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： 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.

摘要： Systems and methods that efficiently simulate controlled systems are presented. A simulation management component (SMC) controls simulation of a controlled system by controlling a desired number of nodes, each comprising a controller (e.g., soft controller) and a simulated component or process, which are part of the controlled system. The simulation can be performed in a step-wise manner, wherein the simulation can comprise a desired number of steps of respectively desired lengths of time. For each step, the SMC dynamically selects a desired clock (e.g., currently identified slowest clock) as a master clock for the next step. The SMC predicts a length of time of the next step to facilitate setting a desired length of time for the next step based in part on the predicted length of time. As part of each step, components can synchronously exchange data via intra-node or inter-node connections to facilitate simulation.

摘要： A method of transmitting high speed serial data with reduced levels of radiated emissions is disclosed. A transmitting device scrambles data utilizing a pseudo-random number sequence generator. Scrambling the data eliminates transmission of repeated data sequences. The transmitting device similarly scrambles idle pairs of data between data transmissions to eliminate an additional source of repeated data sequences. The scrambled and encoded data is transmitted to a receiving device. The receiving device also includes a pseudo-random number sequence generator. Synchronization of the two pseudo-random number sequence generators occurs by utilizing control characters of the data frame being transmitted. Each of the pseudo-random number sequence generators is configured to generate the same sequence of numbers and is initialized to start with a first number in the sequence of numbers corresponding to the first byte of data being transmitted or received.

摘要： An industrial controller module (13a) is provided with a routine of program instructions (29a) for storing a log of I/O table state changes (31) in a defined portion of memory (23). Upon the occurrence of a trigger event, a file of the state changes (37) is saved in the memory (23). Each entry (32) in the log of I/O table state changes (31) includes a timestamp (33) and values of each word of I/O state data (36) that changed at a time of the timestamp. Logs of state change data (16a), including timestamp data can also be saved for intelligent sensors and actuators (16) and uploaded with the log of controller processor state data (31) to a computer (20) with a diagnostic program (21a) for playing back the state changes and synchronizing changes of the intelligent sensors and actuators (16) with changes of the controller processor module (13a).

摘要： An input module for an industrial controller includes configurable execution windows. The execution windows are defined by a first parameter and a second parameter stored within the input module. A third parameter defines a status bit which is compared against the execution window to set a window output signal within the input module. The execution window may define a range between the first and second parameters against which the status bit is compared. Alternately, the first and second parameters may define setpoints against which the status bit is compared. At one of the setpoints, the window output signal is set and at the other of the setpoints, the window output signal is reset.

摘要： A simulation environment is provided for running a process simulation used to validate an industrial control program. The simulation environment exposes the I/O module configurations defined in the control program and retrieves module configuration information therefrom. This I/O module configuration information is combined with generic, module-specific I/O module profiles to create a pool of available controller I/O points, which can be selectively associated with I/O points in the simulation to create an I/O point mapping. During control program validation, simulated I/O data is exchanged between the process simulation and the I/O module instances in the controller in accordance with the I/O point mapping. A variation of these techniques for use with cloud-based emulations is also described.
