Patent number: 7996104Abstract: A method and control system are provided for controlling a modular conveyor system, which may be networked together with other such systems in order to implement a control strategy for a modular conveyor system. The control system comprises a communications port for interconnection of the control system with a network for sending outgoing addressed data to other devices on the address-based network and for receiving incoming addressed data from other devices. The control system further comprises a logic system, which may receive a signal from an object sensor and provide a control signal or output adapted to control activation of a motorized roller assembly, based on an input signal from the object sensor or the communications port. The logic system may provide for single step operation whereby system troubleshooting may be facilitated, and in addition may provide situation aware and output value source selection functionality.Type: GrantFiled: April 25, 2005Date of Patent: August 9, 2011Assignee: Rockwell Automation TechnologiesInventors: Wayne Wielebski, John P.

Patent number: 6745232Abstract: A method and system are provided for executing a control function or program which minimizes or overcomes the shortcomings of conventional systems. The invention allows a user of a distributed control system to place one or more control devices into a step mode, wherein the devices will execute a specified number of iterations of their internal logic or control programs, or execute such programs for a specified time period, and then stop or suspend execution. The user may then perform system diagnostics, for example, by interrogating certain modules to obtain output and input values, etc. The system may then be further iterated and the method repeated, so as to enable the identification of logic programming and/or hardware problems in a system.Type: GrantFiled: August 23, 2000Date of Patent: June 1, 2004Assignee: Rockwell Automation Technologies, Inc.Inventors: Steven P.

Patent number: 6591311Abstract: A method and system for selecting an output value source for an industrial control device are disclosed. The invention avoids the problems associated with conventional output devices by allowing a user to define one or more attributes associated with the output device, as well as defining a binding to local logic. The user may thereby determine or select the output value source which will be used by the output device under a variety of system conditions, depending on configuration of the output device or module, the current state of the module, and the state of a network. The method provides associating the output device with a logic function, providing the output value according to the logic function, ignoring explicit messages from the network, ignoring value messages from the network, selectively ignoring fault messages according to an override attribute, and selectively ignoring idle messages according to the override attribute.Type: GrantFiled: April 27, 2000Date of Patent: July 8, 2003Assignee: Rockwell Automation Technologies, Inc.Inventors: Steven P.

Patent number: 5555438Abstract: An industrial controller Input/Output module includes on-board processing circuitry in the form of a microprocessor and associated memory, a first programmable logic circuit and a second programmable logic circuit connected through an isolation interface. The isolation interface is comprised of optical coupling circuits. The programmable logic circuits are programmed to provide circuitry for parallel-to-serial data conversion of 24 bits of system Input/Output data on each side of the isolation interface. The data is then transferred as serial data in both directions at once in response to a shift clock signal. The data signals and the shift clock signal utilize three one-bit optical coupling devices in the isolation interface. After transfer across the isolation interface, the system Input/Output data is converted to parallel data for further processing.Type: GrantFiled: May 18, 1995Date of Patent: September 10, 1996Assignee: Allen-Bradley Company, Inc.Inventors: Steven P.
