Bridge PLCs to the cloud, without breaking the plant.
OPC-UA, Modbus, Siemens S7, Unified Namespace (UNS) topology, time-series storage, and air-gapped edge networks. For hardware startups whose pilot customers run real factories.
Rate $80 – $100 USD / hour · fixed-fee and retainer available
What you get
- Protocol drivers
- OPC-UA, Modbus TCP/RTU, Siemens S7, EtherNet/IP, BACnet, with test harnesses.
- Unified Namespace (UNS)
- topic hierarchy + governance, so every team subscribes to the same shape of data.
- Time-series storage
- InfluxDB, TimescaleDB, or QuestDB with retention policies, downsampling, and an open SQL query layer.
- Air-gapped edge
- gateway hardware profile, network segmentation, and the security review checklist.
- Realtime stream
- Kafka or NATS, with the right back-pressure and dead-letter handling for lossy industrial links.
