OPC TWIN Method call #996

Closed ma3goul closed 1 year ago

ma3goul commented 3 years ago

Describe the bug I am trying to call OPC ua method using an Opc twin module deployed on a raspberry3 , The OPC UA server is running on a siemens S7-1500 PLC . On the OPC UA server I developed a simple function block that has a struct output containing a bool , an integer and an DTL : I succeeded to call this method using the twin microservices. But when I tried to set an output : struct of struct in the method the OPC twin module failed to connect to the endpoint and I got this error . What are the type of data supported by the OPC twin ?

Expected behavior Connect to the endpoint and call the method

Screenshots here the twin module logs :

[15:23:59 ERR Microsoft.Azure.IIoT.OpcUa.Protocol.Services.StackLogger] (Error) Skipped the type definition of "getDataFromJIG"."dataArray". Retry in next round. DataTypeNotFoundException 'Exception of type 'Opc.Ua.Client.ComplexTypes.DataTypeNotFoundException' was thrown.'

Thank you.

Custom structure datatypes are generally supported in the opc twin. From the exception it looks like there is a issue loading the dictionaries from the specific OPC UA server We have seen issues in the past with the complex types dictionaries of S7-1500. Would you have a chance to update the firmware on the S7-1500?

@ma3goul S71500 as OPC UA server able to send data tor IOT hub using OPC Publisher,

But now i need to send command from IoT hub to OPC UA server S71500 PLC, I configured OPC Twin Module but how this can be achieved......

@ma3goul would you be able to share a bit more part of the logs so we can get a bit more context on this issue?

Release 2.9.0 preview 2 of OPC Publisher was just released. It supports the OPC Twin API which can be invoked without cloud services. Documentation will be provided soon.
