    Hello Sir,

    I have install rapid scada in my pc. I want to send data to rapidscada from my RTU
    So, i have configure following in rapid scada
    TcpPort = 502
    InactiveTime = 60
    Behavior = Master
    ConnMode = Individual
    DevSelMode = ByIPAddress

    element group = 4byte float Holding register
    It works perfectly as below for tcp server and tcp client for master behaviour.

    Establish a TCP connection with xx.xx.xx.xxx:502

    2016-05-14 11:47:48 Communication session with the Device 41 “Test Device”, type: KpModbus, address: 1, call number: xx.xx.xx.xxx
    Request element group “Voltage”
    Send (12): 00 00 00 00 00 06 01 03 00 00 00 37

    I can see my meter’s data on web
    In tcp server and tcp client master behaviour, rapid scada send request.
    now, i want to read data of same meter from rapid scada using my other RTU. but, In both client and server connection scada send request. so, how its possible?

    When i configure behaviour slave it shows following error.

    2016-05-14 13:34:00 Initialize communication line 4 “Test line”
    2016-05-14 13:34:00 Load device template from file KpModbus_Aldc.xml
    2016-05-14 13:34:00 Error initializing communication channel: Slave behavior of the communication channel is not supprted by Device 41 “Test Device”

    Hello,
    If I understand you correctly, you need Rapid SCADA works as slave and your RTU as master. This mode is not supported for now, unfortunately.

    You should use another architecture of your system. As an option, you can use DBMS for integration or request your device by Rapid SCADA and by RTU in parallel.

    It is possible to develop the appropriate driver but it may be expensive depending on the project budget.

    Hi Mikhail,

    We need same thing Kajal asked you before. So RapidSCADA shouldn’t send request to RTU (Remote Terminal Unit). RTU should send request to RapidSCADA. You have answered in May 2016. that was not supported that time. Is it maybe supported now?

    Hi Marko,
    Nobody has purchased the development of this module yet. You can be the first 🙂
