I’m not sure, but may be MQTT is not very fast communication protocol. To compare, try the Modbus example and measure how many messages you can receive per second.

Hi,

Try decreasing the delay parameter for the device in Communicator.
It’s here http://rapidscada.net/doc/content/latest/en/software-configuration/communication-with-devices-files/comm_line_req_en.png
This should increase polling rate.

Are there changes in performance if you install Rapid SCADA and MySQL to a physical machine?

[Mikhail]

Hello,
If you install another OPC server, can you see them in the list?
BrowseOPC utility can be useful.
Its source code.

OK )

Hi,

You should use ScadaAdmin user to connect. Check that ScadaAdmin exists in the Users table.

[Mikhail]

In RPi find the file /opt/scada/ScadaAgent/Config/ScadaAgentConfig.xml
The secret key in the file must be the same as the secret key in the configuration profile.

In Administrator you should export the User table to user.dat and copy to /opt/scada/BaseDAT

To get more info about error, see /opt/scada/ScadaAgent/Log/ScadaAgent.log

[Mikhail]

In this case, it’s better to set View ID property of the link than URL.

Hi,
I think, you should use real physical machine, because performance of a virtual machine is unpredictable.

What database model do you use?

Please create a different topic to discuss MQTT. One subject is a one topic.

In Rapid SCADA v5.8 it’s easy to transfer the configuration.
You should create a new deployment profile in Administrator. Set RPi’s IP address and other profile parameter. Then upload the configuration to RPi. Don’t forget that in Linux you need different directories for SCADA-Server. Before switching from Windows to Linux, change the directories in Server configuration (using Administrator).

Hi,
Agree this is a useful feature. We keep it in mind.
Now it works only for the Button component.

[Mikhail]

Then vice versa, delete /opt/scada/ScadaServer/Mod/Mono.Security.dll and restart the Server daemon.

[Mikhail]

Try the following:
1. Download Mono.Security.dll.zip.
2. Put the DLL into /opt/scada/ScadaServer/Mod
3. Restart the Server daemon

[Mikhail]

To get quick results with export data to PostgreSQL, it would be useful to involve our team in the project. We can help to fix the export process, and upgrade the export module if necessary depending on the requirements.

[Mikhail]

show realtime data on a chart contionously, without refreshing the webpage?

We work on it now. Coming soon ))
You can contact us by email to get early version for testing.

We are trying to build up a system based on Rapid SCADA to design a mass ventilator system for treatment of group illnesses, specifically to COVID19.

Wow
