    Hi all,

    I have made a BACnet KP for Rapid Scada to work with BACnet devices.
    It’s support BACnet IP devices and gateway (only IPV4 and not support MSTP).
    You can download the kp here
    If you want to purchase the KP, please contact me at tiger.scada@gmail.com.
    Any question, please post here or send me an email.

    Regards

    Hi,

    I have made a BACnet KP for Rapid Scada to work with BACnet devices.

    Great!

    May I ask a few questions:
    1. Why do you include ScadaCommCommon.dll and ScadaData.dll into the archive? Is it possible to remove them because they are already exist in the destination directories?

    2. What is the pricing? Which license types are available?

    3. May be it would be useful if you add version number in the archive name, e.g. KpBACnet_5.0.0.0.zip

    We would be glad to publish your driver in the repository after clarifying the above questions.

    Dear Mikhail,

    1. Why do you include ScadaCommCommon.dll and ScadaData.dll into the archive? Is it possible to remove them because they are already exist in the destination directories?
    >> The ScadaCommCommon must change, because I have changed some code in the UDPTransport so it can work with BACnet, ScadaData can remove.

    2. What is the pricing? Which license types are available?
    >> The price is 180$/license and full support in 1 years. User can run it in demo mode for 10 minutes, after 10 minutes, need to restart the communication line.

    3. May be it would be useful if you add version number in the archive name, e.g. KpBACnet_5.0.0.0.zip
    >> OK, I will add version to it.

    Dear Mikhail,

    I have changed the archive name to KpBACnet_1.1.0.0.zip.

    The ScadaCommCommon must change, because I have changed some code in the UDPTransport so it can work with BACnet, ScadaData can remove

    If every driver had its own ScadaCommCommon.dll, it would be impossible to use the software. We should merge the changes if they are compatible, or the UDP implementation should be made inside the driver. Could you show what was changed in ScadaCommCommon?

    Note: In the version 6, you can add new communication channels to resolve such cases easier.

    Dear Mikhail,

    The BACnet IP is run in UDP/IP, and if there are BACnet MS/TP controllers connect to server via a BACnet gateway, all the controllers will run through a same IP address.
    Your CommUdpLogic only support to process incoming data the first KPLogic, so I must change to process incoming data for all KPLogic of the IPAddress.

    Origin:
    KPLogic kpLogic;
    if (kpCallNumDict.TryGetValue(udpConn.RemoteAddress, out kpLogic))
    {
    // обработка входящего запроса для определённого КП
    ExecProcIncomingReq(kpLogic, buf, 0, buf.Length, ref kpLogic);
    }
    else
    {
    WriteToLog(string.Format(Localization.UseRussian ?
    “{0} Не удалось найти КП по IP-адресу {1}” :
    “{0} Unable to find device by IP address {1}”,
    CommUtils.GetNowDT(), udpConn.RemoteAddress));
    }

    Change to:
    foreach (var _kpLogic in kpCallNumDict.Where(x => x.Key == udpConn.RemoteAddress))
    {
    var kpLogic = _kpLogic.Value;
    ExecProcIncomingReq(kpLogic, buf, 0, buf.Length, ref kpLogic);
    }

    Regards

    Dear,

    I also change the type of the kpCallNumDict to List

    // protected Dictionary<string, KPLogic> kpCallNumDict;
    protected List<KeyValuePair<string, KPLogic>> kpCallNumDict;

    Thanks

    Hello,

    I will analyze this and reply here.

    Hello,

    If all the controllers have the same IP address, you should choose communication channel properties:
    Device selection = DLL Determined

    In this case the other branch of code works:

    else // DeviceSelectionModes.ByDeviceLibrary
    {
        // обработка входящего запроса для произвольного КП
        KPLogic targetKP = null;
        ExecProcIncomingReq(firstKP, buf, 0, buf.Length, ref targetKP);
    }

    When you override the ExecProcIncomingReq method, you should return the proper device in the targetKP variable. There is a property CommLineSvc that implements the ICommLineService interface.
    By using CommLineSvc.FindKPLogic(int address, string callNum) you can find the required device.

    Could you use the described approach?

    kpLogic = CommLineSvc.FindKPLogic(...);
    // decode received data here
    kpLogic.SetCurData(...);

    Hi Mikhail,

    Let me check again.
    Can I get the list of KP from CommLineSvc?

    Regards

    Hi,
    You can get a list, but you can find a device (KP) by a numerical address or string address (CallNum).

    Could you explain, how do you detect that an UDP packet is addressed to a particular device (KP)?

    Hi,

    It’s BACnet protocol. In the message, it contains the full address of the device (there are multiple address in one device). I found it’s difficult to locate the device only by address and callnum, because after the initialization, the address won’t appear on the packet.

    Thanks

    Hi,

    Please provide an example what do you get after decoding an incoming BACnet message?
    May be I should apply the suggested updates, may be not. To do this I have to be sure that they are really necessary there.
