OPC UA License for cMT-SVR/cMT-FHDX (add-on)

Activation license that enables the **OPC UA Server** function on Weintek cMT X series models that do not include it as standard, such as the cMT-FHDX (HDMI output) and cMT-SVRX headless HMIs.

Once activated, the panel exposes its tags via OPC UA and becomes a standard data source for SCADA, MES, supervision systems, and IIoT platforms. No additional gateways are required.

**Key features**

- OPC UA server built into the HMI, OPC Foundation certified
- Tag exposure in read and/or write mode, with a customizable node structure
- Historical data support (OPC UA HDA)
- Authentication with username and password or X.509 certificates
- Easy configuration from EasyBuilder Pro, IIoT menu, OPC UA Server entry
- Works alongside the functions already included as standard: OPC UA Client and MQTT

**Typical applications**

- Integration of machines and plants with SCADA and MES
- Data collection for Industry 4.0 / 5.0
- Bridge between PLCs with proprietary protocols and OPC UA-based IT systems

**Notes**

- The license is tied to a single device.
- Please verify the compatibility of your model before ordering. On cMT X Advanced models with a display, the OPC UA Server is already included.
