Patent number: 7930042Abstract: A redundant fieldbus redundant system includes two independent conditioned power modules which automatically detect cable faults, such as short or open circuits on both the host and field sides of the network. The power modules are interfaced directly on one side to the primary and backup H1 cards of the host system, and are directly interfaced on the other side to an automatically terminating network device coupler module which provides connections to field devices. The redundant fieldbus system provides power and communications in a parallel physical configuration between the host system and the field devices irrespective of any single point failure in the network. In case of a fault, the redundant fieldbus system automatically eliminates the faulty section of the network, switches power and communications to the healthy portion of the network and terminates the network for signal integrity.Type: GrantFiled: November 17, 2008Date of Patent: April 19, 2011Assignee: Moore Industries International, Inc.Inventor: Hassan M.

Patent number: 7797061Abstract: A redundant fieldbus system provides power and communications in a parallel physical configuration between the host system and attached field devices irrespective of any single point failure in the network. In case of a fault, the redundant fieldbus system automatically eliminates the faulty section of the network, switches power and communications to the healthy portion of the network and terminates the network for signal integrity. A device coupler for the system may include a fault detector coupled to an auto-termination circuit that terminates a fieldbus cable when a fault is detected. The device coupler may include fault detection and isolation coupled to each set of spur terminals used to connect field devices to the device coupler. A field device for the system may include circuitry for deselecting a faulty cable while maintaining connection to a healthy cable.Type: GrantFiled: November 17, 2008Date of Patent: September 14, 2010Assignee: Moore Industries International, Inc.Inventor: Hassan M.

Patent number: 7633733Abstract: A power supply adapted to provide power for one or more field devices over a protocol bus based network, such as a fieldbus network, which includes an oscillator circuit and a power control switch mounted at the output of a conditioned power supply. The oscillator circuit is adapted to detect a cable fault such as a short circuit. When a cable fault is detected, the oscillator circuit sends a signal to the power control switch to stop the power supply from feeding current to the network and to activate an alarm signal to alert a host of the cable fault.Type: GrantFiled: August 18, 2005Date of Patent: December 15, 2009Assignee: Moore Industries International, Inc.Inventor: Hassan M.
