摘要
A field device (14) for use in an industrial process control or monitoring system (10) includes terminals (56H, 56L) configured to connect to a two-wire process control loop (16) configured to carry data and to provide power. In one embodiment, RF circuitry (22) in the field device (14) is configured for radio frequency communication having variable power consumption. In another embodiment, the RF circuitry (22) is coupled to the field device (14) through a separate digital communication bus (100) . A method of modulating the power of RF communication based
