OPC UA Server

[sperate]

Hi all,

some of you managed to make the new OPC UA feature of version 6.X to work.
Could someone explain me how to do it ? What are the basics ?
What’s necessary after server activation in the Data Sources ?
What url / IP:port is used to reach it ?

Many thanks !

[Mikhail]

Hi,

You can find the URL in Logs, DrvDsOpcUaServer_*.log
For example, opc.tcp://mycomp:62541/RapidScada/DrvDsOpcUaServer

Ok, thank you very much !! Now it works !!

I’ve moved the logs on a RAM Disk as explained on your install. process documentation.
But what is the standard place to get the logs if they are not on the RAM Disk ?

But what is the standard place to get the logs if they are not on the RAM Disk ?

If log directory is not specified in ScadaInstanceConfig.xml, logs are written in subfolders under applications, for example, SCADA\ScadaServer\Log

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.

By default
Username: opc
Password: scada
You can change them using the data source properties form.

[Mikhail]

Password here is encoded.

AutoAccept = true
ConfigFileName = DrvDsOpcUaServer.xml
DeviceFilter = 
Password = B9D0F030265751578B00E9801C69320C
Username = opc

Thank you!.

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?

Hi,
Are there any errors in log files?
Rapid SCADA OPC UA server can be accessed remotely.

If you need to publish OPC DA data to MQTT, you can try a Communicator data source that uses the DrvDsMqtt driver.

[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

[Mikhail]

You should enable incoming TCP connections to the port 62541 in the firewall settings.

[naman28]

Did that still not working.

> Could not connect to server:BadHostUnknown
This error means that the computer where the OPC server is installed cannot be found by the client.
