Fault Detection The next eight contiguous registers (registers 45383 through 45390) indicate the
presence or absence of operational faults detected on the island bus modules. Each
bit represents a module:
z A value of 1 in a bit indicates that the associated module is operating and that no
faults were detected.
z A value of 0 in a bit indicates that the associated module is not operating either
because it has a fault or because it has not been configured.
The first two registers, shown below, provide the 32 bits that represent the module
locations available in a typical island configuration. The remaining six registers
(45385 through 45390) are available to support the island’s expansion capabilities:
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
