Sensor debouncing

If there is bouncing at the signal output of the sensor, the input signal of the internal logic of the fieldbus controller might be misinterpreted. This may result in a faulty behavior, e.g. jam error. If sensor debouncing is active, after a signal change at the sensor input (edge), the resulting logical state is saved. The logical state remains active for the time set under the sensor debouncing parameter, independent of the actual signal state at the input. Note that the time T_E must not exceed the cycle time of the material T_D: T_E ≤ T_D.
