OPC UA Pub\/Sub (UADP\/MQTT) enables real-time multicast for factory floor. OPC UA FX (Field eXchange) extends to controller-to-controller communication 2025-2027.\n<\/div>\n<p>For <strong>manufacturing IIoT architects and automation engineers in 2027<\/strong>, OPC UA (IEC 62541) has become the de facto industrial interoperability standard. However, the real power of OPC UA lies not in the base protocol but in the <strong>Companion Specifications<\/strong> \u2014 standardized information models that define how specific manufacturing domains expose their data semantically. This guide details the major Companion Specifications (PackML, ISA-95, Euromap, Sercos, MTConnect alignment), the OPC UA Pub\/Sub transport evolution (UADP multicast, MQTT broker), the emerging OPC UA FX (Field eXchange) for controller-to-controller, vendor support matrices, and integration patterns with OEE platforms. Understanding these specifications is critical for: selecting automation equipment that supports the right Companion Specs, designing plant-wide IIoT architectures with semantic interoperability, and ensuring OEE\/MES platforms can consume machine data without custom per-machine integration.<\/p>\n<h2>OPC UA Companion Specifications: the semantic layer for manufacturing<\/h2>\n<p>Base OPC UA provides a generic data modeling framework (nodes, references, attributes, methods, events). Companion Specifications <strong>define domain-specific information models<\/strong> on top of this base, specifying:<\/p>\n<ul>\n<li>Which ObjectTypes and VariableTypes represent domain concepts (e.g., a packaging machine, an injection mold, a CNC spindle)<\/li>\n<li>Which properties and variables each type exposes (e.g., OEE components, cycle count, machine state, alarm conditions)<\/li>\n<li>Which methods are callable (e.g., start\/stop\/pause, recipe download, parameter change)<\/li>\n<li>Which events are generated (e.g., state transitions, alarm activations, production counter increments)<\/li>\n<\/ul>\n<p>Without Companion Specifications, each machine vendor exposes OPC UA data differently \u2014 different variable names, different structures, different semantics. With Companion Specifications, all vendors in a domain use the same information model, enabling <strong>plug-and-play interoperability<\/strong>.<\/p>\n<h2>Major Companion Specifications for manufacturing<\/h2>\n<h3>PackML (OMAC \/ ISA-TR88) \u2014 packaging and discrete manufacturing<\/h3>\n<table>\n<thead>\n<tr>\n<th>Aspect<\/th>\n<th>Detail<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Specification<\/td>\n<td>OPC 30050 \u2014 PackML (Packaging Machine Language)<\/td>\n<\/tr>\n<tr>\n<td>Origin<\/td>\n<td>OMAC (Organization for Machine Automation and Control) + ISA-TR88.00.02 state model<\/td>\n<\/tr>\n<tr>\n<td>Scope<\/td>\n<td>Packaging machines, filling lines, labeling, palletizing \u2014 extends to general discrete manufacturing<\/td>\n<\/tr>\n<tr>\n<td>Key concepts<\/td>\n<td>17 machine states (Execute, Idle, Stopped, Held, Suspended, Aborting, Clearing, etc.), PackTags (Admin, Status, Command), unit modes (Production, Maintenance, Manual), counters (produced, defective, consumed)<\/td>\n<\/tr>\n<tr>\n<td>OEE relevance<\/td>\n<td>PackML state model directly maps to OEE Availability calculation: Execute = productive time, all other states = various types of downtime (planned\/unplanned).

Without them, each machine vendor uses different variable names and structures. With them, all vendors in a domain use the same model \u2014 enabling plug-and-play interoperability. Major specs: PackML (packaging), ISA-95\/B2MML (ERP-MES), Euromap 77\/82\/83 (plastics), CNC (OPC 40501), Sercos (motion).<\/p>\n<h3>How does PackML relate to OEE?<\/h3>\n<p>PackML ISA-TR88 state model directly maps to OEE Availability: Execute state = productive time, all others = downtime types. PackTags include standard counters (ProdConsumedCount, ProdDefectiveCount, ProdProcessedCount) for OEE Performance and Quality components. OEE platforms consuming PackML data get standardized A \u00d7 P \u00d7 Q inputs without custom per-machine mapping. Dominant in F&#038;B packaging (Krones, Sidel, Tetra Pak, KHS, GEA).<\/p>\n<h3>MTConnect or OPC UA for CNC?<\/h3>\n<p>Both. MTConnect stronger in North America (Mazak, Haas, Hurco, Makino), OPC UA stronger in Europe (Siemens SINUMERIK, Heidenhain, DMG MORI EU). Modern CNC controllers support both. OPC UA Companion Spec for CNC (OPC 40501) + MTConnect-OPC UA companion enable bidirectional mapping. Convergence underway. OEE platforms should consume either protocol.<\/p>\n<h3>What is OPC UA Pub\/Sub and why does it matter?<\/h3>\n<p>OPC UA Pub\/Sub (Part 14) adds publish-subscribe transport to OPC UA: UADP over UDP multicast (real-time, TSN-capable, sub-millisecond), MQTT transport (cloud integration, edge-to-cloud), AMQP (enterprise messaging). Solves scaling limitations of Client\/Server for large IIoT deployments (thousands of data points, hundreds of subscribers). Enables OPC UA data distribution via standard MQTT brokers (HiveMQ, EMQX).<\/p>\n<h3>What is OPC UA FX?<\/h3>\n<p>OPC UA FX (Field eXchange) extends OPC UA to controller-to-controller communication (traditionally PROFINET, EtherNet\/IP, EtherCAT domain). Integrates IEEE 802.1 TSN for deterministic Ethernet. Includes OPC UA Safety (IEC 62541-100, SIL 3 \/ PL e). First products 2025-2027 (Siemens, Beckhoff, B&#038;R, Bosch Rexroth). Long-term vision: one protocol sensor-to-cloud.<\/p>\n<h3>How do Euromap specs work for plastics?<\/h3>\n<p>Euromap OPC UA Companion Specifications standardize data from plastics machinery: Euromap 77 (injection molding \u2014 cycle time, mold data, shot counter, energy), Euromap 82 (extrusion), Euromap 83 (blow molding), Euromap 84 (hot runners), Euromap 79 (robots). Mandatory for new machines from major European OEMs (Engel, KraussMaffei, Arburg, Sumitomo Demag). OEE platforms read standardized data without custom integration.<\/p>\n<h3>Which automation vendors have best OPC UA Companion Spec support?<\/h3>\n<p>Best support 2027: Siemens (PackML, Euromap, CNC SINUMERIK, Pub\/Sub, FX roadmap), B&#038;R ABB (PackML mapp, Euromap 77\/82\/83, Pub\/Sub, FX), Beckhoff (PackML, Euromap 77, CNC, Pub\/Sub, FX), Bosch Rexroth ctrlX (PackML, Euromap 77, CNC, Pub\/Sub, FX). Rockwell: strong PackML AOI but limited Pub\/Sub and no FX. Fanuc\/Mitsubishi: CNC strong but limited packaging specs.<\/p>\n<h3>How does this integrate with OEE platforms?<\/h3>\n<p>OEE platform as OPC UA Client reads standardized Companion Spec data from machine OPC UA Servers. PackML provides state model + counters mapping directly to OEE A \u00d7 P \u00d7 Q. Euromap provides cycle data + quality counters. CNC spec provides spindle utilization + part count. TeepTrak Pulse supports OPC UA Client + fallback TeepTrak Box edge sensor for non-OPC UA machines. Dual-path covers heterogeneous 40+ site landscape (Hutchinson pattern).<\/p>\n<h3>What about legacy machines without OPC UA?<\/h3>\n<p>Legacy machines (no OPC UA server, old PLC, manual machines) need alternative: (1) retrofit OPC UA server (Kepware, Prosys, Matrikon, Softing, Unified Automation), (2) edge sensor independent of PLC (TeepTrak Box \u2014 clamp-on, 1 hour install, no PLC modification), (3) IoT gateway with protocol conversion (Siemens IOT2050, Advantech WISE, Moxa). TeepTrak&#8217;s dual-path (OPC UA for capable + edge sensor for legacy) covers mixed landscape.<\/p>\n<h3>What&#8217;s the roadmap for OPC UA in manufacturing?<\/h3>\n<p>OPC UA manufacturing roadmap 2025-2030: (1) Companion Specifications adoption continues (20+ domain specs published, 50+ in development), (2) OPC UA Pub\/Sub MQTT becomes standard for cloud integration, (3) OPC UA FX replaces proprietary fieldbus for controller-to-controller (PROFINET, EtherNet\/IP coexist but decline), (4) OPC UA + TSN deterministic Ethernet converges IT\/OT networks, (5) cloud-native OPC UA (discovery, security, multi-tenancy). Industrial consensus: OPC UA is the long-term winner for manufacturing interoperability.<\/p>\n<h2>Conclusion<\/h2>\n<p>OPC UA Companion Specifications are the <strong>semantic layer for manufacturing IIoT interoperability<\/strong> in 2027. Key specifications: <strong>PackML<\/strong> (packaging\/discrete, ISA-TR88 state model \u2192 OEE Availability mapping), <strong>ISA-95\/B2MML<\/strong> (ERP-MES integration), <strong>Euromap 77\/82\/83<\/strong> (plastics injection\/extrusion\/blow molding), <strong>OPC 40501 CNC<\/strong> (machining centers), and many more domain-specific specs. <strong>OPC UA Pub\/Sub<\/strong> (UADP multicast + MQTT transport) solves scaling for large IIoT deployments. <strong>OPC UA FX<\/strong> extends to controller-to-controller with TSN for the &#8220;one protocol sensor-to-cloud&#8221; vision. Best vendor support: Siemens, B&#038;R\/ABB, Beckhoff, Bosch Rexroth. For OEE platforms: Companion Specs enable standardized machine data consumption without custom per-machine mapping \u2014 PackML machines expose standardized state + counter PackTags, Euromap machines expose standardized cycle + quality data. TeepTrak Pulse supports OPC UA Client + edge sensor fallback for full heterogeneous landscape coverage.<\/p>\n<p><strong>Next step<\/strong>: download the TeepTrak OPC UA integration guide or request a free OPC UA architecture assessment for your manufacturing IIoT landscape.<\/p>\n<div class=\"teeptrak-cta-final\">    <div class=\"teeptrak-form-container \">\n        <h3 class=\"teeptrak-form-title\">Request a demo<\/h3>                \n        <form id=\"teeptrak-6a28ea55b027e\" class=\"teeptrak-form\" data-form-type=\"demo_request\">\n            <div style=\"position:absolute;left:-9999px;\"><input type=\"text\" name=\"website_url\" value=\"\" tabindex=\"-1\"><input type=\"text\" name=\"fax_number\" value=\"\" tabindex=\"-1\"><\/div>            \n            <div class=\"teeptrak-form-row teeptrak-form-row-half\">                <div class=\"teeptrak-form-field\">\n                    <label>First name <span class=\"required\">*<\/span><\/label>                    \n                                            <input type=\"text\" name=\"first_name\" required placeholder=\"\">\n                                    <\/div>\n                            <div class=\"teeptrak-form-field\">\n                    <label>Name <span class=\"required\">*<\/span><\/label>                    \n                                            <input type=\"text\" name=\"last_name\" required placeholder=\"\">\n                                    <\/div>\n                            <div class=\"teeptrak-form-field\">\n                    <label>E-mail <span class=\"required\">*<\/span><\/label>                    \n                                            <input type=\"email\" name=\"email\" required placeholder=\"\">\n                                    <\/div>\n                            <div class=\"teeptrak-form-field\">\n                    <label>Phone <span class=\"required\">*<\/span><\/label>                    \n                                            <input type=\"tel\" name=\"phone\" required placeholder=\"\">\n                                    <\/div>\n                            <div class=\"teeptrak-form-field\">\n                    <label>Business <span class=\"required\">*<\/span><\/label>                    \n                                            <input type=\"text\" name=\"company\" required placeholder=\"\">\n                                    <\/div>\n                            <div class=\"teeptrak-form-field\">\n                    <label>Job<\/label>                    \n                                            <input type=\"text\" name=\"job_title\"  placeholder=\"\">\n                                    <\/div>\n            <\/div><div class=\"teeptrak-form-row\">                <div class=\"teeptrak-form-field\">\n                    <label>Goals<\/label>                    \n                                            <textarea name=\"message\" rows=\"3\"  placeholder=\"\"><\/textarea>\n                                    <\/div>\n            <\/div>            \n            <input type=\"hidden\" name=\"page_url\" value=\"https:\/\/teeptrak.com\/en\/opc-ua-companion-specifications-manufacturing-2027\/\">\n            <input type=\"hidden\" name=\"recaptcha_token\" value=\"\" class=\"teeptrak-recaptcha-token\">\n            \n                        \n            <div class=\"teeptrak-form-row\">\n                <button type=\"submit\" class=\"teeptrak-submit teeptrak-submit-full\">\n                    <span class=\"teeptrak-submit-text\">To book<\/span>\n                    <span class=\"teeptrak-submit-loading\" style=\"display:none;\">Envoi...<\/span>\n                <\/button>\n            <\/div>\n            \n            <div class=\"teeptrak-form-message\" style=\"display:none;\"><\/div>\n        <\/form>\n    <\/div>\n    <\/div>\n<p><script type=\"application\/ld+json\">{\"@context\": \"https:\/\/schema.org\", \"@type\": \"Article\", \"headline\": \"OPC UA Companion Specifications 2027: PackML, ISA-95, Euromap, MTConnect \u2014 interoperability guide for manufacturing IIoT\", \"description\": \"OPC UA Companion Specifications 2027: PackML (OMAC state model), ISA-95 (B2MML), Euromap 77\/82\/83 (plastics), Sercos (motion), MTConnect vs OPC UA, OPC UA Pub\/Sub vs Client\/Server, OPC UA FX (Field eXchange).
