Fig. 98: Typical Timing Diagram for SF_Equivalent
The function block monitors the discrepancy time between Channel A and B, when switching to TRUE and
also when switching to FALSE.
Error Behavior
S_EquivalentOut is set to FALSE. Error is set to TRUE. DiagCode indicates the Error states. There is no
Reset defined as an input coupled with the reset of an error. If an error occurs in the inputs, a new set of
inputs with correct S_EquivalentOut must be able to reset the error flag. (Example: if a switch is faulty and
replaced, using the switch again results in a correct output.)
