Configuring data acquisition over the OPC UA protocol

To configure data acquisition using the OPC UA protocol:

1. Create the OpcUaClientSettings-0.json configuration file.
2. In the OpcUaClientSettings-0.json file, specify the OPC UA settings and their values in accordance with JSON syntax.
3. Put the configuration file into the directory /app/Core/config/transfer/opc_ua/client on the HW-IDS partition of the microSD card.

Sample configuration file:

OpcUaClientSettings-0.json

{

"id": 0,

"name": "Kaspersky IoT Secure Gateway 100 OPC UA Client",

"description": "Collects data from CNC by Kaspersky IoT Secure Gateway 100",

"url": "opc.tcp://192.168.177.7:4840",

"readingCycle": 1,

"policy": "Basic256Sha256",

"clientPkiData": {

"certificate": "opc-ua-client.crt",

"privateKey": "opc-ua-client.key"

},

"trustList": ["opc-ua-server.crt"]

},

"userCredentials":

{

"password": "0R20jN#yZd~zaLKe?2J#@~|YC"

},

"heartbeat": {

"id": 0,

"name": "Heartbeat",

"timeout": 60

},

"nodes": [

{

"id": 1,

"name": "Temperature",

"nodeId": "ns=1;s=VariableTemperature"

},

{

"id": 2,

"name": "Speed",

"nodeId": "ns=2;i=2045"

}

]

}

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).
