    摘要： Methods, apparatus, systems and articles of manufacture are disclosed to audit process control alarms. An example disclosed method includes identifying components in the process control system that correspond to alarms to be audited. The example method also includes if a query to request a status of a particular one of the alarms to be audited is not in a status update queue, generating a query associated with the audit report request to request the status of the particular one of the alarms from the corresponding component. Otherwise, if the query to request the status of a particular one of the alarms to be audited is in the status update queue, associating the audit report request to the query. The example method also includes transmitting, via a process control system bus, the queries to be designated as low priority.

    摘要： Example apparatus and methods to remove power from a field device are disclosed. An example apparatus includes a first switch to control power to the field device, and a second switch comprising a first gate and a second gate. The second gate is electrically coupled in parallel to the first gate, and the second switch is electrically coupled in series to the first switch. The example apparatus also includes a first diagnostics controller to control the first and second gates, a first processor to control the first switch, a third switch to control power to the field device, and a fourth switch comprising a third gate and a fourth gate. The fourth gate is electrically coupled in parallel to the third gate, and the fourth switch is electrically coupled in series to the third switch. The example apparatus also includes a second processor to control the third switch, and a second diagnostics controller to control the third and fourth gates.

    摘要： Systems and methods to monitor pump cavitation are disclosed. An example method includes monitoring a pressure parameter and a vibration parameter associated with an asset in an operating process unit. The example method includes calculating a manipulated pressure value based on the pressure parameter. The example method includes calculating a manipulated vibration value based on the vibration parameter. The example method includes determining a state of cavitation associated with the asset based on at least one of the manipulated pressure value or the manipulated vibration value.

    摘要： Methods and apparatus to configure process control systems based on generic process system libraries are disclosed. An example method includes instantiating an instance of a generic process system library. The instance is associated with items of equipment and corresponding process signals of a process control system. The generic process system library comprises at least one of generic process graphic data or generic control strategy data corresponding to the items of equipment and the corresponding process signals of the process control system. The example method further includes configuring the instance of the generic process system library by incorporating process-specific data associated with the operation of the process control system with the at least one of the generic process graphic data or the generic control strategy data.
