THE BRAIN REVOLUTION
The industrial control system for teams and agents
A vertically integrated PLC cabinet. Describe a machine in plain language and Brain generates the control system, validates every change, guides commissioning, runs safely, and recovers from failures — autonomously.

HARDWARE
Ships as a cabinet. Built to last a decade.
A fully enclosed industrial cabinet -- controller, 220 I/O points, power distribution, emergency stop, status display, and the AI co-processor -- pre-wired and pre-tested. Mount it, connect it, describe the machine.

Pre-wired, pre-tested
64 RTD + 64 DI + 64 DO + 24 SSR + 2 PSU + 2 camera channels, terminated on labelled terminal blocks ready for field wiring.
VERTICALLY INTEGRATED
A new kind of PLC. Vertically integrated from the PCB to the AI agent, Interkey Brain replaces the SCADA stack, the HMI panel, and the engineering workstation with a single system that ships ready to run.

AI PLC AGENT
Describe a machine, ship a control system
Tell Brain what you're building. It reads the live system, writes an IEC 61131-3 program, creates an operator HMI, configures alarms, tunes PID loops, and starts the engine -- all streamed in real time. This is the engineering agent. Brain also has a commissioning agent for startup, a watchdog for monitoring, a responder for autonomous fault handling, and an optimizer for daily tuning.
See Agents →OP
Build a freeze dryer with 4 heaters on SSR0–SSR3, RTD0–RTD3 feedback, PID at 60°C, alarm if any heater exceeds 80°C.

FIVE AGENTS
Engineering, Commissioning, Watchdog, Responder, Optimizer
Five specialized AI agents share one tag system, one 5-tier safety model, and one audit trail. Engineering generates control systems from natural language. Commissioning verifies every channel. Watchdog scans health every 5 minutes. Responder reacts to alarms in real time. Optimizer learns from historian data daily. The closed engineering-to-operation loop the incumbents do not have.
See Agents →Step 1 · Generate
Engineering
Natural language to IEC 61131-3 programs, HMI, alarms, PIDs.
Step 2 · Validate
Commissioning
Channel-by-channel verification of every I/O point on startup.
Step 3 · Monitor
Watchdog
5-minute health scans across PLC, drivers, network, and cloud.
Step 4 · React
Responder
Real-time alarm response inside the Tier-3 safety envelope.
Step 5 · Learn
Optimizer
Daily tuning from historian data — PID, setpoints, schedules.

SAFETY BY DESIGN
Five tiers of AI authorization
Read operations are always allowed. Safety-critical actions require admin approval and explicit confirmation. Auto-lock after 3 Tier-3 actions in 60 seconds. Emergency stop endpoint kills all automation instantly. Full audit trail.

INDUSTRIAL RELIABILITY
When AI fails, the PLC keeps running
Hardware watchdog on every I/O board (2-second timeout). Software circuit breaker isolates AI without affecting PLC. Immutable audit trail in SQLite WAL mode. Full project backup/restore with one-click rollback. Degraded-mode operation: PLC engine, drivers, and alarm processing all run independently of AI, network, or backend.
