The present application discloses systems and methods for managing assets. In one exemplary embodiment, a system for monitoring an asset is disclosed. The system comprises at least one asset monitoring device, at least one fuel control device, and a central server. The asset monitoring device is configured for use with the asset to collect asset data about the asset. The fuel control device is configured for use with a fuel source to collect fueling data about fueling of the asset. The fuel control device is configured to communicate with the asset monitoring device to receive the asset data from the asset monitoring device. The central server is configured to communicate with the fuel control device to receive the asset data and the fueling data from the fuel control device.

Asset monitoring and fueling system

A valve body has an elongated bore in communication with an inlet port and an outlet port. A valve element is movable within the bore between deactuated and actuated positions. A valve sensor generates a sensor signal indicative of an instantaneous parameter of the valve that changes between the deactuated and actuated positions. A logic unit receives the sensor signal and a pilot command signal that actuates the valve. A predetermined change in the pilot command signal causes the logic unit to determine a cycle parameter responsive to a time period between two predetermined events. At least the beginning or end of the time period corresponds to a predetermined value of the sensor signal. The individual determinations of the cycle parameter are accumulated to obtain an expected cycle parameter. The logic unit generates an indication signal when the cycle parameter exhibits a predetermined variance from the expected cycle parameter.

Control valve system with cycle monitoring, diagnostics and degradation prediction

Various embodiments of a programmable logic controller and a system for programming a programmable logic controller are disclosed. One PLC embodiment comprises an I/O component, a processor, a memory component and a kernel, all contained within a chip.
