- I/O input/output
- Monitoring systems receive signals indicative of process measurements and monitor various aspects of a process based on the received signals. Monitoring systems can be adapted to compare measured process data against pre-determined limits and to initiate an action (such as generating an alarm signal) if the limit is exceeded.
- a process controller of a monitoring and control system can use the measurements and other information to monitor a process and to implement a control routine. The process controller can generate control signals, which can be sent over buses or other communication paths or channels via an analog or digital I/O device to the field devices to control the operation of a particular process.
- Various communication protocols were developed to enable controllers and field devices from different manufacturers to exchange data.
- Various communication protocols include, for example, HART ® , PROFIBUS ® , actuator sensor interface ( "AS-Interface” ), WORLDFIP ® , Device- Net ® , CAN, and FOUNDATIONTM FIELDBUS (hereinafter "fieldbus”) protocols.

- FIG. 3 is a simplified cutaway partially exploded view of pressure transmitter in accordance with another embodiment of the present invention.
- FIG. 4 is a block diagram of a feature board for use with a field device in accordance with an embodiment of the present invention.
- FIG. 1 illustrates a simplified block diagram of a process control or monitoring system 100 having a plurality of field devices 108A-110N, where any number of field devices can be used.
- Process network 106 is comprised of a control or monitoring system 118 with an operator interface 120 (such as a user workstation or computer) , which can be coupled through a Power over Ethernet injector (POE injector) 122 via Ethernet cabling 124 to one or more of field devices 1082A- HON.
- POE injector 122 receives power from power supply 123 and places a voltage potential on one or more unused pairs of wires within the Ethernet cabling 124.
- POE injector 122 can place a voltage potential on the same pairs of wires that carry the Ethernet signal. Further, injector 122 may place a voltage potential on one or more unused pairs as well as one or more data pairs.
- Each field device 108A-110N is preferably- adapted to derive operating power from the voltage potential on the Ethernet cabling 124. Power can be delivered on the same cable 124 as Ethernet communications.
- the Ethernet cabling 124 can be, for example, a CAT5E cable.

- the Power over Ethernet standard (IEEE 802.3af) allows up to 48-volts and up to 35OmA to be carried by the Ethernet cabling 124.
- the PoE standard makes it possible to operate a number of field devices.
- Ethernet cabling 124 will generally supply 48-volts and 35OmA of current for attached field devices . With lower power field devices, the number of field devices can be increased even further. Thus, a large number of process variables can be delivered down the same cable assembly as the power supply.
- Ethernet cable 124 By delivering power through the Ethernet cable 124, one cable pair (e.g. power cabling) can be eliminated, and installation can be made simpler. In many installations, Ethernet ports and cabling may already be in place, allowing for easy installation. Additionally, newer PoE standards, in the near future, may allow for higher voltage and/or higher current delivery, thereby allowing for power delivery to more segments or networks and more field devices . In general, by utilizing Ethernet-type communications protocols, control and/or monitoring functions can be accessed, for example, via a hypertext markup language (web-page) interface, using a standard Internet browser.
- web-page hypertext markup language
- the field devices may be accessible by any addressing means, including Transmission Control Protocol/Internet Protocol (TCP/IP) addressing, Medium Access Control (MAC) addressing, Network Layer addressing, or any other electronic addressing means supported by an Internet browser, for example.

- the MAC address comprises two distinct identifiers (IDs) .
- the first identifier is a unique 24-bit manufacturer ID
- the second identifier is a 24-bit (or 40-bit) extension ID (or Board ID) , which is assigned by the manufacturer.
- the Board ID identifies the specific NIC, which is specific to the device.
- the destination and source MAC names are contained in the header and are used by network devices to filter and forward packets .
- Ethernet packets are variable length units in which information can be transmitted over an Ethernet network.
- Each Ethernet packet includes a synchronization preamble, a destination address
- the destination address is a device specific address corresponding to a particular interface module 102.
- the data field contains an address specific to the particular field device.
- FIG. 2 is a simplified cutaway partially- exploded view of pressure transmitter 214, which is one example of a field device .
- Other examples of field devices include valves, actuators, controllers, alarm modules, diagnostic devices, et cetera.
- Many field devices include, or are coupled to, a transducer which interacts with the process.
- a transducer may be a sensor for sensing a characteristic of the process, or a valve controller or solenoid for effecting some change in the process.
- Pressure transmitter 214 couples to two- wire process control loop 216 and includes transmitter housing 62.
- Housing 262 includes end caps 270 and 272 which can be screwed into housing 262. When attached, end caps 270 and 272 provide an intrinsically safe enclosure for circuitry within transmitter 260.
- Process control loop 216 couples to terminals 256 carried on terminal board 258.

- Field device circuit 268 is configured to communicate with measurement circuit 266 to determine the process variable value sensed by sensor 264, and to communicate the value over process communication loop 216.
- Feature board 222 couples to field device circuitry 268 and may, in some embodiments, couples to process control loop 216.
- a feature board is any circuitry, module or group of components that is configured to couple to an interface and provide a feature.
- Feature boards for field devices are known to provide wireless communication, as well as local operator interfaces .
- feature board 222 is configured to operate in accordance with the PoE protocol, and allow interaction with field device 214 over the PoE communication link.
- Embodiments of the present invention can also be practiced with integral PoE circuitry, but the utilization of a feature board is important in that it allows already-installed, legacy field devices, to be provided with this new communications ability.
- Transmitter 314 is similar to transmitter 214, and like components are numbered similarly. Unlike transmitter 214, transmitter 314 does not couple directly to a process communication loop. Instead, feature board 222 operably couples transmitter 314 to PoE network connection 124. Depending on the configuration of feature board 222, transmitter 314 may be wholly powered by energy received from feature board 222 over PoE network connection 124.

- field devices that are not otherwise adapted for communication in accordance with the PoE protocol can communicate in their native protocol with feature board 222, which can translate, or otherwise adapt, such communication for transmission over PoE network 124.
- FIG. 4 is a block diagram of a feature board for use with a field device in accordance with an embodiment of the present invention.
- Feature board 222 includes Ethernet connector 400 that is configured to couple to an Ethernet network in accordance with the PoE standard.
- connector 400 is in the form of a known RJ-45 connector, but may take other suitable forms in order to facilitate use in industrial environments. Examples of adaptations of connector 400 include material selection, connector size, retention mechanisms or latches, or other suitable criteria.
- Connector 400 is coupled to Ethernet physical layer module 402, and PoE power module 404. Ethernet physical layers or cores are known, and provide the low-level signal interactions on the Ethernet media.
- Power module 404 is coupled to connector 400 allowing feature board 222 to receive electrical power from the Ethernet connection in accordance with the PoE standard. As such, power module may draw up to 350 mA at 48 volts, if need be.
- Power module 404 is coupled to Ethernet physical layer module 402, controller 406, and field device I/O interface module 408 to supply all required operating
- Controller 406 is preferably a microprocessor and may include memory such a read- only memory (ROM) , random access memory (RAM) . Additionally, feature board 222 may include additional memory (shown in phantom at 410) that is coupled to controller 406. The additional memory can be useful to allow controller 406 to perform more sophisticated functions. For example, controller 406 may execute instructions stored therein, or within memory 410, to perform any of the following functions: web server; ftp server; secure shell (ssh) server. Moreover, controller 406 and memory 410 may even comprise an embedded information server capable of running an operating system. An example of such a system is sold under the trade designation Etherstix, available from Gumstix Inc, of Portola Valley, California.
- Etherstix available from Gumstix Inc, of Portola Valley, California.
- memory 410 can be used to store information about a number of commercially available field devices, such that when feature board 222 is ultimately coupled to a particular field device, the feature board can simply be told which particular field device it is coupled to, and then access further information regarding that particular device within memory 410 in order to determine how to interact with the field device.
- the manner in which feature board 222 is informed of the field device can take any suitable form including setting jumpers on feature board 222, sending commands to feature board 222 through the Ethernet network; and/or accessing a rudimentary operator interface (not shown) on feature board 222.
- Controller 406 is coupled to field device I/O interface module 408, which is coupled to field device connector 412.
- Connector 412 is preferably configured to physically couple to a field device in a manner that known feature boards currently coupled to field devices. However, embodiments of the present invention can also be practice where connector 412 is any suitable connection including simply coupling feature board 222 to the process communication loop terminals of a field device using wires or the like.
- Field device I/O interface module 408 is configured to interact with the field device, attached to feature board 222 through connector 412, using any suitable process communication protocol. Thus, if the field device is only able to provide a process variable value indication by setting a current between 4 and 20 mA, module 408 may generate a suitable current for the field device. Preferably, module 408 provides energization current to the attached field device through connector 412. For example, a 4-20 mA pressure transmitter may receive its operating current from feature board 222 through connector 412.

- feature board 222 can be instructed by a technician to engage a particular protocol-specific module .
- Feature board 222 may include additional communications modules, such as module 422 illustrated in phantom.
- Module 422 may allow additional communication methods, such as wireless communication with feature board 222, and thus field device 412.
- Communication module 422 also derives all of its operating power through PoE power module 404, and allows or facilitates communication in accordance with a different communication protocol, such as the known Bluetooth communication protocol, IEEE 802.11b wireless access points and wireless networking devices built by Linksys of Irvine, California) , cellular or digital networking technologies (such as Microburst ® by Aeris Communications Inc.
- GSM Global System for Mobile Communications
