Device and method for monitoring a genset using a controller area network bus interface
First Claim
1. A device for monitoring and controlling a genset, said genset having an internal network over which engine data is communicated, said device comprising:
- a network interface for coupling with said internal network to receive said engine data therefrom; and
a processor in communication with said network interface that is configured to process said received engine data to thereby control and monitor the operation of said genset.

Abstract
A genset monitoring and control device that interactively monitors and can control a genset having an internal network over which engine data is communicated is implemented with a network interface for coupling with the genset'"'"'s internal network to receive engine data therefrom and pass data and commands thereover. The genset monitoring and control device'"'"'s processor uses the engine data received directly from the genset'"'"'s internal network via the network interface to control and monitor the operation of the genset. Also, the genset monitoring and control device can request various engine data from the genset'"'"'s internal network, and command new data to be collected in response to a command. The internal network is preferably a controller area network (CAN), and the engine data is preferably communicated on the CAN in the SAE J1939 messaging protocol.
