NEO PI

When the format is proprietary: codecs

Not every manufacturer follows a standard. A codec is a declarative expression that translates a vendor’s raw payload into measurements — configured through the interface, tested before saving, with an AI-assisted draft from a sample payload. In practice: equipment sending {"temp_raw":247} starts recording 24.7 °C without a line of code and without waiting for a release.

Data goes out too: forwarding

Forwarding rules deliver readings to external systems by webhook (HMAC-signed, token-authenticated) or MQTT publication, with optional payload transformation, batched delivery, a durable retry queue and automatic shutoff when a destination keeps failing.

The electronic batch record drives production: procedures, work orders, in-process controls. Historically, process values reach that record by manual transcription — an operator reads the display and types. That is simultaneously the slowest and the most fragile step of the record: subject to misreading, typing errors and delay, and it demands second-person review precisely because of that.

With NEO PI, the value comes from the historian:

• the in-process control in NEO EBR reads the measurement directly from the corresponding asset in PI
• the value arrives with its origin timestamp and quality, not the time someone typed it
• the batch record points to immutable data, traceable back to the raw event
• out-of-range deviations stand out against the full history, not an isolated point

EBR consumes PI through the Read API: a navigable namespace (site/area/asset/measurement), current-value reads, history queries with aggregations, and live event subscription over SSE — all authenticated by scoped read keys that limit each consumer to exactly the assets and measurements it should see.

That API is an open protocol, and nothing about it is NEO-specific. NEO W&D reads dispensing weights from it the same way, and any third-party system — MES, LIMS, ERP, a BI tool — consumes it over plain REST and SSE. PI is a layer your plant owns, not a captive component of one suite.
