Abstract
A method is disclosed for diagnosis of actuators which are operated with the aid of a positioning device as a function of a nominal value preset, which is emitted from a superordinate regulation device and is received via a communication interface. Diagnosis information can be determined from a time profile of the nominal value preset by investigating the profile of the nominal value for one or more known characteristics.
Claims5
A method for diagnosis of an actuator for automation technology, comprising:
- emitting a nominal value preset for a positioning device associated with the actuator using a communication interface;
- and
- determining diagnosis information of the actuator from a time profile of the nominal value preset by investigating the profile of the nominal value for a known characteristic.
Dependencies are inferred from the claim text.
