This recommended practice (RP) addresses the processes required to successfully implement process control systems for oil and gas production, refinery, and petrochemical services. The major topics addressed are:

• Part 1. The basic functions that a PCS may need to perform, and recommended methodologies for determining the functional and integration requirements for a particular application.
• Part 2. The practices to select and design the installation for hardware and software required to meet the functional and integration requirements.
• Part 3. The project organization, skills, and management required to first execute a process control project and then to own and operate a PCS.

This document is not intended to present a tutorial on the subjects discussed, but rather to aid the reader in identifying and understanding the basic concepts of PCSs.
