Design and Implementation of Field Bus Device Management System Based on HART Protocol

The highway addressable remote transducer (HART) was introduced in detail, on the basis, a field bus device management system based on HART protocol was designed. This system adopt C/S mode, and has the function of reading, writing as well as diagnosis, adjustment and management of devices parameters. Meanwhile, this article focus on solving the situation when there is no EDDL file, which is realizing the management of HART universal devices and HART dedicated devices based on the classification of commands in the HART protocol in order to complete the test and make the system to be steady state finally.
