DEXPI - Instrumentation Approach



Instrumentation on P&IDs – DEXPI conceptThis document describes the DEXPI (Data EXchange in the Process Industry, ) approach for instrumentation. This approach has major impact on the Proteus schema, which is steered by the Fiatech project IIMM (ISO 15926 Information Models and Proteus Mapping).The Proteus schema release 4.0.1 covers this DEXPI specification.Details: Author: Heiner Temmen, EvonikEdition: 2016-05-03This document uses CamelCase writing for RDL (Resource Definition Library) term.Table of Contents TOC \o "1-3" \h \z \u 1Functional und physical Depiction of Instrumentation in P&IDs PAGEREF _Toc450049929 \h 21.1Functional Design Objects as ISO 15926 Classes PAGEREF _Toc450049930 \h 31.2Asset Specification Objects as ISO 15926 Classes PAGEREF _Toc450049931 \h 42Properties of the Instrumentation Objects PAGEREF _Toc450049932 \h 62.1InstrumentationLoopFunction PAGEREF _Toc450049933 \h 62.2ProcessInstrumentationFunction PAGEREF _Toc450049934 \h 62.3ProcessSignalGeneratingFunction PAGEREF _Toc450049935 \h 62.4ActuatingFunction PAGEREF _Toc450049936 \h 62.5SignalConveyingFunction PAGEREF _Toc450049937 \h 72.6ProcessSignalGeneratingSystem PAGEREF _Toc450049938 \h 72.7PrimaryElement PAGEREF _Toc450049939 \h 72.7.1InlinePrimaryElement PAGEREF _Toc450049940 \h 72.7.2OfflinePrimaryElement PAGEREF _Toc450049941 \h 72.8Transmitter PAGEREF _Toc450049942 \h 82.9ActuatingSystem PAGEREF _Toc450049943 \h 82.10ControlledActuator PAGEREF _Toc450049944 \h 82.11ControlValve PAGEREF _Toc450049945 \h 93Examples PAGEREF _Toc450049946 \h 103.1Instrumentation example based on IEC 62424 PAGEREF _Toc450049947 \h 103.2Instrumentation example based on ISA 5.1 PAGEREF _Toc450049948 \h 133.3Instrumentation example based on DIN 19227 PAGEREF _Toc450049949 \h 16Functional und physical Depiction of Instrumentation in P&IDsThe two major current standards to depict instrumentation objects on a P&ID use different approaches: The ISA 5.1 standard with its concepts and symbols supports the physical approach, i.e. the depiction of the instrumentation devices. The IEC 62424 approach considers the functional objects. A former standard DIN 19227 combined both approaches.Many companies have a mix of these standards as company or as site standards.In general the P&ID is a major document in the engineering and later on in the operating process.The engineering process itself begins with the Front End Engineering (Feed), followed by the Basic Engineering and then with the Detail Engineering. The main tasks are the definitions of the Functional Requirements (Feed), the Functional Design (Basic) and the Asset Specification (Detail). First revisions of the P&IDs are developed during the Basic Engineering with the content of the PFD as requirement documentation, i.e. a P&ID starts with some functional aspects and gets more and more asset specification content in the following phases.Concerning the different standards and different content of a P&ID in its lifecycle, the IIMM concept will support both approaches, the functional and the physical as well.The diagram below shows the Functional Representation in the top half (blue part) and the more Physical Representation below (green part) together in one model.Functional Design Objects as ISO 15926 ClassesRDL DesignationRDL URI / DescriptionInstrumentationLoopFunction SYSTEM that has two or more interlinked PROCESS INSTRUMENTATION FUNCTION's that can operate independently and that has a common Loop Identifier.ProcessInstrumentationFunction that is the union of DETECTING FUNCTION, TRANSDUCING FUNCTION, MEASURING FUNCTION, SIGNAL TRANSMITTING FUNCTION, SIGNAL CONVEYING FUNCTION, PROCESS AMPLIFYING FUNCTION, SIGNAL CONVERTING FUNCTION, PROCESS COMPUTING FUNCTION, BOOLEAN LOGIC EXECUTING FUNCTION, SWITCHING FUNCTION, PROCESS VARIABLE INDICATING FUNCTION, PROCESS VARIABLE RECORDING FUNCTION, PROCESS WARNING FUNCTION, PROCESS PROTECTING FUNCTION, PROCESS VARIABLE CONTROLLING FUNCTION, ACTUATING FUNCTION, and REGULATING FUNCTION.ProcessSignalGeneratingFunction INSTRUMENTATION FUNCTION that is the union of SIGNAL CONVEYING FUNCTION, PROCESS AMPLIFYING FUNCTION, SIGNAL CONVERTING FUNCTION, PROCESS COMPUTING FUNCTION, BOOLEAN LOGIC EXECUTING FUNCTION, SWITCHING FUNCTION, PROCESS VARIABLE INDICATING FUNCTION, PROCESS VARIABLE RECORDING FUNCTION, PROCESS WARNING FUNCTION, PROCESS PROTECTING FUNCTION, PROCESS VARIABLE CONTROLLING FUNCTION.ActuatingFunction that is capable of ACTUATING.SignalConveyingFunction FUNCTION that is the capability of CONVEYING a SIGNAL.ProcessControlFunction requirement for instrumentation and/or control structures relating to Process Engineering.All new classes in the sense of the PCA RDL will be defined in the RDL2 sandbox as soon as possible.The central object is the ProcessInstrumentationFunction, normally represented by a bubble symbol on the P&ID. Some of them can be collected together to an InstrumentationLoopFunction. One reason could be to collect a local and a central requirement together, another could be that requirements with different categories like ‘P’, ‘D’ and ‘F’ will be fulfilled by one multi ProcessSignalGeneratingSystem.A ProcessControlFunction is a special ProcessInstrumentationFunction. In term of IEC 62424 it is a PCE Request with category ‘U’.A ProcessInstrumentationFunction can have ProcessSignalGenerating and ActuatingFunctions as parts in this model as well. Some standards have at this point restrictions, either Process Signal Generating or ActuatingFunctions are allowed. The IIMM concept is more generic. An essential property of the Process Signal Generating and ActuatingFunction is the location, where this function should take place. With this reference, it is possible to connect to the media and stream data or other operation requirements.The SignalConveyingFunction object is used to document the relations between the different objects and to transport information between them.All the functional objectsInstrumentationLoopFunction,ProcessInstrumentationFunction,ProcessControlFunction,ProcessSignalGeneratingFunction andActuatingFunctionare fully tagged objects, i.e. they have unique identifiers in the scope of a plant. This IIMM specification provides all kinds of tagging rules. The only rule is that the identifier has to be unique in the scope of the plant.Asset Specification Objects as ISO 15926 ClassesRDL DesignationRDL URI / RDL DefinitionProcessSignalGeneratingSystem SIGNAL GENERATING ARTEFACT and SYSTEM that consists of more than one PROCESS INSTRUMENTATION ITEM.PrimaryElement INSTRUMENTATION ITEM that has a PRIMARY ELEMENT FUNCTION used for the measurement of a Property or detection of a Status. It is defined independently from any PROCESS INSTRUMENTATION ITEM that is handling that measurement result and that may or may not house that PRIMARY ELEMENT.Transmitter 'detecting instrument' that generates a process variable signal and converts it into an output signal.ActuatingSystem ARTEFACT that includes all auxilliary instances of PROCESS INSTRUMENTATION ITEM that are necessary for it to function.ControlledActuator transducer that is intended to convert energy (electric, mechanical, pneumatic or hydraulic) from an external source into kinetic energy (motion) in response to a signal or or power input.ControlValve valve that can be used to modify (regulate) the fluid flow rate in a process control system. It usually includes an actuator, which responds to a signal from the controlling system and changes the position of the flow controlling element in the valve.Positioner IIMM model of the physical instrumentation objects is very similar to the IEC 61987 approach. ProcessSignalGenerating and ActuatingSystems can have some device components. Of course, only some of the devices are depicted on a P&ID. Typically, flow PrimaryElements and sometimes Transmitter are sensing device objects. A ControlledActuator, a ControlValve and sometimes a Positioner are actuating device objects on a P&ID. The model is open to add other components like a Solenoid Valve.ProcessSignalGeneratingSystems have to fulfill the requirements of the ProcessSignalGeneratingFunctions, ActuatingSystems have to fulfill the requirements of the ActuatingFunction. This is the bridge between the functional and the physical objects in this model.Process Signal Generating and ActuatingSystems are also fully tagged objects, i.e. they have unique identifiers in the scope of a plant. The devices as parts of a ProcessSignalGenerating or ActuatingSystem are sub tags, i.e. they have a sub tag number, which will be unique only in the scope of the tag.
