either interface has failed the active node will not receive any round trip monitoring packets so

it will report a failure on both interfaces. However it will only report a fault on one. In the same

event the inactive twin will report a failure on only one interface not both. The inactive will

report a fault on one interface.
Alternatively if one interface fails and then some time later the other interface fails, the initially

active twin will not diagnose the second fault. The initially inactive twin, however, will diagnose

the second fault. Therefore in order to fully characterize the failure and fault state of a

redundant pair the state of both devices must be examined. Moreover, the monitoring

application is on the LON side. In the event of an IP failure the alarm SNVT sent by the active

node may not be received by a monitor HMI on the IP side. Although the alarm is sent out both

sides, the IP side has failed so the alarm can’t propagate on the IP side and the inactive twin

may not have switched to forwarding mode in time to forward the alarm packet. Nevertheless,

the inactive device will also detect the fault and its alarm will propagate.

3.3.2. Status SNVT

The twin monitoring application has a status SNVT type 93. If bound, the status SNVT is

propagated either on a timer, or when it is updated by the monitoring application, or both, or

neither. If

propagate on update

is off and the update time is zero then the status SNVT will never

be scheduled for propagation. In this case the only way to read the status SNVT is to poll it. If

propagate on update

is off and update time is non zero then the status SNVT will propagate at an

interval specified by the update time. If

propagate on update

is on and update time is non zero

then the status SNVT will propagate both on the update time interval and anytime the status is

changed. If the update time is zero and

propagate on update

is on then the status SNVT will only

propagate when changed or updated by the monitoring application. Typically the status is

updated when the twin mode state changes.
The fields used in the status SNVT are as follows:

comm_failure

is set to 1 when there is either a monitoring failure or a diagnostic detects a fault.

comm_failure

is not set to 0 until all failures and faults have cleared.

reserved2

is set based on the system state. See the following table.

Bit values for reserve2 status byte (big endian)

Bit

Value

1 Active State, 0 Inactive State

1 Forwarding, 0 Dropping

1 Repair State, 0 Not Repair State

1 Diagnostic State, 0 Not Diagnostic State

1 IP side failure, 0 No IP side failure

1 LON side failure, 0 No LON side failure

1 IP side fault, 0 No IP side fault

1 LON side fault, 0 No LON side fault
