Abstract: There is described a controller and method for managing a flow unit. A measured full flow corresponding to a full open position of a flow control element of the flow unit is detected. A calibration nominal is established based on the measured full flow, and calibration relative flows are calculated based on the calibration nominal and calibration measured flows corresponding to calibration positions of the flow control element. Subsequent to calibration, an operation measured flow of the flow unit and an operation position of the flow control element are detected. A dynamic nominal is determined based on the operation measured flow and a particular calibration relative flow corresponding to the operation position of the flow control element. The operation position of the flow control element is controlled based on the operation measured flow and the dynamic nominal.

Abstract: A sourceless co-packaged optical-electrical chip can include a plurality of different optical transceivers, each of which can transmit to an external destination or internal components. Each of the transceivers can be configured for a different modulation format, such as different pulse amplitude, phase shift key, and quadrature amplitude modulation formats. Different light sources provide light for processing by the transceivers, where the light source and transceivers can be configured for different applications (e.g., different distances) and data rates. An optical coupler can combine the light for the different transceivers for input into the sourceless co-packaged optical-electrical chip via a polarization maintaining media (e.g., polarization maintaining few mode fiber and polarization maintaining single mode fiber), where another coupler operates in splitting mode to separate the different channels of light for the different transceivers according to different co-packaged configurations.

A calibration nominal is established based on the measured full flow, and calibration relative flows are calculated based on the calibration nominal and calibration measured flows corresponding to calibration positions of the flow control element. Subsequent to calibration, an operation measured flow of the flow unit and an operation position of the flow control element are detected. A dynamic nominal is determined based on the operation measured flow and a particular calibration relative flow corresponding to the operation position of the flow control element. An operation relative flow and a relative flow setpoint are determined based, in part, on the dynamic nominal. The operation position of the flow control element is controlled based the operation relative flow and relative flow setpoint.

Abstract: There is described a system and method for managing control performance of a field device receiving variable data. Variable and setpoint references corresponding to a control loop of the field device are identified. A time delay normal period based on expected oscillations of the variable reference and first settling thresholds associated with the setpoint reference are also identified. An offnormal timestamp is generated based on the variable reference relative to one or more second settling thresholds associated with the setpoint reference. A normal timestamp is generated based on the variable reference relative to the first settling thresholds. A settling time of the control performance is determined based on the normal timestamp, the offnormal timestamp, and the time delay normal period. One or more performance features of the field device are modified based on the determined settling time.

Abstract: There is described a system and method for managing control performance of a field device receiving variable data. Variable and setpoint references corresponding to a control loop of the field device are identified. A time delay normal period based on expected oscillations of the variable reference and settling limits associated with the setpoint reference are also identified. An offnormal timestamp is generated based on the variable reference relative to one or more second pre-settling limits associated with the setpoint reference. A normal timestamp is generated based on the variable reference relative to the settling limits. A settling time of the control performance is determined based on the normal timestamp, the offnormal timestamp, and the time delay normal period. One or more performance features of the field device are modified based on the determined settling time.
