COMMUNICATION SYSTEM FOR PROCESS FIELD DEVICE

摘要

A field device (102) for use in an industrial process, includes a process interface element (108) configured to measure or control a process variable. Communication circuitry (156) is configured to communicate with another location. A communication system is configured to provide communications between at least two components in the field device (102). A signal inverter (220) couples an inverted signal from the communication system (192) to other circuitry to thereby reduce interference received by the other circuitry.
