Abstract

A weld controller is coupled to a communications network which has an operator interface unit for monitoring and controlling the weld controller and other weld controllers on the network. A common database in the operator interface unit is accessible across the communication network by the weld controller regardless of the data structure of the database. The weld controller can use the database to obtain different weld schedules, duplicate its own weld schedule to provide for easy replacement, and as a data storage for its operating parameters and values. The weld controller has a dual communications port that allows for a variety of operator interface configurations. Data from weld controller can be accessed by the operator interface controller based upon the weld controller's individual data structure and type through embedded objects resident in the operator interface's operating system and program. The data can then be displayed, edited, and stored by any data entry device that is capable of executing the operator interface's program.
