Patent number: 7048438Abstract: A method and system for automated temperature measurement is described. The system includes a programmable logic controller, a temperature measurement diode, an analog-to-digital converter coupled to the diode and the programmable logic controller, a current source coupled to the diode and configured to generate a first current and a second current different from said first current, and a processor coupled to the current source and to the analog-to-digital converter. The processor controls the current source such that the current source sequentially applies the first current to the diode at a first point in time and applies the second current to the diode at a second point in time. The processor also receives a first voltage across the diode measured when the first current is applied to the diode and a second voltage across the diode measured when the second current is applied to the diode. Based on the first and second voltages, the processor determines the temperature proximate the diode.Type: GrantFiled: September 30, 2003Date of Patent: May 23, 2006Assignee: Schneider Automatic Inc.Inventor: Richard H.

Patent number: 6744393Abstract: Analog input module for a programmable logic controller, the analog input module having an input circuit with terminals for accepting either a single voltage range or a single current range from process control sensors. The analog input module includes an analog-to-digital converter and an input circuit with an output terminal connected to the input of the analog-to-digital converter, a voltage input terminal, a current input terminal, and a common terminal. The input circuit is configured to accept a voltage input between the voltage input terminal and the common terminal, to accept a current input between the current input terminal and the common terminal, and to provide an output voltage at the output terminal dependent upon either the voltage input or the current input, without switching or configuring between them.Type: GrantFiled: December 21, 2001Date of Patent: June 1, 2004Assignee: Schneider Automation Inc.Inventor: Richard H.

Patent number: 6738441Abstract: A method and device for filtering an input signal received by an input module in order to produce a filtered input signal, wherein the received input signal is converted such that it has either a HIGH input state or a LOW input state each having a time duration characteristic of the input module, and the filtered input signal is represented by an ON filtered state and an OFF filtered state. The time duration of the HIGH input state and the LOW input state are determined by sampling the converted input signal at a certain sampling rate so as to allow the sampling results to be used by a filtering algorithm to set the filtered input state to ON or OFF based on a set of filter parameters which may vary from one input module to another. The filtering device is adapted to be configurable such that the filter parameters can be electronically selected so that the same filtering algorithm can be used for different input modules having different electrical characteristics.Type: GrantFiled: July 5, 2000Date of Patent: May 18, 2004Assignee: Schneider Automation Inc.Inventors: Steve R. Webster, Richard H. Breinlinger, Kenneth L. Wester
