Modbus or BACnet is just an instrument to collect data from devices. If you know what input and output signals are contained by your system, what sensors are required, then you can choose the most cheap and easy to use devices.

As for me, IoT is a beautiful word created for increasing sales. Anyway an automated system physically allows to do a set of measurements and receives a set of commands.

Hi,
SCADAMaster is the other software. We develop and support Rapid SCADA. If you decide to use Rapid SCADA, I can help you 🙂

[Mikhail]

The correct type, for example signalx= 311 (gauge32)

The issue is fixed. Please write me by email to send you an update.

[Mikhail]

Advantages depend on the user case. Could you describe your specific case to compare Modbus and BACnet?

[Mikhail]

Task of creating BACnet driver consists of 2 main subtasks:
1. Port BACnet stack to .NET or find the existing one.
As an idea you can use C++/CLI for porting.

2. Implement driver logic using Rapid SCADA base classes.
In this subtask I can help to explore the internal structure of Rapid SCADA source code.

For home automation the price of harware modules is important. Have you compared the prices of different hardware depending on communication interface and protocols?

C# is similar to C++ and Java. I think it is easy to start coding C# if you know C++ and Java.

[Mikhail]

I think it would only worth the effort if some additional functionality can be delegated to the device, like alarms or discovery of features etc.

Please provide more details about the idea.

What programming language you use to BACnet implementation? It is possible to see the source code on GitHub or somewhere else?

[Mikhail]

Raspberry Pi and other Linux systems are very popular. So drivers also should work on RPi under Mono .NET Framework.

[Mikhail]

It would be great ))
In terms of SCADA, communication with devices is implemented by drivers. In Rapid SCADA driver is .NET assembly, to put it simply, it is DLL written in C#.
I think, first of all you should see Modbus driver implementation on GitHub.

Let’s continue our communication.

Hi,

BACnet implementation is not currently in our plans. It can be included in the plans if we find a sponsor of this feature. Also I can help an external developer to integrate BACnet driver with Rapid SCADA if someone decides to develop it.

[Mikhail]

OLE DB connection is possible instead of ODBC.

[Mikhail]

Integration with Rapid SCADA article describes how to access to Rapid SCADA native data programmatically.

[Mikhail]

Rapid SCADA uses its own data format for storing archives by default.
May be for your task the optimal way is using standard DBMS. It depends on a way how data is processed and shown.
There is ModDBExport.dll – a SCADA-Server module. It allows online export data to Oracle, MS SQL, MySQL, PostgreSQL, etc. The examples of settings is in dbexport_en.pdf in the installation package.

Hello,

I think, comments should be inserted into event tables. The format of event tables allows to write 50 bytes of auxiliary event data. Is it enough? If it is not enough, another storage must be used.

Anyway custom development is required for the forms for entering data and showing inserted comments.

Could you provide more details of your question about SCADA-Administrator?
Also it is possible to use one of the popular DBMS to solve your task.

[Mikhail]

The normal call stack is UserData.GetUserData() -> AppData.InitAppData()
Then MainData.SettingsFileName = ConfigDir + CommSettings.DefFileName;

Is MainData.SettingsFileName = … executed?

[Mikhail]

Check why serverComm == null in MainData.CheckUser() after executing MainData.RefrServerComm() method.
