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.

Hi,

Mudbus TCP usually uses 502 port. Try setting up the communication channel. Use TCP client channel type.

[Mikhail]

If you’d like to switch off SCADA-Server, you should uncheck Use SCADA-Server option in Communicator.

[Mikhail]

You are requesting the same when the communication is OK and when it’s broken.
It means that something wrong with a simulator application. May be some settings of the simulator were changed, e.g. device address.

[Mikhail]

active and bound option again in request sequence, while it is already taken in line parameter.

Unchecking Active disables a whole communication line or a device.
If Bound is true the data from a communication line or from a device are sent to the SCADA-Server. Unchecking Bound of a communication line is the same as unchecking this parameter of each device.

significance of timeout and delay

Timeout is the time while you are waiting for the responce from your device.
Delay is the delay after receiving data before the next request.
They should be set experimentally to provide stable communication.

delay after request cycle

Additional delay after requesting all the devices of the communication line.
