T he act al applied sit ation of Profib s and Ind strial Et hernet technology are presented, they are fit for ind st rial boilers spot w hich owes a lot of comm nication and high comm nication rate. Also thro gh combining spot cont rol facilitys act al distrib tion, they can apply the config ration modes w ith concentration or distrib tion, satisfy the craft work prod ction and ser demand at maxim m level.The system combine PLCConfig re softw are w ith ind strial control com p ter, Feed w atermin s press re of hearth and the press re of the steam a tomatic control are realized, so as to economize energy , increase profit s, promote t he constr ction of informat ion management, and improve t he competitive ability of corporation.
