1 FIELP 48 Field-Mounted ontroller Introduction Features & enefits The need for only one wire pair to communicate with the control room reduces wiring costs ombines multiple loop components in a single package for reduced hardware and maintenance costs Improves loop accuracy by using digital technology and by eliminating data communication errors among multiple components. The ability to communicate with the controller from a remote, central location improves operations Implementation of the HRT communication protocol facilitates use with many control system devices Factory onfigured ptions (Fs) reduce configuration time for standard control strategies Flexible input options accommodate existing I/ escription The FIELP 48 Field-Mounted ontroller supports an advanced single-loop control applications, while reducing installed costs. The FIELP controller lowers hardware costs by providing multiple loop components in one package and decreases wiring costs by reducing to one the number of wire pairs needed to transmit data to a central control room. The loop components integrated within the FIELP controller are based on the proven technology of several other instruments, including the iemens ontrollers, pressure transmitters, and I/P and P/I converters. This combination allows the FIELP controller to provide an innovative, reliable controller that can be mounted directly at the process site. The FIELP controller includes a TYPE 4X (IP65) enclosure and a hazardous area design (intrinsically safe and nonincendive) to allow installation at the process site. It offers several choices of direct process inputs, optional pneumatic or thermocouple/rt inputs, and an optional pneumatic output, all of which are in addition to the standard complement of 4-0 m inputs and discrete I/. The FIELP controller also minimizes wiring costs via the HRT protocol. With HRT digital signal, the FIELP controller transmits process data to a control room over one standard wire pair, instead of the three to four wire pairs required by a typical loop. Using HRT also allows the FIELP controller to communicate with many other devices, because HRT has the largest base of any field communications protocol. The FIELP controller accommodates control strategies ranging from basic PI control to sophisticated loops, such as ratio, bias, single-station cascade, dual-loop and feed-forward control. ircuits are configured via the same function block technique employed with the Model 5 Process utomation ontroller, where the user simply selects the desired blocks, connects them, and sets parameters, such as gains and timer values. Moreover, the FIELP controller provides over 60 pre-configured function blocks containing more than 00 functions. In addition, the FIELP controller provides many preconfigured control strategies (Fs). Each F can be used as is, or customized as needed, significantly reducing configuration time for standard control requirements. The FIELP controller is configured locally or at a remote P. The station s pushbuttons allow the FIELP controller to be configured at the faceplate..8
