A system and method for online simulation of a controlled machine or process utilizes a simplified model of the system dynamics and may be used with hardware in the loop to evaluate performance of the controlled system or with software in the loop to perform commissioning of the control program prior to completion of the mechanical installation. The simplified model includes dominant order dynamics of the controlled system such as the inertia of the system and a damping factor. Further, the online simulation is scheduled to execute at an update rate slower than the update rate of the control loops within the motor drive. The simplified model and reduced update rate reduce the computational burden on the processor such that the simulation may be performed either on the industrial controller or on the motor drive.

The disclosed subject matter comprises a design management component that facilitates managing and storing information, including respective customized information of respective entities and/or relating to objects, projects, controllers, or industrial automation systems within a project file or controller. The design management component facilitates enabling custom data, including custom metadata, to be injected by object into a project file or in a controller associated with the project file. The design management component operates with a data management component that can allow respective entities to view, edit, or delete their respective data on objects associated with a project file or controller in accordance with their respective rules. The design management component facilitates desired library management, version management, virtualization of a system for emulation and testing, data exchange between application, and application development and management in relation to controllers, devices, or components, in connection with control of industrial automation systems.

Custom properties in an application environment

A system for generating electronic cam profiles mimicking the action of mechanical cams operates on a variety of different cam profile inputs and converts them into a common form, for example, expressed as a polynomial spline and modifies that common form by predetermined adjustment relationships, for example by scaling coefficients of the common form cam profile according to desired changes in cam function and/or limitations in dynamic cam values input by a user. The common form of the cam profile may be obtained from a table of cam values by spline interpolation of those data values.

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

Capturing data during operation of an industrial controller for the debugging of control programs

A system for troubleshooting control programs employs an event log that captures the values of inputs to outputs from the control program only at event times determined by changes in input or output data. The program allows the event log to be reviewed in jumps to only events which cause a change in output value of an instruction or particular change in output value of a particular instruction, greatly simplifying the troubleshooting process. The event log records a particular instruction instance associated with the event permitting the operation of the program to be studied in reverse order. The event log may also record a timestamp of the event allowing time stamped data from different devices to be synchronized with the review of the events.
