ABSTRACT:
The present invention provides systems, methods, and bus controllers (12) for monitoring an event of interest via a network bus (14) and creating an asynchronous event trigger on the network bus indicating that the event occurred. Importantly, the systems, methods, and bus controllers (12) of the present invention use either one or several network devices (16, 18) that are connected to the network bus (14) and monitor the occurrence of an event of interest. These network devices (16, 18) are configure through commands from the bus controller (12) to indicate on the network bus (14) typically by a pulse signal, when the event of interest has occurred. The indication from the network device (16, 18) that the event has occurred is used by the bus controller (12) and other network devices (16, 18, 20) on the network bus (14) to configure timing for commands or to perform desired actions in synchronization with the occurrence of the event of interest.
