    Abstract: A process device (34, 360, 500, 600) includes a controller (36, 362) and a wireless communications module (32, 366, 506). The wireless communications module (36, 366, 506) is coupled to the controller (36, 362). A power generation module (38, 365, 508, 602, 604, 620) is provided to generate electricity for the process device (32, 366, 506). The power generator module (38, 365, 508, 602, 604, 620) can be disposed within the process device (32, 366, 506) or it can be a separate unit coupled to the process device (32, 366, 506).

    Abstract: A process variable transmitter (200) connects a serial bus (232) to an accessory load. A supply limiter circuit (234) provides a first supply current limit and provides a stored energy output (236). A recessive driver circuit (238) draws a drive current from the stored energy output (236) and couples the drive current to the serial bus (232). The recessive driver circuit (238) provides a drive current limit. A dominant driver circuit (242) has a dominant state in which it conducts the drive current, and an inactive state in which the drive current is available to the accessory load.
