Example: OPC UA Data Source

Product: CODESYS OPC UA

The example shows how to configure a CODESYS data source in connection with an OPC UA Server. The example contains two projects, OPC_UA_SERVER and OPC_UA_CLIENT, with one application each.

Description

In the application under the Application_DataSource server, different values are written via Server_PRG and transmitted via the symbol configuration.

In the client, a Data Source Manager has been added in the application in order to read the sent data. In Main_PRG, the instance can be accessed directly.

Additional information

Important

  • The connection to OPC UA servers is possible only via an IP address and not a host name.

  • To establish secure server–client communication, the CODESYS Security Agent has to be used to generate a client certificate on the controller before the connection is established.
