Node 30 is an 8-point input/8-point output combination module.
Node 31 is a 12-point input module.
If the input status is not OK, then latch the inputs faulted indication.
If the raising edge of the fault reset signal is detected and the input status is OK, then unlatch the inputs faulted indication.
If the inputs do not have a fault, then write the input tag values to the internal representations of the inputs.
If the inputs do not have a fault, then write the input tag values to the internal representations of the inputs.
If the inputs faulted indication is true, then set the internal representations of the Diverse inputs to their safe state (1).
