    Could you tell more about the system that you are going to implement? The understanding of the aim helps me to suggest the best solution.

    Porting of SCADA-Web is under construction. You can wait for it or fork the project on GitHub and make the necessary changes.

    The web application SCADA-Web can be deployed on any free ASP.NET hosting in the Internet or in your LAN. SCADA-Web connects to Raspi and retrieves the data.

    The one of known issues – Raspi doesn’t contain real time clock. That’s why after reboot a system, SCADA may write data with incorrect timestamp. This issue can be solved by writing special script that starts SCADA after a clock sync.

    Dear Tom,

    I think Rapid SCADA perfectly fits your purposes. Of course you can use it.
    Rapid SCADA has low hardware requirements, full features and stable.
    Talking about possible problems, we have no enough statistics about working on Raspberry Pi because the appropriate version of the software was recently created.

    The best way is to start using Rapid SCADA on Raspberry and interact with me in this forum to discuss and solve issues.

    Thanks!

    Most likely you need to choose IIS application pool that uses .NET 4.

    In the case of using Modbus RTU you need to create virtual serial port. The most of converters including Moxa supports creating virtual serial ports.
    Probably, Moxa converts Modbus RTU to Modbus TCP and the data exchange is correct as you show in the first sample, so you don’t need RTU.

    Hello,
    1 and 2 seconds have to work. Try restarting IIS or PC.
    Does it work now?

    Auto create channels feature doesn’t work for Modbus, unfortunately. The reason is that Modbus devices can contain different set of tags. You need to create channels manually. Use existing channels as templates. It is possible to clone them.

    12 should be entered in Address field of Devices table using SCADA-Administrator.
    40832 should be entered in the device template using SCADA-Communicator as described in the article.

    Each energy meter is a device (a one row in the appropriate table of DB).
    Address column should contain a Modbus address (or ID) of a device.
    Call number is filled by IP address for Modbus TCP or left empty for Modbus RTU.

    Object is a logical entity. For instance, a building or a house. Yes, it helps grouping of data and doesn’t affect communication with devices.
    A one object is enough for test purposes.

    Dear Joel,
    Step by step instructions are described in this article. If some details are not clear, ask about the particulars in the topic.

    I think that using more powerfull hardware will not solve the problem. Any application has to do a delays those allow other applications operating.
    Did you set 50 ms delay into Request Sequence?

    What protocols are used by your devices? May be it is better to develop native drivers instead of OPC?

    Please check load of your CPU. Probably, setting 50 ms delay in Request Sequence tab is a good idea.
    Data refresh frequency that equals 0 works within schemes but does not work within table views.
