execute some external app from the web interface

[fischerp]

Hello,
I would like to call the function contained in Utility Pack 6.0 for creating a CSV file (CsvExport.exe) from the UI. Is this possible? Possibly even in such a way that the file name, time period and channel number are transferred directly when the function is called?

script fo run app

and modul_for_run_app

Thank you for your answer, unfortunately I can’t do much with it because I don’t speak Russian.
Obviously I need to embed the code that Mikhail shows in the linked post somewhere. Is that correct?
Where?
And how do I then access the function?

There are always online translators, which we use successfully, I also don’t know English well 🙂

You can add Scripts to the table

public double StartProcess()
{
  Process.Start(@"C:\SCADA\1.bat");
  Console.WriteLine(DateTime.UtcNow.ToString());
  return 1.0;
}

and call this function in the output formula of the channel.
Starting an external process is an unsafe action.

translation of the readme for the module

Extension for launching external applications from RapidScada v.6.2.1.1

ModAbcLogicConfig.xml – a file for configuring the extension.
– AppObject – Settings for launching the application (each application has its own settings).
– – Input Channel – The channel number in Scada. The extension reads the value in the channel (it should be 0 or 1), 0 – does nothing, 1 -launches the application.

Hello,
The general algorithm is as follows:
1. Send a command via the web interface.
2. In a channel, use an output formula that executes a script.
3. As shown above, the channel’s output formula should run a command like Process.Start(@"C:\SCADA\1.bat");

Ask for more details if needed.

Note that executing external scripts is not secure. They can hang, or can be modified by an intruder. It’s better to interact with other services via API or industrial protocols.
