A communications network has an operator interface system for monitoring and controlling controllers utilizing any known control strategy. A common database is accessible across the communication network of controllers regardless of each controllers dissimilar data structure. The operator interface provides an apparatus for displaying, storing, and editing data obtained from the network. Data from each controller can be accessed by a master device based upon the controller's individual data structure and type through embedded objects resident in the master device'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 master's program.

Common database system for a communication system

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 time of day clock provides a chronological reference to tag weld current and voltage data and other data when it occurs for storage in its memory which is also accessible by the operator interface unit for storing in said system database. A memo pad in the weld controller is also accessible to the network for storing data for diagnostic purposes, said data including faults, events, and other operational data. The data can then be displayed, edited, and stored by the operator interface's program.

Diagnostic system for a weld controller

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.
