IA — Industrial Automation
Industrial Automation — the operational layer above DI. Four enums, one structured type. Loaded transitively by Machinery and every spec under it.
The "industrial automation" layer that sits on top of DI. Adds operational types — running / stopped state, operating modes, production counters — that DI's identification-focused model leaves out.

Loading
php
examples/ia/load.php
use PhpOpcua\Client\ClientBuilder;
use PhpOpcua\Nodeset\IA\IARegistrar;
$client = ClientBuilder::create()
->loadGeneratedTypes(new IARegistrar()) // pulls DI
->connect('opc.tcp://machine.local:4840');You rarely load IA directly — it comes in transitively with Machinery and every spec downstream.
