Hi,
I believe that you installation target is not compatible with the commands used by Kura to manage the networking/firewall. Probably there is also some meaningful error in the Kura.log or Kura-console.log file in /var/log.

Maybe have a look at those files.

Is it possible to have more details on your target device and operating system?
Which Kura binary did you install?

Best regards,
Matteo

I don't see anything special in kura-console.log. Maybe kura.log can be more helpful. Could you share it?

Hi,
as you can see from the log there is an issue invoking iptables in your target. Maybe some missing modules or something like that.

If you don't need networking, you may try to install the NN version of Kura.
Otherwise you will need to update your image to match Kura's requirements or you'll need to update kura codebase to support your linux flavour.

Best regards,
Matteo

Hi, are you able to ping internet from the device?
Is networking properly set?
Is the device capable to resolve names to ips?

You may want to have another look to the Kura.log, Kura-console.log or even also to your browser log to figure out what is going on.

Hi,
it depends on the component. For example the Heater, once installed, it auto starts.
If you are installing the example publisher, then it is a factory that needs to be instantiated using the + button in the left side of the page.
If the component installed is a driver, you need to instantiate it in the drivers and assets section.

Matteo

Is modbus package listed in packages tab?

Please have a look in kura.log and kura-console.log if there is any type of error.
You can also access the OSGi console and try to debug to understand if there is some sort of error that is showing up there.

That is not a driver.
It's the old (and probably deprecated) version of the modbus protocol.
It does not interfaces with drivers and wires.

At this time there is no official driver available.
A third party provided an implementation: https://marketplace.eclipse.org/content/esf-modbus-driver
Be careful that, to install, you have to accept an EULA

That is user responsibility to open the needed firewall ports either using Kura (if supported) or directly acting to the firewall of your host system.

Hi,
I suggest to have a look at the firewall to see if the configuration is correct. Make sure that the service is up and running.
Maybe you can also try another port, just to make sure.

Hello,

I would suggest you to perform the following steps:

1. Open port 1234 (or the port on which the server is listening on) in Kura firewall and try to connect using an external OPC-UA client, to verify that the server is up and running.

2. The

UserTokenPolicy with UserTokenType.UserName

message can indicate that you are providing username/password to a server that does not require authentication. In order to stop sending username and password, try clear the corresponding parameters in driver configuration (they should be blank for disabling sending credentials).

3.

 Connection refused: localhost/127.0.0.1:1235

can mean that no process is listening on port 1235, using port 1234 was probably correct.

Let me know if it works,

Best Regards,
Nicola

3) One thing i want to ask that i created opcua asset and their i created channels which is connected to wire graph and in wire graph their is logger so where i will see the logs or my data which i created in opcua asset i think this url (localhost/127.0.0.1:1234) will show my data if i am wrong please correct me. right now this is not opning??

Hello,
According to the document OPC-UA server simulator bundle is install in ESF. It will create a simulated OPC-UA server that exposes some sensors (light, temperature and water sensor) and some actuators (buzzer, led and fan). So where i can see all these data, and how we can change the value of these data??

From your answer 2 I assume you are trying to connect to http://localhost/127.0.0.1:1234 with some HTTP client (e.g a web browser), that request will not be served by the OPC-UA server but by the embedded Jetty web server instance.
If a request fails with code 2150891520, it should mean that you are trying to access a node that does not exist on the server (a node with the requested id cannot be found by the server).
The good news is that the fact that you can see this error implies that the driver was able to successfully connect and authenticate with the server, so firewall and global driver settings should be ok.

The next step is configuring asset channels.
For this purpose, I would suggest you to try connecting to the OPCUA server with a graphical OPCUA client (e.g a desktop or smartphone app), browse the server nodes with that and determine the the ids of the nodes you are interested reading/writing.
Once you discovered these node ids, you can use that information to configure the OPCUA driver channels.

I'm sorry but I cannot provide support for the tutorial you mentioned, as it is related to a commercial product.

Regards,
Nicola

Hello Nicola,

Thank you so much for your valuable suggestions, now I able to getting the data in data tab of opc-ua driver but one thing i want to ask for h2db service i created h2db server but i am not able to access the server in my web browser, This is the document which i am following-->https://eclipse.github.io/kura/builtin/h2-database.html

The kura is install in my device i connected it through wifi ip, but i am not able to access http://192.168.42.5:9123/

I checked firewall connection also, i change this -webPort 9123 -webAllowOthers -ifExists port to 9124 but result is same

Please give me some hint about this and thank you again for your quick reply.

Thanks and Regards,
Abhi

Hello,

I wouldn't know what's going on.
Configuring the firewall to allow TCP connections to TCP port 9123 and configuring the DbServer instance as follows should be enough:

db.server.enabled -> true
db.server.type -> WEB
db.server.commandline -> -webPort 9123 -webAllowOthers -ifExists

You can check if the server is listening on port 9123 by running curl directly on the device, try the following command:

curl http://localhost:9123/

If curl is not available you can try the wget, or try installing it.

If you get a response like the following, then the server is up and running:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html><head>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />

<script type="text/javascript">
location.href = 'login.jsp?jsessionid=27400cbfbaa762671551d314eece54d7';
</script>
</head>

If you are not automatically redirected to the login page, then
Javascript is currently disabled or your browser does not support Javascript.
For this application to work, Javascript is essential.
Please enable Javascript now, or use another web browser that supports it.

</body></html>

If the curl test succeeds, then there might be something wrong with the firewall. Otherwise, do you have other services using port 9123?

Regards,
Nicola

Hi, if you are not able to connect to the service on port 9123, I suspect that the db server is not enabled or not properly configured.
Maybe you can have a look at Kura.log and Kura-console.log to get an idea of what is going on.

From the log posted, you see that a message is received by the logger. But actually there is no message referring to the database.
By the way, if you want to have a look at the content of the messages logged, please update the logger configuration, setting it to "verbose".

Best regards,
Matteo

The log seems not downloadable for me.

To access directly the data, apart from the web interface, you should consider the way the database is configured. Maybe have a look here: http://eclipse.github.io/kura/builtin/h2-database.html#persistence-modes

I'm sorry, it is still not clear to me what you are trying to achieve here: if you are working with wires you can use the "H2 DB Store" that is actually responsible to get wire messages and store them in the referenced H2 DB instance.

If you want to create other data to push to the database, you can also use the Script filter component: http://eclipse.github.io/kura/wires/1-kura-wires-script-filter.html

Hi,
if the channel supports writes, you should be able to change the values.
It depends on the sensors/actuators you have attached to the OPCUA server, if you are allowed to change those values.

Hi,

I did't attached any sensors/actuators i just use OPC-UA server simulator with opc-ua driver and create asset or checking the data on server of h2db but the data which i am getting is fluctuating sometime temperature comes as 25.666 or sometime it's come as 27 so i want to know how to access the data so that i can understand why it's happening,

For what I remember the simulator exposes data based on a certain rule. The fact that you see different values may be related to the sampling rate you are using.

It's not clear to me what you mean when you say that you want to access the data. My question is: where? in the simulator or in kura after you fetched this data?

I think that the simulator logic is fixed and hardcoded.
If you want to change it, you'll need to update the simulator's source code and redeploy it.

Hello,
the OPC DA bundle is not an official Eclipse Kura bundle. I believe you should try to contact the author to get help on this.
