Abstract: A system and method for developing a prototype that comprises a sequence of motion control, machine vision, and/or data acquisition (DAQ) “MC/MV/DAQ” operations. A MC/MV/DAQ prototyping environment may be designed to enable a user to easily and efficiently develop/prototype a MC/MV/DAQ sequence (i.e., a sequence of operations which includes one or more motion control, machine vision, and/or DAQ operations) without requiring the user to perform programming, e.g., without needing to write or construct code in any programming language. For example, the environment may provide a graphical user interface (GUI) enabling the user to develop/prototype the MC/MV/DAQ sequence at a high level, by selecting from and configuring a sequence of MC/MV/DAQ operations using the GUI.

Abstract: A system and method for utilizing a drawing specification for motion control. A plurality of elements in the drawing specification may be automatically identified. The elements may include one or more lines, polygons, arcs, splines, alphanumeric characters, and/or ellipses. Additionally, the drawing specification may be a drawing or digital drafting file, such as an AutoCAD file, among others. An order of the plurality of elements may be automatically determined according to a sorting algorithm. The sorting algorithm may include a geometric and/or radial sorting algorithm. The radial sorting algorithm may specify the order of the elements according to nesting and/or distance from the center of the drawing specification. Code may be automatically generated for implementing motion control based on the identified elements and the determined order. The generated code may include inserted operations such as raise, lower, and move operations, among others.

Abstract: System and method for automatically updating a memory map coupled to or included in a programmable controller (PrC). A PrC may automatically detect at least one programmable hardware element (PHE) coupled to the PrC. The PHE may provide a customizable interface, i.e., input and output (I/O) interface, between one or more devices and the PrC. The devices may include one or more measurement, data acquisition, signal generation, automation, motion control, and/or analysis device(s), among others. The PHE may perform one or more functions on the data transmitted between the device(s) and the PrC. One or more of the PHEs and/or device(s) may be local or remote to the PrC. The PrC may automatically update the memory map based on a hardware I/O interface of the at least one programmable hardware element, where the memory map facilitates communications between programs executing on the PrC and the programmable hardware element.

Abstract: Operating a programmable controller with a plurality of processors. The programmable controller may utilize a first subset of the plurality of processors for a scanning architecture. The first subset of the plurality of processors may be further subdivided for execution of periodic programs or asynchronous programs. The programmable controller may utilize a second subset of the plurality of processors for a data acquisition architecture. Execution of the different architectures may occur independently and may not introduce significant jitter (e.g., for the scanning architecture) or data loss/response time lag (e.g., for the data acquisition architecture). However, the programmable controller may operate according to any combination of the divisions and/or architectures described herein.

Abstract: A system and method for user configuration of an autotuning algorithm for a PID controller. User input is received via a Graphical User Interface (GUI) indicating a desired characteristic of a PID controller, such as stiffness or response time. The system is excited via a proportional controller to characterize the intrinsic behavior of the system, i.e., to calculate a system transfer function. An autotuning algorithm is configured in accordance with the user input. The configured autotuning algorithm is applied to the transfer function to generate gain values for the PID controller resulting in the PID controller characteristic specified by the user. The PID controller gains are loaded into the PID controller hardware or software, thereby configuring the PID controller to operate according to the desired characteristic specified by the user. The user may trigger and view a step response of the system to review the results of the tuning process.

Abstract: Devices and methods for synchronizing devices over a switched fabric. A master device maintains a global time, determines a mapping between the global time and a counter of a switch over a memory-mapped fabric, and sends the mapping to a slave device. A slave device maintains a local time, determines a first mapping between the local time and a counter of a switch, receives a second mapping between the counter and a global time of the master device, and synchronizes its local time to the global time based on the first and second mappings. The master and slave device may map their times to the counter by sending respective request packets to the switch and receiving respective completion packets including respective counter values from the switch. The master and slave device may determine respective time values corresponding to the respective counter values based on in-switch delays of the packets.
