    Hello Mikhail,

    I am trying to simulate , with modbus simulator ove modbus TCP/IP…. most of the time it gives communication error.

    1) scada server running is required all the time??

    2) mod simulator register value need to change to keep communication alive.

    3) error log say CRC error.

    How upload error log… I have tried capy paste … not working??

    Regards,

    You are requesting the same when the communication is OK and when it’s broken.
    It means that something wrong with a simulator application. May be some settings of the simulator were changed, e.g. device address.

    If you’d like to switch off SCADA-Server, you should uncheck Use SCADA-Server option in Communicator.

    I am increasing the word in simulation to change the 4X registers …. as u can see in the log…

    Now how to fetch the required information from this data…..

    voltage reg received is say (09 AC 74 47) , manufactrur says consider it as (P, Q, R , S), then apply formula (((256*P)+Q)+(R/256)+(S/(256*256)))/10 that is final voltage value 247.64 how to apply this formula and get value..

    Thanx

    You should use a formula of the appropriate input channel in SCADA-Administrator application.

    The formula below will be useful. Add it in the Formulas table and use in the formula of the input channel.

    public double GetByte(double val, int n)
    {
        UInt64 uintVal = (UInt64)val;
        return (uintVal >> (n*8)) & 0xFF;
    }
    

    The formula of the input channel is like

    (((256*GetByte(Cnl,3))+GetByte(Cnl,2))+(GetByte(Cnl,1)/256)+(GetByte(Cnl,0)/(256*256)))/10
    

    I haven’t tested it.

    Dear Mikhail ,

    I have tried it but it did not work.

    In formulas A pasted in source code section

    public double GetByte(double val, int n)
    {
    UInt64 uintVal = (UInt64)val;
    return (uintVal >> (n*8)) & 0xFF;
    }

    then in i/p channel formula

    (((256*GetByte(Cnl,3))+GetByte(Cnl,2))+(GetByte(Cnl,1)/256)+(GetByte(Cnl,0)/(256*256)))/10

    Communication log is as follows I have

    at formula of i/p channel but still no result,

    I think I have not understood how to use formula.

    Pls help how to go now,

    Thanx & Regards

    The formula is applied in SCADA-Server. That’s why you can’t see a result in Communicator. You have to configure displaying data by SCADA-Web app and you will be able to see calculation results.

    Hello Mikhail,

    thanx for reply, Its still not working,

    I think I have still not understood the basic working and interlinking of all the applications,

    For now i am trying to simulate server room:-

    t4 (10000 decimal) (Burnout4 is set to 1) and t5( decimal 11000) (Burnout5 is set to 1) values are received by scadacomm, and communication line 1 is bound to server, but in scada web i am not getting any update.

    I have tried generator of scada server, its work fine in web..

    but in normal comm process i am not getting scada web upgarede.

    Please suggest what to look for.

    Regards

    Can you see input channel numbers in the Channel column of Device Data page in Communicator? If not, it means that input channels are not bound to the device tags, so data are not passed from Communicator to Server.

    In channel column no input channel are displayed….

    I have tried services creating channels in scada admin but it says, error created channels are missing…

    How to resolve this…..
