摘要:
This invention provides an input device of a safety unit which enables an error diagnostic result referred by a safety init such as a safety controller (i.e. master) or a safety slave, in a process of generating control data from raw input signal from a safety application switch or the like, to be reffered by the controller side using that control data so as to achieve a variety of safety controls based on the control data. The input device contains a function of outputting status data indicating the error diagnosis result referred to when input signal is converted to control data and the control data obtained by the conversion in pair, so that when the logical value of the control data is "LOW", whether it originates from the fact that the raw logical value is "LOW" or from the fact that "LOW" is compulsorily set due to an error in the terminal, can be determined from the logical value of the status data.
摘要:
Sensors associated with a robot or sub-system thereof (e.g., a series elastic actuator associated with a robot joint) may be monitored for mutual consistency using one or more constraints that relate physical quantities measured by the sensors to each other. The constraints may be based on a physical model of the robot or sub-system.
摘要:
A method is for monitoring an industrial control system. The method comprises collecting data from one or more sources external to the industrial control system; collecting data from one or more internal sources on the industrial control system; aggregating data collected from said internal sources or from said external sources; correlating said collected data by analyzing and interpreting said collected data in view of previously collected data so as to monitor the security of the industrial control system. An apparatus is for performing the method.
