Hi,

1) I suggest at least Windows 10 or Linux.
2) You need static IP address.
3) http://SERVER_IP/scada
If you register your domain name, you could use address like http://rapidscada.net/scada/

Hi Rich,

RS-232 is just a communication interface. The most important is how data is encoded when transmitted.

Do you successfully write values to a text file?
Does the above formula to retrieve data from text file work?

[Mikhail]

The new Rapid SCADA 5.8.4 contains fully redesigned Export to Database module. I recommend to update.

Hi,
Module screenshots and logs appreciated.

how does the module knows wich channels to export?

The current version of the module exports all channels. In the next version, a user can specify the channels.

Hello,

This error probably means that the driver version is incompatible with Rapid SCADA version.
Please check Communicator and Administrator versions.
Full error message would be useful, it can be copied from C:\SCADA\ScadaAdmin\Log\ScadaAdmin.err

[Mikhail]

The formula would be something like:

double ReadNum()
{
  try
  {
    string s = System.IO.File.ReadAllText(@"C:\mydata.txt");
    double val;
    return double.TryParse(s, out val) ? val : -1;
  }
  catch
  {
    return -2;
  }
}

Hi,

and writes it into a text file like ‘mydata.txt’, its simple the text file just shows a single number like 22.3

Could I not just write a formula to read this ‘mydata.txt’ file into RapidScada and then return this number from the file

This is not optimal, however, it’s possible if the file contains only 1 number.

Create a formula and use it for an input channel of the Calculated real type.

Hi,
1. No, the module is free.
2. Specify the query in the module configuration.

If you provide screenshots of the module settings, I can check.

Hi,

Please check the driver development article and the existing driver as an example (link 1, link 2).

[Mikhail]

Hi,

Despite the successful installation, only “administrator” and “Webstation” items appears in the start menu.

It’s correct. You can control the Server and Communicator services from the Administrator app.

The Agent service start automatically when the PC is restarted.

Hi,

Rapid SCADA supports COM ports. But you also need a driver (dll) for Communicator that implements recognizing the data in a particular format. It’s possible to develop such driver.

[Mikhail]

Hi,

There should be PlgChartPro.xml file in your project. The default file contains in the installation package of the plugin. Copy it into the project if it doesn’t exist.
This file contains required parameters.

[Mikhail]

Hi,
You did everything right.
A new user for Rapid Gate should be of the Application role.

[Mikhail]

Hi,
As I remember, yes.

[Mikhail]

That is the solution. The 4G DTU contains the config.

Nice 🙂
What solution method have you chosen?
