Connected Plant
The two ways a machine talks: measurement that arrives, and control that is sent.

Records
IoT Gateways
The box between the plant network and this platform. A gateway rather than a direct device connection because that is how it is built — sensors do not have credentials.
Open
Records
IoT Devices
Sensors, meters, counters, cameras and readers, each bound to the machine it measures.

Signals
What a device measures, one row per quantity. The scaling lives here because it is a property of the measurement — applied downstream, every consumer has to know it and one of them eventually will not.

Readings
The series. A sensor that returns a value it does not believe is worse than one that returns nothing, which is why the quality flag is on every row.

Alert Rules
A threshold, and how long it has to be true. Without the second, every rule fires on a single noisy sample and everybody turns alerting off.

Alerts
What fired, with the threshold AS IT WAS. A rule changes; the alerts it already raised keep the threshold they were raised against.

PLC Controllers
Writes are OFF by default, and that is deliberate: a write to a running machine is a physical action, and the safest configuration is the one where a misconfigured screen cannot take one.

PLC Tags
A memory address in a machine. The min and max are enforced on THIS side of the network, where the error message can say why.

Tag Bindings
What a tag MEANS, and the reason this integration is configuration rather than code. "DB10.DBW4" is meaningless; bound as "good count for PRESS-02" it feeds OEE, confirmations and kanban without anybody writing a transformation.

PLC Writes
Every value this platform sends to a machine, requested and approved separately, with the old value recorded. This is the table an auditor asks for after an incident.
