System, methods, and bus controllers for creating and event trigger on a network bus
First Claim
1. A system for monitoring an event of interest via a network bus, wherein said system comprises:
- a bus controller in electrical communication with the network bus for controlling communications on the network bus; and
at least one first network device in electrical communication with the network bus for indicating that the event of interest has occurred, wherein said bus controller transmits an event command via the network bus commanding said first network device to indicate when the event of interest has occurred, and wherein said first network device, upon determining that the event has occurred, transmits an indication on the network bus.

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.

9. A method for monitoring an event of interest via a network bus, wherein said method comprises the steps of:
-
transmitting an event command from a bus controller that controls communications on the network bus to at least a first network device via the network bus commanding the first network device to indicate when the event of interest has occurred;
determining via the first network device that the event of interest has occurred; and
providing an indication on the network bus. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

21. A system for monitoring an event of interest in a network system, wherein said system comprises:
-
a network bus for transporting all communications in the network system;
a bus controller in electrical communication with the network bus for controlling communications on the network bus;
at least one first network device in electrical communication with the network bus for indicating that the event of interest has occurred; and
at least one second network device for performing an associated action based on when the event of interest has occurred, wherein said bus controller transmits an event command via the network bus commanding said first network device to indicate when the event of interest has occurred, wherein said first network device, upon determining that the event has occurred, transmits an indication on the network bus, and wherein said second network device performs the associated action based on when the event of interest occurred. - View Dependent Claims (22, 23, 24)
