A method is disclosed for synchronizing configuration data. The method may include providing a controller network that includes a plurality of control modules and each control module may have registration information stored thereon. The method may include detecting a registration information change associated with a control module and receiving current configuration data from the control module, if the registration information change is detected. The method may also include creating new configuration data for each control module in the controller network based on the received current configuration data, and synchronizing the configuration of each control module with the created new configuration data.

System and method for synchronizing configurations in a controller network

A piston position sensing system in which tabulated resonance width related information is stored in a form correlated with piston travel so that measured resonance width information can be compared with the stored information in determining piston position and compensation for the velocity of the piston is provided by correction for a time difference in serial sensing between the initial and the following extremes of a resonance signal as the piston moves. the compensation is developed from velocity information identified through previous and current processing cycles which assures reliability in detection of the subsequently sensed portion of the resonance signal envelope and enhanced sensitivity and accuracy through automatic application incrementally in a dynamic gain adjustment of the sensing system.

Hydraulic cylinder piston position sensing with compensation for piston

Dynamic gain adjustment in hydraulic piston position sensing that continuously accommodates for changes in signal level is provided by attenuating the gain of the sensing system through a comparison of a measured value with a stored value at each piston position.
