  • Method and apparatus for control of hydraulic systems
    Publication number: 20050144936
    Abstract: An apparatus and method for controlling hydraulic systems. The control apparatus (module) accepts a variety of input forms, and the output is user-configurable to control both sides of an attached coil. The master module is programmable via a graphical user interface defining states and conditions triggering transitions between states. The master module may be combined with slave modules on a connection bus to control many subsystems. Reprogramming of the master module may occur in the field by use of flash memory, and input/output characteristics may be adjusted during operation of the system, allowing adjustment of systems exhibiting nonlinear response characteristics.
