Configuring data acquisition over the OPC UA protocol
To configure data acquisition using the OPC UA protocol:
- Create the
OpcUaClientSettings-0.jsonconfiguration file. - In the
OpcUaClientSettings-0.jsonfile, specify the OPC UA settings and their values in accordance with JSON syntax. - Put the configuration file into the directory
/app/Core/config/transfer/opc_ua/clienton theHW-IDSpartition of the microSD card.
Sample configuration file:
OpcUaClientSettings-0.json
{
"id": 0,
"name": "Kaspersky IoT Secure Gateway 100 OPC UA Client",

},

},

}
]
}
To edit files in JSON format, we recommend using a text editor that supports JSON syntax highlight. This will help avoid potential errors (for example, unbalanced braces).
