Standards Development

Scope

This document addresses automated procedures that primarily reside on systems within the supervisory control, monitoring, and automated process control section (as defined by ISA-95 functional levels 1 and 2) of a production process (as defined by ISA‑95 functional level 0). This standard does not address procedure execution at the operations management functional level (as defined by defined by ANSI/ISA-95 level 3). The interaction with manual procedures is within the scope, but manual procedures are outside the scope of this standard. Manual procedures include manual operations by the operator using the control systems.

This standard applies to continuous processes. The automation of procedures for batch process operations is outside the scope of this standard.

This standard applies to automated procedures that reside in any such control system in levels 0, 1, and 2 of ANSI/ISA-95.00.01-2010, including the basic process control system (BPCS) but excluding any systems performing safety instrumented functions (SIF) with a claimed safety integrity level (SIL) ≥ 1.

This standard also applies to the interfaces of such procedures with a safety instrumented system (SIS). However, automated procedures that are implemented within a safety instrumented system are outside of the scope of this standard
