Abstract
An electric motor addressing system and method for an agricultural implement receives, at an electronic control unit (ECU), an address claim request from each motor of a plurality of motors coupled to the ECU via a first bus. Each address claim request includes a requested bus address and a binary value corresponding to a pin connector setting associated with a harness connector of the respective motor. The system associates the binary value with a physical address for each motor without reference to the bus address and maps each bus address to the physical address.
Claims18
An electric motor addressing method for an agricultural implement, the method comprising:
- receiving, at an electronic control unit (ECU), an address claim request from each motor of a plurality of motors coupled to the ECU via a first bus, each address claim request comprising a requested bus address and a binary value corresponding to a pin connector setting associated with a harness connector of a respective motor;
- associating the binary value with a physical address for each motor without reference to the bus address;
- and
- mapping each bus address to the physical address.
An electric motor addressing system for an agricultural implement comprising:
- a wire harness comprising a plurality of connectors, each connector comprising a unique pin connector value, the wire harness providing a data bus for data communications;
- a plurality of devices coupled respectively to the plurality of connectors, each device comprising circuitry that can read the respective pin connector value and communicate the respective pin connector value over the data bus;
- an electronic control unit (ECU) coupled to the plurality of devices via the wire harness, wherein the ECU is configured to:
- receive an address claim request over the data bus from a device of the plurality, the address claim request comprising the pin connector value of the device and a bus address;
- associate the pin connector value of the device to a physical address of the device;
- map the bus address to the physical address of the device;
- and
- communicate with the device over the data bus based on the physical address.
