master module.
Goes on when the AS-Inter face power is supplied sufficiently.

FLT

(Fault)

Indicates the AS-Inter face configuration status.
Goes on when the permanent configuration data (PCD) stored in the AS-
Inter face master module EEPROM does not match the current slave con-
figuration, or configuration data image (CDI). Then, configuration is not
complete or an error was found on the AS-Inter face bus.

LMO (Local mode)

Indicates the mode of the AS-Inter face master module.
Goes on when the AS-Inter face master module is in local mode.
Goes off when the AS-Inter face master module is in connected mode.

CMO (Connected mode)

Indicates the mode of the AS-Inter face master module.
Goes on when the AS-Inter face master module is in connected mode.
Goes off when the AS-Inter face master module is in local mode.

OFF (Offline)

Indicates the operating status of the AS-Inter face master module.
Goes on when the AS-Inter face master module is in normal protected
offline.

CNF (Configuration)

Indicates the configuration status of the AS-Inter face master module.
Flashes when the AS-Inter face master module is in configuration mode.

Input LEDs

IN0-IN3

Indicates the operating status of four inputs at the address indicated by
the address LEDs.
Goes on when the corresponding input at the indicated address is on.

Output LEDs

OUT0-OUT3

Indicates the operating status of four outputs at the address indicated by
the address LEDs.
