Hi,
Probably, you should install or reinstall OPC Core Components.

The Beat() function just changes a channel value every 5 seconds to be a trigger for sending commands. What value you need to insert?

Hi,
You should associate HTML file extension with a modern browser.
Other option:
After starting the editor, open a browser and copy this link:
file:///C:/SCADA/ScadaSchemeEditor/Web/plugins/SchemeEditor/editor.html

[Mikhail]

Also is it possible to display a timestamp of the when the device was connected last?

You can also implement it using formulas.

I’d like to say that the connection is not stable, it is not normal, you should find the cause and make the connection better.

[Mikhail]

Instead of defaulting to zero.

You need a formula of input channel. Try this: Stat > 0 ? Cnl : Val()

Hi,
If you need HTTPS, you have to do special settings on IIS. See this

[Mikhail]

Hi,
What Windows version do you use?

You should open incoming connections on TCP port 80.
To check, just open http://yourIP/ from another PC. You should see IIS welcome page.

[Mikhail]

OK, be free to ask 🙂

[Mikhail]

Hi,

Polling is slow, because the device doesn’t respond for “State” requests. Deactivate such requests in the template editor (keep “Temperature” active only) and compare the speed.

Scheme Editor were changed. There is the old version in the video. Please create a new topic if it doesn’t work. editor.html must be open in a web browser not Word.

[Mikhail]

Hi,
Thank you.
The expected behavior in this case: values and statuses of tags are zero when connection is broken. Does it work as expected or not?

“Unable to request because connection is not established” – probably, the device disconnects from the PC. If this is a usual LAN, you should check communication with Modbus Simulator installed on another PC. If it works normal, the problem is in the device.

[Mikhail]

Hi Marko,
Nobody has purchased the development of this module yet. You can be the first 🙂

[Mikhail]

Add to the Formulas table:

double Beat()
{
  return (DateTime.Now.Seconds % 10) < 5 ? 0 : 1;
}

Then use in the channel: Beat()

For example, when we got similar error with Inneasoft BACnet OPC server, I wrote to the developer and he implemented all the required methods according to the OPC specification to make the OPC server works with the libraries that are used by Rapid SCADA.
We can try the same approach.
Rapid SCADA uses the official libraries by OPC Foundation. Unfortunately, they are capricious. I hope the future is cross-platform OPC UA.

[Mikhail]

Hi,
Please provide logs of communication line when the device is offline.
Also provide a screenshot of the values when the device is offline.

[Mikhail]

Hi,

Does it work from another PC in the same network?
Please press F12 in a browser and provide logs (or screenshots) from the Console and Network tabs.
