Hi,

Thank you for the useful research.
The approach of using binary data format has several advantages:
– It is optimized and can be improved to provide very fast access.
– Doesn’t depend in 3rd party software => easy to install and backup

So, I have no plans of moving to RDBMS.

Or improve performance/method access to .DAT files…

I agree. This work is permanent. For example, the new web app has modern cache to allow multiple users access data faster.

30-days 10-chnnels chart contains 24*60*30*10 = 432000 points. It is not a few.
May be the bottle neck is drawing these points.

Could you generate similar Excel report and compare the duration?
It would be interesting to compare with other JavaScript charts such as http://www.highcharts.com in conjunction with MySQL or PostgreSQL (like here).

If you could continue the research, it would be wonderfull 🙂

Hi,

The planned release of the new web app is the end of summer 2016. I hope beta version will apear earlier. It is not official date because there is no contract for this work.

Thank you for the links, I will take them into account. The difficult thing is integrating existing components into the project’s environment. Sometimes it’s more effective to take the idea and some code, and create an own control.

If you are a developer, let’s join to Rapid SCADA development. The new web app has module structure, you can create plugins and publish them to rapidscada.org to allow people using them. It’s very exciting 🙂

[Mikhail]

To be honest, thanks to the project community. Many users – many issues – many ready solutions. It is the power of open source 🙂

[Mikhail]

Thanks! Do need programming to integrate it with database or it is out of the box?

[Mikhail]

How do you make charts for the data from DBMS?

[Mikhail]

Hi,
The module executes SQL every time when data are received from Communicator. But Communicator doesn’t send data if they are not changed. You can set the parameter Sending all device data period in Communicator to solve the issue.

[Mikhail]

Try the following:
0. Make a backup of C:\SCADA\ScadaWeb\Web.config
1. Open C:\SCADA\ScadaWeb\Web.config
2. Find the line
3. Delete httpsGetEnabled=”true”
The line should be

Open http://localhost/scada/scheme/ScadaSchemeSvc.svc again.

[Mikhail]

Instead of sponsor it could be a guy, who develops a BACnet driver for Rapid SCADA ))

[Mikhail]

What is your Windows version?
Please open http://localhost/scada/scheme/ScadaSchemeSvc.svc and post a screenshot.

[Mikhail]

Hi,

There is a topic about BACnet: http://forum.rapidscada.org/?topic=bacnet
In short, it would be great to implement BACnet, but for the current moment there are several the most priority tasks. BACnet can be included in the nearest plan if we find a sponsor for this feature.

[Mikhail]

OK 🙂

[Mikhail]

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

[Mikhail]

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.

[Mikhail]

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.
