IEC 61512-1:2026 applies to systems, specifications, and their use for implementing batch and related procedure-oriented manufacturing controls in the process industries. This document establishes a reference model framework for procedure-oriented control, defines terms to help explain the model relationships and usage, and describes general criteria for evaluating conformance. This follows the principle of separation between recipe procedural elements and equipment procedural elements enabling operations to define recipes without the need of changes in equipment procedures. This second edition cancels and replaces the first edition published in 1997. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Models and text are modified to provide more detail and clarity. Key clarifications are: 1) Two types of equipment modules are defined: generic and recipe-aware. All recipe-aware equipment modules contain procedural control and can be used as phases in the recipe. 2) Execution of all procedural control contained directly in units is part of the Unit Supervision activity. 3) The relationships between types of recipes, recipe components, and equipment control are more fully described and illustrated. 4) Entity relationship diagrams have been replaced with more intuitive UML instance diagrams, except for the equipment entity model. 5) The transition diagram for the procedural states example has been updated with a more intuitive and complete UML state diagram. 6) References to other standards in the series and to IEC 62264 are included to provide direction for further clarification of selected topics. 7) Activity names are capitalised to help prevent confusion with similar terms, such as their underlying functions. b) Previous Clauses 4 through 6 (now Clauses 4 through 8) were rearranged to provide a clearer top-down organisation of the document. Key changes are: 1) Removing the lower levels of the physical (role-based equipment) model (see 4.4.2) to eliminate redundancy because their groupings are defined by the associated functionality in the equipment entity model and are not meaningful for batch control without those associations. 2) Describing equipment control and the equipment entity model immediately after the physical (role-based equipment) model and describing each level as completely as possible without excessive use of forward references (see 4.4.3). 3) Combining the descriptions of basic, procedural, and coordination control with their usage in each type of equipment entity, providing a single consolidated discussion of each type of control (see Clause 5) 4) Additional considerations to support application of the models have been grouped in Clause 7 to clarify their supporting relationship to the core models. c) Clause 9 was added to define completeness, compliance, and conformance in relation to this document. d) Annex B was added to provide a more expansive procedural state reference model. The model found in Clause 7 can be considered a collapsed version of this more general model. e) Annex C was added to clarify a number of points concerning the models, their application, and the new Clause 9 on conformance and compliance. f) Annex E was added to more fully describe the changes in this update to IEC 61512-1:1997. IEC 61512-1:2026 sapplique aux systemes, aux specifications et a leur utilisation pour la mise en ouvre de commandes de fabrication orientees lots et vers les procedures connexes dans les industries de transformation. Le present document etablit un cadre de modele de reference pour les commandes orientees procedures, definit des termes pour expliquer plus facilement les relations et lutilisation du modele, et decrit des criteres generaux pour levaluation de la conformite de lapplication. Cela suit le principe de separation entre les elements de procedure de recette et les elements de procedure dequipement, ce qui permet aux operations de definir des recettes sans quil soit necessaire de modifier les procedures dequipement. Cette deuxieme edition annule et remplace la premiere edition parue en 1997. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) Les modeles et le texte sont modifies afin de fournir plus de details et de clarte. Les principales clarifications suivantes ont ete effectuees: 1) Deux types de modules dequipement sont definis: modules dequipement generiques et modules dequipement specifiques aux recettes. Tous les modules dequipement specifiques aux recettes comportent une automatisation de procedure et peuvent etre utilises comme des phases dans la recette. 2) Lexecution de toutes les automatisations de procedures contenues directement dans les unites releve de lactivite Supervision dunite. 3) Les relations entre les types de recettes, les composants des recettes et la commande dequipement sont decrites et representees de maniere plus detaillee. 4) Les schemas entite-relation ont ete remplaces par des diagrammes dinstance UML plus intuitifs, a lexception du modele dentites dequipement. 5) Le schema de transition detats pour lexemple detats de procedure a ete mis a jour avec un schema detats UML plus intuitif et complet. 6) Des references a dautres normes de la serie et a lIEC 62264 sont incluses afin de fournir des indications permettant de clarifier certains sujets. 7) La premiere lettre des noms dactivites est ecrite en majuscule pour eviter toute confusion avec des termes similaires, comme leurs fonctions sous-jacentes. b) Les Articles 4 a 6 de la version precedente (desormais numerotes Articles 4 a 8) ont ete reorganises afin de fournir une organisation descendante plus claire du document. Les principales modifications suivantes ont ete apportees: 1) Suppression des niveaux inferieurs du modele physique (equipements fon
