Embodiments of the present invention generally provide a field-mountable
process device that receives digital information from one or more process
devices, and provides an associated analog output. Embodiments of the
present invention include providing a wireless interface to the
field-mounted process device such that configuration and/or diagnostic
information can be communicated between the field-mounted process device
and one or more additional devices. In some embodiments, the
field-mounted process device can be completely powered by the digital
process communication loop to which it is coupled. Finally, embodiments
of the present invention also include generating and storing within the
field-mounted process device a mapping between one or more field devices
communicating in accordance with a digital process communication protocol
and an analog output of the field-mounted process device.
