US 7844365 B2Abstract
One way to reduce the requisite wiring is by using two-wire process devices. These devices couple to the control room using a two-wire process control loop. Two-wire devices receive power from the process control loop, and communicate over the process control loop in a manner that is generally unaffected by the provision of power to the process device. Techniques for communicating over two-wires include 4–20 mA signaling, the Highway Addressable Remote Transducer (HART�) Protocol, FOUNDATION™ Fieldbus, Profibus-PA and others. Although two-wire process control systems provide wiring simplification, such systems provide a limited amount of electrical power to connected devices. For example, a device that communicates in accordance with 4–20 mA signaling must draw no more than 4 mA otherwise the device's current consumption would affect the process variable. The frugal power budget of two-wire process devices has traditionally limited the functionality that could be provided.
Loop 14 can be a two-wire process control loop. A number of two-wire process communication protocols exist for communicating on loop 14, and any suitable protocol can be used. For example, the HART� protocol, the FOUNDATION™ Fieldbus protocol, and the Profibus-PA protocol can be used with embodiments of the present invention. Loop 14 provides power to connected process devices while providing communication between the various devices.
