Thank you for the info.

Hello,
If you use *.dat archives, they record data with a fixed period. So the number of records is constant.
If PostgreSQL archives are used, you can count the number of records by SQL request.

Hello,

> how many values were read for each channel
Please clarify what does it mean “how many values were read”?

[Mikhail]

If another software opens the port, it cannot be opened by Rapid SCADA.

[Mikhail]

Hi,
The software should try to open the port when it is available. What is in the log?

[Mikhail]

In Rapid SCADA it’s a bit different:
When you click a button, a popup dialog is shown, where you can choose an option.
To do that, you need to configure a channel of the output type. Then specify the channel number in the button properties.

Please don’t mess up many topics in one. Create new topic for other questions.
Archive kind should be set to historical.

[Mikhail]

Manually add a row in the Archives table.
If you provide screenshots, I can check.

[Mikhail]

Hi,
That’s interesting!

[Mikhail]

You can write data on change. It is supported by PostgreSQL archives.

> Just for a selected channel, not all of them.
It’s needed to create a new archive in the configuration database and in the Server settings. The created archive should not be marked as default. Then you can set an archive mask of the channel to write that channel to the certain archive.
Ask for the details if needed.

[Mikhail]

In the Scripts table add

public double StartProcess()
{
  Process.Start(@"/opt/scada/myscript.ssh");
  return 1.0;
}

and create myscript.ssh containing the necessary commands.
Then use that function in the output formula.

Hi,

The time seems to be converted from UTC to local time, so in order to become UTC in the view, I would have to convert it additionally.

That’s right. Probably, we need to add an additional option to control displaying.

[Mikhail]

To shut down a Linux machine it’s better to connect by SSH and execute a shell command.

[Mikhail]

Hi,
You can create a channel with an output formula that executes an external script to shutdown the machine.
But it’s not a good practice.
