Software development for manufacturing
Custom MES, ERP-MES integration, OPC UA / MQTT shop-floor connectivity and ESPR Digital Product Passport pipelines for Hungarian OEMs and Tier 1-2 suppliers. IATF 16949 traceability, CSRD ESRS data module, NIS2 important-entity compliance in one codebase. Last updated 2026-05-04.
TL;DR
- The Hungarian automotive ecosystem (Audi Győr, Mercedes Kecskemét, Suzuki Esztergom + ~700 suppliers) runs on IATF 16949:2016 traceability across the chain.
- ESPR (Reg. 2024/1781) full application is 2026-07-19, battery DPP mandatory from 2027-02-18.
- The post-Omnibus CSRD threshold: 1000+ employees and EUR 450M+ turnover from 2027. Tier 1s usually qualify.
- NIS2 Annex II places manufacturing under important-entity rules — fines >= EUR 7M or 1.4%.
- Project ranges: HUF 8-80M depending on scope, EU-region or on-prem deploy.
Pain map — what manufacturing IT directors deal with right now
Concrete, named problems from Hungarian automotive and engineering plants.
OEM kanban signal lags hours behind the shop floor
An Audi / Mercedes / Suzuki order arrives in SAP, but the Siemens S7-1500 PLCs don't see it directly. We build an OPC UA + MQTT bridge so the kanban appears on the line within seconds, with batch-level traceability.
ESPR Digital Product Passport — the data is in 4 silos
After the 19 July 2026 ESPR full application date, item-level material composition, dismantling and repair info has to live behind one QR. PLM (Teamcenter / Windchill), ERP (SAP), supplier declarations (IMDS) sit in separate silos today. We aggregate and emit a GS1 Digital Link-compatible DPP JSON.
IATF 16949 audit traceability incomplete
IATF 16949:2016 demands a PPAP / FMEA / SPC trail down to the per-batch part. An Excel-based process collapses in minutes during a third-party audit. We build an audit-trail layer with immutable change records linked to the production order.
CSRD ESRS data lives in an Excel matrix
ESRS E1 (climate) and E5 (circular economy) data points usually sit in Excel macros today. XBRL Taxonomy submission needs structured backend storage. We deliver that, pulling from line-level energy meters and HVAC (Modbus / BACnet) automatically.
NIS2 OT incident reporting in 24 hours
Hungary's Act LXIX of 2024 and NIS2 Art. 23 require a 24h early warning + 72h incident report on the OT side too — most plants haven't drilled this. We stream SCADA / MES events into the SOC, with auto-classification and a pre-filled report template.

| Rockwell Plex MES | REST + Plex API | Cloud-native MES, common at Tier 2-3 automotive suppliers. |
| AVEVA Wonderware (Schneider) | OPC UA / MQTT / SuiteLink | Classic process SCADA, also food and pharma. |
| Siemens S7-1500 PLC | Profinet / OPC UA Server | Built-in OPC UA Server + PubSub MQTT/UADP for shop floor data. |
| Allen-Bradley CompactLogix / ControlLogix | EtherNet/IP + CIP | Rockwell PLC, OPC UA Edge Server toward the cloud. |
| Beckhoff TwinCAT 3 | ADS / OPC UA / MQTT | PC-based control, real-time on Linux and Windows. |
| IMDS / CDX (material declarations) | XML import / web service | Supplier material data in automotive — basis for RoHS / REACH / DPP. |
| PTC Windchill / Siemens Teamcenter PLM | OData / REST / SOAP | Item-level BOM + ECO change management, source of DPP. |

Manufacturing — frequently asked
The Hungarian automotive ecosystem — Audi Hungária (Győr), Mercedes-Benz Manufacturing Hungary (Kecskemét), Magyar Suzuki (Esztergom), plus Bosch, Continental, ZF, Schaeffler suppliers — runs on IATF 16949:2016 across the Tier 1-2 chain. We build the software layer that takes an SAP order and pushes it through to the shop floor PLC: per-part traceability, real-time kanban over OPC UA, batch-level serial-number tracking. We typically slot in around an existing Siemens Opcenter or Rockwell Plex MES.
