And just confirm me one more thing that is .Net mandatory if I am not using Webstation.

[naman28]

Is there a specific reason to try and connect to this utility?
Because I am able to connect to the OPC Server using Matrikon.

I am working on a VM (RDC) that uses windows 10.

[naman28]

And also when i am using matrikon to check opc da connection then it is working fine there but not in rapid scada.

And also one of the server from which I am able to connect in that there is a subfolder under which my tags are present I am not able to open that folder as soon as I click on the ‘+’ button the software hangs and I can’t click on anything inside rapid scada.

[naman28]

Ok one more thing when i am trying to connect to OPC DA Server I am getting a list oF DA Servers when i cilck on Select Button but I can’t connect to all the server like i have 4 DA servers list and i am able to connect to only one of them.

Can you list down some possibilites as to why this is happening?

[naman28]

Hey!

I have successfully connected my DA server with Rapid Scada now while subscribing to tags do I have to manually go and click on each tag to add it under subscription folder?

I have around 3000 tags and it would be highly tedious to do that is there any alternative way?

[naman28]

Did that still not working.

[naman28]

No there are no errors in the DrvDsOpcUaServer_OpcUaServer.log file.

When I connected using the endpoint wherein instead of using my host name I used my IP address then it got connected with Neuron but not with the host name.

But when I am using the endpoint with IP (opc.tcp://172.20.10.2:62541/RapidScada/DrvDsOpcUaServer) then it is not connecting with other PC outside my network.

In UA Expert it is showing this error: Could not connect to server:BadHostUnknown

Hi all,

I am trying to bridge OPC UA to MQTT with Neuron and EMQX.
Neuron is a industrial IoT connectivity server that can connect to a wide range of industrial devices using standard or device-proprietary protocols.

So what I did was I had a OPC DA server and I converted it to OPC UA using the Rapid Scada Data Source so when I am providing the endpoint like for eg. opc.tcp://mycomp:62541/RapidScada/DrvDsOpcUaServer
then it is not connecting with Neuron I don’t know why. It is successfully connecting to my UaClient but not with Neuron.

And one more thing does this endpoint works only on localhost or can we use it on different network or device?

[naman28]

It worked!
Thank you!.

[naman28]

Where can I get the user and password for connecting my OPC UA server as a Data Source to Ua Client such as UaExpert while converting OPC DA to UA. Every time it shows me wrong user or password while connecting to UA Client.
