A control system for an appliance including a plurality of peripheral devices, said control system comprising:

• a controller;
• a communications bus coupled to the plurality of peripheral devices and coupled to said controller, said communications bus including a diagnostic communications port and a collision detection system, said controller configured to:
• receive data from the peripheral devices over said communications bus;
• and
• transmit control operations to the peripheral devices based on said data,
• wherein said plurality of peripheral devices are each configured to be at least one of a master and a slave, and
• wherein said master is configured to send a command packet to request an action from a slave, and
• wherein said command packet comprises an STX, an address, a packet length, a command, a data byte, a CRC, and an ETX.
