Hi,

1. Add your scripts into the Scripts (v6) or Formulas (v5) table.
2. Write a DLL in C# using the examples from GitHub.
3. The MQTT driver support JavaScript.

Please specify your question.

In Chinese please write in this subforum. Or use English.

I did the following test:
1. Use the default settings of the OPC UA Server data source. The Automatically accept certificates checkbox in set.
2. Install and run Prosys OPC UA Browser.
3. In Prosys OPC UA Browser
– Security settings: Sign, Basic256Sha256
– User auth: username and password (opc / scada)
4. When connect, the client asks to accept the certicicate.
5. Connected successfully.

Note: the same machine for client and server.
Could you repeat this test?

If you need to check all existing events associated with a channel, it’s possible, but may slow down the performance.

[Mikhail]

Hi,

You can load an event by ID and check the Ack field.
Do you use Rapid SCADA 5 or 6?

[Mikhail]

I can check this issue the next week.

Hi,
Copy the plugin configuration files from the installation ZIP to the project.
And as written above activate Chart Pro in the project using the Administrator app.

Hi,

There is no recent changes in custom pages.
“Blazor is a feature of ASP.NET for building interactive web UIs using C# instead of JavaScript” So it’s a client feature.
We don’t plan to use it because we afraid it could be “Silverlight II”.

[Mikhail]

Do you get an error in the client if you try to connect using Basic256Sha256 if the OPC server uses the default settings? What error?

[Mikhail]

If you need more clarification how that file is created and used by the driver, ask.

[Mikhail]

As for me, no.

[Mikhail]

If DrvDsOpcUaServer.xml does not exist, the driver creates a default configuration file. You can put it in the project and change if needed. I recommend to use the default configuration if it fit your needs, because there are a lot of settings which are not obvious. The file in the screenshot was created by the OPC Foundation developers (and included in the driver), and I haven’t seen any documentation related to it.

[Mikhail]

every signal have default limits (0 to 100) but values are higher than limits

In this case, you get Bad quality status?

[Mikhail]

If you need to use values with bad status as good values, I can provide the source code of the OPC DA driver, so you can change it as needed.

[Mikhail]

In SCADA I created 2 fields showing column 1 and column 2

Good workaround. Thank you for the idea.
