Layered platform
One codebase, published as a cloud service and an on-site server. Controllers are read by an optional edge runtime (ControlLogix over EtherNet/IP CIP, PLCnext over gRPC), which buffers through link outages and feeds the server, or, for ControlLogix, by the site server directly (early access). Real-time monitoring runs over a server-driven UI, drawn by a thin browser or csy CLI client.
Advisory-only AI
AI reads tags, alarms and history, explains plant state and can propose an action for an operator to review; it never executes one. Hard interlocks live in deterministic controller logic and hardwired safety relays — never in the server or AI path.
Simulation-first
A data-driven Sim runtime stands in for physical PLCs, so you can build and evaluate a site before a single wire is landed.
One UI tree, many renderers
A semantic UI tree renders in the browser, the csy CLI, and (roadmap) WinUI3 over a single wire format.
