The signals are configured with the PLC function, as shown in Figure 11.3-30. The PLC can be
segmented into A to E blocks:

A Judgements of validities coming from automatic supervision functions

B Collection and exclusion logics of the judgements results

C Generator logic of U16_00 quality bits

D Generator logic of U16_01 quality bits

E Test bit generator.
