OPC UA properties in Thingworx Composer

[augmentor]

Hi community,

I have an OPC UA server running on my network, which publishes a number every second.

I can see the value with UA Expert after inputting the opc URL.

However when trying to do the same with Thingworx composer, it doesn`t work yet.

Heres my OPC UA Remote Thing configuration: (Picture attached)

All I changed was the ConnectionAdress, the productURI (is there a specific value I have to add?) and I added a property Number, that I want to read the value with. However it doesn`t connect and I can not see the number.

Is there anything else I have to configure or did I do something wrong?

As I said I just had to input the URL to UA Expert and immediatly saw the changing number so I reckon it should be similarily easy with Thingworx Composer.

Thanks!

Hi @augmentor.

Are you using the OPC UA Client from the Marketplace?  Which version of ThingWorx are you running?

We will need to see more of your configuration to provide any guidance.

Yes I am using the client you are referring to and the version is ThingWorx 8.2.2-b167.

I used the OPCUAEndpoint template for my Thing and I changed the ConnectionAdress to my opc server adress as well as added an integer property that I want to be changed by the number the server is publishing every second. How would I configure the integer property so that it reads the value?

It seems that the server is not connecting.

I attached two pictures of my thing configuration.

Thanks

MQTT for example has a Configuration tab in Composer, but OPC UA doesn`t.. So I`m not sure how to configure it except the Connection adress.

Hi @augmentor.

Apologies for the delay.

Did you install the .jar and config.json on the client side (OPC server)?  You may need to check the parameters in the config.json file.  You can find more information on this in the documentation available for this extension on the marketplace.
