Independent consulting and implementation for SAP Digital Manufacturing, shopfloor connectivity via OPC UA and MQTT, and AI-based object recognition in manufacturing.
From the machine to the cloud — manufacturing data becomes traceable decisions.
Cloud MES — from requirements analysis through the asset model to productive operation. Integration with SAP S/4HANA and SAP ERP via SAP BTP and Cloud Integration.
Connect machines reliably: OPC UA, MQTT with Sparkplug B, SCADA and edge gateways. Clean ISA-95 data models instead of data silos.
Automatically check parts, defects and completeness — results flow back via OPC UA directly into MES systems such as SAP Digital Manufacturing.
Vendor-neutral consulting for SMEs: from around 190 MES systems on the German market, find the reliable, effective and cost-efficient one — and accompany the rollout together with the vendor.
The market is hard to navigate: Germany alone has around 190 MES systems with very different feature spectrums. MDVS advises vendor-neutrally — we find the system that truly fits your processes, not the one with the loudest marketing.
Operational stability, solid references, reachable support and the long-term viability of the provider.
Fits your processes and covers exactly the functions you need — without overloading you with unused modules.
Realistic total cost of ownership (TCO) across licence, operation and maintenance — right-sized instead of over-engineered.

Not every plant needs a two-year programme to finally see what happens on the shopfloor. MESlight is the in-house product of MDVS, built on SAP CAP and Fiori Elements — order execution, machine data, andon and OEE for plants that want transparency without rolling out a corporate landscape.
As a solid bridge until SAP Digital Manufacturing goes live — or permanently, for plants that do not need a corporate-scale MES. No extra framework that nobody will maintain five years from now.
From the first requirements capture to stable operation: a structured approach based on SAP Activate, in which MDVS takes the role of architect, developer or project lead — individually or end to end, as needed.
Requirements analysis, process capture as BPMN, as-is/to-be and a solid scope.
Asset, structure and indicator model, plant/resource/work center, SFC lifecycle and routing.
Connecting SAP S/4HANA and SAP ERP via SAP BTP / Cloud Integration, including master data.
Configuration, Production Operator Dashboard (POD), Groovy scripting and integration testing.
Hypercare, OEE and analytics evaluation as well as training for users and administrators.
The link between the line and the MES determines data quality. MDVS connects machines across vendors, models the data to ISA-95 and ensures events reliably arrive where they are needed.
OPC UA including address space mapping, connecting PLCs such as Siemens S7-1500 (DB blocks) and SAP Plant Connectivity (PCo).
MQTT with Sparkplug B: well-designed topic structure, birth/death certificates and store-and-forward for resilient data flows.
Ignition SCADA, edge gateways and protocol bridging on industrial PC or Raspberry Pi — close to the machine.
Modelling to ISA-95 and B2MML as well as the asset/structure/indicator model for SAP Digital Manufacturing.
Certificates, network segmentation and in-house CA. Sensitive process and image data can remain entirely within the plant.
Machine data becomes a machine logbook, OEE metrics and dashboards — the basis for decisions.
Cameras capture, AI evaluates, OPC UA connects, the MES decides. Images become actionable events in the production process — in real time and fully traceable.

Result in the MES (SAP DM)
Inference runs locally on edge hardware (e.g. industrial PC or Jetson) — image data never leaves your plant. Only the result is handed to the MES: OK/NOK, class, confidence and timestamp. This keeps quality data audit-proof within the production context.
Designed end to end from the field to the cloud — AI inference sits exactly where the machine and the MES meet.
As developer, architect or project lead — whatever your project needs right now.
Analysis, target picture and solution design for shopfloor, MES and integration landscapes.
SAP Digital Manufacturing, BTP / Cloud Integration (CPI), OPC UA and MQTT connectivity.
REST services, endpoint routing and API management for distributed Industry 4.0 scenarios.
Scrum, Kanban and SAP Activate — coordinating teams and external service providers.
Condensing machine data into reliable KPIs and production dashboards.
Integrating heterogeneous technologies, edge deployments and stable operation within the team.
MDVS IT-Solution is an independent engineering practice for manufacturing IT. For over 25 years Gerald Kliem has been connecting the shopfloor with SAP — from SAP MII and SAP ME to SAP Digital Manufacturing, SAP BTP and SAP S/4HANA.
As a technical consultant, architect and developer he works close to the code and close to the line: OPC UA, MQTT, SCADA, clean data models — and now AI object recognition as a closed loop with the MES.
Production projects no longer stop at the border. Plants, supply chains and teams are spread across Europe — and IT has to keep pace. With international project experience I support the IT of manufacturing companies even when the production process takes place in Poland or the Czech Republic — on site, remotely and in close coordination with local teams and vendors.
Whether a feasibility study, an architecture review or implementation — describe your project briefly and we'll find the right starting point.
