|Publication Date:||1 September 1995|
1.2.1 SECTION 2--SCOPE
Section 2 of RP 554 provides considerations for the selection, specification, and installation of automatic control systems for use in refinery processes. Single-loop controllers, multiloop controllers, programmable controllers, and distributed control systems are discussed with relevant design and application engineering information.
1.2.2 SECTION 3--SCOPE
Section 3 recommends systems, installation considerations, and testing procedures for alarms and protective devices used in refineries.
1.2.3 SECTION 4--SCOPE
Section 4 of this document covers the performance requirements, networks, hardware, software, and infrastructure associated with the process control computing environment. The intent of this recommended practice is to provide guidance to those parties developing detailed specifications for computing resources used for process control and associated functions in the petroleum industry. This document is based on the philosophy of using widely accepted computing industry standards and avoiding custom or proprietary approaches.
This document does not cover the application software requirements associated with process control, advanced control, process optimization, and data acquisition.
1.2.4 SECTION 5--SCOPE
Section 5 presents recommended practices for the design and installation of control centers for processing operations. Recommended practices for blast-resistant control centers design is not within the scope of this document.
