Abstract
Abstract A method of operating a computer to produce control software for a hydraulic system is provided. The hydraulic system includes a pump, at least one valve, a motor and an electronic controller. The method includes the steps of defining a set of valve features of the electronic controller as a function of user input; and producing control software to operate the controller as specified by said set of valve features.
