Appendix A - Operational Functions specific to
Multi-node and Client/Server Systems
The following operational function is specific to a multi-node system.

System In Control
The following operational function applies to a multi-node system and
Client/Server Radar (CSR) system.

Database Synchronization
Station In Control
Station In Control (SIC) is an optional feature, enabled at commissioning,
where a more secure system of control is required on a multi-node system.
The feature enables critical system control functions to be accessed only
from one or more designated nodes.
When SIC is configured, each node is assigned to one of the following
groups:

Always in Control

Never in Control
Nodes that are configured to be in the Never in Control group are never in
control unless every node from the other group is unavailable, see
`Automatic Transfer of Control' below.
A SIC node may take control over any of the following SIC functions:

Acknowledge alerts.

Turn on/off the track control feature or make changes to track
control parameters.

Change the look-ahead range, safety depth, and safety height.

Control whether safety checking Cautions can raise an alert.

Change manual sensor values.

Change the sensor source for any sensor.

Turn on/off the speed control or make changes to speed control
parameters.

Start or stop the execution of all types of route plans.

Change the current active chart database.

Change the active Mariner Object layer, or modify the Mariner
Objects that are tied only to geographic locations.
