If the NT8 is configured and a rack fault occurs, clear the NT8 Configured bit (B3/4) to initiate the NT8 configuration process.
Until the NT8 is configured, send the 8 configuration words (N12:10 - 17) to the NT8 using repeating BTW’s.
If the NT8 is configured, read the 8 input words into N12:0 - N12:7 using repeating BTR’s.
When the NT8 is configured latch the NT8 Configured bit (B3/4).
