7.9.12 DEIF network redundancy broken
This alarm applies to the DEIF network connection between the controller PCM modules. The alarm is activated when there is no
redundant communication between the controllers. This alarm is based on the single-line diagram and the application
communication. That is, all of the controllers in the network must be included in the single-line diagram.
Configure the alarm parameters under Configure > Parameters > Communication > DEIF network > DEIF network redundancy
broken. This alarm action is always Warning.
Table 7.36
Ethernet redundancy broken default parameters
Parameter Range Default
Enable Not enabled, Enabled Enabled
INFO
This alarm must either be Enabled for all the controllers in the system, or Not enabled for all the controllers in the system.
7.9.13 Single-line missing/none active
This alarm communicates that the single-line diagram cannot be read from the controller, or that no single-line diagram is configured
for the controller.
The alarm is always enabled and the action is Warning. The alarm parameters are not visible in PICUS. When the alarm is
activated, the controller is forced under switchboard control.
7.9.14 Different single-line configurations
This alarm communicates that different single-line diagrams are present on one or more controllers in the system.
This alarm is activated when a single-line diagram is written to a controller, but not Broadcast to the remaining controllers. The alarm
is always enabled, and the action is Warning. The alarm also forces the controller under switchboard control. The alarm parameters
are not visible in PICUS.
7.9.15 Controller not part of system
This alarm communicates that the controller has a Controller ID that is not included in the single-line diagram. Check or configure
the system under Configure > Single-line.
The alarm is always Enabled, and the action is Warning. The controller will also be forced under switchboard control. The alarm
parameters are not visible in PICUS.
7.9.16 Controller type mismatch
This alarm communicates when a controller's type does not match the controller type with its Controller ID in the single-line diagram.
This alarm is activated when the Controller ID is assigned to an incorrect controller type in the single-line diagram, and the single-
line diagram is written to the controller. The controller is also forced under switchboard control. The alarm parameters are not visible
in PICUS.
Controller type mismatch example
An EMERGENCY genset controller has Controller ID 1, but on the single-line diagram Controller ID 1 is assigned to a BUS
TIE breaker controller. The alarm is activated when the single-line diagram is written to the controller.
