The entered value is rounded to a multiple of 10 ms. Requirements Parameter settings: ● Sensor evaluation: 1oo2 evaluation ● Type of sensor interconnection: 2-channel equivalent or 2-channel non-equivalent Discrepancy Analysis and Discrepancy Time When using a dual-channel, or non-equivalent sensor, or two single-channel sensors which measure the same physical process variable, the sensors will interact with a slight time delay because of precision limitations in their arrangement. The discrepancy analysis for equality/non-equality is used at fail-safe inputs to detect errors based on the timing of two signals with the same functionality. Discrepancy analysis is initiated when different levels (when testing for nonequivalence: same voltage levels) are detected at two associated input signals. A test is conducted to determine whether the difference in levels (when testing for nonequivalence: the match) has disappeared after expiration of a specified time known as the discrepancy time. If not, this means that a discrepancy error exists. In most cases, a discrepancy time is started, but does not fully expire since the signal differences are cleared within a short time. Select a discrepancy time of sufficient length so that in case of no error, the difference between the two signals (when checking for nonequivalence: the consistency) has definitely disappeared before the discrepancy time expires. Response During Discrepancy Time While the programmed discrepancy time is running internally on the module, either the last valid valueor 0 is returned to the safety program on the F-CPU by the input channels involved, depending on the parameter settings for the behavior of discrepancy. Response During Discrepancy Time If the input signals are not equivalent following expiration of the specified discrepancy time (when checking for nonequivalence: no inequality), for example due to wire break at a sensor line, the system detects a discrepancy error and generates a discrepancy diagnostic message in the diagnostic buffer of the F-I/O module to identify the faulty channels.
