Machine controller allowing concurrent functions

A method for controlling an agricultural machine comprising an input module being configured to receive a command from an operator of the agricultural machine, a plurality of machine specific control modules connected to a data communication bus, each of the machine specific control modules being configured to control a different function of the agricultural machine, a field computer connected to the data communication bus, the field computer including a graphical display, the field computer being configured to communicate with the machine specific control modules to display respective functions of the agricultural machine, and a machine controller connected to the input module and the data communication bus, the method comprising:

• (a) receiving a command from the input module relating to a first function of the agricultural machine;
• (b) instructing a first machine specific control module to complete the command with respect to the first function over the data communication bus;
• and
• (c) displaying to the field computer a second function of the agricultural machine from a second machine specific control module.

An agricultural sprayer comprising:

• a sprayer boom extending transversely relative to the agricultural sprayer;
• a joystick being configured to receive a command from an operator of the agricultural sprayer;
• a touchscreen Human Machine Interface (HMI) being configured to receive a command from an operator of the agricultural sprayer;
• a plurality of machine specific control modules connected to a data communication bus, each of the machine specific control modules being configured to control a different function of the agricultural sprayer;
• a field computer connected to the data communication bus, the field computer including a graphical display, the field computer being configured to communicate with the machine specific control modules to display respective functions of the agricultural sprayer;
• and
• a machine controller connected to the joystick, the touchscreen HMI and the data communication bus, the machine controller executing a program stored in a non-transient medium operable to:
• (a) receive a command from the joystick or the touchscreen HMI relating to a function of the agricultural sprayer;
• and
• (b) instruct a machine specific control module to complete the command with respect to the function.
