I have an issue where I am not sure whether it is expected behavior or not.
I recently used the OPC UA adapter from HiveMQ edge to connect to an OPC UA server. I expected the adapter to publish all OPC values each publish cycle. However, it only publishes values that changed on the OPC UA server.
Maybe I missed something, but it would be useful to have an option to update all values regardless of whether they changed on the OPC server or not since e. g. Dashboards need continuous updates. Thanks for your help!
I understand you’re using HiveMQ Edge. The OPC UA adapter in HiveMQ Edge allows you to configure the publishing interval for northbound (OPC UA to MQTT) data using the publishingInterval property, which defines how often the adapter checks for data updates from the OPC UA server: HiveMQ Edge Protocol Adapters - OPC UA.
However, the adapter currently publishes MQTT messages for data changes detected on subscribed OPC UA nodeIds. There is no option at the moment that the adapter can be configured to publish all values on every cycle, regardless of whether the values have changed.
If you require continuous updates for all values (even if unchanged), please feel free to request this new feature by submitting the New Feature Request form..
