PNC State of Health
PNC-DUP software monitors the health of the two PNCs as determined by their state of health 
(SOH) vectors, and initiates an interchange when the health of the active falls below that of the 
standby (unless prevented from doing so by a PNC lock, busyout, or anti-thrashing 
mechanism). Potentially service-disrupting faults which occur in PNC components are reported 
to PNC-DUP and incorporated in the state of health for the affected PNC. The SOHs of both 
PNCs are displayed on the status pnc screen.

PNC State-of-Health Indexes
The Inter-PN and Inter-SN Indexes form the state of health vector, which is used to track and 
compare the states of health of both PNCs. The fields making up the indexes are two digit 
numbers separated by periods (.), with each field representing a different class of faults. The 
fault class fields are arranged in order of decreasing importance from left to right. In other 
words, each field in the index supersedes the following fields in determining which PNC is 
healthiest. A fault class drives an interchange only when all of the higher priority fault classes 
are equal. A zero entry indicates no faults in that class. Increasing numbers indicate 
increasingly higher numbers of faults present in that class.
