	United States Patent Application: 0040148041
		The exemplary fieldbus relay arrangements 560 are coupled to the fieldbus network via the spurs 550, which may provide power to the relay arrangements and communications with the other field devices attached to the fieldbus network.
		This pressure sensing fieldbus device 780 may be used to monitor a pressure level 795, and may transmit a signal 760 to the fieldbus relay arrangement 700 when a particular predetermined alarm condition occurs.
		This transducer block 830 may be used to convert the control signal into a form suitable for controlling the motor which is connected to relay outputs 850 of a relay module 840 of the fieldbus relay arrangement 800.

	InTech: A view from the Far East
		Not only is Foundation fieldbus multivendor interoperable, it is also heterogeneously interoperable, Which means instruments on the bus have a two-part data-handling structure (logic and communications), where the communications part is common.
		For fieldbus, the next level is a virtual device model for field instruments that will allow full homogeneity of field-- based control and monitoring that integrates the communications part of an instrument with its control part.
		For the latex waste system, the PID loop controls the flow rate to the dissolved air floatation unit, pH at the mixing tank, and the air saturation vessel's level at their respective set points.
