Abstract
A method for reliable position monitoring includes: (a) transmitting two measured position values from a position measuring device to a first processing unit; (b) transmitting a setpoint value from a setpoint value generator to a second processing unit; (c) transmitting one of the two measured position values to the second processing unit; (d) transmitting the setpoint value to the first processing unit; (e) performing mutually independent comparisons between the setpoint value and the measured position values by the first processing unit and the second processing unit; and (f) monitoring the measured position values for an electronic shaft break between the position measuring device and the first processing unit. The position values are different and have a defined relationship with respect to each other, and the transmitting (a) includes alternately transmitting the two measured position values to the first processing unit.
