Abstract
Techniques for accessing and controlling field devices to collect data and convert protocols include receiving data encoded in a process control protocol, extracting a payload, storing some of the payload, and transmitting some of the payload in a general-purpose computing communication protocol via a wireless network. A method of accessing a field device includes receiving a command of a user from a user communicator, identifying a target field device, generating a command, encoding a protocol-encoded data set, and transmitting the protocol-encoded data set to the target field device. A field communicator device includes instructions for retrieving and interpreting field device data, storing the data, and transmitting the data. A computing system includes a field communicator, wireless user communicator, and a wireless computer network for accessing and controlling field devices in a process plant.
