Abstract
An interface system for use in switchgear and motor control center applications so that communications may occur between different field devices and process control computers using different protocols and requiring different data formats. The interface system translates fieldbus protocols and data formats using a changeable communication driver module employing a description language defining pieces of data called 'telegrams.' The telegrams contain object structures related to the communication processor or protocol used by the field devices and process control computers. The system also allows for dynamic configurations given the changeable communication driver.
