A process device is adapted to couple to a process control loop and communicate on the process control loop. Communication on the process control loop is effected in accordance with an internet protocol. A process communication device is also provided which couples to the process control loop, and an internet. The process communication device provides process control information received from the process control loop, to the internet. Conversely, the process communication device also provides information received from the internet to the process control loop.
