Provides parametric data for a specific DC Source, indicated by the instance field. Used primarily by display or instrumentation devices, but may also be used by battery management controlsĪny device capable of charging a battery may transmit this message. Provides parametric data for a specific battery, indicated by the battery instance field. Used primarily by display or instrumentation devices.
For example the fluid instance may be the level of fuel in a tank or the level of water in the bilge. Universal commands to multiple banks of two-state devices.Īny device with an AC Input may transmit this messageĪny device with an AC Output may transmit this message.įluid Level contains an instance number, type of fluid, level of fluid, and tank capacity. Universal status report for multiple banks of two-state indicators. Provides identification information and rated engine speed for the engine indicated by the engine instance field. This message would normally be broadcasted periodically to provide information for instrumentation or control functions. Used to provide the operational state and internal operating parameters of a specific transmission, indicated by the transmission instance field. This message would normally be broadcasted periodically to provide information for instrumentation or control functions.ġ27493 - Transmission Parameters, Dynamic Used to provide real-time operational data and status relevant to a specific engine, indicated by the engine instance field. The first field provides information as to which engine.
Provides data with a high update rate for a specific engine in a single frame message. The quality of service and age of service are provided to enable recipients to determine an appropriate level of service if multiple transmissions exist. The message contains a sequence number to allow synchronization of other messages such as Heading or Course over Ground. This would typically be used for vessel stabilization, vessel control and onboard platform stabilization. This PGN provides a single transmission that describes the position of a vessel relative to both horizontal and vertical planes. Rate of Turn is the rate of change of the Heading. If the sensor value is Magnetic, the deviation field can be used to produce a Magnetic heading, and the variation field can be used to correct the Magnetic heading to produce a True heading. Heading sensor value with a flag for True or Magnetic. Rudder order command in direction or angle with current rudder angle reading. Allows for navigational (remote) control of a heading control system and direct rudder control. Sends commands to, and receives data from, heading control systems. Provides product information onto the network that could be important for determining quality of data coming from this product.įree-form alphanumeric fields describing the installation (e.g., starboard engine room location) of the device and installation notes (e.g., calibration data)
To provide synchronism for measurement data The purpose of this PGN is twofold: To provide a regular transmission of UTC time and date. The message will be a Transmit or Receive PGN List group function. The Transmit / Receive PGN List Group type of function is defined by first field. The message will be a Request, Command, or Acknowledge Group Function.ġ26464 - Receive/Transmit PGN's group function The Request / Command / Acknowledge Group type of function is defined by first field. Local geodetic datum and datum offsets from a reference datum.
