Ethernet: internal and external data flow
The two ECDIS share same sensor data information. Serial data is analysed and
•
broadcasted on the LAN and therefore the other ECDIS workstation can use the same
sensor input data.
Routes are usually planned on the Planning station and then transferred to the
•
Monitoring station via Ethernet.
The Monitoring station is in charge of active route and waypoint. Information about the
•
active route and waypoint is sent to the Planning station via Ethernet.
Ship's settings and Safety parameters are synchronized on the network. The ship's
•
settings and safety parameters can be adjusted on the Planning station and then the
parameters will be updated on all Planning stations for a while.
Alarm acknowledgement is also synchronized. When an alarm is acknowledged on the
•
monitoring station it is also acknowledged on other planning stations.
Chart databases on both ECDIS stations can be updated in two different ways:
The update procedure can be run twice on both workstations.
•
The update procedure is run once and the updated chart database transferred to the
•
other workstation via Ethernet.
