7.3. Alarm SNVT
e monitoring application also has an Alarm2 SNVT type 164. is alarm is propagated
whenever a fault is detected or cleared. e fields used in the Alarm2 SNVT are as follows:
alarm_type is set to 1 whenever a diagnostic detects a fault. alarm_type is set to 0 when all faults
have cleared.
description is set to an ASCII text description of the associated fault state whether IP or LON
or both are cleared.

7.4. Status Report UNVT
e monitoring application has a status report UNVT that includes some extra information that
would not fit in the Status SNVT. e status report UNVT is scheduled for propagation whenever
one of its fields is updated. It will only be propagated if bound or polled. e c structure for the
UNVT is as follows:
typedef struct
{
unsigned char Status;
char reserved[3];
uint32 totalArbs;
uint32 totalFailuresIP;
uint32 totalFailuresLON;
uint32 totalFaultsIP;
uint32 totalFaultsLON;
uint32 secsSinceClear; // seconds
uint16 forwardRate; // packets per second
char reserved[2];
} UNVTStatusType;
e fields are as follows:
Status
is an 8 bit number. e bit definitions are given in Table 1. It is the same information
reported in the Status SNVT reserved field.
totalArbs is the total number of active state arbitrations since the last time the statistics were
cleared.
totalFailuresIP is the total number monitoring packet failures detected by this device of the IP
interface since the statistics were cleared.
totalFailuresLON
is the total number of monitoring packet failures detected by this device of
the LON interface since the statistics were cleared.
totalFaultsIP
is the total number of diagnostic faults detected by this device of the IP interface
since the statistics were cleared.
totalFaultsLON
is the total number of diagnostic faults detected by this device of the LON
interface since the statistics were cleared.
