    Dear Sirs,

    1、How to get the data which automatically sent by the devices?

    2、How to get the data which is not sent by the standard Modbus commands other than the other device defined commands, such as “?”, “Q”, etc…?

    1. Could you provide an example, please?
    2. Probably you should implement or purchase development of the device driver if your device uses its own communication protocol.

    For example:

    1. A device with RS232 serial port, send the data to the PC by press the button at the device, and it does not support sending command to return a data.
    2. A device with RS232 serial port, if PC send a command [“Q” + \r\n] to it with RS232 protocol, then it will return the real data.
    3. A device with TCP/IP port, if PC send a command [“Q” + \r\n] to it with TCP protocol, then it will return the real data.

    How to meet the above requirements by RapidSCADA with its settings?

    Special device driver is needed. Driver development is described here http://rapidscada.org/device-drivers-development/
    You could develop it by yourself or purchase it.

    Hello,

    I am new here. And also new (first-time user) in Scada. So myquestions could look a bit… silly 🙂

    I hawe few questions:
    1. is Rapid SCADA able to run on a Raspberry Pi Zero? The small one with integrated Wifi capabillity. Well, this I could test myself, but I am not familiar with SCADA of any type (yet), so it is better to ask You..

    2. is it possible for Rapid SCADA to fetch and use data from Raspberry’s RS232 port. I do have an AVR controller controling my house heating and it is sending the data over RS232 to a Raspberry. Sended / Fetched data looks like this:

    00002:26:45	00002:26:45	00002:26:45	
    00.00.00 00:00:00	0350	0455	0310	0291	X-------	--------	00002:26:45	00002:26:45	00002:26:45	00002:26:45	

    this is date and time data, temperatures, and data representing the state / status of controller with the “x” and “-” strings.
    The data is sended in, let’s say 5 minutes interval. The data represented is an ASCII data, delimited with TAB, and at the end there is a CR/LF symbol. It can easilly be imported to Excell or Calc in Linux.

    Controller is my own product, so I can (possibly) change the format of sended data…

    3. Can Rapid SCADA send ASCII string over RS232?

    THX in advance and greetingh from Slovenia

    Hi,

    is Rapid SCADA able to run on a Raspberry Pi Zero?

    I tested Rapid SCADA on RPi 3. I suppose, Pi Zero should work.

    is it possible for Rapid SCADA to fetch and use data from Raspberry’s RS232 port.

    Most likely. You should find the port name by Linux tools and specify it in Communicator settings.
    If you use non standard communication protocol (as you shown), you need to develop a driver (DLL) for Rapid SCADA.

    Can Rapid SCADA send ASCII string over RS232?

    In general, yes. But in automation, there are various of protocols.

    Please create new topics for new issues.

    Hi Mikhail,

    I want to send data from my remote devices to scada in http format and that data should be stored in database. Please Help me out.

    Thank you.

    Hi,
    HTTP is generic. You should specify your own REST API and then develop the appropriate driver for Communicator. We can do this for you.
    Why do you prefer HTTP in your case?
