ISA95 Common Object Model

an extension package for node-opcua

This NPM module implements the ISA95 extensions for node-opcua, to ease the creation of ISA95 OPCUA server, in the industrial world.

It follows the specification in OPCUA ISA95 Specification

installation

  • install node-opcua-isa95 module along side node-opcua
npm install node-opcua  --save
npm install node-opcua-isa95 --save
  • use require("node-opcua-isa95")(opcua); to enrich node-opcua with the ISA95 add-on
var opcua = require("node-opcua");
 
// add server ISA95 extension to node-opcua
require("node-opcua-isa95")(opcua);
 
 
var xmlFiles = [
    opcua.standard_nodeset_file,
    opcua.ISA95.nodeset_file
];
 
var server = new opcua.OPCUAServer({
    nodeset_filename: xmlFiles,
// details left out for clarity
});
 
 
function post_initialize() {
    console.log("initialized");
    var addressSpace = server.engine.addressSpace;
 
    // add your ISA95 node in the addressSpace here
    server.start(function() {
        console.log("Server is now listening ... ( press CTRL+C to stop)");
        console.log("port ", server.endpoints[0].port);
        var endpointUrl = server.endpoints[0].endpointDescriptions()[0].endpointUrl;
        console.log(" the primary server endpoint url is ", endpointUrl );
    });
}
 
server.initialize(post_initialize);

API documentation

Equipment

ISA 95 logical Equipments can be added to the addressSpace and defined using the following API.

opcua.AddressSpace#addEquipmentClassType(options)

add a new EquipmentClassType to the addressSpace

options type description
options.browseName {String/QualifiedName} the browseName of the new node equipment
[options.equipmentLevel] {EquipmentLevel} the EquipmentLevel

example

var weldingRobotClassType = addressSpace.addEquipmentClassType({
    browseName: "WeldingRobotClassType",
    equipmentLevel: opcua.ISA95.EquipmentLevel.EquipmentModule
});
 

opcua.AddressSpace#addEquipmentType(options)

add a new EquipmentType to the addressSpace

options type description
options.browseName {String/QualifiedName} the browseName of the new node equipment

opcua.ISA95.EquipmentLevel

(see Table 36 – ISA95EquipmentElementLevelEnum Values )

This DataType is an enumeration that defines the equipment element levels defined in ISA-95. Its values are defined in a below table.

Value Description
Enterprise An enterprise is a collection of sites and areas and represents the top level of a role based equipment hierarchy.
Site A site is a physical, geographical, or logical grouping determined by the enterprise. It may contain areas, production lines, process cells, and production units.
Area An area is a physical, geographical, or logical grouping determined by the site. It may contain work centres such as process cells, production units, production lines, and storage zones.
ProcessCell Process cells are the low level of equipment typically scheduled by the Level 4 and Level 3 functions for batch manufacturing processes.
Unit Units are low level of equipment typically scheduled by the Level 4 and Level 3 functions for batch manufacturing processes and continuous manufacturing processes.
ProductionLine Production lines are low levels of equipment typically scheduled by the Level 4 or Level 3 functions for discrete manufacturing processes.
WorkCell Work cells are low levels of equipment typically scheduled by the Level 4 or Level 3 functions for discrete manufacturing processes.
ProductionUnit Production units are the lowest level of equipment typically scheduled by the Level 4 or Level functions for continuous manufacturing processes.
StorageZone Storage zones are low level of material movement equipment typically scheduled by the Level 4 and Level 3 functions for discrete, batch and continuous manufacturing processes.
StorageUnit Storage units are low level of material movement equipment typically scheduled by the Level 4 and Level 3 functions for discrete, batch and continuous manufacturing processes.
WorkCenter Work centres are typically the grouping of equipment scheduled by the Level 4 or Level 3 functions.
WorkUnit A work unit is any element of the equipment hierarchy under a work centre. Work units are the lowest form of elements in an equipment hierarchy that are typically scheduled by Level 3 functions.
EquipmentModule An equipment module entity is an engineered subdivision of a process cell, a unit, or another equipment module.
ControlModule A control module entity is an engineered subdivision of a process cell, a unit, an equipment module, or another control module.
