The entries are stored in a section of SRAM that can hold up to 900 separate entries. Each
time an event is recorded which exceeds this maximum, the new one overwrites the oldest
recorded event. The entries are saved during a power outage, but can be deleted with the
Clear Event Log option on the System Functions menu. Producing the report at this time
produces a "No Events" message. If events have been recorded and not cleared, they're
listed in chronological order, beginning with the most recently recorded event.
Listed below are many of the system events that are currently available for recording. Not all
of the available system events are listed. (Note that on the 2300-100 Processor board are two
processors, the Analyzer Processor (aka processor-A) and the Communications Processor
(aka processor-B). The Communications Processor has a hardware clock. The Analyzer
Processor has a firmware clock.)

Comm Sending Setup:(TimDat) is recorded when the Communications Processor
sends the Analyzer Processor the time and date. This happens every time the
customer changes these values and every morning at 01:00 a.m.

COP RESET Forced is recorded when the user forces a system RESET through the
Remote System Reset option on the System Functions menu.

Date/Time Transmission:Error is recorded when a date-and-time transmission
results in a checksum failure. Each failure posts a separate message. Therefore, if
the Communications Processor makes five transmissions before succeeding, four error
messages appear in the Event Log, followed by a
Date/Time Transmission:OK
message marking the success.

Date/Time Transmission:OK is recorded when a date-and-time transmission
succeeds.

Date/Time Transmission:Timeout is recorded when a date-and-time transmission
times out without receiving an Analyzer Processor response. Each timeout posts a
separate message. Therefore, if the Communications Processor makes five
transmissions before the Analyzer Processor responds, four timeout messages appear
in the Event Log, followed by a
Date/Time Transmission:OK message marking the
success

Excep. Train Stored is recorded each time the system scans and records a passing
exception train. This entry is recorded just before the Train Stored entry for the same
train is recorded.

Incoming Train Data: Re-Requested is recorded each time processor-B's (aka
Communications Processor's) checksum comparison fails and it asks processor-A (aka
Analyzer Processor) to repeat the train data transmission.

Rebroadcast Request is recorded when the system recognizes and handles a
rebroadcast request.
