The Inter-PN Index screen the state-of-health vector is used to track and compare the states of
health of both PNCs. The fields making up the indexes are 2-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 present for that class. Increasing numbers indicate increasingly higher
numbers of faults present in that class.
The Inter-PN Index contains four fields (XX.XX.XX.XX). The Inter-PN Index reports faults in
connectivity between PNs.
● The meaning of each fault class field is given in Table 43: PNC State-of-Health Fault
Classes.
● A zero entry indicates that there are no faults reported.
● Higher numbers indicate increasing number of faults.
● All zeros indicate a perfect state of health.
● Unless the PNCs are locked, the active PNC’s state of health should always be equal to or
better than the standby’s. Otherwise, the system performs a spontaneous interchange.
