A two-wire field-mounted process device with multiple isolated channels includes a channel that can be an input channel or an output channel. The given input or output channel can couple to multiple sensors or actuators, respectively. The process device is wholly powered by the two-wire process control loop. The process device includes a controller adapted to measure one or more characteristics of sensors coupled to an input channel and to control actuators coupled to an output channel. The controller can be further adapted to execute a user generated control algorithm relating process input information with process output commands. The process device also includes a loop communicator that is adapted to communicate over the two-wire loop.

G06F011/30
US Classification:
702183, 700117
Abstract:
A field device includes diagnostic circuitry adapted to measure a characteristic related to a process control and measurement system. The measured characteristic is used to provide a diagnostic output indicative of a condition of the process control and measurement system. The measured characteristic can be provided to a diagnostic module that operates upon the measured characteristic to predict, or otherwise model, a condition of the process control and measurement system.

Abstract:
Infrared radiation from a plurality of locations associated with a process is measured by a field device, which includes a plurality of input channels, a plurality of IR sensors, and a data processor. The infrared radiation from the locations associated with the process is received by the input channels and the intensity of the infrared radiation is measured by the IR sensors to produce representative sensor signals. The data processor produces an output as a function of selected sensor signals.
Field-Mounted Process Device With Programmable Digital/Analog Interface
Embodiments of the present invention generally provide a field-mountable process device that receives digital information from one or more process devices, and provides an associated analog output. Embodiments of the present invention include providing a wireless interface to the field-mounted process device such that configuration and/or diagnostic information can be communicated between the field-mounted process device and one or more additional devices. In some embodiments, the field-mounted process device can be completely powered by the digital process communication loop to which it is coupled. Finally, embodiments of the present invention also include generating and storing within the field-mounted process device a mapping between one or more field devices communicating in accordance with a digital process communication protocol and an analog output of the field-mounted process device.

Abstract:
A diagnostic device for use in a industrial process includes monitoring electronics or diagnostic circuitry configured to diagnose or identify a condition or other occurrence in the industrial process. The system can be implemented in a process device such as a flowmeter, and in one example an acoustic flowmeter. A transducer can also be used and a frequency response, such as resonant frequency, can be observed.
A process control system utilizes wireless transceivers to divorce the field devices from traditional wired network topologies. By providing field devices with wireless transceivers and shared wireless transceivers for adapting wired field devices, the field device network may be adapted to any number of network topologies without concern for additional wiring costs. Specifically, a power supply can be provided for each field device or for groups of field devices, as needed. Thus, the entire network can receive power from a single power bus, without expensive power filtering. In addition, the network can be a hybrid in which part of the information is transmitted and received over wired lines and part is transmitted and received over wireless communications.

Abstract:
A distributed control system has a plurality of distributed field devices, each of which contains a transducer and a wireless transceiver. The distributed control system includes a base station transceiver, a database and a virtual transmitter application in communication with the database. Each field device transmits and receives data via wireless signals between the communications boards and the base station. The data is stored in the database for later retrieval and evaluation by the virtual transmitter application. The deployed field device senses information and transmits the sensed information wirelessly to a base station. The sensed information is stored in memory on a computer system, and programmatically groomed to provide a measurement value, upon request by a user.
