Abstract
A wireless field device for use in an industrial process includes input/output terminals configured to couple to a process interface element. A discrete input/output channel is configured to receive a discrete input from the process interface element through the input/output terminals when configured as a discrete input channel. The discrete input/output channel is further configured to provide a discrete output to the process interface element through the input/output terminals when the discrete input/output channel is configured as discrete output channel. Wireless communication circuitry is configured to transmit and receive information. A controller communicates information through the wireless communication circuitry and operates in accordance with configuration information to configure the input/output channel as an input channel when the input/output terminals are connected to a discrete process variable sensor, and further configure the discrete input/output channel as a discrete output channel when the input/output terminals are coupled to a discrete control element.
