Hi,

1. Create input channels for string tags.
2. Create such formula in Formulas table (not tested):

int GetStrNum()
{
  byte[] buf = BitConverter.GetBytes(Cnl);
  string s = Encoding.Default.GetString(buf);
  if (s == "MyVal1") // your string values
    return 1;
  else if (s == "MyVal2")
    return 2;
  else
    return 0;
}

3. Create your own record into Unit table. Use the units 36 and 37 as examples.

4. Enter GetStrNum() in formula field of input channels, change channel type to Discrete and change format to Text.

Please write about the result.

It usually happens if WCF for .NET Framework 4+ is not installed. See this video

I mean, you should know all the possible values of the strings.

[Mikhail]

Hi,
Currently, only predefined strings from enumerations are supported. You can’t display custom string as values of input channels of Rapid SCADA. If your strings can be specified in enumeration, I can provide the details how to configure Rapid SCADA. Otherwise, if you are able to receive the strings and display them on your own web page, you can embed this page into the web application of Rapid SCADA.

Thank you Young for so kind words 🙂
Merry Christmas!

Dear Young,

Thank you for the research.
I have an idea:
1. Copy ScadaCommMono.exe from Rapid SCADA for Linux installation package to C:\SCADA\ScadaComm\
2. Run it instead of the service.

This is the same Communicator but works as a console app.
Does it work with your OPC server?

[Mikhail]

I think the cause that the service and your app work by different users. Service works as system. Your app works as other user. Try changing the user of the service. See the end of the article http://rapidscada.org/connecting-devices-using-opc-standard/
Please write about the result.
Note. What do you think is OPC UA is actual for you?

[Mikhail]

Call number is a device additional address in terms of Modbus.
If you need advice about configuring Communicator, provide more information about the issue.

Hi,

There is no native Rapid SCADA driver supports Profinet.
You can connect to Profinet device using
1. OPC server
2. By creating (by your own or purchase) a Profinet driver for Rapid SCADA.

As far as I know, Siemens S7 supports Modbus protocol. You can use Modbus devices with Rapid SCADA out-of-the-box.

[Mikhail]

Be careful, if the statement is true on every program cycle, you will run a lot of processes.

[Mikhail]

Hi,

You can try using in a formula the following code:

System.Diagnostics.Process.Start("C:\you_file.bat");

Please tell about the result.

[Mikhail]

There is a step by step guide

[Mikhail]

What OS do you use on your RPi?

[Mikhail]

Please read this manual http://rapidscada.org/connecting-devices-using-opc-standard/
In case of additional questions, ask on this forum.

4. Install Rapid SCADA on the embedded server if it is possible. And optionally, install the web app of Rapid SCADA on the remote server.
