According to some embodiments, system and methods are provided, comprising at least one asset; a computer programmed with a data share module for the asset, the data share module for controlling data flow in the asset; the computer including a data share processor and a memory in communication with the data share processor, the memory storing the data share module and additional program instructions, wherein the data share processor is operative with the data share module and additional program instructions to perform functions as follows: receiving a message from a source at the data share module; determining, via the data share module, whether the source is one of a non-real time domain of the asset and the real-time domain of the asset; determining, via the data share module, when a destination is able to respond to the message, wherein the destination is one of the non-real time domain and the real-time domain, and wherein the destination is different from the source; transmitting, via the data share module, the message directly to the destination when the destination is able to respond to the message; receiving a response to the message; and generating an operating response of the asset based on the response. Numerous other aspects are provided.

Unified real-time and non-real-time data plane

A hydraulic system for an operator controlled machine, the system including at least one actuator for moving a machine component, a source of pressurized fluid for delivering pressurized fluid at a system pressure to a control valve which is operable under operator control, to control the flow of fluid from the source to the actuator at a load pressure, along a load pressure path, a flow control apparatus for controlling the flow of fluid from the source to the control valve, the flow control apparatus including an actuating part which is biased by a resilient device to a condition in which the flow control apparatus provides for a maximum flow of fluid to the control valve, actuating part movement by the resilient device being resisted by system pressure fluid and being supported by fluid at a control pressure, the control pressure being derived from the load pressure, and wherein the system includes a pressure control device to which the load pressure is communicated, the pressure control device being operated under operator control either to deliver the control pressure to the flow control device at load pressure or a modified pressure which is less than the load pressure.
