  • Patent number: 8949480
    Abstract: 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.
