ABSTRACT:
A control arrangement for a multifunction appliance such as a cooking appliance wherein the control activity is distributed among a plurality of microprocessor based control circuits. In the exemplary embodiment each control circuit is associated with a different function of the appliance. The circuits are physically separated from one another and communicate on data bus lines. Due to the high transient conditions in such an appliance, the communications are in accordance with a redundant protocol to substantially eliminate erroneous data communication. The data bus protocol is devised such that deletion, addition and replacement of control circuits in a system, even to the point of substituting a circuit containing a different type of processor, is possible.
