I did not know how to install only ScadaWeb

You can choose checkboxes in the installer.
Anyway you have installed it 🙂

Dear Tarak,
If you mean showing sliders, you should create a set of images using your favourite image editor in PNG or JPG format. Each image will contain their own level. Then open SCADA-Scheme Editor and use Dynamic picture component. Configure Conditions property of the component to show an image according to input channel value. Don’t forget to specify Input channel property.

Thanks!
I will try to “Install lantronix virtual serial COM port software on your computer and connect to my device over the Internet”.

If I can’t connect then try to “direct access to the computer running communicator (i.e.: teamviewer) to do ANY tests”

Let’s continue on the next week, OK?

[Mikhail]

Hm, scrollbar used to be, but disappeared )

[Mikhail]

Of course. I do the best to make this moment closer.

[Mikhail]

I need somehow to reproduce the problem on my PC. Do you have any idea how to do it?

[Mikhail]

SCADA-Web is installed incorrectly. Try reinstall SCADA-Web. If the installer shows error, post it here.

[Mikhail]

My results for the current version of SCADA-Web after 1 or 2 hours of work:
FF – changed: 1.2GB => 400 MB => 600MB => 20MB – freeze
IE – increased to 600MB – freeze
Edge – changed: 15MB => 3MB, but background Edge process 2GB
Chrome – changed: 25MB => 15MB, but background Chrome process eats RAM, sometimes page can’t be displayed and memory is cleared – not fair

I will try with old jQuery. The jQuery ticket that you found is very interesting.

New scheme engine after the night:
FF – 130MB
Chrome – 17MB + 21MB background Chrome process

[Mikhail]

It’s already done, that’s what is weird!

Did you mean that Delay after request cycle parameter solves the problem?

[Mikhail]

Is it a screenshot of your OPC server?

[Mikhail]

Periodically I do similar tests. I should repeat them.
That’s funny, but a few years ago SCADA-Web run stable on IE for days. And Chrome supported Silverlight 🙂
I think that the cause of memory leak is reloading frames within web page. This approach is outdated and will be changed to REST API.

[Mikhail]

Shouldn’t apply delay in case of any error too?

I think that you did is enough.

Where can I get it?

It will be included in the next version. In case we found the workaround I think you shouldn’t update Communicator. But if you wish, I can send it by email.

[Mikhail]

As I realized the most fast communication if UDP is used directly for a serial converter without virtual port and C:\SCADA is ignored by anti-virus system.

[Mikhail]

Without a delay Communicator tries to write in the loop. So CPU become loaded.
I will add the fix in the core of Communicator.

Does the connection repair automatically or you need to restart Communicator?
