System for physical location of field devices in process plants

A system for determining the physical location of field devices in a process plant, in which each field device can be identified uniquely and is connected to a control system through a communication network, wherein said plant has a locally oriented hierarchical structure and a plant identification system based on said locally oriented hierarchical structure, said system comprising:

• a fixed-position device associated with each field device, said fixed-position device comprising:
• at least one processing unit, one communication device with an antenna for wire-free communication, and a non-volatile memory, said memory storing details relating to the position of the installation location of said field device such that said details can be called up, and a mobile device comprising:
• at least one processing unit, a keyboard, a display unit and a communication device which corresponds to said communication device in said fixed-position device and has an antenna for wire-free communication, said display unit for visualizing the details which have been called up relating to the position of the installation location of the field device in the process plant.
