Install and Configure the SMART OPC UA Server - SMART System

The SMART OPC Unified Architecture (OPC UA) Server is installed automatically with the SMART System Software version 1.3.1 or later, for either Ubuntu 18.04LTS or 22.04LTS. In order for the OPC UA Server to begin running, you must configure SCADA settings on your SMART Controller.

1. To check the currently installed version of the SMART System Software, open the SMART Control Panel and check the Version text at the bottom of the navigation panel.
   
   
   If the text displays version 18-1.3.1 or later, or 22-1.3.1 or later, then the OPC UA server is installed.
2. In the SMART Control Panel, under the SCADA tab, set the Modbus Port to TCP and enable at least one alarm.
   Configuring SCADA settings creates the file /var/www/storage/scada.json.
3. Configure Secure Certificates for communication between your client and the SMART Controller.
   Secure Certificates may be installed on the SMART Controller in the directory /etc/ssl/private.
4. From a terminal, run the command systemctl start smart-opcua to start the OPC UA server.
