  • Welding-type system with network and multiple level messaging between components
    Patent number: 6670579
    Abstract: A method and apparatus for providing welding-type power including a source of welding-type power connected to a controller is disclosed. The controller includes a controller network module with a controller multiple level message module. A welding-type device includes a device network module with a device multiple level message module. A network is operatively connected to the network modules, and is capable of sending a plurality of multiple level messages. A welding peripheral and/or a second source of power has a network module with a multiple level module and is connected to the network. The multiple level message includes an identifier portion and a data portion, and the data portion can include a pointer portion and a value portion in various alternatives. The components may have memory connected to the multiple level message modules, and store common message decoding data therein so that they have shared knowledge for decoding the pointer portions and data portions.
