Configuring the OPC UA Connector

Kaspersky MLAD uses the OPC UA Connector to receive data over a protocol described by the OPC Unified Architecture specification.

System administrators can configure the OPC UA Connector.

The OPC UA Connector does not support a secure connection. If you want to use a secure connection to receive and send data, it is recommended to use additional means to secure the network connection (for example, use a VPN) or use another method to prevent unauthorized access to the communication channel.

To configure the OPC UA Connector:

1. In the lower-left corner of the page, click the  button.

   You will be taken to the administrator menu.

2. Select System parameters → OPC UA Connector.

   A list of options appears on the right.

3. In the Connection point field, specify the connection address.

   For example: opc.tcp://10.0.0.0:8001/freeopcua/server/.

4. In the OPC UA server connection timeout (sec) field, specify the time period (in seconds) that the OPC UA Connector will attempt to establish a connection with the OPC UA server.
5. Using the Browse button under the Configuration file setting, add a file containing settings for configuring the OPC UA Connector.

   To delete the connector configuration file, click the Clear icon (). To save the connector configuration file on your computer, click the Download icon ().

6. In the Historical data interval (sec) field, specify the time interval (in seconds) for which the OPC UA Connector requests historical data stored on the OPC UA server.

   Enter 0 if you do not need to download historical data. Enter -1 if you need to download all historical data.

7. In the Start of historical data period (YYYY/MM/DD HH:MM:SS) field, specify the start date and time of the period for which you want to download data from the OPC UA server.
8. In the End of historical data period (YYYY/MM/DD HH:MM:SS) field, specify the end date and time of the period for which you want to download data from the OPC UA server.
9. In the Size of historical data block sent by OPC UA server (numvalues parameter) field, specify the number of tags that will be transmitted in the historical data block sent to the OPC UA Connector from the OPC UA server.
10. In the Size of historical data block sent to Message Broker service field, specify the number of tags that will be transmitted in the historical data block sent from the OPC UA Connector to the Message Broker service.
11. Click the Save button.
