Abstract
Methods and systems for detecting a state of a field asset using a packet capture agent is disclosed. A method may include capturing one or more packets transmitted on a shared bus in a field asset and determining the occurrence of a door event based at least one the one or more captured packets.
Claims21
A method, comprising:
- capturing one or more packets transmitted on a shared bus from a machine controller to at least one payment device in a field asset;
- and
- based on one or more captured packets relating to communications between the machine controller and the at least one payment device, determining the occurrence of a service door event within the field asset.
A field asset, comprising:
- a machine controller configured to function as a master of a shared bus;
- one or more payment devices coupled to the bus, wherein the machine controller transmits packets to at least one of the payment devices via the shared bus;
- a snoop agent configured to capture packets transmitted on the shared bus;
- and
- a device operable to determine the occurrence of a service door event based on the captured packets relating to communications between the machine controller and the at least one payment device.
