COMMUNICATION SYSTEM FOR PROCESS FIELD DEVICE

摘要

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