Composable, modular automation systems are gaining traction in industrial environments as organizations adopt open interoperability standards for rapidly reconfigurable, plug-and-play production cells. Vendors, systems integrators, and manufacturers are developing common data models and interfaces to support modular cells that minimize downtime and accelerate changeovers. This trend is driven by reduced time-to-market and greater flexibility in multi-product operations.
Background
VDI/VDE/NAMUR 2658, which defines the Module Type Package (MTP) framework, enables seamless interoperability between modular automation units and central controllers, supporting vendor-neutral integration. The MTP framework allows production modules to be scaled or reconfigured without disrupting other system components, enabling responsive and flexible manufacturing . Recent analysis indicates that modular automation based on this standard can halve downtime, reduce automation engineering capital expenditures by 50%, cut lifecycle management costs by 20%, and decrease time-to-market by 40% 1How Modular Automation Is Helping to Create the Chemical Process Control Systems of the Future.
Europe, notably Germany, is advancing modular automation through Industrie 4.0 initiatives and funding incentives. In 2023, Germany allocated €3.8 billion to digital manufacturing, emphasizing modular automation. Europe represented 29.8 percent of global modular automation adoption in 2024, second to North America's 34.2 percent share2Modular Automation Market Size, Growth Outlook 2034.
Ongoing developments in interoperability frameworks further support the shift to modularity. OPC UA companion specifications and the emergence of OPC UA Field Level Communications extensions are enabling open, multivendor data exchange across devices and control levels. According to the German Mechanical Engineering Industry Association (VDMA), OPC UA is fundamental for Industrie 4.0 and enables plug-and-work interoperability across equipment manufacturers3Interoperability - vdma.org - VDMA.
Details
Packaging and automotive component manufacturers adopting modular cells are experiencing significant reductions in time-to-production, with deployments based on MTP and open interfaces shrinking timelines from months to weeks. Exact user data remain proprietary and undisclosed.
Open standards are gaining ground across the industrial ecosystem. The OPC Foundation's Field Level Communications initiative has enabled multivendor interoperability, demonstrated with UAFX connections among automation components from 20 vendors4OPC Foundation Showcases Industrial Digitalization Integrated Architecture at SPS 2022. Intelligent Systems has published an open reference architecture and integration interfaces under Apache 2.0 license for smart production modules, encompassing robotics cells, autonomous mobile robots (AMRs), palletizing, and transport modules with support for protocols such as MQTT and REST5Open Standards for Smart Production - Intelligent Systems AS.
Mobility-focused automation is also progressing. Fraunhofer IML has released an open-source implementation of the VDA 5050 standard for AMR systems, facilitating plug-and-play integration of heterogeneous vehicle fleets with central fleet management systems6Interoperability of systems - Fraunhofer IML.
Outlook
Standards organizations and industry consortia are strengthening modular automation infrastructure through companion specifications and interoperability testing tools. Forthcoming OPC UA updates-including enhanced state-machine modeling and PubSub quality-of-service features, slated for January 2026-are expected to improve reliability and enrich semantic integration across modular cells7January 2026 Manufacturing Engineering Standards: OPC UA Updates, Data.
Manufacturers and integrators are encouraged to leverage MTP-based modules and new open frameworks for enhanced modularity, while proactively addressing technical challenges such as cybersecurity, multivendor update management, and consistent performance validation. Evolving workforce skills toward multi-vendor interoperability maintenance and dynamic system configuration will also be essential.
