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).

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.

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.

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?

[Mikhail]

Hi,

I see your point. It’s important.
Currently, you can use scheme templates if the schemes are identical except channel numbers.

Could you make a screenshot and describe what part of the scheme you need to update? It would help to understand your particular case.

Hi,

Just open the Units table and add as many units as needed.
Units available by default will be extended in the v6, see the link. Meter included.

[Mikhail]

Other possible method is when each remote site uses different TCP port. But in this case any unknown device can send data to your system. And the number of TCP ports is limited.

[Mikhail]

Hi,

Not related to the particular SCADA software, when DTU is connected to the main server, what method would you like to use by the server to recognize the remote site?

In such situation, a remove device usually sends “hello” packet that contains the device name. This feature is supported by some 3G routers.
