Every decision is made on an edge PC at the station, based on the last verified package delivered by Server. Production images never have to leave the station or the plant — analysis happens locally.
A station runs on recipes: different product variants can use a different configured inspection, and if a new model version causes a problem, the station can roll back to the previous one in a controlled way, without manual file changes on the machine.
Production also detects the loss of its own ability to inspect — if something prevents a reliable decision, the system flags it instead of silently letting the product through. Every inspection result goes into a local history and, over Modbus TCP, to the rest of the process — for example, to the line's PLC.
