HANDHELD FIELD MAINTENANCE TOOL WITH PROCESS COMMUNICATION TUNNEL

摘要

A method (150) of interacting with a process control system is provided. The method (150) includes bringing a mobile electronic device into physical proximity of a field device (152). The mobile electronic device is coupled to a digital process communication channel of the field device (154). A client software application is initiated on the mobile electronic device (156). The digital process communication channel is used to communicatively couple the client software application to a host application remote from both the mobile electronic device and the field device (158).
