ThingsBoard OPC-DA

Question

thingsboard 会连接到远程 OPC-DA 服务器吗？如果是这样，您如何配置 opc-config.json 以连接到 IBA？

我在配置中尝试了几个不同的输入，但网关没有发回任何值

这是我在日志中看到的错误：

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

目前不支持 OPC-DA。 ThingsBoard 支持更新版本的协议 - OPC-UA。目前我们的路线图中没有支持 OPC-DA 的计划，但是，由于这是一个开源项目，请随时贡献力量。
