Abstract
A method and apparatus for controlling a work function, such as, for example, welding, requiring the control of at least one parameter according to a predetermined sequence, the apparatus including at least one work station where the work function is carried out, a slave controller associated with the work station for controlling the work function, at least one interface operably connected to the slave controller capable of receiving and storing information for a first parameter of the work function and preventing transmission of the parameter information to the slave controller until being probed by the slave controller, and a master controller operably connected to the interface to transmit thereto the parameter information, and the master controller being further operably connected to the slave controller to cause the slave controller to probe the interface to allow transmission of the parameter information to the slave controller. In one embodiment, the information for a second parameter is transmitted from the master controller to the control portion of the slave controller so that such parameter information can be modified, if desired, while the work function is being carried out.
