OPC Alarm Parameters are not collected at IoT hub

HI,
We have installed "Prosys OPC Simulation Server" on edge device and configured 6 tags for data collection (F101A, F101B,P101A, P101B,T101A,T101B) and Prosys simulation software , by default, as an In built tag (MyLevel) on which alarms are gnereated. We are able fetch the alarm tag associated parameters ( like severity , AckedState, Message, AcivityState) on client (Prosys UA Browser). However we are not able to read those parameters on IoT hub.

Enclosed is PublishedNode.json file and Log file that collects the raw data on IOT Hub from OPC server. Log file is collected from Functions -> monitor -> systemLogs

You may observe from the log file that all tags (F101A,...) are collected periodically, only myLevel.ActiviteState is collected , while other associated parameters like myLevel.message, mylevel. Severity, myLevel.SourceName are not collected

Thanks

Hello @HCLAZURECloudConnectedECOSystems-0579

We are able to fetch the alarm tag associated parameters ( like severity , AckedState, Message, AcivityState) on client (Prosys UA Browser).
What is the procedure or method followed to read the message on the client-side?

However we are not able to read those parameters on IoT hub.
could you please confirm on the data sent to the IoT Hub contains the required information which is read by the client?

Any documentation which you have followed or any architectural workflow would be helpful to understand this issue better.

IoT Edge-->IoTHub-->Azure Functions-->Prosys UA Browser ?is this the right architectural flow?

--> Prosys UA Broser is OPC Client Tool and after connecting to server , the data view and Event View tabs in that tool can be used to view the data and alarm parameters . we are able to read the alarm parameters in Data View and Event view tab in UA browser

could you please confirm on the data sent to the IoT Hub contains the required information which is read by the client?

--> the flow is Prosys UA Simulation server (on linux box)-> OPC Publisher (on linux box) -> Azure Functions (on cloud) -> IoT Edge(on cloud)

Let me know if you able to simulate the issue

Hello @HCLAZURECloudConnectedECOSystems-0579,

I wanted to understand if this issue is really with Azure IoT Hub or with Prosys UA Browser OPC Client Tool/
Could you please include the screenshots of the Prosys UA Broser OPC Client Tool, where the data is viewed and the issue area?

--> the flow is Prosys UA Simulation server (on linux box)-> OPC Publisher (on linux box) -> Azure Functions (on cloud) -> IoT Edge(on cloud)

You may want to mention the place of 'Azure IoT Hub' in the above flow?
