PLC retrofit
Bring legacy control into the AI era without a rip-and-replace. We add intelligence beside your proven PLC — not on top of it.
Your PLC works. The problem isn't the controller — it's that it can't see, learn, or talk to the cloud. We bridge that gap with a Pi/MCU node that sits alongside, reads the same signals, and adds the layer your line was missing.
Safety-rated control stays exactly where it is, on certified gear. The smart layer rides beside it, so you modernize without re-validating what already passes.
How an engagement runs
Tap, don't replace
We read your existing I/O and fieldbus (Modbus, OPC-UA, EtherNet/IP) without touching the safety loop.
Add the smart layer
On-device vision, predictive maintenance and dashboards run on the Pi node, beside the PLC.
Bridge to the cloud
Signed OTA updates, MQTT to your dashboards, and brownfield gear finally reaching modern tooling.
Deliverables
Other ways we help
Automation consulting
Vendor-neutral scoping. We tell you what to automate, on what hardware, and — honestly — where a PLC still beats a Pi.
Pi integration
Design, build and deploy smart control on industrial Raspberry Pi & MCUs — the open, documented stack you actually own.
Support & maintenance
A controls engineer on call, signed OTA updates, and monitoring — so the smart layer keeps running long after deploy.
