Title: Welding-type system with network and multiple level messaging betweencomponents

Abstract: A method and apparatus for providing welding-type power including a sourceof welding-type power connected to a controller is disclosed. Thecontroller includes a controller network module with a controller multiplelevel message module. A welding-type device includes a device networkmodule with a device multiple level message module. A network isoperatively connected to the network modules, and is capable of sending aplurality of multiple level messages. A welding peripheral and/or a secondsource of power has a network module with a multiple level module and isconnected to the network. The multiple level message includes anidentifier portion and a data portion, and the data portion can include apointer portion and a value portion in various alternatives. Thecomponents may have memory connected to the multiple level messagemodules, and store common message decoding data therein so that they haveshared knowledge for decoding the pointer portions and data portions. Thecommon data can be the same in all devices.
