Encoding Notes

Tide Information

The tide value only contains a value if Qinsy is actively using a tide observation for the height observation. If this is the case the tide status will be set to 'valid'.

Position Information

The position information as outputted is using the survey projection and vertical chart datum as its horizontal & vertical references.

Work Spud Information

The work spud information is computed using the position of the spud node as selected in the 'Dredging Parameters - Positioning' dialog in the Database Setup Program.

Project Grid Convergence

The convergence field uses the following convention: Convergence = True bearing - Grid bearing.

Spare Fields

The spare fields are currently not used and therefore remain 0.0.

System Interfacing

The driver is normally connected to the DigiSys system using a network connection and uses the UDP protocol as means of communication. The driver is redundancy enabled.
This means that the driver will adhere to the settings as found in the 'Controller - Output Driver Settings' dialog as shown below:

System Configuration

The DigiSys system should be configured to use the same UDP port as set in the Qinsy template database.

Qinsy Configuration

Database setup
