What this template does
A Python tick on the broker drives mixer, filler, and capper. MODBUS_SERVER and OPCUA_SERVER expose those tags on localhost. Client routes poll them onto Plant/#. PostgreSQL stores completed batches. An AGENT reads the namespace.
When to use it
A self-contained bottling lab — no extra simulator process. Point the client hosts at real PLCs when you have them.
