Schneider Electric 890USE17700 manual faults were detected

Data Exchange

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:

A value of 1 in a bit indicates that the associated module is operating and that no

￿faults were detected.

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:
