    摘要: A method for testing the safety automation logic used in a manufacturing cell includes recording control signals of a safety-related component such as an E-Stop, light curtain, gate lock, or a safety mat using a host machine, and then disconnecting the component from the host machine. The recorded test signals are transmitted to an automation controller in accordance with a test scenario from a test scenario generator module (TSGM) to emulate operation of the component. The automation logic may be certified using the playback of the recorded test signals. A system for testing the safety automation logic includes the controller, host machine, and TSGM. The host machine records the control signals and plays back the test signals on the controller to emulate operation of the component. The automation control logic may be certified using the test signals, e.g., by comparing these to the test specification or standard.

    摘要: A method, system, and computer program product for automated root cause identification of a failure of a logic controller have been provided. The method includes receiving logic controller failure information, receiving a logic model of logic code for the logic controller, and mapping the logic controller failure information to the logic model to identify a logic failure model state. The method further includes determining a potential trigger of the failure of the logic controller as a root cause via tracing through at least one path in the logic model to reach the logic failure model state. The method also includes identifying the root cause in the logic code via mapping the root cause from the logic model to the logic code, and outputting the logic code with the identified root cause of the failure of the logic controller.

    摘要: Provided herein are systems useful in a manufacturing environment for transmitting operational commands to one or more workstations at which a workpiece is being acted upon by one or more pieces of manufacturing process equipment. A system according to the invention utilizes the 802.11a communication standard in conveying command signals wirelessly from a source to a programmable logic controller that is adapted to control the actions of a piece of manufacturing process equipment. A system according to the invention is adaptable to multiple-stage manufacturing operations through use of a plurality of receiving stations which are each equipped with a wireless modem in cooperative connection with a programmable logic controller that controls a particular piece of manufacturing process equipment at each stage. Systems and processes according to the invention are applicable to nearly any manufacturing process, and allow increased flexibility in management and configuration of manufacturing operations, while conferring a high degree of portability in many cases.

    摘要: A method for coding an event history is disclosed. Information relating to a real time state of an event is received. For a defined interval of time, it is determined whether the state of the event is in one of two states. In response to the event being in a first state, a data stream is appended with a first characteristic representative of the first state, and in response to the event being in a second different state, the data stream is appended with a second characteristic representative of the second state. The appended data stream is saved, and the process repeated for the next sequential defined interval of time.
