Abstract: A method and system for interacting with data frames passing through a module connected to an industrial network is disclosed. Each module includes an aggregation unit located on the network interface above the physical layer. To transmit data, the aggregation unit reads a header from a dynamic data packet to determine if the module is a participant module for the packet. If so, the aggregation unit inserts data from the module into the data packet and transmits the packet to another module. To receive data, the aggregation unit reads a header from the data packet to determine whether the data. packet includes data for the module. If so, the aggregation unit reads the data and passes the data packet to another module. If the aggregation unit determines that a data packet is not intended for the module, the data packet is passed to another module with no further interaction.

Abstract: 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.

Abstract: An improved system for handling events in an industrial control system is disclosed. A module in an industrial controller is configured to generate an event responsive to a predefined signal or combination of signals occurring. The event is transferred to an event queue for subsequent execution. The event queue may also be configured to store a copy of the state of the module at the time the event is generated. The event queue may hold multiple events and each event is configured to trigger at least one event task. Subsequent events that occur during execution of the event task are stored in the event queue for later execution. An event, or combination of events, may trigger execution of an event task within the module, within the controller to which the module is connected, or within multiple controllers.

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.

Abstract: A system for defining information for multi-option devices connected to an industrial network is disclosed. Each device has a single electronic data sheet (EDS) defining options associated with the device as well as each of the choices associated with those options. An option data sheet (ODS) is included for each option defining the device information corresponding to that option. A programmer interface may allow a programmer to select devices as well as the options for each of those devices associated with a control system. Each device is also configured to store the EDS and each ODS corresponding to that device within memory in the device. The programmer interface generates a controller configuration file defining the connections between each device and the controller.

Abstract: An industrial control system provides for distributed processing of position related signals by remote I/O modules to correct for spatial offsets of sensors or actuators associated with the I/O modules, the latter which may receive position data and may correct timing signals detected at the I/O modules according to a stored position offset within the I/O modules.
