(2) Status Memory
(a) The AES Controller remembers the following information:
• The AES Controller maintains an overall mode of operational state, of UNKNOWN
(Default), DATA LOAD, CRITICAL FAULT, COMMANDED MODE, OPERATIONAL
MODE.
• The AES controller maintains an overall service state, of AVAILABLE (default) or
UNAVAILABLE. This service state, when set to UNAVAILABLE, disables user
servicer and transmission.
• For each unique L1 thru L3 code, maintained across reset/power down, it records if
the code has occurred (SET), cleared after occurring (CLEAR), or never seen
(NO_ERROR).
• For each unique L1 thru L3 code, maintained across reset/power down, it records
the number of occurrences and the time of the last occurrence.
• For every link in the system, it records the status: UNKNOWN (default after power
on), DISABLED, INACTIVE, NO_LAYER_1 (when applicable),
HIGH_PACKET_LOSS, ACTIVE (normal). It also records the time of the last report,
and the long term link status: NOFAULT, FAULT.
• For every ARINC 429 label the AES accepts on a per LRU basis, it records the
status: DISABLED, UNKNOWN (default after power on), ACTIVE, SSMERROR,
MISSING.
• For every input discrete the AES LRUs possesses, it records the status: UNKNOWN
(default after power on), ASSERTED, DEASSERTED.
• For every temperature sensor on every LRU the AES controller records its status:
NORMAL (default after power on), WARNING, CRITICAL.
• For the Modman, KRFU, KANDU, TMA, FMA the AES controller records it overall
hardware state: NORMAL (default after power on), WARNING, FAILED.
• The AES controller maintains in memory the mute state of each LRU, and the
reason for mute. Default is "INITIALIZATION".
(b) The LRUs remembers the following information:
• For each unique L1 thru L3 code, maintained across reset/power down, it records if
the code has occurred (SET), cleared after occurring (CLEAR), or never seen
(NO_ERROR).
• For each unique L1-L3 code, maintained across reset/power down, it records the
number of occurrences and the time of the last occurrence.
• For every link the LRU has, it records the status: UNKNOWN (default after power
on), DISABLED, INACTIVE, NO_LAYER_1 (when applicable),
HIGH_PACKET_LOSS, ACTIVE (normal). It also records if the link is causing a
mute of the system.
