Appeal No. 2005-0108
Application No. 10/099,828
BACKGROUND
The appellant's invention relates to a communication technique for field devices
in industrial processes. An understanding of the invention can be derived from a
reading of exemplary claims 1 and 22, which are reproduced below.
1. A process device adapted to couple to a fluid process control loop,
the device comprising:
loop interface circuitry adapted to couple to the
process control loop to send and receive loop
signals on the process control loop;
processor circuitry coupled to the loop interface
circuitry and adapted to provide global internet-
compatible data to the loop interface circuitry
for transmission upon the process control loop;
and
a memory coupled to the processor circuitry and
adapted to store data related to global internet
communication.
22. A program on a computer readable medium comprising:
a data access routine for obtaining fluid process data;
a formatting routine for formatting the fluid process
data in accordance with a transmission
protocol;
an addressing routine for adding a destination internet
address to the formatted data; and
