    Abstract: A method for replacing a controller on a process device that avoids downtime on a process line. The method may include retrieving data from a first controller on a valve assembly, the data comprising information that defines values for operating parameters on the first controller, removing the first controller from the valve assembly, coupling a second controller to the valve assembly, and storing data on the second controller, the data comprising information that defines the values for operating parameters corresponding with the first controller.

    Abstract: A controller for a valve assembly that is configured to meet requirements for use in hazardous areas. These configurations may regulate flow of instrument air to a pneumatic actuator to operate a valve. The controller may comprise enclosures, including a first enclosure and a second enclosure, each having a peripheral wall forming an interior space, and circuitry comprising a barrier circuit disposed in the interior space of one of the enclosures that power limits digital signals that exits that enclosure. In one example, the peripheral wall of enclosures are configured to allow instrument air into the interior space of the first enclosure but to prevent instrument air from the interior space of the second enclosure.

    Abstract: A valve positioner for use on a process control valve or “valve assembly.” The process control valve may include a pneumatic actuator and a valve having a closure member coupled with the pneumatic actuator and moveable relative to a seat. The valve positioner may couple to the pneumatic actuator to provide a pneumatic signal to set a position of the closure member relative to the seat. An accelerometer may couple with the valve positioner. The accelerometer may generate data in response to orientation of the valve positioner. In one implementation, the configurations can use this data to ensure proper visualization of data on a display. The data also permits the device to properly manage operating modes, like tight shut-off or fully-opened mode, that may prevail due to orientation issues that cause defects in a measured position for a closure member that regulates flow of material through the valve assembly.

    Abstract: A valve assembly that is configured to wirelessly transmit data using near-field communication protocols. The embodiments may include a passive, NFC-enabled device disposed inside of a controller (or “valve positioner”). This NFC-enabled device can operate as a communication “port” to allow data exchange with a handheld computing device, like a smartphone or tablet. This feature can afford end users (e.g., technicians) ready access to data on the valve assembly via the handheld computing device.
