The OPC UA connector does not read the folder tree created by the M251 PLC correctly.

[aramosf1966]

I need to connect the Thingsboard platform to the Schneider M251 PLC using the OPC UA protocol that is supported by both the Client-Server. The OPCUA connector is already configured and in the connector mapping part it only reads the tree folders and does not read the variables and therefore there is no telemetry.
I don't realize where the error is. Could you help me??
Thank you....

}
],
"timeseries": [

"key": "temperature °C",
"path": "${Root\.Objects\.Device1\.TemperatureAndHumiditySensor\.Temperature}"

@aramosf1966 Probably #1555 will help you, as I have these PLC models connected.
Appears that you have malformed config JSON.

Check my screenshots on the issue.

Hello..I just saw your suggestion to find the error that I must have in the json of the UA connector to connect the Schneider M251 PLC to the Thinsboard Platform. I have not been able to solve it yet. I will try your suggestion next Monday. I will send you my json file of the connector and perhaps you can see where I have the error. Thank you very much for the help.
