Hi Marek,

That’s right. You can check here.
But the best way to check is watching communication log in Communicator.

Hi,
Function 0x10 already supported. The driver KpModbus.dll uses 0x10 function if you tick Multiple checkbox for a command.

Hi! To be honest, I have no info about RPi emulation. If you run Rapid SCADA on the emulator, please let me know.

[Mikhail]

Hi,
Just use Dynamic Text element in your scheme. Set its border, back and fore color, and specify appropriate Action and Input/Output channel properties. It will work as button.

Copy the full request URL of GetHourCnlData into browser address bar and make a screenshot of the result.

[Mikhail]

Hi,
Yes, do the following:
1. Open Chrome and press F12
2. Go to Network tab
3. Find the requests sent to a web server.
4. What dates are in the requests? Provide screenshots please.

I can connect to you remotely and help on commercial basis if you would like. It may be mach faster than forum support.

You forget a log file. It’s name is lineXXX.log

[Mikhail]

Please provide communication line log (C:\SCADA\ScadaComm\Log) and the result of the following SQL request:

select distinct datetime from cnldata order by datetime desc

[Mikhail]

In general, yes. You should find out how to run browser in kiosk mode on Raspberry startup.

Hi,
I recommend Raspberry Pi 3 Model B. Usually, I connect to RPi remotely using Putty and WinSCP to configure it, and don’t need a screen for RPi.

Hello,

I agree, it is strange that time stamps are so close to each other. How many polling cycles are performed by Communicator per second? Do they stay close in long time interval?

We can develop SQL scripts according to your custom requirements on a commercial basis.

[Mikhail]

You can decrease polling speed of Communicator by increasing delay after requests.
Or may be change SQL for export current data to fit your needs.

Hello,

SQL script for export archive data is executed very rare, in special cases when a driver of Communicator implements this feature.

SQL script for current data is executed for each value of input channel (tag) that is sent from Communicator to Server.

[Mikhail]

To see the information, open up to date mobile browser and type http://your-address/scada
Find out in the Internet how to create shortcuts.

[Mikhail]

I mean that the web application is properly tested on iOS and Android. It is possible to create a shortcuts on mobile desktop to run the app by one click (tap). Even if web server works on Windows, the web interface is accessible via LAN or Internet using different devices.
