For example, -; Alarm; Armed; Disarmed; Fired; Normal
– equals 0,
Alarm equals 1,
Armed equals 2,
etc.

Hi,

See this guide page 6. I hope we will create new documentation system soon.
You can create formulas in Formulas table for reusing, and you can define any number of strings, not only Opened and Closed.

[Mikhail]

Yes.
1. Create a new input channel number 4 (number must be greater than existings) of type Calculated discrete.
2. Create a record in Units table for “Opened and Closed”. See No-Yes as an example.
3. Set Formula field for the new input channel. Something like

Val(1)>0 && Val(2)<=0 && Val(3)<=0 ? 1 : 0

4. Set Unit field for the new input channel to your unit that you just created.
5. Set Format field to Text.

Please contact me by the email. I can send you my Skype ID.

You should develop or purchase a driver that implements required functionality and “knows” the model of your database. Driver is a DLL written in C#. See this article http://rapidscada.org/device-drivers-development/

Hi,

I think the cause is Windows Communication Foundation (WCF) problem. Check WCF checkboxes as shown in “Rapid SCADA. Before installation. Switch Windows XX features on” video of the playlist.

[Mikhail]

I think, we will implement the required functionality sooner or later. It is not included in the plan for now, but in case of some commercial interest, we can arrange it.

The technical limits:
– ASCII encoding
– max. length is 8 characters
Is it OK for you?

[Mikhail]

In case of errors, please create a separate topic.

[Mikhail]

Also you must update KpSnmp.dll

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

[Mikhail]

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.

[Mikhail]

Thank you Young for so kind words 🙂
Merry Christmas!

[Mikhail]

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?
