I wonder if you are already using SQL Server lite for objects/channels… why not for data too?

Pros of file storage:
– Performance
– Works great on systems with low resources, e.g. Raspberry Pi
– Easy to refactor depending on the project needs
– No dependencies on 3rd party

Cons:
– Unable to write SQL requests
– Unable to retrieve data using standard tools

The ideal way is to implement the ability to use different data storage engines.

Hi,

You need to develop or purchase a module for SCADA-Server. Use this one as an example.

[Mikhail]

Hello,

This limit is defined in DiagCnls.aspx. You can change it, I think it should work.
You right, the possible problems are layout and performance.

How many channels do you compare in the work proccess?

[Mikhail]

Hi,

Please, create a new topic, this one is not appropriate. Furthermore, provide more details about your task.

[Mikhail]

You should use srezAdapter.Update(srezTable) method after modify data in srezTable.

Changing data:
https://github.com/RapidScada/scada/blob/master/ScadaServer/ScadaServerCtrl/FrmSrezTableEdit.cs#L331

Saving: https://github.com/RapidScada/scada/blob/master/ScadaServer/ScadaServerCtrl/FrmSrezTableEdit.cs#L103

“Srez” means a snapshot ))

For the old web app you should enter views into the Interface table if you need custom user roles. For the new web app all the views must be in the Interface table.

[Mikhail]

Are you talking about the new web app or about the current version? My note was about the new.

[Mikhail]

The server code of the all Rapid SCADA applications are highly stable, and the apps work for months and more without restarting.

The issue may occur with a browser on a client side if the browser doesn’t be reopened for a few hours. The new web application which works great is under active development. You can install the prototype (see this link)

[Mikhail]

For now the prototype supports schemes, table views and events.
Charts, commands and reports are under construction.

Use fresh version of Chrome (recommended), Firefox or Edge. It also works on iOS and Android. Don’t forget to update your browser.

In case of issues, please, create new topics.

[Mikhail]

I have published the prototype http://rapidscada.org/download/scada_web_beta.zip
Look for installation instructions in manual_setup_en.pdf of the main distributive package.
The files of the prototype have to be located in C:\SCADA\ScadaWebBeta\
Define views using SCADA-Administrator as shown on the screenshot

Then enter view IDs in the file C:\SCADA\ScadaWebBeta\ViewSettings.xml

[Mikhail]

Function and variable names are case sensitive. Check it.

[Mikhail]

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.

[Mikhail]

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.
