ThingsBoard OPC-DA

Will thingsboard connect to a remote OPC-DA server? If so how do you configure the opc-config.json to connect to an IBA?

I've tried several different inputs in the config but the gateway is not sending back any values enter image description here

This is the error i see in the log:

me@thingsboard:/etc/tb-gateway/conf$ cat /var/log/tb-gateway/tb-gateway.log | grep ERROR 2017-10-25 13:42:00,900 [main] ERROR o.t.gateway.util.ConfigurationTools - Failed to load class org.thingsboard.gateway.extensions.opc.conf.OpcUaConfiguration configuration from opc-config.json 2017-10-25 13:42:00,902 [main] ERROR o.t.g.e.opc.DefaultOpcUaService - OPC-UA service configuration failed! 2017-10-25 13:42:00,929 [main] ERROR o.s.boot.SpringApplication - Application startup failed

Solution

  • The OPC-DA is not supported at the moment. ThingsBoard supports newer version of the protocol - OPC-UA. At the moment there is no plan to support the OPC-DA in our roadmap, but, since this is open-source project, feel free to contribute.
