FIELD: physics, control.
SUBSTANCE: group of inventions relates to maintenance of field devices. Disclosed is a portable device which includes: a communication module configured to communicate via a production process communication channel; a controller connected to the communication module, the controller being configured to access a device description relative to a selected simulated field device; a user interface configured to receive a user input; and wherein the controller is configured to generate communication through the production process communication module to simulate a production process variable based on the user input, wherein the production process variable is transmitted via the production process communication channel to the production process controller as if it was transmitted from the selected simulated field device.
EFFECT: simulating a field device in a portable device.
