Argus
The edge computer that runs Acaysia.
CPU, GPU and FPGA in one enclosure, installed beside your PLC.
-
Central processing unit
CPU
The plant side
Talks to the PLCs you already run, keeps the historian and retrains the models on-premises.
-
Graphics processing unit
GPU
The optimizer
Every control cycle, it simulates thousands of candidate trajectories and picks the best.
-
Field-programmable gate array
FPGA
The timekeeper
Deterministic timing for the watchdogs and the hand-back to your PID in under 100 ms.
Hardware
Built for any process, in any plant
The Acaysia Control System
Argus, our edge compute appliance, in development. MPPI optimization for physical processes, drop-in deployment, millisecond failsafe, continuous learning.
-
CPUCentral processing unit The plant side
Speaks OPC UA and EtherNet/IP to the PLCs you already run, keeps the historian, serves the operator dashboard, and retrains models on-premises with versioned rollback.
-
GPUGraphics processing unit The optimizer
Every control cycle, it simulates thousands of candidate control trajectories on the process model and picks the best: MPPI on the AcaysiaRT GPU runtime.
-
FPGAField-programmable gate array The timekeeper
Deterministic timing, independent of the software above it: the watchdogs, the health monitors and the hand-back to your PID in under 100 milliseconds.
Deployment journey
Shadow · Advisory · Closed loop
From observation to optimization, in controlled stages.
Control is handed over in stages. The system runs in shadow and advisory first, so it never gets more autonomy than it has earned.
-
01Observes
Shadow mode
Install the edge unit near the PLC and connect over standard protocols. The system observes reactor dynamics for 30 days, learning behavior without touching control, and compares its predictions against actual PID performance.
-
02Recommends
Advisory mode
The system provides optimization recommendations while operators maintain full control. Review predictions, build confidence in the model and refine safety constraints to plant-specific requirements.
-
03Controls
Closed-loop control
Autonomous operation within your defined safety envelope. The system co-manages control with PID and reverts automatically on any fault or operator request. Full audit trail and event logging maintained.
-
OngoingImproves
Continuous optimization
Models improve with every batch cycle. On-premises retraining with versioned rollback improves performance continuously while maintaining safety guarantees.
Integration
Detailed specifications under NDA
Works with the infrastructure you already have.
Argus sits next to your PLC and respects every interlock it already has. OPC UA and EtherNet/IP connect to the PLCs you already run, with IEC 62443 cybersecurity considerations throughout. No rip and replace.
