This report is intended to discuss the project undertaken to design, analyse and fabricate a simple control loop using a fieldbus foundation protocol. The first control systems used mechanical and pneumatic controllers and were designed merely to achieve stability rather than economic performance. Later in the 1970s, distributed control system (DCS) emerged to replace the conventional technology. In DCS, a central processor controls all parameters however, it has limitation in term of reliability, robustness and cost. This lead to the introduction of network communication for industrial process known as the fieldbus system replacing the DCS architecture by enabling distribution of control function to equipment in the field such as sensors, controllers and actuators. In this project configuration and implementation procedure for the development of fieldbus process loop is presented involving three process variables that are the temperature, pressure and level together with PID and feedforward control strategies. The methodology towards accomplishing the project includes the theoretical and technical research, the installation and commissioning, the configuration network of fieldbus protocol together with HART protocol, the troubleshooting, operation and maintenance, and the analysis of the fieldbus advantages and benefits. The findings demonstrates the benefits of the fieldbus system in term of cost saving, data quality and quantity, simpler and better controllability.
