If Controller A (the active controller) fails
:
1.
Controller B will detect the loss of controller A, will automatically switch to run as the
active controller and configure itself with the active IP address X.
2.
The control system will detect a momentary loss of connection to IP address X as
controller A fails and will then re-establish its connection to IP address X (now
controller B which is active).
3.
In this instance as controller A has failed it will not start back up and controller
redundancy will be lost. Controller A must be replaced with a working controller
running with the same settings as the failed controller.
14.3.3 Nucleus2 2464/2463 Single Active/Idle IP Address Configuration
1.
The IP address settings are stored in the controller Config.XML file. They are shown
as highlighted text in the Config.xml extract below). The existing controller Config.xml
file must be edited using an XML editor. The same Config.xml file should be used on
both controllers.

a
<Config/IP/Adapter/Address>
Configures the active IP address.
b
<Config/IP/Adapter/UseRepAddressWhenIdle>
Configures replication address usage
True
- Address used as the idle IP address and as the data replication address
False
- Address used for controller data replication (treated as
False
if not
defined).
c
<Config/Replication/Address>
Configures the idle/replication IP address depending on the true/false setting
above.
d
<Config/FeatureFlags/AutoChangeOverIfNoNetworkTime>
Configures the time, in seconds, that active controller will stay active after it loses
its Ethernet connection. When this time has elapsed the active controller will go
idle and the idle controller will go active. A setting of -1 will disable the feature but
this is not recommended.
2.
See the Sirius 800 Maintenance & Upgrade manual for details on updating the
Config.xml file using a USB memory stick.
(Advanced Controller Functions, Controller Housekeeping,
Updating Config.xml file.)
Note:
If controller B was active and then failed the same process would happen but controller A
would go active and configure itself with the active IP address X.
