A class with identifier http://rds.posccaesar.org/ontology/plm/rdl/PCA_100006479

MetadataThis section provides information about 'PCA_100006479' itself.

Source ontology norsok-z001
Comment Main components of a sequence are:n - Steps with associated actions;n - Transitions with associated logic conditions;n - Directed links between steps and transitions.nnThe sequential function chart may be presented on separate pages to avoid cluttering the main SCD. nnThe SCD’s shall be made per process system and supported by a functional specification.
NORSOK Z-001 rationale System Control Diagram shall be used to specify and document process control and process shutdown application within the control systems.nnThe method consists in principle of two parts.nn(1) Use of a defined set of function blocks, andn(2) a diagram representation of usage of these function blocks and its interconnections.nnThe diagram has a presentation of the process as background. The content of multiple P&ID’s is simplified and combined into the SCD’s as the control and shutdown logic is laid out there.nnSystem Control Diagrams shall be in accordance with the standard referred to in IEC 63131.nnThe SCD standard also covers sequential control.
