Method and apparatus for analyzing machine control systems

摘要

A diagnostic system analyzes conditions of critical points in a production line. The diagnostic system generates an operator message based on the conditions it analyzes. A sensor senses the conditions of the critical points in the production line and generates critical point signals representative of the conditions of the critical points. An isolator receives the critical point signals and generates logic signals representative of the critical point signals. The isolator isolates the logic signals from the critical point signals. A controller receives the logic signals and generates an operator message based on the logic signals.
