Fieldbus is an all-digital, high-speed, two-way field communication protocol for process control. It will replace the 4 to 20 mA control signal that is the world-wide standard today. When accepted and available to all distributed control system (DCS), programmable logic controller (PLC), remote terminal unit (RTU), control valve, measurement and analytical instrumentation suppliers, fieldbus will provide tremendous construction, operational, maintenance, safety and environmental benefits to the HPI. The key driver for fieldbus is change-changing business conditions and demands in the HPI combined with changing technology to help meet those demands. Increased competition and rising demands from customers and regulatory agencies, combined with the need to understand and document more information, are mandating more from process automation equipment. At the same time, technology advancements such as micro-processor-based instrumentation using application-specific integrated circuits (ASIC) and solid-state sensors, have increased performance and quantity of information available from today's instrumentation. But the fact that an open digital communication standard does not exist has limited accessibility of this information. The paper discusses protocols and the benefits of a standard.
