Carrier and backhoe control system and method

A power machine having a supporting frame, at least one hydraulically controlled function, and an operator compartment in combination with a removable attachment, comprising:

• an input control device disposed in the operator compartment and configured to generate movement signals in response to operator movement of the input control device;
• a first electronic control unit disposed on the power machine and configured to receive the movement signals from the input control device;
• a second electronic control unit disposed on the attachment and configured to receive the movement signals from the input control device and control movement of the attachment based on the movement signals;
• an actuation device disposed on the attachment remotely from the second electronic control unit and configured to receive electronic control signals from the second electronic control unit for controlling the actuation device;
• a serial communication network coupled to the first and second electronic control units configured to carry instructions between the first and second control units;
• and
• a state selection input disposed in the operator compartment to select one of at least two operational states including a first operating state and a second operating state, the first electronic control unit configured to control operation of the power machine in response to the movement signals while in the first operating state, and the second electronic control unit configured to control operation of the attachment in response to the movement signals while in the second operating state.

An implement configured to be coupled to a power machine having a frame, an operator compartment supported by the frame, and a joystick controller disposed in the operator compartment, the joystick controller configured to generate movement signals in response to operator movement of the joystick controller;

• an electronic machine control unit configured to receive the movement signals from the joystick controller, the implement comprising:
• at least one actuable device;
• an electronic implement control unit configured to be placed in communication via a serial communication network with the electronic machine control unit and capable of providing control signals to the at least one actuable device;
• and
• wherein the electronic implement control unit is configured to operate in a plurality of operating states, including a first operating state and a second operating state, wherein the electronic implement control unit is configured to control the at least one actuable device in response to given movement signals when the second operating state is active and refrain from controlling the at least one actuable device in response to the given movement signals when the first operating state is active so as to allow the electronic machine control unit to control the power machine in response to the movement signals.
