If you create a module for SCADA-Server, you can use PassCommand() method within the module.
If you create a driver for Communicator, you can use CommLineSvc.PassCmd() method to send command to a device that is bound to the same communication line.

Hello,
Please provide more information how data are transferred from PostgreSQL to Rapid SCADA?

[Mikhail]

It’s true.
Kurlekar, if you need to speed up development of the required feature, you can be a sponsor of this feature.

Hello,
If you choose the fore color “Status” for the dynamic text, its behavior becomes similar to table view.

[Mikhail]

It seems fthe following formula doent work properly

Hello,
Please clarify what do you mean?

[Mikhail]

Sometime the received data are incorrect. You can check it by http://modbus.rapidscada.net/ or any other Modbus parser. I recommend to try increasing a delay after request in Communicator (Request Sequence tab). Probably the polling speed is too fast for the particular device and network.

Hi,
First of all, create a new topic and provide screenshots and logs.

[Mikhail]

Also check that Communicator is connected to SCADA-Server.

[Mikhail]

Data are not lost. The values equal 0 from 12am to 12pm.
The next time when the issue repeats, you need to check communication line log in Communicator and find out the cause of the error.

Hi,

It would be great if you tell about the progress of your work in this forum topic.

[Mikhail]

Please provide the necessary screenshots.

You need to choose the correct parameters in your Modbus template in the Communicator app. Set correct type of register and byte order. Try the empty and 2301 byte order.

Hello,

I work with WinForms and WPF. Both of them are stable and a good choice. WinForms is more simple for a developer. WPF allows to create really beautiful rich applications with cool GUI themes which you can download. But WPF requires more LoE in compare with WinForms.

These platforms work fast and performance depends on developer skills.
Also you should think about using OpenGL or Direct Drawing for the GUI.

I haven’t developed using UWP. I think it is a good choice if you want your app to be cross platform.

[Mikhail]

You can try changing the port in C:\SCADA\ScadaSchemeEditor\ScadaSchemeEditor.exe.config

Hi,
“System.ServiceModel.AddressAlreadyInUseException” means that TCP port 10001 already used by another application. Try to find this application and close it. Use TCP View utility to check opened ports.
