You have to use Caclculated channel type for channels 2&3 and define formulas for them.

Is an alarm value for Channel 1 is generated by a device? In this case you can calculate values of other channels using formulas which depends on Channel 1 as you wrote Val(n). May be I didn’t catch your question.

It’s weird.

I usually do the following:
1. Copy *.css to C:\SCADA\ScadaWeb\css overwriting the existing file.
2. Open the web application in a browser and press Ctrl + F5

If you think that a file is not updated, delete it first, press Ctrl+F5 to make sure that styles disappear, then copy the new file and press Ctrl+F5 again.

Hi Fahrur,

There is no such protocol in the nearest plan. There are 2 ways:
1. Using OPC server, for example, http://www.matrikonopc.com/opc-drivers/opc-dlms/base-driver-details.aspx
Pros:
– Faster to start.
Cons:
– You should pay for each license of the OPC server.

2. Purchase development of a native driver for Rapid SCADA.
Pros:
– More effective and stable in work.
– You should pay once.
Cons:
– Take more time to develop.

Hi,

The manual contains the hardcoded functions. Whereas, GetBit is defined in the configuration database in Formulas table.

You definitely right – the documentation should be updated and improved. In the plans there is changing its format to HTML to make updating easier. Unfortunately, work takes more time than generating ideas )

Thanks a lot for your vision.

The easiest way tor debug your formulas is creating console application using Microsoft Visual Studio Community Edition.

Hi,

To create a new function open SCADA-Administrator -> Formulas table. It already contains a few examples.

If you need a formula to calculate input channel value, it should be as the following:

double MuFunc()
{
  return 1; // for example
}

Then enter the formula in the Input channels table: MyFunc(); 1
Where 1 is status of the input channel.

Anyway the channel value is double. If you need string representation, use Unit table (find the example in the default configuration database).

Also read about using formulas at Part 3. Software Configuration in http://rapidscada.org/product/documentation/

Thank you for the info.
The issue is entered in the tracker in order to be resolved in the future.

[Mikhail]

Solved. Will be published in the next version.

[Mikhail]

Radix, could you write the required formula using C++, C# or math? In this case, I can tell how to apply it to Rapid SCADA.

[Mikhail]

I you don’t find the answer with Chrome, I’ll help you, OK?

[Mikhail]

Hi,

You can easily the find the answer with help of Chrome. Press F12 and find the element by a mouse. Chrome displays the css file and line number.

I recommend not to waste much time, because the web app will be totally redesigned.

[Mikhail]

First of all, let’s make sure about the reason. Please write about the result after changing localization.

[Mikhail]

Hi,
The manual is inside the installation package. The file name is Doc\dbexport_en.pdf
Try using database model and scripts from the manual.

[Mikhail]

I think it will be good idea to implement connection timeout. It will be done in a one of the future version of Rapid SCADA. Also this work can be accelerated on commercial basis.
