Brain Gateway

Coming 2027 · early access available

AI for the PLCs you already own.

Already running Siemens, Rockwell, Beckhoff, or CODESYS? Brain Gateway brings the same AI agent, the same 5-tier safety, and the same audit trail to your existing factory floor. No rip-and-replace.

Retrofit, Not Rip-and-Replace

Modernize without re-engineering.

Most factory floors have decades of working PLC code. Replacing it means months of validation, requalification, and risk. Brain Gateway sits beside your existing PLCs and adds AI capability over their existing protocols — read-mostly, sandboxed, and reversible.

What It Does

Read · Diagnose · Optimize

Read

always allowed

Mirror existing tags into Brain

→Reads tag values from existing PLCs
→Mirrors them into the Brain tag system
→Available to Brain AI, HMI, dashboards, MQTT
→No PLC changes required

Diagnose

tier 1-2

Analyze, suggest, document

→Brain AI agent analyzes incumbent PLC behavior
→Suggests improvements with full impact analysis
→Generates documentation from existing programs
→Never writes back without explicit approval

Optimize

tier 3, with approval

Adjust, with full sign-off

→Setpoint adjustments via existing protocols
→Schedule and recipe changes
→Always under 5-tier safety authorization
→Always reversible via incumbent system

Protocols

Speak every major industrial protocol.

Profinet

Siemens, Phoenix Contact, KUKA

EtherNet/IP

Rockwell, ODVA-compliant

BACnet

Building automation, HVAC

Modbus TCP / RTU

Universal industrial

M-Bus

Energy and utility metering

KNX

IoT and cloud bridges

Siemens proprietary protocol

Gateway Hardware

Pure protocol bridge. No PLC engine.

→ 4-8 PoE Ethernet ports (configurable)
→ DIN-rail mountable
→ No physical I/O — pure software bridge
→ Brain OS with read-mostly Gateway Safe Mode
→ Same Brain AI agent, same 5-tier authorization
→ Compatible with Brain Cloud subscription for fleet management

Gateway Safe Mode

Same AI. Different default.

Brain Gateway runs the same Brain AI agent — but in a stricter default authorization mode. All write operations to incumbent PLCs require explicit operator approval. No autonomous control writes. No setpoint changes without sign-off. The agent is a diagnostic and advisory layer; the incumbent PLC remains the system of record.

Use Cases

When Gateway makes sense.

Brownfield modernization

Existing factory with 20+ year-old PLCs. Add AI without requalification.

Mixed fleet

Some Brain Pro cabinets, some legacy Siemens. Unified fleet dashboard via Gateway.

Compliance bridging

Add audit trail and 5-tier safety on top of existing automation.

Pilot before full migration

Prove Brain AI value on existing hardware before buying full Brain cabinets.

Migration Path

Start with Gateway. Move to Brain Pro when ready.

Today

Gateway

AI advisory layer over existing PLCs. Zero risk, zero changes.

Next year

Hybrid

Brain Pro on new machines, Gateway on existing fleet. Unified fleet dashboard.

End-of-life

Replace

When incumbent hardware reaches end-of-life, swap to Brain I/O. AI agent and operator workflows already in place.

Pricing & Availability

Brain Gateway — €1,500 target. Coming 2027.

Brain Gateway enters early-access in late 2026 with selected partners. General availability 2027. Pricing target: €1,500 per Gateway unit. Each Gateway connects up to 8 incumbent PLCs.
