摘要： A system and method for controlling a remote valve includes temporarily driving or activating a battery-powered pilot valve assembly to place an operatively coupled output valve in a switch position. One or more processors receives a temperature measurement associated with an operating environment of the battery-powered pilot valve assembly, compares the received temperature measurement to a temperature threshold level, and continuously drives the battery-powered pilot valve assembly to maintain the output valve in the switch position if the temperature measurement is below the temperature threshold level.

摘要： An accelerometer wireless position transducer or sensor is physically coupled to a control device in a process control system and includes an accelerometer that generates a signal based on a position of the control device or its actuator. The transducer converts the accelerometer signal into a wireless signal that includes a value indicative of the actuator position, and causes the wireless position feedback signal to be transmitted over a wireless channel to a valve controller, e.g., by using a short-range wireless protocol. The controller controls the valve based on the value included in the wireless signal. In some configurations, the feedback signal is received at a device paired with the transducer, and the paired device transmits the feedback signal to the controller. The paired device may be paired with multiple transducers and/or sensors, and may transmit various feedback signals to multiple recipient controllers and other devices.

摘要： Techniques for delaying the publication of data to a network by a device in a process control system or plant include obtaining, at the device, data to be published to the network; storing the obtained data and a corresponding timestamp in a cache; triggering a publication of cached data; and, based on the trigger, publishing the oldest cached data to the network during the publishing timeslot assigned to the device. The cached data may correspond to a sample rate of the device and may include multiple instances of data obtained over time. The device includes a network interface, a cache, and a publisher, and the device may be configured to operate in the delayed publishing mode, or to operate in an immediate publishing mode in which currently obtained data that has not been cached is published to the network during the publishing time slot assigned to the device.
