Explanations
ƒ Discrepancy time
Maximum time in which both channels of a safe input may have non−equivalent states
without the safety engineering causing an error response.
ƒ Input delay
Time between the recognition of the signal change and the effective evaluation of an
input signal. As a result, multiple and short signal changes due to contact bounce of the
components are not taken into account.
ƒ Input filter time
Time in which the interference pulses and test pulses are not detected by e.g. active
sensors that are switched on.
The input delay time and the time of the input filters influence the response time. More
information can be found in the "Response times" chapter (
¶ 107).
