1. A method of controlling an optical sensor device configured on a textile machine, the optical sensor configurable between a primary operating mode that transmits and receives a first form of reflected radiation that senses a state of a physical quantity related to ongoing production of a textile product at a workstation of the textile machine and a secondary operating mode that receives a second form of reflected radiation that provides information regarding service operations at the work station from a change in an operating state of the textile machine, the method comprising:
targeted switching of the optical sensor to the secondary operating mode when the service operations are required and detection of the physical quantity at the workstation is not required; and
evaluation of the second form of radiation with a control and evaluation device for subsequent targeted switching of the optical sensor back to the primary operating mode when the detection of the physical quantity of the product at the workstation is required.
