56 - Communications (cont'd)
Note: if the receiver option is programmed as Dual then a successful transmission must be made to both
primary and secondary to be considered a successful transmission.
07 = Line Fail
The line fail option controls which Ethernet connections are monitored. The Ethernet module can be pro-
grammed to monitor both the network availability and the programmed transmission paths between the
Ethernet module and receiver applications.
Line fail events (whether network or transmission path) must be present for the time programmed in parameter
51.68 before the event is activated. If a line fail is present and an attempt is made to set the system within
parameter 51.68 delay period, the line fail will immediately be logged and indicated.
1 = Network
This option monitors the connection between the Ethernet module and the local network.
0 = Off
If programmed to off, the connection between the Ethernet module and local network will not be monitored. If
the local network is not available or the Ethernet module is disconnected, no line fail will be indicated.
1 = Available
If programmed as available then the connection between the Ethernet module and the local Ethernet network
is monitored. If the Ethernet module is disconnected from the network or the local network is not available a
Line Fail event will be activated at the panel. The Line Fail event logged will indicate that the Line Fail was as
a result of a network failure.
2 = Signal Path
This option determines which signalling paths, will be monitored by the Ethernet module. Monitoring is
achieved by transmission of a path supervision signal (heartbeat) between the receiver application and the
Ethernet module. The Ethernet module must receive a path supervision signal at least as often as the frequency
programmed in option 56.4.2.7 (Alarm Reporting Heartbeat). If the signal is not received a line fail condition
will become present. The line fail event will indicate the path which failed and the destination IP address of that
path.
NOTE: If groups are enabled a failure on the primary path will not provide specific IP information.
Options are available to select specific paths or all paths.
1 = Primary
When selected the Ethernet module will only monitor the primary transmission path. All other transmission
paths will not be monitored.
2 = Secondary
When selected the Ethernet module will only monitor the secondary transmission path. All other transmission
paths will not be monitored.
3 = Alarm Mon.
When selected the Ethernet module will only monitor the Alarm Mon. transmission path. All other transmission
paths will not be monitored.
