Hello,

Try the same but close a web browser. The web application may cause browser memory leak, unfortunately. The new web app works well, it will be released soon. If needed, I can send you the prototype of the new web app.

[Mikhail]

Definitely.
If Communicator interacts with Server, communication settings of Communicator app are overridden by the configuration database.

P.S. You can also use Russian forum if it’s more suitable.

Hi,
A simple application is needed to update data because the archive is not SQL database.

[Mikhail]

Can you see input channel numbers in the Channel column of Device Data page in Communicator? If not, it means that input channels are not bound to the device tags, so data are not passed from Communicator to Server.

Go to SchemeViewAction class defenition in ScadaScheme silverlight project (by pressing F12). It’s in the file Reference.cs that is “generated by a tool.” You have to right click ScadaSchemeSvc in solution explorer and update service reference. You need the value “OpenLink” be added to the service reference class defenition.

Hi,

It’s difficult to answer without debugging. I assume that web service autogenerated code must be updated using VS.

The core of schemes will be significantly redesigned this year. It may cause double work for you. The prototype of the new web app is here http://demo.rapidscada.net
Login and password are admin/12345

It is planned to support 3rd party controls to allow developers creating their own components, but API hasn’t been developed yet.

Hi,
See http://forum.rapidscada.org/?topic=writing-additional-data-for-example-infotext-to-historical-db/#post-904

[Mikhail]

OK 🙂

Hi,
To publish an image you need external hosting, e.g. postimage.org
Could you provide more information about your questions?

[Mikhail]

Use postimage.org and post links.

[Mikhail]

Post screenshots for such questions, please.

[Mikhail]

Probably the Simulator doesn’t support more than 1 connection.
You can set another TCP port followed by IP address: 127.0.0.1:503

The formula is applied in SCADA-Server. That’s why you can’t see a result in Communicator. You have to configure displaying data by SCADA-Web app and you will be able to see calculation results.

[Mikhail]

Do the both communications the old and the new work in parallel?
Post a piece of communication log, please.

[Mikhail]

You should use a formula of the appropriate input channel in SCADA-Administrator application.

The formula below will be useful. Add it in the Formulas table and use in the formula of the input channel.

public double GetByte(double val, int n)
{
    UInt64 uintVal = (UInt64)val;
    return (uintVal >> (n*8)) & 0xFF;
}

The formula of the input channel is like

(((256*GetByte(Cnl,3))+GetByte(Cnl,2))+(GetByte(Cnl,1)/256)+(GetByte(Cnl,0)/(256*256)))/10

I haven’t tested it.
