A distributed hydraulic system having a plurality of hydraulic functions each including a hydraulic actuator, a valve assembly that controls flow of fluid to the hydraulic actuator, and a function controller which operates the valve assembly. The function controllers exchange messages over a communication network which has a finite bandwidth. Access to the network is controlled by determining which function controllers govern high priority operations and allowing those function controllers to send messages as often as once every first interval of time. The other function controllers are limited to sending messages no more often than once every second interval of time, which is longer than the first interval of time. |
