Herein described is at least a system for generating one or more control signals based on a voltage provided by an energy storage device. Based on the one or more control signals, the system may selectively enable flow of current through one of: a) a first circuitry when the voltage is equal to or greater than a threshold value, and b) a second circuitry when the voltage is less than the threshold value, wherein the flow of the current through the second circuitry upconverts the voltage associated with the current from a first value to a second value.

The present invention is directed to a method of reprogramming a field device in a process control network using the standard communications protocol for the network, and a reprogrammable field device in the process control network adapted for being reprogrammed using the standard communications protocol for the network. The method and device of the present invention use the standard communications protocol to transmit the downloaded code to the field device and store the downloaded code in the field device while the device is enabled to perform process control. Once the new code is downloaded and stored in the field device, the field device is set to a steady state condition and/or disabled from performing process control, reprogrammed to execute the downloaded code, and reenabled to perform process control.
