OPC UA Gateway for CNC and Industrial Machines

SmartConnect IIoT is an OPC UA gateway for CNC and industrial machines. It collects machine data from CNC controllers and PLCs and exposes it through an OPC UA interface for MES, SCADA and industrial clients.

What is OPC UA?

OPC UA (OPC Unified Architecture) is a widely used industrial interoperability standard for exchanging data between machines, controllers and software. It defines a consistent way to represent data (an address space of nodes) and to read, write and subscribe to that data over a network, independent of any single vendor.

Because so many MES, SCADA and industrial applications support OPC UA, it is a common way to make machine data available across a factory.

Why manufacturers use OPC UA

• A vendor-neutral, widely supported industrial standard.
• A consistent address space for machine and controller data.
• Read, write and subscribe (data-change) access for clients.
• Broad support across MES, SCADA and industrial software.
• Transport security and authentication built into the standard.

SmartConnect and OPC UA

SmartConnect connects to your CNC machines and controllers, collects the configured data, and exposes it through OPC UA. Client applications connect to SmartConnect and read the machine data as a structured OPC UA address space — without needing to understand each machine’s native protocol.

Machines	CNC controllers and PLCs
SmartConnect	Collects and structures machine data
OPC UA	Exposes the data to OPC UA clients
Clients	MES, SCADA and industrial applications

CNC → SmartConnect → OPC UA → application

This is the core pattern: SmartConnect handles machine connectivity and CNC data collection, and OPC UA carries that data to the application. It underpins machine monitoring, SCADA and MES integration.
