NIB-96 Software Changes with Master AM2020/AFP1010
The NIB will detect an invalid polling scheme if one or more of the following condi-
tions exists:
NIB software P/N 73359 or lower
1. Communication at the two restricted NIB SLC loop addresses (someone
has programmed point 2 or 4, or both).
2. No communication for more than 60 seconds at one or more of the NIB
SLC loop addresses (except those restricted above) defined by the NIB
size switch.
NIB software P/N 73454 or higher
The NIB will detect an error if there is no communication for more than 60
seconds with one or more of the NIB points 1, 3, 4 or 5 through NIB SIZE
from the master SLC loop.
If the conditions above are detected, the AM2020/AFP1010 will enter the trouble
mode and display 'TROUBL LIB XX NIB M/S PROGRAMMING ERROR' or the
equivalent.
When excessive noise is detected on the LIB SLC loop connection to the LIB, the
AM2020/AFP1010 will enter the trouble mode and display 'TROUBL LIB XX NIB
COMMUNICATION ERROR' or the equivalent.
