Autonomous Message Syntax
Autonomous messages are used to report alarms, events, and reports. The format is the same as the full response except the identification of output is replaced by:
<ALMCDE>^<ATAG>^<output code> cr lf
1.Alarm Codes (ALMCDE):
•*C — Critical alarm
•** — Major alarm
•*^ — Minor alarm
•AA — Automatic message
2.ATAG is the autonomously generated correlation tag that the user can use to see if any spontaneous outputs have been missed by checking for omissions in the sequence of messages received. It starts with a value of one (l) and increments until the system is initialized again. Range is from 1 to 65535. When 65535 is reached, the value returns to l.
3.The output code identifies the nature of the output message. Values for the output code are: {REPT ALM REPT EVT REPT INITZN REPT STAT }. The output code may have a modifier [ { T1 EQPT } ]. Refer to individual message syntax descriptions.
•REPT ALM — Report alarm
•REPT EVT — Report event
•REPT INITZN — Report initialization of NE
•REPT STAT — Report status
Autonomous Messages
Autonomous messages are used to report information that is not a direct response to a specific command. Autonomous messages are:
•REPT ALM — Report alarm
•REPT EVT — Report event
•REPT INITZN — Report initialization
•REPT STAT — Report status
