controlling periodic activation for sampling one or more inputs and/or applying data at outputs of the module. The module synchronizes its activation interval based on a coordinated time base signal.
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.
