Hello,

You should open the DLL file properties and unblock the file.

Hi,

Please provide screenshots of the module settings and logs which can be found in C:\SCADA\ScadaServer\Log\ModDbExport_*.log

Hi,
This subforum is related to OPC issues, not SQL server. Please create a new topic here providing screenshots and log.

Hi,

I don’t want to put it onto my live system

In this case you should develop (or order development) a driver for Rapid SCADA to poll devices using the custom communication protocol.

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.

[Mikhail]

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.

[Mikhail]

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.

[Mikhail]

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.
